10 STRATEGIES TO
CONTROL RISK
Strategy 1 Containment
 closed containers
 portable tanks
 storage tanks
 cabinets = limits/closed
Strategy 2 Control of Vapours
Strategy 3 Control of Quantity
Strategy 3 Control of Quantity
Equations:
Little q (actual quantity in litres)
Big Q (maximum quantity)
An Example: Assembly
qI/30 + qII/150 + qIIIA/600 < 1
Strategy 3 Control of Quantity
Assembly Maximum Quantities
Stored in building or single fire compartment
not less than 1 hr. fire resistance rating:
• Max. quantities of any single class of liquid:
30L Class I
150L Class II
600L Class IIIA
Strategy 3 Control of Quantity
Assembly Maximum Quantities
Two or more different liquid classes follow
equation:
qI/30 + qII/150 + qIIIA/600 < 1
Example One:
10/30 + 100/150 + 400/600
1.67
Example Two:
10/30 + 40/150 + 240/600
1.0
Strategy 3 Control of Quantity
Assembly Maximum Quantities
Quantities can be exceeded if kept in:
Code compliant cabinets not exceeding 500 L,
or
Code compliant room with no openings
directly into public portion of assembly
Strategy 4
Safe Handling Procedures
Strategy 5
Control Ignition Sources
 Smoking / Open Flames
 Hot works
 Static charge
 Sparks / Equipment maintenance
 Rag disposal
 Electrical Classification – Forklift trucks
Strategy 6
Primary Spill Management
Strategy 7
Secondary Spill Management
Strategy 8 Fire Separations
Strategy 9
Fire Suppression
 Sprinkler NFPA 30 “Flammable and
Combustible Liquids Code”
OR
 Automatic special fire suppression
system Article 6.8.1.1.
Strategy 10 Substitution
Gasoline stored in dwelling unit
