How do you know if a liquid is flammable?
Flammability is determined by the flash point of a material. Flash point is the minimum temperature at which a liquid forms a vapor above its surface in sufficient concentration that it can be ignited. Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier.
How can you classify flammable liquids based on their flash points?
Categorization
- Category I flammable liquids are those with boiling points ≤ 95 °F (35 °C) and flash points < 73 °F (23 °C)
- Category II flammable liquids are those with boiling points > 95 °F and flash points < 73 °F.
- Category III flammable liquids are those with flash points > 73 °F and ≤ 140 °F (60 °C)
How is a flammable liquid defined?
Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C). Flammable liquids are divided into four categories as follows: 1. Category 1 shall include liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point at or below 95 °F (35 °C). 2.
What precautionary measure would you cite about flammable materials?
Eliminate ignition sources (sparks, smoking, flames, hot surfaces) when working with flammable and combustible liquids. Use the smallest amount of flammable liquid necessary in the work area. Keep storage areas cool and dry. Store flammable and combustible liquids away from incompatible materials (e.g., oxidizers).
What are examples of flammable liquids?
Flammable: A liquid with a flash point under 100°F is considered flammable. Examples: gasoline, acetone, toluene, diethyl ether, alcohols.
What liquid causes fire?
Flammable and combustible liquids There’s likely a long list of flammable liquids in your home. Besides gasoline and lighter fluid, things like rubbing alcohol, nail polish remover, hand sanitizer and wart remover can easily catch fire.
What liquid makes a fire bigger?
Many accelerants are hydrocarbon-based fuels, sometimes referred to as petroleum distillates: gasoline, diesel fuel, kerosene, turpentine, butane, and various other flammable solvents. These accelerants are also known as ignitable liquids.
What 3 things make a fire?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
What liquids catch on fire?
When protecting your home against a fire, keep in mind these common household item and liquid flammables:
- Rubbing Alcohol.
- Nail polish and nail polish remover.
- Linseed oil.
- Aerosol cans.
- Non-dairy creamer.
- Gasoline, turpentine, and paint thinner.
- Hand sanitizer.
- Flour.
What is the flash point of a flammable liquid?
Under the Workplace Hazardous Materials Information System (WHMIS) 1988, flammable liquids have a flash point below 37.8°C (100°F). Combustible liquids have a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F).
Where can flammable and combustible liquids be found?
Most flammable and combustible liquids flow easily. A small spill can cover a large area of workbench or floor. Burning liquids can flow under doors, down stairs and even into neighbouring buildings, spreading fire widely. Materials like wood, cardboard and cloth can easily absorb flammable and combustible liquids.
How many gallons of flammable liquids can be stored in one cabinet?
Cabinets shall be labeled in conspicuous lettering, “Flammable-Keep Away from Open Flames.” 1926.152 (b) (3) Not more than 60 gallons of Category 1, 2 and/or 3 flammable liquids or 120 gallons of Category 4 flammable liquids shall be stored in any one storage cabinet. Not more than three such cabinets may be located in a single storage area.
Can a Category 2 flammable liquid be vented?
Tanks and pressure vessels storing Category 2 flammable liquids and Category 3 flammable liquids with a flashpoint below 100 °F (37.8 °C) shall be equipped with venting devices which shall be normally closed except when venting under pressure or vacuum conditions, or with approved flame arresters.
