SECTION 3.7.6
LADDER SAFETY
Introduction
The use of ladders puts workers in a potentially unsafe position. Ladders are used for many
purposes but no matter what type of ladder you use or what you use it for, it pays to take some
extra precautions. Any fall can be serious, and a fall from the height of even a low ladder can
mean a painful and incapacitating injury.
Purpose
In response to this risk, the procedure for Safe Use of Ladders has been developed and
implemented, in consultation with the Facility Services Joint OH&S Committee, in order to
comply with the requirements of Workers Compensation Act, Part 1, Section 115 (1), (2) (b)(f).
The procedure is to be followed by all workers employed by School District No.23 (Central
Okanagan) and must be reviewed with workers by the Department Coordinator/Principal during
the ‘Worker Orientation’ and at the inception of the procedure.
As the majority of school sites within our district are equipped with roof access ladders inside
the buildings, they must be used whenever possible. A fixed ladder is much safer, generally,
than a portable ladder would be and convenience must have less bearing on a decision than
safety. Portable ladders are not to be used unless a safer route of access to a roof is not
available. It is also a requirement of this procedure that all precautions for the proper use of fall
protection be used in accordance with the WCB Act and the Regulations as well as with the
Facility Services procedure on Fall Protection.
Definitions
The “Board” means the Workers Compensation Board;
The term ‘District Approved’ means approved by School District No.23 for use by employees;
A “Competent Person” means a person deemed competent by the Board and School District
No.23.
A “worker” includes:
 any person who is in a contract of service or apprenticeship, written or oral, expressed
or implied;
 any learner who, although not under a contract of service or apprenticeship, becomes
subject to the hazards of an industry while undergoing training or probationary work
specified or stipulated by the employer as a preliminary to employment;
 any person working with or without remuneration;
 any independent operator admitted by the board, who is neither an employer nor a
worker;
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders


any person enrolled in a vocational or training program approved by the Minister of
Education, Skills and Training and the Minister of Labour, and attending the program
at its designated location, when deemed a worker by the board at the request of either
minister.
Point of Access – All areas used by employees for work-related passage from one area or
level to another.
Portable Ladder – A ladder that can be readily moved or carried.
Procedure
STRAIGHT AND EXTENSION LADDERS
To raise a ladder,
 Brace the lower end against a wall and then grasp the top rung with both hands. Raise
the top end and walk underneath the ladder, down the rungs until the ladder is vertical.
When using an extension ladder,
 Raise it to the desired height, being sure the locks engage properly
on both sides of the ladder. To position the ladder properly, place it
against the wall so the distance between the wall and the base of
the ladder is ¼ of the length along the ladder from the base to its
point of support (¼ of its working length). Since the rungs on
ladders are normally one foot apart, the approximate distance is
easy to compute.
 Fall Protection must be used when working above 3 Meters (10
feet) unless the work will be of short duration.
 The ground under the ladder should be both level and firm. Large
flat wooden boards placed under the ladder can level a ladder on
uneven ground or give a ladder better footing on soft ground. If
possible, secure the ladder.
 When portable ladders are used for access to an upper landing
surface, the side rails must extend at least 3 feet (.9 m) above the
upper landing surface.
 Ladders must be secured when used at heights above 10’. Have someone hold the
bottom of the ladder or tie it off at the roof level.
 If the ladder is to be tied off, it must be done in a way that does not create a tripped
hazard to the user. (i.e.: Buckles from tie downs should be located in the middle of the
ladder rather than on the side.)
When approaching a ladder for descent from a roof, always:
 Approach from the center.
 Hold the ladder with both hands before attempting to mount the ladder.
 Step around the ladder with one leg and place that foot on a rung, which is lower than the
ladder’s point of contact with the roof.
 Place the other foot on the ladder and proceed to descend with three points of contact at
all times.
 Never carry heavy equipment on the ladder with you. Use hoisting materials wherever
possible.

STEPLADDERS
Many of the suggestions for using straight and extension ladders also apply to stepladders.
When using a stepladder,
 Never carry heavy equipment on the ladder
with you. Using hoisting materials such as a
tool belt or hand line wherever possible.
 Erect a stepladder only on a flat level surface.
Do not place it on a table or any similar
platform for added height.
 Never use a stepladder as a straight ladder.
 Before climbing a stepladder, make sure that
its legs are fully extended and the spreader
locked. The locking device on some ladders
may present a pinching hazard, so keep
fingers clear when setting up the ladder.
