Description |
Colorless, oily liquid aerosol dispersed in air. [Note: Has an odor like burned lubricating oil.]; [NIOSH] |
Sources/Uses |
There are 3 classes of metalworking fluids (MWF). Mineral oil mist is in the first class of straight oils without added water. The other 2 classes are soluble/semi-synthetic and synthetic with no added oil. MWFs are described as either "neat" as supplied by the vendor or "in-use." In-use MWFs contain biocides as well as metal and microbial contaminants not present in the neat products. [Rosenstock, p. 1043-54] |
Comments |
Since the 1960s, the use of oil-based metalworking fluids (MWFs) has declined with increasing substitution of emulsified and synthetic fluids. [Burgess, p. 147] Asthma reported in toolsetters; [Malo] The cause of "Metalworking Fluids HP," one type of hypersensitivity pneumonitis, is microbially contaminated, water-based metalworking fluids used by machinists, and the antigens are probably Mycobacteria chelonae or fungi. "In conclusion, the large number of case reports, the cancer incidence study, and the case-control study suggest that primarily straight MWF exposure is associated with an increased risk for skin and scrotal cancer." [Occupational Exposure to Metalworking Fluids, NIOSH] Preservatives used in MWFs include: Dowicil 75, Tris Nitro, Grotan BK, Triadine-10, Onyxide-200, Vancide TH, Myacide BT. [Marks, p. 89] See the Disease "Metalworking fluids HP" and the Process "Metal Machining." |

Excerpts from Documentation for IDLHs |
Basis for revised IDLH: The available toxicological data contain no evidence that an acute exposure to a high concentration of oil mist (mineral) would impede escape or cause any irreversible health effects within 30 minutes. |
Lethal Concentration |
LC50 (rats) = 2,062 ppm/4h |
Explanatory Notes |
For metalworking fluid aerosols, NIOSH REL = 0.5 (Total particulate mass) or 0.4 (Thoracic particulate mass); [p. 1, Pub # 98-102] See 2008 Notice of Intended Changes for "Mineral oil." [ACGIH]; Flash point = 135 deg C; |
