Exceptions to the preceding requirements would apply where explosionproof equipment is needed building ceiling heights are such that the standard 3.7-m (12-ft) lift is all that wih ever be needed and loads will never exceed 1 to 1.5 tons. Safety requirements for lift trucks are mandated by OSHA, by NIOSH (National Institute of Occupational Safety and Health), by State Depts. of Labor, and often by individual company standards. Among these requirements are backup-movement signals, seat belts, overhead framework for pro-...

Inhalation Exposure Levels. For setting acceptable maximum inhalation exposure levels, we usually use the lowest threshold limit values of those set by Federal OSHA (Occupational Safety and Health Administration), California OSHA, or the ACGIH (American Conference of Governmental Industrial Hygienists). Sometimes, as with ethylene dibromide, we accept a NIOSH (National Institute of Occupational Safety and Health) recommended standard which is lower than the three standard-setting entities previously mentioned. In other cases, when a standard has not been set by any of these groups, we set one ourselves based on available inhalation toxicity information. 

NIOSH National Institute of Occupational Safety and Health. U.S. Congress set up this institute in 1970 to play a key role in the protection of the health of occupational workers. The agency conducts occupational health research, inspects industries and manufacturing plants at the request of the employers and workers, and collects data for their own studies, to recommend standards for safe exposure to hazardous substances.
