OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.
Dear Mr. Cory:
This is in response to your letter requesting clarification of standards approving lighting fixtures in spray booths.
OSHA may not approve products by law. It merely sets standards which must be met by industries having exposures involving the safety and health of employees.
In the case of spray booth lighting the OSHA standard, 1910.107(b)(10) and (c)(7), states that illumination shall have fixed lighting units outside of the spray booth permitting light to enter through transparent panels. Such fixtures shall be totally enclosed if they are within 20 feet of the spray booth. In addition, compliance with the National Electrical Code NFPA 70-1971 is also mandatory.
We have mailed, under separate cover, several OSHA brochures including the Federal Register noted above. Please feel free to contact us if there are further questions about OSHA.
Very truly yours,
John J. Kearney
Associate Assistant Regional Director
for Technical Support/OSH
