Gases flammability limits

NATURAL GAS Flammable gas consisting essentially of methane with very minor proportions of other gases. Flammable limits approximately 5-15%. Odourized for commercial distribution within the UK. 

Fire Hazards - Flash Point Flammable gas Flammable Limits in Air (%) 5.0 - 15.0 Fire Extinguishing Agents Stop flow of gas Fire Extinguishing Agents Not To Be Used Water Special Hazards (f Combustion Products None Behavior in Fire Not pertinent Ignition Temperature (deg. F) 1004 Electrical Hazard Class I, Group D Burning Rate 12.5 mm/min.

F) 850 Electrical Hazard Data not available Burning Rate No data. 

When chlorine is reacted with a fuel on a catalyst bed, maloperation will result in catalyst burn- out and/or gas phase explosion before or after the catalyst. Here the determination of the fuel gas flammable limits in chlorine are of interest if the feed gas is not in the flammable range in normal process conditions. 

ETHYLENE FLUORIDE (75-37-6) Flammable gas (flammability limits 3.7-18% by volume in air). Violent reaction with strong oxidizers, barium, sodium, and potassium. Incompatible with powdered aluminum, liquid oxygen, potassium,. sodium. May form explosive compounds with divalent light metals and metallic azides. Attacks some metals in the presence of moisture. Undergoes thermal decomposition when exposed to flame or red-hot surfaces. Flow or agitation of substance may generate electrostatic charges due to low conductivity.