 Never stand on the top two steps of a
stepladder.
 Do not step on the bucket shelf or attempt to
climb or stand on the rear section supports.
They are not designed to support the weight of
a person.
 Fall Protection must be used when working
above 3 Meters (10 feet) unless the work will be of short duration.
Finally, no matter what kind of ladder you are using, never leave a raised ladder unattended. It
could fall unexpectedly and injure someone.
General Precautions for the Safe Use of All Ladders










Ladders must be maintained free of oil, grease, and other slipping hazards.
Wooden ladders must not be painted as this could hide flaws or damage of the ladder.
Ladders must not be loaded beyond their manufacturer’s rated capacity.
Ladders must be used only for the purpose for which they were designed.
Non-self-supporting ladders must be used at an angle where the horizontal distance from
the top support to the foot of the ladder is approximately one-quarter of the working
length of the ladder.
Fixed ladders must be used at a pitch no greater than 90 degrees from the horizontal,
measured from the backside of the ladder. Above 8’, ship’s ladders should be installed
with slip resistant steps and handrails as required.
Ladders must be used only on table and level surfaces unless secured to prevent
accidental movement.
Ladders must not be used on slippery surfaces unless secured or provided with slipresistant feet to prevent accidental movement. Slip-resistant feet must not be used as a
substitute for the care in placing, lashing, or holding a ladder upon slippery surfaces.
Ladders placed in areas such as passageways, doorways, or driveways, or where then
can be displaced by workplace activities or traffic must be secured to prevent accidental
movement or a barricade must be used to keep traffic or activities away from the ladder.
The area around the top and bottom of the ladders must be kept clear.







The top of a non-self-supporting ladder must be placed with two rails supported equally
unless it is equipped with a single support attachment.
Ladders must not be moved, shifted, or extended while in use.
Ladders must have non-conductive side rails if they are used where the worker or the
ladder could contact exposed energized electrical equipment.
Cross-bracing on the rear section of stepladders must not be used for climbing unless the
ladders are designed and provided with steps for climbing on both front and rear
sections.
Ladders must be inspected by a competent person for visible defects on a periodic basis
and after any incident that could affect their safe use.
When ascending or descending a ladder, the worker must face the ladder and must use
at least one hand to grasp the ladder while climbing.
A worker on a ladder must not carry any object or load that could cause him/her to lose
balance and fall.
Other points to remember when using a ladder are:
 Never carry heavy equipment on the ladder with you. Using hoisting materials such as a
tool belt or hand line wherever possible.
 Never use a ladder in a strong wind.
 The point where the ladder rests against the wall should be flat and firm.
 A ladder should not be placed in front of a door that is not locked, blocked or guarded.
 Before positioning the ladder, check for insect or bird nests under the eaves; the top of a
ladder is no place to discover a wasp nest.
 Tools should be carried in the pockets, in a bag attached to a belt, or raised and lowered
by rope. Be sure that the soles of your shoes are clean and dry.
 Work facing the ladder, holding on with one hand. If it is ever necessary to work with both
hands, hook one leg over the rung.
 Don’t lean too far to the side while working. A good general guide is to keep your body
centered between the rails of the ladder. Instead of leaning to the side, get down and
move the ladder.
 In case of sudden dizziness or a panicky feeling, bow your head, drape both arms over
the rung in front of you, close your eyes, and wait until the feeling passes.
 Do not use a ladder as a scaffold or for any purpose except what was intended.
 Many fatalities occur when a metal ladder brushes against power lines while being
moved. Use only double-insulated or properly grounded electrical tools on a metal ladder.
To be safer, use only a dry wooden or non-conductive fiberglass ladder when working
around electrical wires or equipment.
Maintenance & Structural Defects
 Portable ladders with structural defects – such as broken or missing rungs, cleats, or
steps, broken or split rails, corroded components, or other faulty or defective components
– must immediately be marked defective, or tagged with “Do Not Use” and withdrawn
from service until repaired.
 Fixed ladders with structural defects – such as broken or missing rungs, cleats, or steps,
broken or split rails, or corroded components – must be withdrawn from service until
repaired.
 Defective fixed ladders are considered withdrawn from use when they are:
a) immediately tagged with “Do Not Use”;
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
5


b) marked in a manner that identifies them as defective;
c) blocked – such as with a plywood attachment that spans several rungs.
