People come in all sorts of shapes and sizes. It is unlikely that one particular type or size of RPE facepiece will fit everyone. Therefore, manufacturers offer different size and shape facepieces such as masks, visors and hoods.
The performance of tight-fitting facepieces depends on achieving a good contact between the wearer’s skin and the face seal of the facepiece. A poor fit will significantly reduce the protection the RPE can provide you. Any reduction in protection can put your life in danger or may lead to immediate or long-term ill health.
It is useful to check that you can put on your RPE correctly. Correct fitting of the facepiece at all times is vital to prevent exposure.
