Class II liquids are combustible liquids that have a flash point at or above 100 °F (37.8 °C) and below 140 °F (60 °C). Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, and Stoddard solvent.
What is classified combustible?
Combustible liquids are classified as Class II and Class III, which are further sub-classified, based upon additional criteria that affect fire risk, as Class IIIA and Class IIIB – these liquids have flash points of 100 ºF (37.8 ºC) or more. Typical Class IA liquids include ethylene oxide, methyl chloride, and pentane.
What is considered a combustible liquid?
Combustible liquids have a flashpoint at or above 37.8°C (100°F) and below 93.3°C (200°F). Flammable and combustible liquids are present in almost every workplace. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and polishes may be flammable or combustible liquids.

What are the example of combustible?
Combustible material means a material that, in the form in which it is used and under the conditions anticipated, will ignite, burn, support combustion or release flammable vapors when subjected to fire or heat. Wood, paper, rubber, and plastics are examples of combustible materials.
What are the classification of combustible materials?
Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics. Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
Which is highly flammable liquid?
Also known as alcohol, ethyl alcohol or drinking alcohol, ethanol is a highly flammable liquid. Most alcoholic beverages contain a percentage of ethanol. It is a volatile and colorless substance with a distinct odor. Its flash point depends on the concentration of ethanol.
What is the most flammable liquid?
1) Chlorine Trifluoride is the most flammable gas Of all the dangerous chemical gases, chlorine trifluoride is known to be the most flammable.
Is diesel a Class 1 liquid?
Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids. Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, and Stoddard solvent.
Can you light a fire with diesel?
Diesel fuel can catch fire and is classified as a flammable liquid according to OSHA, because it has a flashpoint above 199.4 degrees Fahrenheit. The flashpoint of diesel is approximately 140 degrees Fahrenheit (60 Celsius). This means in most ambient temperatures it will not ignite.
Is diesel a C1?
Even though most diesel fuels are not classified as a flammable liquid, they are classified as a C1 combustible, and C1 combustibles are classified as dangerous substances by most state and territory regulations.
At what temp does diesel ignite?

At what flashpoint is considered flammable?
Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).
What is the fire point of diesel?

Is oil a combustible material?
Because engine oils have a flashpoint above 150 °C, they are classified as C2 combustibles and not Class 3 Flammable liquids.Is Oil Flammable? Class 3 – Flammable/Combustible Liquids Class 2.2 – Non-flammable, Non-toxic Gas Keep Apart Class 3 – Flammable/Combustible Liquids Compatible.
What does it mean if something is combustible?
A combustible material is a solid or liquid than can be easily ignited and burned. OSHA, DOT, and other federal regulations, apply specific technical definitions to this term. Combustible solids are those capable of igniting and burning. Wood and paper are examples of such materials.
What is a sentence for combustible?

Which gas is combustible?
Combustible gas is any gas that ignites when it is mixed with oxygen. Combustible gases are usually made up of hydrocarbons, hydrogen, carbon monoxide, or any combination of those gases. Examples of combustible gases include methane, butane, and propane.
What are the 5 fire classifications?
Fire is divided into five classes (A, B, C, D, and K) that are primarily based on the fuel that is burning. This classification system helps to assess hazards and determine the most effective type of extinguishing agent.
What are the 4 types of fires?
What are the fire safety rules? Class A – fires involving solid materials such as wood, paper or textiles. Class b – fires involving flammable liquids such as petrol, diesel or oils. Class c – fires involving gases.
What is a type of fire?
Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach. In fact, trying to fight a blaze with the wrong method might make the situation worse.
What liquids catch on fire?
Flammable and combustible liquids Besides gasoline and lighter fluid, things like rubbing alcohol, nail polish remover, hand sanitizer and wart remover can easily catch fire.
Is 40% alcohol flammable?
Is there something we should be drinking, instead? Vodka is most commonly 80 proof (40% alcohol by volume) and while it can catch fire, it is not considered to be flammable. This level of alcohol is too low to sustain a fire. Higher proof vodkas can be flammable.
Does thinner catch fire?
Paint thinner (mineral spirits) is a flammable liquid, as classified by OSHA. Since it can catch fire and has a flashpoint below 199.4 degrees Fahrenheit (93 Celsius) it is considered a flammable liquid. The flashpoint of paint thinner is around 104 degrees Fahrenheit. Care should be exercised with flammable liquids.
