This section does not apply to tasks listed and performed in accordance with Table 1 of WAC 296-840-110 Specified exposure control methods.
(1) Engineering and work practice controls. You must use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the PEL, unless the employer can demonstrate that such controls are not feasible. Wherever such feasible engineering and work practice controls are not sufficient to reduce employee exposure to or below the PEL, you must nonetheless use them to reduce employee exposure to the lowest feasible level and must supplement them with the use of respiratory protection that complies with the requirements of WAC 296-840-125 .
