Can Muslim and Sikh men wear beards?
Muslim and Sikh men are permitted to wear short neatly trimmed beards. However, where a hazard clearly exists, Muslim and Sikh men may be required to modify or remove facial hair to such an extent as to enable the correct wearing of breathing apparatus, oxygen masks, or respirators. An effective seal on a respirator can only be achieved when the skin is clean shaven. In the Royal Navy all men are permitted to wear beards.
