1.2 OSHA Inspections, Priorities & Inspector Credentials

1.2 OSHA Inspections, Priorities & Inspector Credentials

OSHA Enforcement Priorities

Federal OSHA and its State Plan partners field roughly 1,850 inspectors covering about 130 million workers at more than 8 million worksites — approximately one compliance officer for every 70,000 workers (OSHA, Commonly Used Statistics). Federal OSHA completed 34,696 inspections in FY 2024. Because universal inspection is arithmetically impossible at that ratio, the agency rations enforcement resources through a strict five-tier priority framework.

READ THE CHART BELOW AS A SCHEMATIC: OSHA does not publish an official percentage breakdown of inspections by priority tier. The chart depicts relative enforcement emphasis only — memorize the order of the five priorities, not the percentages.

Advance Notice Restrictions (29 CFR 1903.6)

Under Section 17(f) of the OSH Act and 29 CFR 1903.6, providing unauthorized advance notice of an OSHA inspection to an employer is strictly prohibited. The law imposes severe criminal penalties: anyone giving unauthorized advance notice is subject to a criminal fine of up to $1,000, imprisonment for up to 6 months, or both.

Advance notice may only be authorized by the OSHA Area Director under four narrow statutory exceptions:

1. In cases of imminent danger, to enable the employer to correct the hazard immediately.
2. Where the inspection must take place after regular business hours or requires special preparation.
3. Where advance notice is necessary to ensure the presence of employer and employee representatives or technical specialists.
4. In special situations where the Area Director determines that advance notice will produce a more thorough inspection.

CSHO Credentials and Entry Rights

When a CSHO arrives at a worksite, the inspection begins with credential verification. The CSHO must present official U.S. Department of Labor credentials containing a photograph and a unique serial number.

CRITICAL RULE: An inspector's badge or business card alone is not sufficient legal identification. Employers retain the right to verify credentials by calling the local OSHA Area Office before granting access.

Marshall v. Barlow's, Inc. (1978) — Warrants and Entry

In Marshall v. Barlow's, Inc. (436 U.S. 307), the U.S. Supreme Court held that employers have a Fourth Amendment constitutional right protecting against warrantless administrative searches.

• An employer has the legal right to refuse entry to a CSHO and demand an administrative search warrant.
• If refused entry, the CSHO reports to the OSHA Area Director, who requests an administrative warrant from a U.S. District Court Judge or Magistrate.
• To secure an administrative warrant, OSHA does not need to show criminal probable cause; showing that the inspection is part of a neutral administrative plan (e.g., SST program) or based on a specific employee complaint satisfies administrative probable cause.

The Three Phases of an OSHA Inspection

An OSHA inspection follows a structured three-phase protocol:

+-----------------------+     +-----------------------+     +-----------------------+
|   Opening Conference  | --> | Walkaround Inspection | --> |   Closing Conference  |
+-----------------------+     +-----------------------+     +-----------------------+

Phase 1: Opening Conference

• The CSHO presents credentials, explains the purpose and scope of the inspection, and provides copies of any employee complaints (redacting complainant identity if requested).
• The CSHO identifies trade secret areas under Section 15 to ensure confidentiality protections under 29 CFR 1903.9.
• Selection of walkaround representatives: under 29 CFR 1903.8, an authorized employee representative (such as a union representative or employee-designated safety committee member) has the right to accompany the CSHO.
• Review of required compliance documents: the CSHO inspects OSHA 300 Logs, OSHA 300A Summaries, OSHA 301 Incident Reports, written hazard communication programs, SDSs, and safety training records.

Phase 2: Walkaround Inspection

• The CSHO, accompanied by management and employee walkaround representatives, inspects facility operations, machinery, chemical storage, and work practices.
• CSHOs may take photographs, record videos, take environmental air/noise samples, and examine safety devices.
• Private Employee Interviews: CSHOs have statutory authority under Section 8(a) to conduct private, confidential interviews with non-supervisory employees out of the presence of management.
• CSHOs point out observed hazards immediately; employers are encouraged to abate hazards on the spot when feasible.

Phase 3: Closing Conference

• The CSHO conducts a closing meeting with employer and employee representatives to discuss observed safety hazards, potential violations, and apparent compliance issues.
• The CSHO details employer rights, informal conference procedures, and contesting options.
• The CSHO does not issue citations or calculate dollar penalties during the closing conference; citation decisions and penalty calculations are made subsequently by the OSHA Area Director.
