Flammable Gas

Gases Flammable gases are usually very easily ignited if mixed with air. Flammable gases are often stored under pressure, in some cases as a hquid. Even small leaks of a liquefied flammable gas can form relatively large quantities of gas, which is ready for combustion. 

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. 

A methane leak in a closed room is assumed to mix uniformly with air in the room. The room is (4 x 4 x 2.5)m high. Take the air density as 1.1 kg/m3 with an average molecular weight of 29 g/g mole. How many grams of methane must be added to make the room gases flammable The lower and upper flammability limits of methane are 5 and 15 % by volume respectively.

The reader should be aware that all my experiences were within a major chemical plant with about 2 billion replacement cost, 1,650 employees, and over 250 acres of chemical plant. There are toxic gases, flammable gases, flashing flammable liquids, combustible liquids, and caustic materials, but there were no significant problems with combustible dusts and no significant problems with static electricity.

Water Reactive Material a substance that will spontaneously react with water to release toxic gases, flammable gases, or amounts of heat that could become significant (e.g., resulting in splattering, pressure-volume explosions). It includes those materials that can form explosive mixtures with water.

As a construction worker, you may be involved in transporting hazardous materials. The term hazardous materials (hazmat) is defined as materials capable of posing an imreasonable risk to health, safety, and property, when transported in commerce. Hazmat includes, but is not limited to, explosives, gases, flammable or combustible hqmds, flammable sohds, oxidizers or organic peroxides, poisons, radioactive materials, and corrosives. 

Note 2 Flammable aerosols do not fall additionally within the scope of flammable gases, flammable liquids, or flammable solids. 

Welding or cutting must not be done near exposed flammable liquids or gases. Flammable dust in the work area should be removed or shielded to prevent ignition. 

There are nine classes of dangerous goods, with divisions of some classes. The classes are explosive flammable and non-flammable non-toxic gases flammable liquids flammable solids and spontaneously combustible materials oxidizing substances and organic peroxides toxic and infectious substances radioactive and fissile materials corrosive substances and miscellaneous.

Gases - flammable gases include LPG (liquefied petroleum gas in cylinders, usually butane or propane), acetylene (used for welding) and hydrogen. An explosion can occur if the air/ gas mixture is within the explosive range.
