Ignition sources smoking

Prohibit all sources of ignition, including smoking, within a store or within the separation distance (exclude motor vehicles other than fork-lift trucks and those for delivery/collection from open-air stores).

Fire precautions including control of ignition sources, e.g. smoking, maintenance activities, vehicular access (see Chapter 6) and limitation of combustible materials, e.g. packaging. 

Once ignited they produced considerable amounts of heat and smoke. Flame retarded flexible PU foams became available in 1954-55, i.e. within a few years of flexible PU foams becoming available in commercial quantities(22). These FR PU foams contained trichloroethyl phosphate or brominated phosphate esters and resisted ignition from small flame sources. Unfortunately they may burn when subjected to a larger ignition source or when covered by a flammable fabric and may then produce as much heat and more smoke than the standard grade of PU foam(3). This was identified by UK room tests in the early 1970 s and has been confirmed more recently by furniture calorimeter tests at the NBS(21). 

Fires in the workplace continue to be caused by matches, lighters, and carelessly discarded cigarettes and other smoking materials that ignite near combustible materials. Control of these potential ignition sources is essential for an effective fire prevention program. Facility management should consider... 

A furniture calorimeter consists of a weighing platform that is located on the floor of the laboratory, beneath a hood connected to an instrumented exhaust duct (see Figure 14.13). The object is placed on the platform and ignited with the specified ignition source. The products of combustion are collected in the hood and extracted through the exhaust duct. Measurements of oxygen concentration, flow rate, and light transmission in the exhaust duct are used to determine the heat release rate and smoke production rate from the object as a function of time. 

Open Flames. Open flames are an obvious ignition source (others are subtle, obscure). One must control smoking, welding, burning and other flame sources in areas of potential hydrogen leakage.
