Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...

Division 2.1: Flammable, Non-Toxic Gas Flammable gas means any material that: Is ignitable at 101.3 kPA (14.7 psia) when in a mixture of 13 percent or less by volume with air; or; Has a flammable range at 101.3 kPa with air of at least 12 percent regardless of the lower limit.
Flammable applies to combustible materials that ignite easily and thus are more dangerous and more highly regulated. Less easily ignited less-vigorously burning materials are combustible . For example, in the United States flammable liquids , by definition, have a flash point below 100 °F (38 °C)—where combustible liquids have a flash point ...
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
Flammable gases – Gases which at 20 °C and a standard pressure of 101.3 kPa: are ignitable when in a mixture of 13 percent or less by volume with air; or; have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. Alternative sign. Division 2.1 Non-flammable non-toxic gases – Gases which:
Lighter fluid or lighter fuel may refer to: . Butane, a highly flammable, colourless, easily liquefied gas used in gas-type lighters and butane torches; Naphtha, a volatile flammable liquid hydrocarbon mixture used in wick-type lighters and burners