Ladder repairs must restore the ladder to a condition meeting its original design criteria
before the ladder is returned to use.
Major repairs to portable ladders will not be performed. Ladders are to be replaced and
not re-used. The damaged ladder must be destroyed prior to disposal.
Ladder Logs
At the time of inspection, we suggest you start/create a maintenance log for each ladder. We
suggest you do your general maintenance at least monthly. General maintenance for ladders is
a simple process of taking a little time to visually inspect all the parts, beams, fasteners and
rungs for damage or wear.
This log can then be used to supplement your annual testing log for each ladder and will
provide a useful history to be able to track any and all ladder damages or repairs that may
happen. Provide one log for each ladder.

Aluminum Ladders:
(Conducts electricity.)
Soap and water works well – Aluminum is a malleable metal and is subject to dents and nicks
etc. Note: Small dents and/or nicks on the beams and rungs are not uncommon and are not a
cause for alarm. If there are any concerns about dents, etc., do a load test to be sure the dents
are not serious. Be sure to record the location and size for future reference. Be sure rungs are
all tight as the rung to rail joint is the only thing that holds the two beams together. If any rung is
loose – remove the ladder from service and repair before further use.
Fiberglass Ladders:
(Non-conductive)
Soap and water works well – Fiberglass is not malleable and does not dent; however, nicks and
scratches and scrapes can be very common. If there are any doubts, do a load test to be sure
the nicks and scratches are not serious. Repairs of small surface nicks and scratches generally
require only slight sanding of same and an application of clear epoxy glue to the nick or scratch.
Be sure to sand smooth after the glue dries. Note: This type of repair is only to be used for
small surface scratches, etc. and only after a load test has been passed.
Wood Ladders:
(Non-conductive)
Soap and water works well – Wood rails and wood rungs expand and contract with changes of
both humidity and temperatures. Because of this problem, it is very important that rung tightness
is checked regularly and any and all rung tie rods be checked to be sure they are tight.
Remember: Only the rung to rail joint holds the side beams together. In cold regions of the
country the heat from buildings causes the rungs to become loose as the wood shrinks from the
loss of moisture.
Wood Beam Truss Models: These wood models are constructed with top and bottom wood
pieces and truss blocks/rung blocks between the top and bottom wood truss rails. Warning: The
wood joints/glue joints between the blocks and strips are very likely to fail if the bolts and nuts
are not kept tight. Be sure these bolts are tight before any load testing is ever done.
Remember: It is 4 times harder to carry the load horizontally/flat than it is at 75 degrees or in
erected position.
The visual inspection part of your maintenance program becomes very important on any wood
ladder as most noticeable damaged areas require immediate attention and repair just to
maintain the varnish finish and keep the wood from deteriorating.
Only a load test can tell you if the ladder can still
carry the load it was designed to carry and only a
500 lb center load test can tell if the ladder has a
4:1 safety factor.

Roof Ladders:
Maintenance on roof ladders is the same as already covered under the previous sections. Refer
to the proper section that covered the type of material you have in service.
Folding Ladders:
Maintenance is the same as the general maintenance covered earlier – refer to the proper
section covering the type of material that is in service. When these rung mounting rivets become
sloppy and loose, we suggest you replace the ladder as these rivets are brass and are meant to
provide a hinge/bearing assembly for this folding rung assembly. Be sure the lock assembly is
also tight and properly locks the ladder in the open position. These lock assemblies can be
tightened – carefully – with a hammer and punch.
A-Frame/Combination Ladders:
Refer to the proper section that covered the type of material you have in service. Inspect the
hinge hardware and fasteners and replace anything that appears to be worn, damaged or rusty.
A few drop of any type of oil works well on the hinges and of course, soap and water works well
on all the other parts. Check the spreader arms, bars and parts to be sure everything still works
and fits together properly. These parts are vital in the A-frame position and must be able to
properly engage before the ladder would be safe to use in the A-frame position.
35-A Jackknife Locks:
These locks must be engaged before using the ladder as a single ladder. Note that the hinge of
this model must be under the ladder/bottom side as you climb to be in the proper use position.
This allows the butt ends of the rails to pinch together under load rather than allowing the entire
load to be on the locks. Use with the hinge on top of the rails is not safe.
Ladder Parts/Accessories:
Ladder locks/Pawls:
Spring operated, automatic lock assemblies that engage and lock upper sections to lower
sections, always operating in pairs.
