This service is provided so that operatives wearing masks are using a mask that fits them correctly. This test needs to be carried out for both disposable paper masks and half face rubber mask types.

• The delegate will wear their selected RPE and perform a sequence of light exercises. (A trained operator assesses the exercises. The operator will conduct either a qualitative or quantitative test).
• The quantitative test is for all tight-fitting masks.
• The qualitative test is for half-mask but not full masks.
