When practicable, use shall be made of water, oil or chemicals in such noninjurious quantities, and with such frequency, as may be necessary to suppress and allay harmful dusts, fumes, mists, vapors, and gases wherever the provisions of 5141, 5143 and 5144 are impracticable or inadequate to prevent harmful exposure. The use of allaying media may also be supplementary to, or may be substituted for, other provisions of these orders when such allaying media alone would prevent harmful exposure.
