OSHA Silica Compliance for Construction: The Complete Guide

Why Silica Matters in Construction

Respirable crystalline silica — the invisible dust created by cutting, grinding, drilling, or crushing concrete, stone, and masonry — causes silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease, according to OSHA. In its 2016 final rule (81 FR 16286, March 25, 2016), OSHA estimated that about 2.3 million workers are exposed, 2.0 million of them in construction, and that the rule, once fully effective, would prevent 642 deaths and 918 moderate-to-severe silicosis cases every year.

OSHA's construction silica standard (29 CFR 1926.1153) has applied since June 23, 2017 (1926.1153(k)(2)), and it is still cited often: in FY2025, federal OSHA cited 1926.1153 632 times in construction (NAICS 23), across 271 inspections (OSHA IMIS cited-standard data, extracted August 15, 2026).

This guide covers everything you need to know to comply in 2026 — from Table 1 to exposure monitoring, medical surveillance, and the written plan. Under 29 CFR 1926.1153, construction employers keep respirable crystalline silica at or below 50 micrograms per cubic meter over an 8-hour day, either by following the Table 1 controls for each listed task or by assessing exposure, and in both cases they need a written exposure control plan and a competent person.

The engineered-stone wake-up call

Silica is not a historical hazard. Engineered ("quartz") stone, the countertop material now in many kitchens, has brought an aggressive, accelerated silicosis to the young workers who cut and polish it. It is a reminder that the controls below are not paperwork; see the data in the silicosis comeback, and every requirement organized in the Silica hub.

The Basics: PEL, Action Level, and Why They Matter

Permissible Exposure Limit (PEL)

The construction PEL for respirable crystalline silica is 50 µg/m³ as an 8-hour TWA (1926.1153(d)(1)).

Action Level

The action level is 25 µg/m³ (half the PEL, 1926.1153(b)). Under the alternative method of 1926.1153(d), it decides who must be assessed:

• Exposure assessment for each employee who is or may reasonably be expected to be exposed at or above the action level (1926.1153(d)(2)(i))
• Periodic monitoring at 3 or 6 months, depending on the last result (1926.1153(d)(2)(iii))

Note: the medical surveillance trigger is separate — it is based on required respirator use for 30+ days/year (1926.1153(h)(1)(i)), not the action level. A written exposure control plan is required for any task involving silica exposure under 1926.1153(g), regardless of the action level.

Common Activities That Generate Silica Dust

Cutting, grinding, and drilling concrete and masonry, tuckpointing, jackhammering, and dry sweeping all put respirable silica in the air. The first five each have an entry on Table 1 with their own controls; dry sweeping is restricted by the housekeeping rule (1926.1153(f)(1)).

Table 1: The Simplified Compliance Path

What Is Table 1?

Table 1 (29 CFR 1926.1153(c)) is the simplest compliance path. It lists 18 common construction tasks with pre-approved engineering controls, work practices, and respiratory protection. If you fully and properly implement Table 1 for a task (1926.1153(c)(1)), you do not need to assess exposure for it.

The 18 Table 1 Tasks

1. Stationary masonry saw
2. Handheld power saw (any blade diameter)
3. Handheld power saw for fiber-cement board (blade ≤ 8 in, outdoors only)
4. Walk-behind saw
5. Drivable saw (outdoors only)
6. Rig-mounted core saw or drill
7. Handheld and stand-mounted drills (incl. impact and rotary hammer drills)
8. Dowel drilling rigs for concrete (outdoors only)
9. Vehicle-mounted drilling rigs for rock and concrete
10. Jackhammers and handheld powered chipping tools
11. Handheld grinders for mortar removal (tuckpointing)
12. Handheld grinders for uses other than mortar removal
13. Walk-behind milling machines and floor grinders
14. Small drivable milling machines (less than half-lane)
15. Large drivable milling machines (half-lane and larger)
16. Crushing machines
17. Heavy equipment/utility vehicles used to abrade or fracture silica-containing materials (e.g., hoe-ramming, rock ripping) or during demolition
18. Heavy equipment/utility vehicles for grading and excavating

Table 1 Requirements (All Tasks)

For every Table 1 task, you must:

1. Use the specified engineering control (e.g., integrated water delivery, or a dust collection system with a filter of 99% or greater efficiency)
2. Follow the specified work practices (e.g., operate and maintain controls per manufacturer instructions)
3. Provide the specified respiratory protection when required (APF 10 or APF 25, depending on the task and how long it runs)
4. Ensure adequate water flow: for wet methods, water must flow at rates sufficient to minimize the release of visible dust (1926.1153(c)(2)(ii)); indoors, provide exhaust as needed to keep visible dust from accumulating (1926.1153(c)(2)(i))

When Table 1 Doesn't Work

You cannot use Table 1 if:

• Your task is not listed in the 18 entries
• You cannot fully and properly implement the specified controls, including enough water to minimize visible dust

In these cases, you must use the Alternative Exposure Control Methods under 1926.1153(d): assess exposure and keep it at or below the PEL (1926.1153(d)(1) and (d)(2)).

