ASSP - ANSI Z359.11
Safety Requirements for Full Body Harnesses
|Publication Date:||1 January 2021|
This standard establishes requirements for the performance, design, marking, qualification, instruction, training, test methods, inspection, use, maintenance and removal from service of full body harnesses (FBH). FBHs are used for fall arrest, positioning, travel restraint, suspension and/or rescue applications for users within the capacity range of 130 to 310 pounds (59 to 140kg).
NOTE: See Figures 1a through 1e for five basic examples of full body harnesses covered under this standard.
At the time of this standard's development, insufficient scientific data existed regarding the human response related to use of FBHs outside of the weight capacity defined. While there are methods that can demonstrate the efficacy of the FBH's load bearing components, such as the webbing, sewn webbing terminations, buckles and other connectors, the ability of the human body is more nuanced. Therefore, the committee believes more research is needed to determine an individual's physical attributes needed to withstand an impact and suspension for a period of time to be determined before a rescue is completed.
