Posted By John Webster I would have thought we all had some sort of obligation to our fellows to come into work clean and fresh smelling, and not to dump piles of foul smelling material in washrooms :-) The ACoP to the Welfare Regs is not specific, but it does require employers to provide adequate, suitable and secure space for storing staff's own clothing, and (so far as is reasonably practicable) for drying clothing. "Adequate" and "suitable" could require the special 'nature' of these garments to be considered. Adequate ventilation to the workplace is required and described as drawing clean, fresh air from outside the workplace, removing and diluting warm humid air. If the workplace contains.....other sources of......fumes or vapours, more fresh air will be needed to provide adequate ventilation. There is also a requirement for sanitary facilities and washrooms to be adequately ventilated. It's not clear if the same standard of "adequate" applies to washrooms (or are they part of the workplace anyway), but I would take it to be at least sufficient to remove foul smells. But note that unless special work clothing has to be changed into, you do not have to provide changing facilities (the law basically assumes that staff will only need a place to hang a wet jacket or overcoat). So you could provide a place for storing the offending items elsewhere than within a washroom or the workplace.
