United States Occupational Safety and Health

Formaldehyde has been rated as a possible carcinogen by the United States Occupational Safety and Health Act (OSHA) rules and should be handled with due caution. It is also a strong lacrymator and choking respiratory irritant. It irritates the skin, eyes, and mucous membranes [76]. Since it is used for tanning leather, it is obvious that fonnaldehyde has a high potential for reactions with proteins. Formaldehyde gas is flammable and most formalin solutions contain significant amounts of methanol, which is also volatile, toxic, and flammable.

P-methoxypropionitrile (Fajen, 1985a), furfural and aqueous cuprous ammonium acetate (United States Occupational Safety and Health Administration, 1990b). Stabilizers are commonly used to prevent formation of peroxides in air and polymerization. No information was available on these other exposures, or on exposures to chemicals other than butadiene that are produced in some facilities, such as butylenes, ethylene, propylene, polyethylene and polypropylene resins, methyl-tert-butyl ether and aromatic hydrocarbons (Fajen, 1985b,c).

The United States Occupational Safety and Health Administration (OSHA) (1996) has established 0.0001 mg/m as the permissible exposure limit for occupational exposures to l,2-dibromo-3-chloropropane in workplace air. 

Action Level A regulatory standard, especially used by the United States Occupational Safety and Health Administration (OSHA) for air contaminants, to indicate an unhealthy concentration of a substance. The US action level for arsenic in air is 5 mg m-3 averaged over an eight-hour period (29 Code of Federal Regulations 1910.1018). If an action level is exceeded, efforts must be made to protect individuals from exposure to the contaminant, reduce the concentration, and possibly monitor or treat exposed individuals. In general, action levels are 50 % of the permissible exposure limit (PEL) (compare with threshold limit value). 

In the United States, Occupational Safety and Health Administration lists butter yellow as a suspected human carcinogen. Human mutation data are also reported. 

United States Occupational Safety and Health Administration permissible exposure limit (Table Z-1) is 10 ppm (12mgm ).
