Mr. J.P. Isherwood Dear Mr. Isherwood: This is in response to your recent letter addressed to Secretary of Labor Marshall, regarding twist lock receptacles and attachment plugs. Please accept our apology for the delay in response. In answer to your first question, the OSHA standards do not state anywhere that twist lock receptacles must be employed as the only means to come into compliance. In answer to your second question, "rough use" is not explicitly defined in the standards. However, an attachment plug to endure "rough use" would be, for example, and industrial-type or "Hospital Grade" plug rather that the usual domestic-type plug as described, for instance, in the Best's Safety Directory 1976, pages 664-665 (copy enclosed). Should you desire further clarification, you may find it convenient to contact the California Department of Industrial Relations, which is enforcing the occupational safety and health standards in California. The address and telephoner number of that office follow: Donald Vial, Director Department of Industrial Relations 455 Golden Gate Avenue San Francisco, California 94102 Telephone: 916-445-1935Sincerely, John K. Barto, Chief Division of Occupational Safety Programming Enclosure |
