Dear Mr. VonEschen:
This is in response to your letter of April 29, 1977, to the Occupational Safety and Health Administration (OSHA), Denver Regional Administrator, Curtis Foster, concerning a safety sleeve your company has designed for guarding projecting shaft ends, and a request for a clarification of the term "safety sleeve" as used in 29 CFR 1910.219(c)(4)(i). Your letter was forwarded to this office for reply.
The term "safety sleeve" means a smooth-type cover of durable material used to prevent an accident from exposure to the hazard created by the rotating motion of the shafts, keys, set screws, and other projections.
The proposed shield for projecting shaft ends comes within the category of a safety sleeve. If the proposed safety sleeve functions as described, the protective sleeve rotates with the shaft and when externally contacted the outer sleeve becomes stationary thus isolating the individual from the rotating shaft; it would meet the intent of 29 CFR 1910.219(c)(4)(i).
Thank you for your concern and continuing interest in occupational safety and health.
Richard P. Wilson
Deputy Director, Federal Compliance
