Mineral oil is the major chemical component of mineral oil hydraulic fluids. Mineral oil belongs to a larger class of chemicals called petroleum distillates. The Occupational Safety and Health Administration (OSHA) regulates petroleum distillate and mineral oil mist levels in workplace air. The occupational exposure limits for an 8-hour workday, 40-hour workweek are 2,000 milligrams per cubic meter (mg/m3) in air for petroleum distillates and 5 mg/m3 for mineral oil mists. The National Institute for Occupational Safety and Health (NIOSH) recommends an exposure limit of 350 mg/m3 of petroleum distillates for a 10-hour workday, 40-hour workweek. 

Oil accumulation in the lungs after long-term or high-level exposure to aerosols of polyalphaolefin may be a concern, based on observations of lipoid pneumonia in humans after prolonged intranasal application of mineral oil mists (Lushbaugh 1950) and the physical and chemical similarities between mineral oil and polyalphaolefins (i.e., both are composed predominately of aliphatic hydrocarbons). 

Regulations found for mineral oils include the OSHA occupational exposure limit for mineral oil mists of 5 mg/m3 (OSHA 1974). 

One case study was identified where a man who had been occupationally exposed to hexachloroethane was treated for a liver tumor (Selden et al. 1989). Exposure had occurred over a period of 6 years as a result of the presence of hexachloroethane in a degassing agent used during aluminum smelting. However, the hexachloroethane reacted at the 700 C use-temperature, releasing a gas that was 96% hexachlorobenzene with small amounts of other chlorinated compounds. Because there was occupational exposure to a mixture of chlorinated compounds rather than just hexachloroethane, it is highly unlikely that the tumor was the result of hexachloroethane exposure alone. Occupational exposure to mineral oil mists for 20 years was also part of the subject s employment history. 

Toxicology. Highly refined mineral oil mist is of low toxicity. 

A review of exposures to mineral oil mist averaging below 15 mg/m (but higher in some jobs) in several industries disclosed a striking lack of reported cases of illness related to these exposures. A smdy of oil mist exposures in machine shops, at mean concentrations of 3.7mg/m and maximum of llOmg/m showed no increase in respiratory symptoms or decrement in respiratory performance attributable to oil mist inhalation among men... 

Occupational exposures play an important role during adulthood. Often the exposures last for many years and exposure levels are much higher than those of the general population. Some of the common complex mixtures regulated in the workplace include coal tar pitch volatiles, mineral oil mist, petroleum distillates, and Stoddard solvent1 (Hearl 2005). There are numerous possible combinations of chemicals found at the workplace that is, most exposures are to chemical mixtures. 

Mineral oil mists have been given an lARC classification of 1 (sufficient evidence of carcinogenicity). The OSHA Permissible Exposure Limit (PEL) for mineral oil mist is 5 mg/m averaged over an 8-hour exposure period. NIOSH has concurred with this limit, and has established a recommended occupational exposure limit (REL-TWA) for mineral oil mists of 5 mg/m for a 10-hour work day, 40-hour work week, with a 10 mg/m Short Term Exposure Limit (STEL). 

OSHA regulates the benzene soluble fraction of coal tar pitch volatiles and mineral oil mist, which contain several ofthe PAH compounds. Employers of workers who are occupationally exposed must institute engineering controls and work practices to reduce and maintain employee exposure at or below permissible exposure limits (PEL). The employer must use engineering and work controls, if feasible, to reduce exposure to or below an 8-hour time-weighted average (TWA) of 0.2 mg/m for coal tar pitch volatiles and 5 mg/m for mineral oil mist. 

DISPOSAL AND STORAGE METHODS contaminated mineral oil can be disposed of by controlled ineineration alternatively, absorb in sand or other inert materials, and use for landfill at sites carefully chosen to avoid any risk of the oil causing contamination of water supplies store in a cool, dry location maintain adequate ventilation sources of ignition such as smoking and open flames are prohibited where Mineral Oil Mists are used, handled, or stored.
