NWOH Fit Testing

Quantitative Respirator and EAR Fit Testing

Workers must be clean shaven or NWOH cannot provide a respirator fit test. Please discuss with your site contact if the clean shaven requirement is unclear.


Workers attending a Respirator Fit Test must be clean shaven to the standard of the company/site where they will be working. NWOH cannot provide a fit test if workers are not clean shaven.

The filter in a respirator is resistant to air-flow so if there’s a gap then some air will follow the path of least resistance through the gap. If someone has facial hair and they wear a close face fitting respirator it may look like it’s fitting ok but we’re dealing with very small particles and fibres that are so small possibly thousands are able to flow past gaps between whiskers. It's hard to say exactly how much can bypass the filter but that's not really important because the rule is As Low As Reasonably Practicable (ALARP). There are too many variables that can't be adequately quantified so we have to adopt a cautious approach. It’s considered reasonable and practicable to be clean shaven and participate in respirator fit testing but that’s only one of many methods that may need to be implemented.
