OSHA inspection walkthrough: what contractors should expect
An unannounced OSHA visit can stop work for hours. Knowing the procedure helps your superintendent stay calm, keep the inspection orderly and protect the company's interests. The core steps are in OSHA's inspection regulations.
- The compliance officer must show credentials, explain the purpose of the inspection and describe its general scope and the records they want to review.
- They can take photos and environmental samples, use personal sampling devices on employees and question employees privately.
- If entry is refused, the inspector ends or narrows the inspection, and OSHA may seek compulsory process, usually an ex parte warrant.
- An employer representative and an employee representative get the chance to accompany the inspector, and a closing conference follows.
The opening
Under 29 CFR 1903.7, conduct of inspections, compliance officers "shall present their credentials to the owner, operator, or agent in charge," explain "the nature and purpose of the inspection," and indicate generally its scope and the records they want to review. Make sure your site lead knows to ask for credentials and to call the office right away.
What the inspector can do
- Take environmental samples and photographs related to the inspection.
- Use "other reasonable investigative techniques," including attaching dosimeters, pumps, badges and similar devices to employees.
- "Question privately any employer, owner, operator, agent or employee."
Inspectors must follow your site's safety rules, wear required PPE and conduct the inspection to "preclude unreasonable disruption" of operations.
If someone refuses entry
Under 29 CFR 1903.4, objection to inspection, if entry is refused, the inspector will end the inspection or limit it to areas with no objection, find out why, and report it. The Area Director consults the Regional Solicitor, who can take action "including compulsory process." The rule names ex parte inspection warrants as "the preferred form." OSHA may also get a warrant before showing up, for example when an employer's past practice suggests a warrantless inspection will be refused.
Who walks along
Under 29 CFR 1903.8, representatives of employers and employees, a representative of the employer and one authorized by employees "shall be given an opportunity to accompany" the inspector. Employees' representative may be a third party if the inspector finds good cause. Where there's no authorized employee representative, the inspector consults a reasonable number of employees.
The closing conference
At the end, the inspector confers with the employer and informally advises of apparent violations. You can bring "any pertinent information regarding conditions in the workplace" to their attention. Have your safety documents ready.
Prep checklist for your bid and field team
- Name who meets the inspector on each project, including on GC-controlled sites.
- Keep training records, the site safety plan and OSHA 300 logs where they can be found fast.
- Take your own photos of the same conditions the inspector photographs.
