Slings--Steel Chain, Wire Rope,
and Metal Mesh
Self-Inspection Checklist

Guidelines: This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under the general industry standards 29 CFR 1910.184 and the construction standards 1926.251. It applies to slings used with other equipment to move material by lifting or hoisting. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or U.S. Environmental Protection Agency (EPA) standard, or with a nonregulatory recommendation. Definitions of terms in bold type are provided at the end of the checklist.

check mark symbol Questions marked with this symbol may require the help of an outside expert.

Numerous tables are included as part of 29 CFR 1910.184 and and 1926.251 that relate sling configuration, sling construction, sling diameter and maximum load capacity. These tables have not be included as part of this checklist. For additional information, consult the OSHA regulations.