1. Lock housing & cover plate (not shown)
3. Finger (note position)
5. Mounting bolt holes
2. Lock hook
4. Spring
6. Shoulder bolt hole
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
8
These lock assemblies always have a rung mounted between them. This rung that is used
between the locks is the only rung (except for some roof hook models) that is not fastened to the
side rails. A special rung mount bracket is used because these rungs are not mounted to the
side rails. The rung is fastened to this by 4 each rivet, which must be removed and replaced if
the locks are removed. Note: Lock assemblies are to be tight, but the housing can be crushed
and the lock parts pinched if the mounting bolts are over-tightened. Flush the housings with
soap and water and apply some oil to the pivot points prior to returning the ladder to service.
Prong Feet/Spikes/Butt Spurs and End Caps:
These parts are either aluminum or steel and are fastened to the side rails with rivets and/or
bolts. Check these parts for shape and tightness and replace or tighten as needed when
checking the rest of the ladder assembly. Bolts and rivets have been know to be sheared off
and/or loosen after walking a ladder or using it to break windows and doors.
Safety Shoes:
A rubber padded extra swivel foot or shoe mounted to the bottom of the section. These rubber
safety shoes are offered as a ladder option to the standard prong foot/spike. The rubber safety
shoe is meant to be used on hard, smooth surfaces where spikes may slip because they cannot
dig in. These safety shoes also may rust, and because of this, they require cleaning and
checking at least yearly.
Pulleys and Halyards:
All larger extension ladders are supplied with halyards (rope) and pulleys so the upper sections
can be easily extended.
Pulleys:
The present pulleys are all aluminum with brass oil-lite bushings supplied either as single or
double sheave. Cleaning and oiling of pulleys is a good idea – recommended once a year.
Halyards/Rope:
The rope continually wears rapidly. If in doubt, always replace the rope.

Training Requirements
The employer is required to provide training for each worker using ladders. The program must
enable each employee to recognize hazards related to ladders and to use proper procedures to
minimize these hazards. Each worker is to be trained by a competent person in the follow areas,
as applicable:
 the nature of fall hazards in the work area;
 the correct procedures for erecting, using, maintaining, and disassembling the fall
protection systems to be used;
 the proper use, placement, and care in handling of all ladders; and
 the maximum intended load-carrying capacities of ladders used.
Employees will be evaluated on their competency before being allowed to use ladders in the
field. In addition, the employer must re-train each employee as necessary to maintain the
understanding and knowledge acquired through compliance with the standard.

Portable Ladder Safety: Selection, Use, and Maintenance
These safety rules are a combination of OSHA regulations and proven
commonsense procedures. This combination of safe equipment and its
safe use can eliminate most ladder accidents.
Ladder Selection
1. Be sure the ladder being used has the proper duty rating to carry the
combined weight of the user and the material being installed.
2. A ladder’s duty rating tells you its maximum weight capacity. There are four categories of
duty ratings:
3. Type IA and Type I ladders are the only acceptable ladders on a construction jobsite.
4. The American National Standards Institute (ANSI) requires that a duty rating sticker be
placed on the side of every ladder so users can determine if they have the correct type
ladder for each task/job.
5. Be sure that metal steps and rungs are grooved or roughened to prevent slipping.
6. Use the proper size ladder for the job. The average craftsman will generally work most
comfortably at his shoulder level, which is about 5 feet above where he stands. Since the
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
13
craftsman must stand at least 2 feet down from the top of a ladder, the maximum working
height would be about 3 feet above the top of the ladder or 5 feet minus 2 feet. For example,
a 5-foot stepladder would give an effective working height of 8 feet or 5 feet plus 3 feet.
When using straight or extension ladders, the craftsman stands 3 feet down from the top,
which gives an effective working height of 2 feet above the ladder top.
Ladder Inspection
1. Always check a ladder before using it. Inspect wood ladders for cracks and splits in the
wood. Check all ladders to see that steps or rungs are tight and secure. Be sure that all
hardware and fittings are properly and securely attached. Test movable parts to see that
they operate without binding or without too much free play. Inspect metal and fiberglass
ladders for bends and breaks.
2. Never use a damaged ladder. Tag it “Defective” and report it to the boss so that it may be
removed from the job.
Ladder Setup
1. Place ladder feet firmly and evenly on the
ground or floor. Make sure the ladder is sitting
straight and secure before climbing it. If one foot
sits in a low spot, build up the surface with firm
material.
