The general industry silica standard has the same exposure limit as the construction rule and none of its shortcuts. There is no Table 1 to follow, so exposure assessment is not optional. This guide covers which rule governs your work, the two limits, the written exposure control plan and the medical surveillance clock.

OSHA 29 CFR 1926.1153 is the construction silica standard. It sets a PEL of 50 µg/m³, allows Table 1 engineering controls as a compliance option, and requires written exposure control plans and medical surveillance when applicable. This guide covers each compliance option and respirator selection for concrete grinding and masonry work.
