RESP-FIT is aware of the recent adoption of a beard covering technique being used in fit testing tight fitting respirators, particularly in Healthcare. This technique, known as the Singh Thatta, Â involves the use of an exercise resistance band wrapped around a wearers chin/beard and tied up on top of the head to create a smoother surface over the beard or facial hair, aiming for a better sealing surface area. Disposable balaclavas have also been used in this way to try and improve the tight fitting seal.
All international standards, including AS/NZS 1715:2009, ISO 16975-3, OSHA 1910.134 and others, clearly state that there should be no facial hair on a wearers’ face underneath a tight-fitting respirator sealing surface area. Facial hair prevents an adequate seal from being achieved, and the level of protection is neither reliable nor predictable.
RESP-FIT does NOT recommend the use of this technique for a number of reasons as outlined in the following position statement.
