Standard Overview

OSHA’s recent final rule on limiting exposure to respirable crystalline silica was issued to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease that has been linked to high levels of silica. The regulations are addressed in 1910.1053 for general industry and maritime and 1926.1153 for construction.

Because OSHA’s previous permissible exposure limits (PELs) for silica were outdated, the new PEL for workers is 50 micrograms of respirable silica per cubic meter of air (µg/m3) at an 8-hour time-weighted average (TWA).

Determine if work tasks expose employees to respirable crystalline silica by reviewing Table 1 (1926.1153(c)(1)), or by conducting an exposure assessment
For tasks exceeding the PEL, notify affected employees and implement the required engineering and work practice controls, and level is respiratory protection
Review housekeeping practice to eliminate any dry sweeping/brushing activities that could exposure employees to respirable crystalline silica
Establish a written exposure that’s readily available and reviewed at least annually
Make medical surveillance available at no cost to employees
Communicate hazards to employees and provide training on the hazards, tasks and safety measures in place
Accurately record and maintain all exposure measurements

Demarcating Regulated Areas

A sign at each entrance must be posted to notify employees that they are entering a regulated area, the hazards and need for respiratory protection.

Browse Compliant Silica Signs

To decrease the number of employees exposed to respirable crystalline silica, regulated areas must be marked. Employers can use floor marking tape, stanchions, barricades or cones to mark the boundaries of regulated areas.

Respiratory Silica in Absorbents

One of the most common compositions for granular absorbents is diatomaceous earth, which is 80-90% silica based. As a safer, non-silica solution to spill response and absorbents, Brady SPC absorbent pads and rolls are a cost-effective product for leaks, drips and spills.
