Silica Exposure Controls
Spot visible dust-control gaps on the job site.
Use visual review to prompt a task-specific silica assessment, then verify controls, sampling or Table 1 applicability, respiratory protection, training, and records.

Try it on a respirable crystalline silica photo
OSHA Scan may flag visible concerns. A photo cannot measure airborne respirable crystalline silica or verify an exposure limit, control efficiency, respirator fit, medical surveillance, or a written exposure-control plan.

Only upload photos you have permission to use, and avoid images showing personal, customer, or confidential information. Demo photos and results are held privately for up to 48 hours so you can save them to a free account; unclaimed photos are deleted automatically. Results are an AI-assisted preliminary review, not an official OSHA determination.
What the AI can and can't detect
OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.
What it can catch from a photo
- Missing or incorrect PPE that is visible in the frame
- Unprotected edges, open holes, and visible fall hazards
- Housekeeping, trip, and blocked walkway or exit hazards
- Visible electrical, struck-by, and equipment-guarding hazards
What a photo can't tell it
- Hazards hidden from view or anything outside the photo
- Exact heights, distances, weights, or measurements
- Training records, procedures, or how equipment is actually used
- Full legal compliance or an official OSHA pass/fail determination
A photo cannot measure airborne respirable crystalline silica or verify an exposure limit, control efficiency, respirator fit, medical surveillance, or a written exposure-control plan. It can only flag visible task and control cues.
Important Limitation: A photo cannot measure airborne respirable crystalline silica or verify an exposure limit, control efficiency, respirator fit, medical surveillance, or a written exposure-control plan. It can only flag visible task and control cues.
Quick Answer
Respirable crystalline silica is generated by tasks such as cutting, grinding, drilling, or crushing silica-containing materials. OSHA has separate construction and general-industry/maritime standards requiring exposure controls and worker protection.
Reference: 29 CFR 1926.1153; 29 CFR 1910.1053
Understanding the Silica Hazard
Cutting, grinding, drilling, crushing, or otherwise disturbing stone, concrete, mortar, brick, engineered stone, and other materials can generate respirable crystalline silica. The particles are not reliably visible even when a larger dust cloud is visible.
Construction and general industry/maritime have separate OSHA standards. Determine the applicable standard, task, material, control method, exposure assessment, housekeeping, respiratory protection, medical-surveillance, and written-plan duties before describing a task as controlled.

Visual Indicators of Silica-Dust Tasks
The reviewed scene shows visible dust around a masonry-cutting task. Visual review can flag a control check; it cannot infer airborne concentration or a safe exposure.
1
Dust-generating task
Flag cutting, grinding, drilling, or crushing for a task and material review.
2
Visible dust
Record a visible dust cloud as a prompt for controls and exposure assessment; respirable silica may be present without visible dust.
3
Control cues
Note whether water delivery, local exhaust, enclosure, or dust collection is visibly present; do not claim it is effective.
4
Housekeeping cue
Flag dry sweeping or compressed air for review where safer effective alternatives are available.
Controlling Silica Exposure
The reviewed scene shows a masonry worker using respiratory protection and supports a controls-documentation workflow. Visible PPE is not proof of fit, certification, or correct selection.
Use engineering controls
Apply water at the source, local exhaust, enclosures, or other controls suited to the task and applicable standard.
Use Table 1 or assess exposure
For construction, follow the specified method when applicable or use the alternative exposure-control method and required assessment.
Control housekeeping
Use effective, safe alternatives to dry sweeping or uncontrolled compressed air where available.
Respiratory and medical programs
When required, implement selection, fit, use, training, medical evaluation, and surveillance through the employer's qualified program.
Paused
Silica Safety Training
Training must be task-specific and explain health effects, exposure-generating work, controls, housekeeping, respiratory protection, and the site plan.
- Health effects of respirable crystalline silica exposure
- Materials and tasks that may generate exposure at the worksite
- Engineering controls, work practices, housekeeping, and respiratory protection
- The written exposure-control plan, access restrictions, reporting, and medical-surveillance process when applicable
Documenting Silica Controls
Keep the task/material inventory, applicable standard, written exposure-control plan, Table 1 or alternative method, exposure assessment and laboratory results, engineering-control checks, housekeeping, respirator and fit records, training, medical-surveillance eligibility, and corrective close-out. Attach dated photos only as visible evidence.
A photo cannot establish an airborne concentration, 8-hour TWA, PEL/action-level result, control capture efficiency, respirator fit, or medical record. Route those questions to industrial-hygiene and respiratory-program personnel.
Photo-based reviews support documentation. Your responsible program owner must arrange on-site verification by people with the qualifications and designated roles required for the task.

Frequently Asked Questions
Q.Can visual AI tell me whether air quality is safe?
A.No. It cannot measure airborne silica, an 8-hour TWA, the PEL, an action-level result, or control efficiency. Use the applicable OSHA method and qualified exposure assessment.
Q.What is Table 1?
A.Table 1 in the construction standard pairs listed tasks with specified engineering controls, work practices, and respiratory-protection conditions. Confirm that the actual task and conditions fit the table.
Q.Does visible respiratory protection prove compliance?
A.No. A photo cannot verify selection, NIOSH approval, fit, medical evaluation, training, use, or exposure conditions.
