EXCEPTION: Subsection (a)(2) does not apply to high-exposure trigger tasks, as defined in subsection (b).
EXCEPTION 1: Geologic field research is not considered a high-exposure trigger task when employees work in the field with natural stone for less than 30 days in a 12-month period and use respiratory protection in accordance with Section 5144 during such work.
EXCEPTION 2: Outdoor work at quarries or open pit mines is not considered a high-exposure trigger task where the employer demonstrates that employee exposures, as defined in subsection (b)(7), are below the permissible exposure limit for respirable crystalline silica.
EXCEPTION 3: Fabrication or finishing of natural stone tombstones, monuments, memorials, burial vaults, sculptures, or related items is not considered a high-exposure trigger task where the employer demonstrates that employee exposures, as defined in subsection (b)(7), are below the permissible exposure limit for respirable crystalline silica.
EXCEPTION: The employer may provide employees with a loose-fitting PAPR (APF of 25), a full facepiece air-purifying respirator (APF of 50), a half-face PAPR (APF of 50), or another respirator providing equal or greater protection where the employer demonstrates that employee exposures to respirable crystalline silica are continuously maintained below the action level through representative air sampling conducted at least once every six months in accordance with subsection (d)(3)(A). This exception does not apply if the PLHCP or specialist recommends use of a full face, tight-fitting PAPR, or other more protective respirator.
