Under the old WES system, exposure standards worked like a guideline — a benchmark businesses aimed to stay under. The new WEL framework changes the legal character of that number entirely: a limit that must not be exceeded, full stop.

• Over 200 substances have updated thresholds under the new WEL list
• 177 substances will have their exposure limits reduced — tighter than before
• A set of substances classed as non-threshold genotoxic carcinogens (NTGCs) will have no "safe" exposure limit at all
• The transition date is described by regulators as immovable — no extension for businesses that aren't ready

Hardest hit: mining, construction, manufacturing, welding, and logistics — anywhere dust, fumes, or diesel particulate matter (DPM) is part of the daily environment.

A disposable P2/P100 mask relies on one thing working perfectly, every shift: a correct face seal. Facial hair, movement, sweat, and other PPE (glasses, hard hats, comms headsets) can all quietly compromise that seal — and under a stricter WEL ceiling, "quietly compromised" isn't good enough anymore.

None of this replaces engineering controls — ventilation and dust suppression still come first. But for tasks where controls alone can't guarantee compliance with the new WEL, PAPR is the next serious line of defence.

KameLo carries the RPB PX5 powered air system alongside GVS Elipse respirators - so your team can match the level of protection needed to complete the job and stay protected.

1. Review current exposure levels against the new WEL thresholds for your industry's key contaminants.
2. Audit your PPE program — are workers relying solely on disposable respirators where the new limits tighten?
3. Check fit-testing records — if they're out of date, now's the time to update them.
4. Decide which high-exposure roles should move to powered air protection ahead of the deadline.
5. Confirm supply early — PAPR systems and filters can have lead times heading into the deadline.
