Mine cleanliness and hygiene requirements mandate sanitary workplaces, dust control, protective gear, and supervised waste disposal. Employer responsibilities in every mine include maintaining all workplaces, workrooms, passageways, staircases, storerooms and service rooms in sanitary and hygienic condition, keeping walls, ceilings, windows and skylights clean, and ensuring workroom floors remain clean, dry and non-slippery as far as possible. Where wet work processes are carried on, effective drainage, dry standing places and anti-skid footwear and other suitable protective gear must be provided without expense to employees.
