Selection and Use
Universal is a manufacturer size designation, not a guarantee that the harness fits every worker. Check chest, shoulder and leg adjustment before issuing it. Use the dorsal D-ring for the specified fall-arrest connection. Side D-rings serve work positioning; the front connection has application-specific limits in the instructions. Four rings do not establish approval for every rescue or confined-space system.
Standards and Safety
The manufacturer lists OSHA, ANSI and CSA compliance for this harness family. Confirm the supplied label and instructions for the applicable editions and capacity range. The 400 lb manufacturer maximum does not override a lower limit on a lanyard, lifeline or other component.
Employers must select compatible components, provide training and plan for prompt rescue. OSHA 1926.502 addresses construction fall-protection systems; OSHA 1910.140 applies to general-industry personal fall protection. These are employer requirements, not OSHA product approvals.
