MSA Suspension Trauma Relief System — Safety Step

A step-based suspension trauma relief system — MSA

Not every suspension trauma relief system uses straps. 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.

Key features

• Harness-mounted safety step, not a pair of straps
• Relieves suspension pressure to help maintain blood flow after a fall arrest
• Single mounted device — no unfolding loops to manage
• MSA Safety — SKU MSTSS-STD, live Amazon pricing on the linked listing

Pros & cons

Specifications

What this step is for

Equipping a full body harness with post-fall suspension relief using a single mounted step rather than deployable straps — useful for crews that prefer a simpler, always-in-place mechanism. 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.

Compatibility

Confirm the mounting point and compatibility with your specific harness model before ordering — inspect per our harness inspection reference and fitting reference.

How this step compares

For a strap-based approach instead of a step, see the 3M DBI-SALA suspension trauma strap, the FallTech 5040 (hip-pack with reflective webbing), the Guardian 10733, or the Peakworks V860303. MSA's Workman Arc Flash harness is another compatible option if you're standardizing on MSA equipment. Every harness accessory lives in the full body harness collection, connectors are covered in the carabiners & connectors collection, and lanyard options are ranked in our fall protection lanyards guide.

Safety note: a suspension trauma relief system reduces the risk of suspension intolerance after a fall arrest but does not replace a documented rescue plan — a worker suspended in a personal fall arrest system must still be rescued promptly per OSHA guidance, and every harness in use should be inspected per the manufacturer's instructions before each use. Retire the step after any fall arrest or suspension event.

Ordering FAQ

Is the MSA Suspension Trauma Safety Step in stock and ready to ship?
Yes — this listing is active and ships through Amazon. Open the linked listing for live price, availability, and delivery speed.

Is this a strap or a step?
A step — it’s a harness-mounted step device, not a pair of stand-in strap loops like some other suspension trauma relief products. The mechanism differs even though the goal is the same.

How does it relieve suspension pressure?
A worker suspended after a fall arrest presses down on the step to shift weight off the leg straps, helping maintain blood flow instead of hanging static.

How does this compare to a strap-based trauma relief product?
Both address suspension trauma; a step gives one mounted platform to push against, while stand-in straps (like the 3M DBI-SALA or FallTech 5040 sets) unfold into loops for each leg. Compare mechanism preference and harness mounting against your crew’s training.

Does this fit any harness?
It’s designed as a harness-mounted accessory — confirm the mounting point and compatibility with your specific harness model before relying on it.

Do I need to buy anything else to use this?
No additional hardware — it mounts directly to an existing full body harness. It does not replace a rescue plan or the training needed to execute one.

Is this OSHA compliant?
Suspension trauma relief addresses post-fall suspension intolerance rather than the fall arrest itself; OSHA 1926.502 governs the anchor, harness, and lanyard or lifeline in the arrest system, while a documented rescue plan is a separate requirement this step supports.

How do I inspect this before use?
Check the step and its mounting hardware for cracks, deformation, or corrosion, and confirm it deploys and locks into position as designed. Retire after any fall arrest or suspension event.

Can this be added to a harness that doesn't already have one?
Check MSA’s instructions for the mounting points and compatibility with your specific harness model before adding it.

How do I reorder for a crew?
Reorder from this page — the listing and its linked Amazon ASIN stay constant, so equipping every harness on a crew takes seconds.

Why choose a step over trauma relief straps?
Some crews prefer a single mounted step for simplicity or ease of use over deploying two separate straps — it comes down to training and what your crew practices with.

Does the step work for a worker of any size?
MSA’s listing does not specify a weight or size limit beyond the harness itself — confirm compatibility with your specific harness model and worker population against MSA’s instructions.
