A hearing conservation program begins with representative exposure information, not just earplugs. Under general-industry 29 CFR 1910.95, an 8-hour TWA of 85 dBA, or a 50% dose, is the action level for a continuing program. It is not the 8-hour PEL: Table G-16 uses 90 dBA with a 5-dBA exchange rate.
At the action level, plan monitoring, notification, protectors, training, and audiometry as applicable. Above Table G-16 levels, feasible engineering or administrative controls are required; impulse or impact noise has a 140 dB peak limit. A photo or phone reading cannot measure dose, establish an audiogram, or prove attenuation or training.
Who does this apply to?
- Use for general-industry occupational noise under 1910.95; other sectors or a specific noise standard require a separate scope check.
- The program trigger is an 8-hour TWA of 85 dBA or 50% dose, without credit for protector attenuation. The 90 dBA figure is the Table G-16 PEL, not the action level.
- At or above the action level, make protectors available at no cost, provide choice and training, and make required audiometric testing available without cost.
Implementation Steps
Identify noise-producing tasks and workers
Use process knowledge, employee interviews, equipment changes, and a walk-through to find workers who may reach the action level. Note source, task, duration, shift, and location; this screening determines representative monitoring. Add the equipment state, concurrent sources, worker position, hearing protection status, unusual production, and reason the sample represents—or does not represent—the shift. Implementation questions: which task varies by day, who covers breaks, and what change would trigger another sample?
- List presses, saws, compressors, impacts, alarms, vehicles, and temporary sources by task and shift.
- Include maintenance, sanitation, set-up, contractors, and process or layout changes.
Monitor with a defensible method
Use suitable instruments or dosimetry to measure representative exposure over the relevant workday. Explain results using the standard's TWA, dose, exchange-rate, and calibration approach; repeat monitoring after a change that may increase exposure. Illustrative scenario: a brief spot reading is low while a press runs intermittently; the assessor instead documents the production cycle, sample period, instrument checks, task changes, and affected employees. Escalate an incomplete or nonrepresentative sample rather than labeling the group below the action level. Keep employee notification and the reasoning for any repeat sample with the result.
- Document instrument identity, calibration checks, worker/task, sampling period, conditions, and calculation method.
- Sample variable and high-exposure work, and notify affected employees as required.
Control the source and the path
When Table G-16 levels are exceeded, use feasible engineering and administrative controls: maintain, isolate, enclose, reduce impact, or manage time and distance. Do not hide a controllable source with protectors; validate controls by monitoring. The control register should name the source, noise mechanism, selected measure, affected task, temporary protection, project owner, verification method, and post-control result. Escalate when a control increases another hazard, changes production, depends on a vendor, or leaves employees relying on protectors while the source remains unexplained.
- Create a control log that names source, selected measure, owner, due date, and post-control exposure.
- Coordinate purchasing and mark areas where hearing protection is required or available.
Provide protectors, training, and choice
For employees at or above 85 dBA, provide protectors at no cost, offer suitable variety, and train on selection, fit, use, care, and limits. Explain that attenuation cannot be credited when deciding whether the action level is reached.
- Document protector options, fit discussions, replacement, hygiene, and supervisor follow-up.
- Teach adjustment and recognition of a poor fit or damaged product; signs do not replace measurement.
Run baseline and annual audiometry
Make testing available at no cost. The standard generally calls for a baseline within 6 months of first qualifying exposure, or within 1 year under the mobile-test-van exception, then annual audiograms. Schedule the quiet period and follow the standard's response to a threshold shift. Keep an eligibility tracker with first qualifying exposure, baseline path, test date, notification, professional follow-up, and confidentiality owner; do not put unnecessary medical detail in a supervisor spreadsheet. Completion evidence is a completed notification and follow-up path, not merely a vendor invoice.
- Track first qualifying exposure, baseline deadline, annual test date, notification, and follow-up.
- Protect medical confidentiality and investigate task, exposure, or protector changes when results require action.
Evaluate the program after change
Review noise data, professional audiometric follow-up, employee feedback, control performance, and training. A new process, result, complaint, or protector change should open a dated review that names the next check. Ask whether the source changed, the sampled worker still represents the group, employees can select and fit protection, and open controls were verified in the field. Close the review with the decision, owner, evidence, and remaining uncertainty rather than a generic “program reviewed” note.
- Compare current exposure and control evidence with the prior task and document unresolved uncertainty.
- Close actions only after field verification and retain records under 1910.95 and medical-record rules.
Document planning checklist
Use this planning list to organize applicable records. Suggested owners and review triggers are workflow recommendations; the linked standards determine which documents and retention periods are legally required.
| Document / Record | Purpose | Owner | Review Cadence |
|---|---|---|---|
| Noise source and affected-employee inventory | Maps sources, tasks, durations, shifts, and employees who may reach the action level. | Industrial hygiene or safety coordinator | At startup and after equipment, process, layout, or staffing changes |
| Noise monitoring and calibration record | Preserves representative sampling conditions, instrument checks, dose, TWA, and notifications. | Qualified noise assessor | For each sampling event and when a result or method changes |
| Noise-control action register | Tracks engineering or administrative controls, owners, deadlines, and follow-up measurements. | Operations engineering lead | At each project milestone and after post-control monitoring |
| Hearing protector selection and training record | Documents options, availability, fit instruction, use, care, and replacement. | Area supervisor | At assignment and after protector, task, or exposure changes |
| Audiometry eligibility and follow-up tracker | Tracks baseline, annual tests, notifications, and required response without exposing unnecessary medical detail. | Occupational health record custodian | Before baseline and annual testing windows; after professional follow-up |
| Annual program evaluation | Connects monitoring, controls, training, feedback, and open actions. | Program administrator | At review and after a significant change |
Common Pitfalls
Calling 85 dBA the PEL
85 dBA is the general-industry 8-hour TWA action level for the hearing-conservation program; 90 dBA is the Table G-16 8-hour PEL. Keep the terms and response paths separate.
Using a spot reading as a dose
A phone or brief meter reading cannot represent an 8-hour TWA, dose, impulse peak, or changing task. Use defensible monitoring.
Treating audiometry as a paperwork event
A test date without baseline timing, notification, confidentiality, and follow-up does not show that the program learned from the result.

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
