Basic procedures for handling flammable liquids.
This regulation prescribes the basic procedures concerning the storage, dispensing and use of flammable liquids. This procedure is not all inclusive; therefore, prudent judgment must be employed for those specific applications not otherwise identified.
The vapors of a flammable liquid often present the most serious hazard. The vapors can easily ignite or explode. Flammable liquid vapors are heavier than air and may settle in low spots, or move a significant distance from the liquid itself. If there is a long vapor trail, and one end gets lit through a spark or something, the fire can travel ..
Storage of Flammable Liquids:
Design, construction and capacity of containers.
Only approved containers shall be used.
Design, construction and capacity of storage cabinets.
Not more than 120 gallons of Class I, Class II, and Class III Liquids may be stored in an approved storage cabinet. Of this total, not more than 60 gallons may be Class I or Class II Liquids. When approved, no more than three such cabinets may be located in a single fire area.
All approved cabinets shall be labeled in conspicuous lettering, FLAMMABLE - KEEP FIRE AWAY.

Fires caused by flammable liquids
A Class B fire is classified as a fire started by flammable or combustible liquids such as gasoline, kerosene, paint, paint thinners and propane. You can prevent this class of fire by not refueling gasoline-powered equipment in a confined space, especially in the presence of an open flame such as a furnace or water heater. Don t refuel gasoline-powered equipment while it s hot. Keep flammable liquids stored in tightly closed, self closing, and spill-proof containers. Store flammable liquids away from spark-producing sources. Use flammable liquids only in well-ventilated areas. You can exting ..
Once in the stairwell, proceed down to the first floor. Never go up.
Once outside the building, report to a predetermined area so that a head count can be taken.
What to do if you are trapped in a burning building
If you re trying to escape a fire, never open a closed door without feeling it first. Use the back of your hand to prevent burning your palm. If the door is hot, try another exit. If none exists, seal the cracks around the doors and vents with anything available.
If in a room, use wet towels to seal the space under the door and prevent the entry of smoke. Cracks around the door can be sealed with masking tape if necessary.
If trapped, look for a n ..
Flammable Liquid Safety
Flammable liquids are used in many different ways. They present unique hazards to the people that use them. Flammable liquids can cause a fire or explosion, and like many other substances, they can also cause serious health effects from overexposure. This article takes a look at flammable liquid hazards and discusses ways to use them safely.
Flammable liquids are liquids with a flash point of less than 100 degrees Fahrenheit. The flash point is the lowest temperature at which a liquid gives off enough vapor to form a flammable mixture with air. On the NFPA diamond label, a fire hazard ra ..

Flammable Liquids
This guideline is designed to help you store flammable liquids safely. To store flammable liquids safely, or if you are designing a flammable liquids storage area, consider the following:
design and construction of storage containers
the class of flammable liquids
the quantity to be stored
your storage location
how it will be used
ventilation
fire protection
control of ignition sources
Storage Containers
Containers of not more than 1 liter capacity used for flammable liquids (5 liters for combustible liquids) are exempt from the above requirement. Ensur ..
If you are storing Class 1B, Class 1C and combustible liquids in the same individual storage area, the total quantity of all classes of liquid storage must not exceed 2,500 liters (which is the maximum permitted for the liquid with the lowest limit).
Fire-separated Room in the Workplace
A room in which flammable liquids, in sealed containers, are stored must:
Be separated from the rest of the building by partitions which have:
- a fire resistance rating of at least one hour based on quantity stored
- self-closing doors, hinged to swing outwardly on their vertical axes
Be equipped with:
- a drain connected to a dry sump or holding tank
- liquid-tight seals between interior walls and floor, and a liquid tight ramped sill at any door opening which is not in an exterior wall
Be designed to prevent spills from flowing outside the s ..
Outdoor Storage
If you are storing flammable or combustible liquids outdoors, ensure that:
containers are piled away from buildings (especially building exits), employees, and
ignition sources
there are physical separations between areas, storage piles, buildings and property lines to act as a barrier against the spread of fire
the total quantity of flammable liquid per pile does not exceed 5,000 liters for Class 1A
flammable, or 15,000 liters for Class 1B or 1C flammable
the total quantity of combustible liquid per pile does not exceed 35,000 liters for Class II, and 85,000 liters for Class IIIA li ..
What are flammable and combustible liquids?
Flammable and combustible liquids are liquids that can burn. They are classified, or grouped as either flammable or combustible, by their flashpoints. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily, usually at normal working temperatures. Combustible liquids have the ability to burn at temperatures that are usually above working temperatures.
There are several specific technical criteria and test methods for identifying flammable and combustible liquids. Under the Workplace Hazardous Materials Information System (WHMIS), flammable liquids have a flashpo ..
Auto-ignition temperatures, however, are intended as guides, not as fine lines between safe and unsafe. Use all precautions necessary.
At normal room temperatures, flammable liquids can give off enough vapors to form burnable mixtures with air. As a result, they can be a serious fire hazard. Flammable liquid fires burn very fast. They also give off a lot of heat and often clouds of thick, black, toxic smoke.
Combustible liquids at temperatures above their flashpoint also release enough vapor to form burnable mixtures with air. Hot combustible liquids can be as serious a fire hazard as flammable liquids.
Spray mists of flammable and combustible liquids in air may burn at any temperature if an ignition source is prese ..
