Changerooms

Part 1 of this Code of Practice is for the guidance of designers in planning facilities for protecting personnel against the contamination which arises in the day-to-day operation of nuclear reactors, chemical plant, effluent treatment plant, laboratories and their associated work-shops. The designs should be so arranged that, with their privacy respected as far as practicable, personnel can find, readily to hand, and in the appropriate order - clothing storage, protective clothing, washing facilities, toilets and monitors, etc and pass through to their work quickly and easily with the minimum of working time lost, and on return, leave clean. This Code of Practice gives guidance on minimum requirements per individual but, bearing in mind that changerooms are empty between shifts, the space can be reduced to an optimum by economic study of the timing and scale of occupation. In respect of heating and ventilation, warm air, extracted or induced through the lockers may be installed, preferably the former, since it prevents turbulence and jet effects which could disturb the absolute demand of air flow from the inactive to the active side of 1 m/sec minimum at all times.
