Oxygen enrichment hazard

It is essential that persons be grounded in hazardous (classified) locations. For most (memical operations, the resistance to ground from the body should not exceed 100 megohms. A lower allowable resistance may be specified for locations where the presence of pri-maiy explosives, hydi ogen-air mixtures, oxygen-enriched mixtures, or certain solid-state devices requires faster charge dissipation. [Pg.2334]

There are many potential causes of explosions and fires at industrial sites handling hazardous substances (a) chemical reactions that produce explosion, fire, or heat (b) ignition of explosive or flammable chemicals (c) ignition of materials due to oxygen enrichment (d) agitation of shock- or friction-sensitive compounds and (e) sudden release of materials under pressure [21,29]. [Pg.67]

Flammable mist-vapor-air mixtures may occur as the foam on a flammable liquid collapses.28 Thus, when ignited, many foams can propagate flame. An additional hazard can arise from the production of foams by oxygen-enriched air at reduce pressures. Air confined over a liquid can become oxygen enriched as pressure is reduced because oxygen is more soluble than nitrogen in most liquids. Thus, the presence of foams on combustible liquids is a potential explosion hazard. [Pg.108]
