Respirators for Welding Fume

The exposure limits

What the federal rule says

Each entry is condensed from the paragraph cited; the paragraph itself is the rule and the link opens it.

29 CFR 1910.252(c)(4): All welding and cutting operations carried on in confined spaces shall be adequately ventilated to prevent the accumulation of toxic materials or possible oxygen deficiency. In circumstances for which it is impossible to provide such ventilation, airline respirators or hose masks approved for this purpose by NIOSH under 42 CFR part 84 must be used. In areas immediately hazardous to life, a full-facepiece, pressure-demand, self-contained breathing apparatus or a combination full-facepiece, pressure-demand supplied-air respirator with an auxiliary, self-contained air supply approved by NIOSH under 42 CFR part 84 must be used.

29 CFR 1910.252(c)(7)(iii): In confined spaces or indoors, welding or cutting operations involving metals containing lead, other than as an impurity, or metals coated with lead-bearing materials, including paint, must be done using local exhaust ventilation or airline respirators. Such operations, when done outdoors, must be done using respirators approved for this purpose by NIOSH under 42 CFR part 84.

29 CFR 1910.1026(g)(1) (hexavalent chromium, e.g. stainless steel welding): Respiratory protection is required during periods necessary to install or implement feasible engineering and work practice controls; work operations, such as maintenance and repair activities, for which engineering and work practice controls are not feasible; work operations for which an employer has implemented all feasible engineering and work practice controls and such controls are not sufficient to reduce exposures to or below the PEL; work operations where employees are exposed above the PEL for fewer than 30 days per year, and the employer has elected not to implement engineering and work practice controls to achieve the PEL; or emergencies.

What the makers' data lists for welding and cutting fume

The North chart lists the 7580P100 and 75FFP100 low-profile P100 filters; the manufacturer states the low-profile filters are designed to fit under most welding helmets (North support article 000006868 and the 7700 data sheet). The North 8419 flame-resistant welding shroud, the 7600 and 5400 welding facepieces (760008AW, 54001W) and the 8404-H5 welding attachment are on their own pages.

Assigned protection factor

Source: OSHA 29 CFR 1910.134 Table 1 (Assigned Protection Factors). The APF applies only when the respirator is used in a program that meets the standard, including fit testing of tight-fitting facepieces (29 CFR 1910.134(f)) and a cartridge change schedule (29 CFR 1910.134(d)(3)(iii)).

Respirators for Welding Fume questions

Which North filter fits under a welding helmet? The manufacturer states the 75FFP100 flat pancake filter threads directly onto the mask and is the low-profile P100; the 7580P100 uses the same media in a plastic housing (North support article 000006868).

Do welders need a respirator? 29 CFR 1910.252(c) requires ventilation first and NIOSH-approved airline respirators where ventilation is impossible in confined spaces, and NIOSH-approved respirators for lead work; exposure to the fume constituents is judged against the Table Z-1 limits and the substance standards (lead, cadmium, chromium VI).
