Appropriate engineering controls and Environmental exposure controls
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits.
Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source,
preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Individual protection measures
Hygiene measures
No special protective clothing is normally required. Select protective clothing depending on industrial operations. Use
mechanical ventilation equipment that is explosion-proof.
Eye/face protection: Use chemical safety goggles.
Skin protection
Hand protection and Body protection: Wear impervious protective clothing, including boots, gloves, lab
coat, apron or coveralls, as appropriate, to prevent skin contact.
Other skin protection
Wash hands and other exposed areas with mild soap and water before eating or drinking.
Respiratory protection: No respiratory protection required under normal circumstances. Approved organic vapor
chemical cartridge or supplied air respirators should be worn when significant vapors are generated. Observe
respirator assigned protection factors (APFs) criteria cited in federal OSHA 1910.134. Self-contained breathing
apparatus should be used for firefighting.
Respirator Type(s) (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a
half face piece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure
limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier,
whichever is lowest. A full face piece particulate respirator (NIOSH type N100 filter) may be worn up to 50 times the
exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator
supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, Glycerin, etc.) are present, use a NIOSH
type R or P filter. For emergencies or instances where the exposure levels are not known, use a full face piece
positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in Oxygen-
deficient atmospheres.
