What the Product Page Documents
Published · Last updated

The MSA Suspension Trauma Safety Step is a harness-mounted step — a worker suspended after a fall arrest presses down on it to shift weight off the leg straps, helping maintain blood flow while awaiting rescue, without unfolding a pair of loops.
Shoppers researching suspension trauma relief options who want a step-style mechanism rather than strap loops land on this MSA device.

It's ranked in our suspension trauma straps guide, forms part of the rescue planning covered in the fall protection equipment guide, and pairs with a harness from the full body harness collection, ranked in our best safety harness guide, including MSA's own Workman full body harness and Gravity utility harness.

How We Review
Reviews in this family are grounded in the ABC system — Anchor, Body harness, Connector — and ANSI Z359-series ratings as stated on each listing. We restate only what the listing or product page documents; clearances, ratings, and compatibility always verify against the label and manufacturer instructions before use. Ratings reflect documented spec, configuration, and value — the basis is stated, not invented testing.

Editorial Standards
Claims are drawn from listing data and published standards. WC Safety does not invent specifications or test results. Report errors to safetynw2012@gmail.com.
Primary sources for this page
The wording behind this page sits in OSHA 29 CFR 1910.132, NIOSH Personal Protective Equipment.
Why trust this page?
Why trust this page? Every figure on it is taken from the published text of the standard or the manufacturer document named beside it, not from a secondary summary. WC Safety is an independent PPE review site: we hold no inventory and sell nothing directly, so there is no product we need this page to favour. Where sources disagree, the page says so and plans on the more conservative figure rather than picking one.
Methodology: how this page is maintained
Methodology. Figures are read from the primary source and re-checked whenever the underlying standard or a manufacturer document changes. No laboratory testing is performed for this page. Where a figure is not published, the page states that rather than estimating it, because a plausible invented number is more dangerous than an absent one.