2. Do not try to make a ladder reach farther by
setting it on boxes, barrels, bricks, blocks or
other unstable bases.
3. Do not allow ladders to lean sideways. Level
them before using.
4. Brace the foot of the ladder with stakes or place
stout boards against the feet if there is any
danger of slipping.
5. Never set up or use a ladder in a high wind,
especially a lightweight metal or fiberglass type.
Wait until the air is calm enough to insure safety.
6. Never set up a ladder in front of a door unless the door is locked or a guard is posted.
7. Do not use ladders on ice or snow unless absolutely necessary. If they must be used on ice
or snow, use spike or spur-type safety shoes on the ladder feet and be sure they are
gripping properly before climbing.
8. Use Safety shoes on ladder feet whenever there is any possibility of slipping.
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders

Ladder Climbing and Standing
1. Keep the steps and rungs of ladders free of grease, oil, wet paint, mud, snow, ice, paper and
other slippery materials. Also clean such debris off your shoes before climbing a ladder.
2. Always face a ladder when climbing up or down. Use both hands and maintain a secure grip
on the rails or rungs.
3. Never carry heavy or bulky loads up a ladder. Climb up yourself first, and then pull up the
material with a rope.
4. Climb and stand on a ladder with your feet in the centre of the steps or rungs.
5. Do not overreach from a ladder, or lean too far to one side. Overreaching is probably the
most common cause of falls from ladders. A good rule is to always keep your belt buckle
inside the rails of a ladder. Work as far as you can reach comfortably and safely, then move
the ladder to a new position.
6. Never climb onto a ladder from the side, from above the top or from one ladder to another.
7. Never slide down a ladder.
Proper Use of Ladders
1. Never use metal ladders around exposed electrical wiring. Metal ladders should be marked
with tags or stickers reading “CAUTION – Do Not Use Around Electrical Equipment” or
similar wording. RULE of THUMB: If the overhead power line is 50kV or less, then stay at
least 10 feet away. For everything else, keep at least 35 feet away.
2. When using a ladder where there is traffic, erect warning signs or barricades to guide traffic
away from the foot of the ladder. If this is not possible, have someone hold and guard the
bottom of the ladder.
3. Do not try to move a ladder while you are on it by rocking, jogging or pushing it away from a
supporting wall.
4. Never use a ladder when under the influence of alcohol, on drugs or medications, or in ill
health.
5. If you get sick, dizzy or panicky while on a ladder, do not try to climb down in a hurry. Wait.
Drape your arms around the rungs; rest your head against the ladder until you feel better.
Then climb down slowly and carefully.
6. Do not leave tools or materials on top of ladders. If they fall on you, you can be hurt. If they
fall on someone else, your company can be sued.
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
15
7. Never push or pull anything sideways while on a ladder. This puts a side load on the ladder
and can cause it to tip out from under you.
8. Allow only one person at a time on a ladder unless the ladder is specifically designed for two
people.
9. Never use a ladder as a horizontal platform, plank, scaffold or material hoist.
10. Be cautious about homemade ladders. Never use ladders made by fastening cleats across a
single narrow rail, post or pole.
11. Never use a ladder on a scaffold platform. If you can’t reach, the scaffold should be higher.
Proper Ladder Care and Storage
1. Keep all ladder and their accessories, especially safety shoes, in good condition.
2. Wood ladders, which are to be used outside, should be treated to prevent weather damage.
A clear finish or transparent penetrating preservative should be used. Linseed oil is a good
treatment for a wood ladder, although it does add some weight to a ladder. An oil treatment
also helps to rustproof the metal parts of a wood ladder.
3. Never paint a wood ladder. This will cover dangerous cracks or fill and hide them.
4. Never sit on ladder side rails.
5. Never use a metal or fiberglass ladder which has been exposed to fire or strong chemicals, it
should be discarded.
6. Never store materials on a ladder.
7. Store wood ladders where they will not be exposed to excessive heat or dampness. Store
fiberglass ladders where they will not be exposed to sunlight or other ultraviolet light sources.
8. Be sure that ladders are properly supported and secured when in transit. Vibration and
bumping against other objects can damage them.
9. Store ladders on racks, which give them proper support when not in use.
Additional Safety Rules for Stepladders
1. Never use a stepladder over 20 feet long.
2. Always open a stepladder completely and make sure the spreader is locked open before
using the ladder.