---

Exposure Monitoring (When Required)

Initial Monitoring

If you are NOT using Table 1, you must assess each employee's exposure. Options:

1. Objective data: data such as industry-wide survey results that reflect conditions closely resembling yours, or with a higher exposure potential (1926.1153(b)), used under the performance option (1926.1153(d)(2)(ii))
2. Air monitoring — personal breathing zone sampling using a calibrated pump and cyclone sampler (scheduled monitoring option, 1926.1153(d)(2)(iii))

Periodic Monitoring

Under the scheduled monitoring option:

• At or above the action level but at or below the PEL: re-monitor within 6 months (1926.1153(d)(2)(iii)(C))
• Above the PEL: re-monitor within 3 months (1926.1153(d)(2)(iii)(D))
• Below the action level on a later result: keep monitoring every 6 months until two consecutive measurements, taken 7 or more days apart, are below the action level (1926.1153(d)(2)(iii)(E))

Telling Employees the Results

• Results must be provided to employees within 5 working days, individually in writing or by posting (1926.1153(d)(2)(vi)(A))
• If above the PEL, the notice describes the corrective action being taken (1926.1153(d)(2)(vi)(B))

Written Exposure Control Plan

Every employer whose workers engage in tasks involving silica exposure (including Table 1 tasks) must have a written exposure control plan under 1926.1153(g) — this requirement is not gated on the action level. This must include:

Required Elements (1926.1153(g)(1))

1. Task descriptions — each task involving silica exposure
2. Control methods — engineering controls and work practices for each task
3. Housekeeping measures: no dry sweeping where wet sweeping or HEPA vacuuming is feasible (1926.1153(f)(1))
4. Restricted access: procedures to restrict access to work areas when necessary, including exposures generated by other employers

Two more duties come with the plan: review it at least annually and update it as necessary (1926.1153(g)(2)), and designate a competent person to make frequent and regular inspections that implement it (1926.1153(g)(4)).

Common Plan Gaps

• Generic boilerplate plans not specific to actual jobsite tasks
• No competent person named or trained
• Housekeeping section allows dry sweeping
• Plan not updated when new silica-generating tasks are added
• No sign that employees know the controls in the plan (1926.1153(i)(2))

---

Medical Surveillance

Who Needs It?

Each employee who is required to use a respirator for silica work for 30 or more days per year (1926.1153(h)(1)(i)). Each day on which the standard requires the employee to wear a respirator counts as one of the 30 days. Note: this construction trigger is respirator-based — it is not the same as the action-level-for-30-days trigger that applies under the separate general-industry standard (1910.1053).

Initial Exam (within 30 days of assignment, 1926.1153(h)(2))

• Medical and work history (emphasis on respiratory system)
• Physical examination focused on the respiratory system
• Chest X-ray
• Pulmonary function test (spirometry)
• Latent tuberculosis (TB) test

Periodic Exams

• Every 3 years (or more frequently if recommended by the PLHCP), without the TB test (1926.1153(h)(3))
• Physician may recommend additional tests based on findings

Employer Obligations

• Make exams available at no cost to the employee (1926.1153(h)(1)(i))
• Provide exams at a reasonable time and place
• Give the examining PLHCP a copy of the standard and information about the employee's exposure, respiratory protection used, and prior exam results (1926.1153(h)(4))

---

Housekeeping and Prohibited Practices

Prohibited Unless No Alternative Works

• Dry sweeping or dry brushing of silica dust (unless wet sweeping, HEPA vacuuming, or similar methods are not feasible, 1926.1153(f)(1))
• Compressed air for cleaning clothing or surfaces (unless used with a ventilation system that effectively captures the dust cloud, or no alternative method is feasible, 1926.1153(f)(2))

Accepted Alternatives

• HEPA-filtered vacuum for cleanup
• Wet sweeping with adequate dust suppression
• Remove accumulated dust before it becomes airborne

---

Training Requirements

Each covered employee must be able to demonstrate knowledge and understanding of (1926.1153(i)(2)(i)):

1. Health hazards of silica exposure (silicosis, lung cancer, COPD, kidney disease)
2. Tasks that may involve exposure
3. Engineering controls, work practices, and respiratory protection measures
4. Purpose and description of the medical surveillance program
5. The contents of 29 CFR 1926.1153
6. Identity of the competent person

1926.1153(i)(2) sets no schedule of its own. Silica also belongs in your HazCom program (1926.1153(i)(1)), so HazCom training at initial assignment and on new hazards (1910.1200(h)(1)) covers it too, and the employer must make a copy of the standard readily available without cost (1926.1153(i)(2)(ii)).

---

The Competent Person

1926.1153(b) defines the silica competent person as someone who:

• Can identify existing and foreseeable silica hazards
• Has authorization to take prompt corrective action
• Conducts frequent and regular inspections of job sites, materials, and equipment (1926.1153(g)(4))
• Ensures controls are properly implemented and maintained

The competent person does NOT need to be a certified industrial hygienist — but they must be trained and knowledgeable about silica hazards and the specific controls in use.

Enforcement Reality: The Gaps a Site Walk Shows

OSHA's silica National Emphasis Program (CPL 03-00-023, February 4, 2020) sends inspectors to workplaces with silica exposure. On a jobsite, these are the gaps that show:

1. Visible dust — the first and most obvious indicator
2. Absence of water or dust collection on cutting/grinding tools
3. No written exposure control plan on the jobsite
4. No competent person identified
5. Dry sweeping of concrete dust
6. Workers without respirators in dusty conditions (without documented exposure data showing levels below the PEL)
7. No medical surveillance for workers required to wear respirators 30 or more days a year

How Penalties Add Up

Each serious item carries up to $16,550 (29 CFR 1903.15(d)(3)), and a silica inspection that finds several gaps can be cited item by item, for example:

• No exposure control plan (1 citation)
• No competent person (1 citation)
• Inadequate engineering controls per task (1+ citations)
• No medical surveillance (1 citation)
• No employee training (1 citation)
• Housekeeping violations (1 citation)

In FY2025, the 632 federal construction citations of 1926.1153 carried $1,219,150 in penalties at their current amounts (OSHA IMIS, extracted August 15, 2026).
