NO, NO, NO These are not ANSI rated or OSHA approved for any fall protection or confined space use and using them would be a danger to the worker and against the federal workers protection law. Only ANSI Z359.12 approved biners can be used. NFPA uses a similar rating but meets a different level for the heat.
