If your construction crew grinds, cuts, drills, or demolishes concrete, masonry, brick, or stone anywhere in the country, OSHA's silica standard applies to them. Fully. With no small-employer exemption, no grandfather clause for established work practices, and no tolerance for exposure levels that were standard practice a decade ago.
Respirable crystalline silica is classified as a known human carcinogen. Silicosis — the lung disease caused by silica exposure — is irreversible and progressive. OSHA's 2016 standard (29 CFR 1926.1153, fully enforced since 2018) reflects the agency's view that this is not a matter of industry convenience. It's a matter of workers going home without permanent lung damage.
This guide covers what the standard actually requires, where New York contractors are most frequently cited, and how to build a compliance framework that holds up to OSHA scrutiny.
What the Standard Actually Requires
The Permissible Exposure Limit
The OSHA silica PEL for construction is 50 micrograms per cubic meter of air (50 μg/m³) as an 8-hour time-weighted average. The Action Level — the threshold at which enhanced controls and medical surveillance are required — is 25 μg/m³. These are significantly lower than the prior PELs, which means that exposure levels that were technically compliant before 2016 may not be compliant today.
Table 1: The Engineering Controls Compliance Path
The most important compliance mechanism in 1926.1153 is Table 1 — a task-by-task specification of the engineering controls and work practices that, when fully implemented, are presumed to maintain employee exposures below the PEL without requiring individual air monitoring.
Table 1 covers the most common silica-generating construction tasks: handheld power saws, grinders, jackhammers, drills, rotary hammers, heavy equipment like dozers and scrapers, and stationary masonry saws. For each task, the standard specifies the control method — wet methods, local exhaust ventilation, integrated water delivery, or HEPA vacuum systems — and the required respiratory protection.
The Table 1 Trap
Using Table 1 controls exempts employers from air monitoring only if the controls are fully and consistently implemented as specified. A grinder equipped with an integrated water delivery system that runs dry halfway through a task is not Table 1 compliant for that task. Field verification of control implementation — not just equipment presence — is what OSHA evaluates.
When Air Monitoring Is Required
If Table 1 controls are not fully implemented, or if a task is not covered by Table 1, employers must assess employee exposures through air monitoring or objective data (such as previous monitoring data for identical tasks under identical conditions). When monitoring shows exposures between the Action Level and the PEL, enhanced respiratory protection and more frequent monitoring are required. Above the PEL, the full suite of engineering controls, respiratory protection, and administrative controls applies.
The Written Exposure Control Plan
Every employer covered by 1926.1153 must maintain a written Exposure Control Plan that identifies: tasks involving silica exposure, engineering controls used for each task, the respirators used, information and training provided, and the procedures for restricting access to high-exposure areas. The plan must be updated when new tasks are added or when changes in work conditions affect silica exposures.
Where NY Contractors Are Most Often Cited
Inadequate or Absent Engineering Controls
The most frequent citation category is failure to implement the Table 1 engineering controls — either because the equipment wasn't present, wasn't maintained, or wasn't used consistently. An integrated water delivery system on a saw that isn't turned on provides no exposure control and no Table 1 compliance protection.
Missing or Inadequate Written Exposure Control Plans
The written ECP requirement is specific and frequently unmet. Plans that are generic, that don't identify specific tasks and controls, or that haven't been updated to reflect current work activities are cited as non-compliant. A construction site with six different silica-generating tasks needs an ECP that addresses all six — not a boilerplate document that references 'dusty work.'
Respiratory Protection Selection Errors
Table 1 specifies the minimum respiratory protection required for each task and control combination. Some task/control combinations require only a half-facepiece with N95 filters. Others require a half-facepiece with P100 filters. Others require a powered air-purifying respirator. Using the wrong respirator class for the specified task is a citation — even if the employee has a valid fit test record for the respirator they're wearing.
Medical Surveillance Gaps
Employees who are exposed at or above the Action Level for 30 or more days per year must be offered medical surveillance, including a questionnaire and a chest X-ray, at no cost to the employee. This is a frequently missed requirement on large construction projects where subcontractor employees work on-site for extended periods.
Building a Compliant Silica Program for Your NY Operation
A defensible silica compliance program for a New York construction operation has four functional components:
Task inventory and Table 1 mapping: Every silica-generating task on your site, matched to the Table 1 row that governs it and the specific controls required
Equipment and control verification: A documented inspection protocol confirming that Table 1 controls are present, functional, and consistently used
Respiratory protection program: Site-specific written RPP, fit testing records, and medical clearances for every employee using respiratory protection
Written Exposure Control Plan: Current, task-specific, accessible to employees, and updated when site conditions change
The Technical Site Audit and Readiness Protocol is designed for exactly this use case — providing the framework to assess compliance posture across silica, respiratory protection, HazCom, and documentation standards in a construction or field environment.