3. Never substitute makeshift devices of wire or rope for stepladder spreaders.
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
16
4. Do not stand higher than the second step from the top of a stepladder.
Especially, do not stand or sit on the top cap, or stand on the pail shelf, or
on the back of a stepladder.
5. Do not straddle the front and back of a stepladder.
Additional Safety Rules for Single Ladders and Extension Ladders
Ladder Selection and Inspection
1. Remember that the sections of an extension ladder should overlap enough to retain the
strength of the ladder using the following table:
Length of Ladder
Up to 36 feet
Over 36 to 48 feet
Over 48 to 60 feet
Required Overlap
3 feet
4 feet
5 feet
Of course, the usable length of the ladder is shortened by the amount of the overlap.
2. Never splice or tie two short ladders together to make a long section.
3. Top support for a ladder is as important as good footing. The top should rest evenly against
a flat, firm surface. If a ladder is to be leaned against roof gutters, the strength and stability of
the gutters should first be tested.
4. When a ladder is used for access to an upper
landing surface, it must extend three rungs, or at
least three feet above the landing surface.
5. A ladder used for access to an upper landing
surface should be secured against sideways
movement at that top or held by another worker
whenever it is being used.
6. Extend an extension ladder only from the ground.
Determine the needed height, extend and lock the
fly section securely in place then set it up against
the wall. Check for stability and support before
climbing.
7. If possible, the base of a long ladder should be
secured to the ground and the top should be tied to
the upper landing surface.
8. The technically proper angle for a non-selfsupporting ladder is about 75 degrees above
horizontal. This means that the base should be set out one-fourth of the ladder’s height to its
top support point. For example, if a ladder is to be supported at a point 20 feet of the ground,
its base should be set 5 feet out from the wall (20 feet divided by 4=5 feet). An easy way to
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
17
measure this, if the ladder top will rest against the wall, is to pace off the length of the ladder
or count the rungs, and divide by four to get the proper distance from the wall for placing the
foot of the ladder.
9. If ladders are set up at a steeper angle than 75 degrees above horizontal they are more
likely to tip backward in use. As a minimum they must be tied off at the top to prevent this
from happening.
10. If ladders are set up at an angle less than 75 degrees above horizontal they are more likely
to slide out from the bottom. Safety ladder shoes or base typing is a must in this case.
11. The distance from the foot of a ladder to the wall should never be more than one-half the
height to the support point, an angle of about 63 degrees above horizontal. Otherwise, more
strain will be put on the side rails than they are designed to carry.
Ladder Climbing and Standing
(a) Never stand on the two top rungs of a straight or extension ladder.
Proper Ladder Care and Storage
1.
Metal bearings of extension ladder rung locks and
pulleys should be lubricated periodically, and
between regular maintenance periods whenever
necessary.
2.
Ropes on extension ladders should be in good
condition. If they become frayed or badly worn,
replace them.
Setting Up a Straight or Extension Ladder
It is very important to learn the proper methods for
setting up ladders. Unless setting up is done correctly,
it can cause damage to the ladder and excessive
physical strain on the user.
Step 1: Lay the ladder on the ground with the base
resting against the bottom of the wall and the top
pointing away from the wall.
Step 2: Starting at the top of the ladder, lift the end over your head and walk under the ladder to
the wall, moving your hands from rung to rung as you go.
Step 3: When the ladder is vertical, and the top touches the wall, pull out the base so that the
distance away from the wall is about one-fourth of the height to the point of support.
Facility Services Safe Operating Procedure No. 0005

Step 4: Reverse this process to take down the ladder. Remember that you will be walking
backwards, so check for obstacles in your path before starting. Also be careful to lower the
ladder slowly so that you can keep it under control and prevent its falling on you.
LADDER SAFETY
Portable Ladders
Falls from portable ladders are a major source of serious injury. Be aware of the hazards and take proper
precautions to prevent falling.
What to do before use:
√
√
√
√
√
√
√
√
√
√
√
Inspect the ladder before and after each use.
Reject and tag any ladders that have defects. Have faulty ladders repaired or thrown out.
Use a ladder-designed for your task. Consider the strength, type, length and the Canadian Standards
Association (CSA) approval.
Get help when handling a heavy or long ladder.
Keep ladders away from electrical wires.
Tie off ladders at the top and secure bottom to prevent them from slipping.
Set up barricades and warning signs when using a ladder in a doorway or passageway.
Before mounting a ladder, clean the boot soles if they are muddy or slippery. Avoid climbing with wet
soles. Ensure that footwear is in good condition.
