Hazards associated with stored energy
One of the hazards identified in our 4P FEEDS model, is
ENERGY. Hazards associated with energy are the highest
contributing factor to our Company incident statistic.
Energy is essential in our day-to-day operations (life)
however when become uncontrolled or exposed to may
cause serious injuries. In some cases, results in fatal
injuries.
Outcome of energy can sometimes be visible (kinetic) but
some energy may not be and still be present in a “rest” stage
(potential).
What is stored energy?
Stored energy, or potential energy, is the amount of energy
an object has due to its position in space. Since energy
cannot be created nor destroyed, it must be transferred to
move and be at rest. It’s the ability to change into another
kind of energy to do a work or cause a change.
How to protect ourselves?
Examples:
i.
A bicycle wheel that is pushed by the person’s legs
(paddling) is visible.
ii.
A light bulb that is not lit does not mean the wiring
that is connected is not LIVE. The electrical energy
is not visible in this case. It is the switch that
controls the flow of electricity.
iii.
A pipe that contains high pressure liquid will look
the same whether there are contents under
pressure or not inside it. However, when breaking
flanges, the pressurized liquid can burst in extreme
force which causes serious injuries to person
standing nearby.

Forms of Energy
Energy can be various forms such as Kinetic; Potential;
Mechanical, Chemical, Electrical, Magnetic, Radiant,
Nuclear, Ionization, Elastic, Sound, Gravity, Thermal. (Use
these terminologies when identifying energy related hazards)
e)
Identify all energy related hazards; STORED AND
VISIBLE; in your tasks before start work. Ensure
these are clearly identified in the Task Based Risk
Assessment (TBRA) or Job Safety Analysis (JSA).
Ensure to take measures in such manner that you
can never be exposed when this energy becomes
uncontrollable such as sudden release or when
directly exposed to.
Prior to work in any system that is energized or with
energy source, ensure system is de-pressurized
and supply is cut off.
Ensure the team owning the system has released
all stored energy e.g. a pipe line should be bled off
(released) and verified by the gauge to ascertain
that there is no stored energy.
Prior to work, to ensure the system is shut down
and measures are in place to prevent anyone from
inadvertently energizing or starting the system
through lock out tag out process. It is highly
recommended to place your own locks as well to
ensure that the system can never be start up
unless you remove your locks.
