An employer must provide respiratory protective equipment to each employee who carries out an engineered stone process. This applies in addition to the tool-based water, extraction or ventilation controls in r 319S, so respirators are a further layer and never a substitute for them. Training in use, fit, maintenance and storage of the equipment is required by r 319W. Act compliance is through s 21.
