Here’s a list of the top ten enquiries sent by e-mail to OSHA about its regulations. The agency keeps tabs both by e-mail and phone enquiry, so a notation in parentheses shows the phone rank and regulation link:

  1. Powered industrial trucks (1910.178, #3)
  2. Sanitation (1910.141, #4)
  3. Hazard communication (1910.1200, #2)
  4. Bloodborne pathogens (1910.1030, #1)
  5. Personal protective equipment, general requirements (1910.132, #5)
  6. Medical services and first aid (1910.151, #6)
  7. Ergonomics (no OSHA standard, not on phone list)
  8. Electrical, general requirements (1910.303, not on phone list)
  9. Respiratory protection (1910.134, #8)
  10. Air contaminants (1910.1000, #7).

Stolen shamelessly (but with attribution) from Safety News Alert, which also notes:

“The two questions in the top-10 list of questions received by phone that aren’t on the e-mail list are about indoor air quality (no OSHA standard) and permit-required confined spaces (1910.146).”
