Finely divided aluminium powder or dust forms highly explosive dispersions in air [1], and all aspects of prevention of aluminium dust explosions are covered in 2 recent US National Fire Codes [2], The effects on ignition properties of impurities introduced by recycled metal used to prepare dust were studied [3], Pyrophoricity is eliminated by surface coating aluminium powder with polystyrene [4], Explosion hazards involved in arc and flame spraying of the powder are analysed and discussed [5], and the effect of surface oxide layers on flammability was studied [6], The causes of a severe explosion in 1983 in a plant producing fine aluminium powder are analysed, and improvements in safety practices discussed... 

All aspects of prevention of magnesium (and aluminium) dust explosions in storage, handling or processing operations are covered in two recent US National Fire Codes [1]. Effects of various parameters on ignition of magnesium powders were studied [2], Maximum explosion pressures of 7.9 bar, with maximum rate of rise of 884 bar/s have been recorded [3],... 

The recent US National Fire Code covers all aspects of equipment, installation and safe operational practices necessary for bulk oxygen storage at consumer sites. 

The new US National Fire Code covers the precautions necessary to prevent fires or explosions during crushing of the solid, or during handling of the molten element. 

National Fire Code The National Fire Code consists of approximately 300 codes and standards as published by the National Fire Protection Association (NFPA). These codes address the practices to reduce the burden of fire on the quality of life by advocating scientifically based consensus codes and standards, research and education for fire and related safety issues. The most widely applied codes are ...

Each year, statistics on causes and occupancies of fires and deaths resulting from fire are compiled and published. NFPA sponsors seminars on the Life Safety Codes, National Electrical Code, industrial fire protection, hazardous materials, transportation emergencies, and other related topics. NFPA also conducts research programs on delivery systems for public fire protection, arson, residential fire sprinkler systems, and other subjects. NFPA publications include National Fire Codes Annual, Fire Protection Handbook, Fire Journal and Fire Technology. 

The quite loud explosions (either immediate or delayed) which occur when LNG (containing usually high proportions of heavier materials) is spilled onto water are non-combustive and harmless [1]. Superheating and shock-wave phenomena are involved [2]. There is a similar effect when LNG of normal composition (90% methane) is spilled on to some CsCg hydrocarbons or methanol, acetone or 2-buta-none [3]. A US National Fire Code covers site selection, design, construction and fire prevention aspects of LNG installations [4].
