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.

MEMORANDUM FOR:   Nicholas Di Archangel Acting Regional Administrator

ATTN:             E. Largent - Yamazen USA, Inc.

Subject:          Request for Interpretation

This is in reply to Mr. Largent's memo of August 4, 1976, subject as above, requesting an interpretation as to whether or not a piece of equipment would meet the intent of 1910.242(b).

Air guns with "air curtains" are acceptable as long as they meet the requirements of 1910.242(b) and Program Directive #100-1, dated February 14, 1972.

Since the above mentioned PD addresses this situation, the correspondence is being returned to your office for action. Your attention is also directed to the 1976 edition of the Best's Safety Directory on portable powered tools which reveals that this type of air gun is being presently marketed.

Barry J. White
Associate Assistant Secretary
