Flammable liquid Explosive range

Carbon disulfide is an extremely flammable liquid, the closed cup flash point being -22°F (-30°C). Its autoignition temperature is 90°C (194°F). Its vapors form explosive mixtures with air, within a wide range of 1.3 to 50.0% by volume in air. Reactions with certain substances can progress to explosive violence. They include finely divided metals, alkali metals, azides, fulminates, and nitrogen dioxide. 

Where this value is known it is an excellent measure of the relative hazard of a flammable liquid. Unfortunately, it is available in only a few instances Susceptibility to Spontaneous Heating. Many materials combine with atmospheric oxygen at ordinary temperatures and liberate heat. If the heat is evolved faster than it is dissipated due to poor housekeeping, a fire can start, particularly in the presence of easily ignited waste, etc. [ Factory Mutual Modified Mackey Method, Industrial and Engineering Chemistry (March 1927)] Explosive Range or Flammability Limits. 

Ethylene oxide vapor is extremely flammable at concentrations ranging from 3% to 100% and subject to explosive decomposition. Although liquid ethylene oxide is relatively stable, contact with acids, bases, or heat, particularly in the presence of metal chlorides and oxides, can lead to a violent polymerization. 

Tetrahydrofuran is a flammable liquid with a flash point of 6°E and explosive limits ranging from 2% (lower) to 11.8 % (upper). It is incompatible with strong oxidizers and lithium-aluminum alloys. Peroxides may accumulate upon prolonged storage in the air. 

Flammable liquid flash point (open cup) 29°C (84°F) autoignition temperature 371°C (700°F). 1-Propanol forms explosive mixtures with air within the range of 2-14 by volume in air. Violent reactions may occur when it is mixed with strong oxidizing substances. 

Flammable liquid flash point (closed cup) 21°C (70°F) vapor pressure 17 torr at 25°C (77°F) vapor density 2.0 (air=l) the vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back autoignition temperature 378°C (713°F) forms explosive mixtures with air in the range 2.5-18.0% by volume in air. It is susceptible to forming peroxides on prolonged exposure to air. 

Flammable liquid, flash point 24.4°C (76°F) antoignition temperatnre 405°C (761°F) vapor forms explosive mixtures with air within the range 1.7-9.8% by volume in air at 100°C (212°F). It may react violently with strong oxidizing substances.