Face the ladder when going up or down and when working from it.
Keep the centre of your body within the side rails.
Refer to safety regulations for specific measurement requirements.
What to avoid:
√
√
√
√
√
√
√
Do not use a ladder in a horizontal position as a scaffold plank or runway.
Do not carry objects in your hands while on a ladder. Hoist materials or attach tools to a belt.
Do not work from top three rungs. The higher a person goes on a ladder, the greater the possibility
that the ladder will slip out at the base.
Do not use items such as a chair, barrel or box as a makeshift ladder.
Do not use a portable ladder when other equipment is available. Replace a ladder with a fixed
stairway or scaffold.
Do not join two short ladders to make a longer ladder. Side rails are not strong enough to support the
extra load.
Do not paint wooden ladders. Defects may be hidden by the paint. Wood
preservatives or clear coatings may be used.
Climbing a ladder:
√
√
√
√
Check for overhead electrical wires before setting up a ladder.
Clear the area around base and top of the ladder of debris, tools and
other objects.
Tie off yourself with a safety harness when working 3 m (10ft) or more
off the ground or when working with both hands.
Ensure that only one person is on a single-width ladder. Only one person
is allowed on each side of a double-width ladder.

√
√
√
√
√
√
√
√
√
Maintain three-point contact by keeping two hands and one foot, or two feet and one hand on the
ladder at all times.
Grasp the rungs when climbing a ladder, not the side rails. If your foot slips on a ladder, holding onto
rungs is easier than holding onto the side rails.
Wear protective footwear with slip-resistant soles and heels.
Ensure that all electrical equipment used during ladder work is in good condition and properly
grounded.
Rest frequently to avoid arm fatigue and disorientation when the work requires you to look up and
reach above your head.
Drape your arms over a rung and rest your head against another rung or side rail if you become dizzy
or panicky. Climb down slowly.
Do not use a ladder in passageways, doorways, driveways or other locations where a person or
vehicle can hit it. Set up suitable barricades or lock the doors shut.
Do not place a ladder against flexible or moveable surfaces. Do not straddle the space between a
ladder and another object.
Do not erect ladders on boxes, carts, tables, scaffold or other unstable surfaces.

√
√
√
√
Return ladders to the storage area after use.
Store ladders where they are protected from
the weather.
Support ladders horizontally on racks. To
prevent sagging, support ladders every 2 m
(6 ft).
Keep ladders clean and free of foreign
materials.
Ensure that storage areas are easy to reach.
Keep wooden ladders in a well-ventilated location, away from dampness and excessive heat.
Avoid long overhangs beyond support points when transporting ladders on vehicles.
Pad racks on vehicles with soft material to reduce wear and road shocks.
Tie ladders to each support point to reduce damage.
Mark ladders which overhang vehicles with a red or orange flag.
Grasp ladders near the centre when carrying them.
Use caution carrying ladders through passageways, doorways, or any place where your view is
obstructed.
Use a partner to help carry long or heavy ladders.
Ensure that you and your partner are on the same side
when carrying a ladder. Stay in step. Work out in advance
any hand or voice signals to coordinate stopping or
changing direction.
Do not hang ladders from rails or rungs.
Do not store materials on ladders.
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
20
√ Do not expose fiberglass ladders to excessive temperatures (above 93oC or
200oF)
√ Do not hold the front of ladders at head level when carrying them.
√ Do not expose plastic reinforced ladders to excessive sunlight. Ultraviolet
light may cause the plastic resins to degrade. If the strength of the ladder is
questionable, replace the ladder.
Securing a Ladder:
√ Rest the top of the ladder against a solid surface that can withstand the load.
√ Attach a ladder stay across the back of a ladder where a surface cannot
stand the load. Extend the stay across a window for firm support against the
building
walls or window frame.
√ Guard or fence off the area around a ladder erected in an area where
persons
have access.
√ Secure the ladder firmly at the top to prevent it from slipped sideways or the
foot from slipping outwards.
√ Station a person at the foot of a ladder when it is not possible to tie at the top
or secure it at the foot.
√ This is effective only for ladders up to 5m (16 ft) long.
√ Ensure that the person at the foot of the ladder faces the ladder with a hand
on each side rail and one foot resting on the bottom rung.
√ Attach hooks on top of ladder rails where ladder is to be used at a constant
height.
√ Do not rest a ladder on any rung. Only the side rails are designed for this
purpose.
