Key Questions
The following key questions are answered in this module:
What are common flammable and combustible liquids present in most workplaces?
Fuels and common products such as solvents, thinners, cleaners, adhesives, and paints may be flammable or combustible.
What is the difference between flammable and combustible liquids?
Flammable and combustible liquids are liquids that can burn. The main difference between the two is that flammable liquids can catch fire and burn easily at normal working temperatures, whereas combustible liquids require higher than normal temperatures to ignite. The technical classification of these liquids is based on their flash points.
How should work environments plan on controlling any hazards involving flammable and combustible liquids?
The plan should include at least these components: identification of flammable and combustible liquids, identification and control of ignition sources, proper storage of the liquids, ventilation, fire control, and safe handling of the liquids.
What are some potential ignition sources that could lead to fires or explosions?
Ignition sources include: sparks and open flames, including smoking, welding, and cutting; hot surfaces, sources of radiant heat, and heat caused by friction; chemical reactions that produce heat; and electrical or mechanical sparks, including lightning and static electricity.
How should workers store flammable and combustible liquids?
Always store flammable and combustible liquids in closed metal containers or safety cans when they are not use. This prevents fumes from mixing with the air. Safety cans for storage and transfer must: be approved for this use, be constructed of metal, hold no more than 5 gallons, and have a spring-closing lid, a spout cover, and a flame arrestor screen.
