Powered-air welding: can you prove it?

You can buy the right respirator and still fail an inspection. For a 3M™ Speedglas™ G5-01VC with an Adflo™ powered-air system, suitability is only half the legal duty — you also have to show it was chosen, checked and maintained correctly. This is the records-and-evidence side nobody hands you with the kit.

"No fit test" is not "no paperwork"

A loose-fitting powered headtop like the Adflo does not need a face-fit test — it works with beards and stubble, with no per-person test to schedule. That is a genuine saving over tight-fitting masks. It is also where most shops trip up: dropping the fit test does not drop the rest of the respiratory programme.

With powered air you still owe a documented selection, training, supervision, maintenance to the manufacturer's instructions with records, and a pre-use check before every use. Powered air simply swaps the fit-test regime for an airflow-check-and-maintenance regime — lighter, but only if you actually run it and write it down. A pre-use check nobody records did not happen.

Who owns what — the evidence at a glance

Three roles, one evidence trail. The gaps are usually where two people each assumed the other had it. Split it cleanly and half the battle is won.

The four records in the pack

Each row in the responsibility map becomes a record you can hand over. The pack gives the three roles a shared shape to fill in, instead of three people each keeping half a record.

01

RPE selection & suitability record

The four-step "why this respirator for this fume" sheet: the hazard, the control hierarchy (LEV first), the protection level (APF), and the reason for powered air. Makes "suitable" a documented decision, not an opinion.

02

Daily pre-use airflow check log

Date · unit ID · airflow pass/fail · issues reported. A print-ready sheet for the welding bay. Log against a unique unit ID so you can show an inspector a continuous history for a specific blower.

03

Consumables & service log

Scheduled pre-filter, particle filter, spark arrestor, battery and breathing-tube checks — with parts used and a named responsible person. Turns maintenance into a traceable evidence chain, kept ≥5 years (COSHH).

04

Training & instruction record

Wearer · date · topics (donning, the airflow check, consumables, and the limits) · trainer. Including the confined-space limit, recorded as a limit.

The hard limit, and what this pack is

Powered air is not supplied air A powered air-purifying respirator filters the surrounding air; it does not supply oxygen. It is not suitable for oxygen-deficient or potentially oxygen-deficient atmospheres, or confined spaces where shielding or purging gas can displace the air — those call for a supplied-air system. Write that boundary into your risk assessment and training record.
  • An adaptable starting framework to sit underneath your own COSHH assessment — not a guarantee of compliance. Your assessment and your work decide the detail.
  • APF and TH3 figures referenced (APF 20 minimum for welding; TH3 loose-fitting powered = APF 40) are HSE figures from HSG53.
  • ISO 14731 and EN 1090 do not mandate a PAPR; they place welder health & safety in the welding coordinator's scope. Your COSHH assessment decides the level of protection.
  • Keep records of each RPE examination, test and repair for at least five years from the date made (COSHH).
