Classification of flammable materials
What are the three types of flammable materials?
Flammable materials are easily ignited, causing fires. They can take the form of solid, liquid or gas. Common flammable materials found in workplaces include liquefied petroleum gas (LPG), paints, varnishes and lacquers.
What are Category 1/2 and 3 flammable liquids?
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)
What are Class 3 flammable liquids examples?
Class 3 Dangerous Goods Examples
Commonly transported class 3 dangerous goods include acetone, adhesives, paints, gasoline, perfume, ethanol, methanol and some pesticides with flammable solvents.

What is a Class 1 flammable?
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).
What is a Class 2 combustible liquid?
Class II liquids are combustible liquids that have a temperature flashpoint 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, methanol, and other solvents.
What hazard class is flammable?
Hazard Class 3 – Flammable Liquids
Flammable liquids have a “flash point” of 140°F or less. A flash point is the temperature when an ignition source near the liquid can ignite the vapors.
What is the symbol for flammable materials?
The flame symbol means the product may catch fire. Flammable products or their fumes may catch fire easily if near heat, flames or sparks.
What are the 6 classes of fires?
How many fire categories are there? There are six primary fire classes classified according to the igniting agent. Solids, gases, liquids, metals, kitchen oils, and electricity all come with different fire risks. Depending on the fire’s cause, some extinguishers are ideal, while others can cause more harm than good.
Which is a Class D combustible material?
Class D. Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals. Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase.
What are the examples of class A of fire?
Class A Fire
They are produced from common combustible materials including wood, paper, fabric, rubber, and plastic. Class A fires have relatively low ignition temperatures, and once the fuel or oxygen has been depleted, the fire will burn out. A garbage fire is one example of Class A fires.
What is considered a Class 3 flammable liquid?
Examples of Class 3 Flammable Liquids include acetaldehyde, petroleum ether, and ethyl chloride. Class 3 “Combustible” liquids are those with a flashpoint above 100 degrees and below 200 degrees Fahrenheit. Acetone, benzene, and methyl alcohol are all examples of Class 3 Combustible Liquids.
What class is a flammable liquid fire?
Class B
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
What is a 1C liquid?
CLASS 1C Flammable Liquids for Storage = Flashpoint at or above 73 F, boiling point below 100 F.
How many classes of hazardous materials are there?
nine hazard classes
Every hazardous material is assigned to one of nine hazard classes as defined in 49 CFR 172.101 and 173.
What are the examples of class A of fire?
Class A. Class A fires involve ordinary combustible materials, such as cloth, wood, paper, rubber, and many plastics. Extinguishers with an A rating are designed to extinguish fires involving these ordinary combustible materials.
Which is a Class D combustible material?
Class D. The Class D fire is defined as one that uses a combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. Note that there are also other metals with combustive properties you may encounter.
