D. In areas where employees are exposed to toxic and nuisance gases and dusts, adequate ventilating and collecting systems shall be provided to insure that such toxic and nuisance gases and dusts are maintained within the recommended maximum allowable concentration as proposed and adopted by the American Conference of Governmental Industrial Hygienists. Where this cannot be accomplished and employees are required to work in excessive concentrations, NIOSH approved respirators or supplied fresh air breathing equipment shall be provided.
E. Equipment shall be provided to test for the presence of toxic and nuisance gases and dusts and qualified personnel will make and evaluate such tests.
