Classification of butane
What is the compound classification of butane?
Butane, also known as N-butane belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms.
What class is butane fire?
Flammability: 4 (Extreme)
This degree includes flammable gases, flammable cryogenic materials, pyrophoric liquids, and Class IA flammable liquids.
What hazmat class is butane?
2.1
DOT#: UN 1011 ERG Guide #: 115 Hazard Class: 2.1 (Flammable gas) FLAMMABLE GAS Stop flow of gas or let fire burn itself out.
Why is butane a compound?
Butane is an organic compound that is made of hydrogens and carbons. It is a saturated hydrocarbon that is composed of a total of four carbons (as the prefix but- suggests) and ten hydrogen atoms. Its molecular formula is C4H10.
Is butane a flammable gas?
Highly flammable. BUTANE can explode when exposed to flame or when mixed with (nickel carbonyl + oxygen).
What are the four classes of fire?
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. Class D – fires involving metals.

What are the 3 elements of 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.
How many classes of fire are there?
There are four classes of fires: 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.
What is the classification of flammable liquids?
Flammable liquids are classified by NFPA as Class I, which are further sub- classified, based upon additional criteria that affect fire risk, as Class IA, Class IB and Class IC – these liquids have flash points below 100 ÂşF (37.8 ÂşC) or less.
What is a Category 2 flammable gas?
Category 2 means Gases, other than those of Category 1, which, at 20°C (68°F) and a standard pressure of 101.3 kPa (14.7 psi), have a flammable range while mixed in air. Table 2 shows some of the label elements for flammable gases.
What is a Class 3 hazardous material?
ORM-D or limited quantity only (dependent on flashpoint). Gasoline and items containing gasoline or gasoline fumes are always prohibited.
What are Class II and Class III liquids?
Class II liquids are combustible liquids that have a flash temperature point at or above 100 °F (37.8 °C) and below 140 °F (60 °C). Class IIIB liquids are combustible liquids that have a flash point at or above 200 °F (93 °C).
What is a Class 2 flammable liquid?
Category 2 Flammable Liquids
A Category 2 flammable liquid is any liquid with a closed-cup flash point below 73.4°F (23°C) AND with a boiling point above 95°F (35°C).
What is a Class 4 flammable liquid?
Category 4 shall include liquids having flashpoints above 140 °F (60 °C) and at or below 199.4 °F (93 °C).
What is a Class 2 liquid?
Class II: Liquids with a flash point at or above 100°F and below 140°F (60°C). Examples: No. 1, 2 and 3 fuel oils, kerosene, and hexyl alcohol.
What is a Class 1 gas?
Class I Locations A “Class I Location” is created by the presence of flammable gases or vapors in the air in sufficient quantities to be explosive or ignitable. When these materials are found in the atmosphere, a potential for explosion exists if an electrical or other source of ignition is present.
