Which standard covers all harness construction and testing?

The standard that covers all harness construction and testing is NFPA 1983. This standard specifically addresses the design, performance, testing, and certification of life safety ropes, harnesses, and other associated equipment used in technical rescue operations. It provides stringent regulations and guidelines to ensure that harnesses meet safety requirements and perform adequately in emergency situations. The focus on harness construction includes aspects such as materials, stitching, strength testing, and user compatibility, all essential for the protection of individuals during rescue operations.

While other standards mentioned may pertain to specific aspects of equipment or performance, none comprehensively covers the overall construction and testing of harnesses in the way NFPA 1983 does. This makes NFPA 1983 the go-to standard for ensuring that harnesses are safe and reliable for rescue operations.
