Dear Mr. Tynes:

Thank you for your letter of July 12, 1995 which requested a permanent variance from 29 CFR 1910.107(g)(5), in order to utilize n-butyl acetate as a solvent for the cleaning of electrostatic bells in your operation.

You indicated in your request for a variance that the paint spray used in your facility contains two solvents, MAK (methyl n-amine ketone) and toluene having flashpoints of 102 and 40 degrees F, respectively. In accordance with OSHA's standard, §1910.107(g)(5), you would be in compliance when you use any solvent for cleaning auxiliary equipment with a flash point of 40 degrees F or higher. Therefore, you do not need a variance to be in compliance, since you are using n-butyl acetate (flashpoint 83 degrees F).

Please note that in the future, if you should change your paint formulation, where the solvents in the paint may have flashpoints above 83 degrees F, then you would be required to select a solvent with a higher flashpoint than n-butyl acetate for the cleaning of auxiliary equipment.

Thank you for your inquiry. If you need further assistance, please call Alcmene Haloftis of my staff at 202-219-8031.

Sincerely,

John B. Miles, Jr., Director
Directorate of Compliance Programs
