Ensure all other components in your fall protection system are also rated appropriately for your application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which D-ring should be used for fall arrest?\u003c\/strong\u003e\u003cbr\u003eA: The fall arrest subsystem (lanyard, SRL, energy absorber) must be connected only to the dorsal D-ring located on the back between the shoulder blades. Belt-mounted or ventral D-rings are designated for work positioning or restraint systems only and must never be used for fall arrest.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What should I do if the harness has been involved in a fall?\u003c\/strong\u003e\u003cbr\u003eA: Remove the harness from service immediately after any fall arrest event. The fall indicators will show visible activation. Contact Palmer Safety or your distributor regarding replacement — do not return the harness to service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What standards does this harness conform to?\u003c\/strong\u003e\u003cbr\u003eA: The Mako Series Full Body Harness meets or exceeds ANSI Z359.11-2021 and A10.32-2012.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use snap hooks to connect to the web loops on the harness?\u003c\/strong\u003e\u003cbr\u003eA: No. Do not use snap hooks to connect to web loops. Use a self-locking carabiner to connect to a web loop, and ensure the carabiner cannot cross-gate load. Some lanyards are designed to choke onto a web loop — refer to the subsystem manufacturer's instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should the harness be inspected?\u003c\/strong\u003e\u003cbr\u003eA: The harness must be inspected before each use by the authorized user. In addition, a qualified person must inspect all equipment on a regular basis as part of an ongoing fall protection program.\u003c\/p\u003e","brand":"Palmer Safety","offers":[{"title":"Small","offer_id":48923162542254,"sku":"H212100031.SM","price":72.5,"currency_code":"USD","in_stock":true},{"title":"Universal","offer_id":48923162575022,"sku":"H212100031","price":72.5,"currency_code":"USD","in_stock":true},{"title":"2XL","offer_id":48923162607790,"sku":"H212100031.2XL","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0551\/8396\/6382\/files\/H212100031-New-Front.jpg?v=1787153065","url":"https:\/\/www.diamondtoolstore.com\/products\/mako-series-harness-5pt-tongue-and-buckle-leg-straps-back-d-ring","provider":"Diamond Tool Store","version":"1.0","type":"link"}
