Potential Hazard
  • Potential chemical exposures to maintenance personnel working on reaction chambers, pumps, and other associated equipment that may contain reaction-product residues.
Possible Solutions
  • Identify chemical hazards and perform appropriate exposure evaluations.
    • Perform exposure measurements for the chemicals used.
    • 29 CFR 1910.1000 Table Z-1 contains permissible exposure limits for various chemicals.
  • Address all dermal exposures.
  • Provide appropriate ventilation to reduce chemical concentration levels in the air.
  • Provide PPE [29 CFR 1910 Subpart I] as appropriate to prevent eye and skin contact.
  • Use respiratory protection [29 CFR 1910.134] when necessary to further reduce exposure and protect employees.
  • Implement appropriate maintenance procedures and work practices designed to prevent or minimize exposure. Provide proper training for maintenance and other affected personnel.
  • Install emergency facilities to provide immediate treatment in the event of an accidental exposure to corrosive materials. According to 29 CFR 1910.151, provide suitable facilities for quick drenching or flushing of the eyes and body for immediate emergency use whenever the eyes or body may be exposed to corrosive materials.
Additional Information
  • Occupational Health Guidelines for Chemical Hazards. US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 81-123, (1981, January). Provides a table of contents of guidelines for many hazardous chemicals. The files provide technical chemical information, including chemical and physical properties, health effects, exposure limits, and recommendations for medical monitoring, personal protective equipment (PPE), and control procedures.
