Dear All, Seeking some advise on use of cowl hoods (enclosed) hoods for use with RPEs. Having a few individuals who for religious reasons cant have a clean shaved face, but are involved in activities where RPEs are mandated, is unable to undergo fit test requirements. A suggestion has been made that instead of face masks, we could modify to a full head/cowl shaped units and use them. My query is, irrespective of the type of masks we use, isnt there a need to do a fit test to validate the APF? Or fit test is only required for face masks or ori-nasal masks? Any reference to substantiate the requirement is appreciated. Looking forward to your advise. Regards, Prads

Do a google (other search engines are available) for positive pressure RPE. These will be what you require. Warning though, they are much more expensive (although I would argue they are much better protection, as they are less reliant on the person to create a seal.

Where the airborne contaminant is also a skin irritant/sensitiser they also protect the sensitive skin on the scalp and face. I have encountered situations where airborne skin exposure with someone wearing a normal half-mask has resulted in skin reactions and also was shown to be contributing to systemic uptake.

fit test is for all masks, however there is Qualitive (for 1/2 face masks) and Quantitive (for air fed masks), the 2 masks test in different ways. A qualitive would be no use for a full face mask as the air feeds in differently

Thank you all for your valuable inputs. My question is whether fit test is required only for tight/close fitting masks or whether irrespective of the type of masks and the nature of air fed (demand or positive pr), we need to do a fit test?

Fit testing is only for masks that are designed to form a seal to the face. It's not needed for hoods which I think is what you are describing.