√ Secure the base of ladder to prevent accidental movement. Securing a ladder
at the foot does not prevent a side slip at the top.
√ Use ladders equipped with non-slip feet. Otherwise nail a cleat to the floor or
anchor the feet or bottom of the side rails.
Extension Ladders:
√
√
√
√
√
√
Place ladders on a firm, level surface and ensure the footing is secure.
Erect extension ladders so that the upper section rests on (e.g. in front of)
the bottom section. This means the bottom section “faces” a wall or other
supporting surface (see figures below).
Place the ladder feet so that the horizontal distance between the feet and
the top support is ¼ of the working length of the ladder. The ladder will be
leaning at a 75o angle from the ground.
Raise and lower ladders from the ground. Ensure that locking ladder hooks
are secure before climbing.
Erect ladders so that a minimum of 1 m (3 ft) extends above a landing
platform. Tie the top at support points.
Where a ladder cannot be tied off at the top, station a person at the foot
to prevent it from slipping. This method is only effective for ladders up to
5 m (16 ft) long. The person at the foot of the ladder should face the
ladder with a hand on each side rail and with one foot resting on the
bottom rung.

√
√
√
√
Leave all tie-off devices in place until they must be removed before taking the ladder down.
Maintain the minimum overlap of sections as shown on a ladder label. Refer to safety regulations.
Do not use ladders near electrical wire.
Do not set up or take a ladder down when it is extended.
Do not overextend. Maintain minimum overlap of sections.
Do not climb higher than the fourth rung from the top of a ladder.
Do not use ladders on ice, snow or other slippery surfaces without securing ladders’ feet.
Do not extend top section of a ladder from above or by “bouncing” on a ladder.
Do not leave ladders unattended.
Setting up an extension ladder:
When setting up an extension
ladder, use the following
method to avoid straining
muscles or losing control of a
ladder. With ladders weighing
more than 25kg (55 lb), or
where conditions complicate the
task, have two persons set up a
ladder, step by step, as follows:
√ Lay a ladder on the ground close
to intended location.
√ Brace ladder base using helper’s
feet.
√ Grasp the top rung with both
hands, raise the top end over your
head and walk toward the base of
a ladder.
√ Grasp the centre of the rungs to
maintain stability.
√ Move the erect ladder to the
desired location. Lean it forward against the resting point.
One person can erect a short ladder, step by step as follows:
√ Place the bottom of the ladder firmly against the base of a building or stationary
object.
√ Lift the top of ladder, and pull upwards to raise a ladder to a vertical position.
√ Transfer a ladder to its required position when it is erect.
√ Keep a ladder upright and close to the body with a firm grip.
Step Ladders:
√
√
√
√
Use a step ladder that is about 1 m (3 ft) shorter than the highest point you
have to reach. This gives a wider, more stable base and place shelf at a
convenient working height.
Open the step ladder spreaders and shelf fully.
Check stability. Ensure that all ladder feet are on a firm, level and nonslippery surface.
Place a step ladder at right angles to the work, with either the front or back
of the steps facing the work.
Facility Services Safe Operating Procedure No. 0005
Safe Use of Ladders
22
√
√
Keep the stepladder close to the work.
Avoid pushing or pulling stepladders from the side. Repeated sideways movement can make ladders
wobbly since they are weaker or less stable in those directions.
√ Face the step ladder when climbing up or down. Keep your body centered between side rails. You
have climbed too high if your knees are above top of the step ladder or if you cannot maintain a
handhold on the ladder.
√ Maintain a firm grip. Use both hands when climbing.
√ Do not climb the back of a step ladder.
√ Do not push or pull stepladders sideways.
√ Do not use ladders in passageways, doorways, driveways or other locations where a person or
vehicle can hit it. Set up suitable barriers or lock doors shut.
√ Do not overreach. Move step ladder when needed.
√ Do not “shift” or “walk” a step ladder when standing on it.
√ Do not stand, climb, or sit on the stepladder top or pail shelf.
√ Do not overload. Step ladders are meant for one person.
√ Do not use a step ladder as a brace or as a support for a work platform or plank
√ Do not climb a step ladder that is leaning against a wall. Use a straight ladder instead.
√ Do not use stepladders on slippery surfaces.
√ Do not use step ladders on soft ground where one leg may sink farther into the ground than others.
√ Do not place step ladders on boxes, unstable bases or on scaffolds to gain additional height.
