Subcontractor safety prequalification and OSHA data

Updated 12 November 2026. Written by Clearsheet. Data referred to here comes from the US Department of Labor.

Prequalifying subcontractors on safety usually means collecting several kinds of evidence. OSHA inspection data is one of them. It is independent and public, but it has limits, and it works best next to what the subcontractor tells you.

What to ask for

  • A written safety programme and who is responsible for it on site.
  • Their experience modification rate (EMR), which their workers' compensation insurer calculates.
  • Their injury and illness records. OSHA says many employers with more than 10 employees must record work-related injuries and illnesses on Forms 300, 300A and 301, with some industries exempt.
  • Proof of insurance and any training records relevant to the work.
  • An explanation of any past OSHA citations, and what changed afterwards.

What OSHA data adds

The company does not write it. You can see whether OSHA has inspected a company, why, what it cited and what it assessed. That lets you compare what the company says with the public record. The contractor check guide shows how to look it up.

What it cannot tell you

  • Most workplaces are never inspected in a given year, so no record is not the same as a good record.
  • The same business can appear under several names. See name search pitfalls.
  • Recent inspections and citations may not be in the data yet.
  • It says little about the specific crew or project you are hiring for.

Things to look into, not treat as proof

  • Repeat citations for the same kind of hazard.
  • A Willful citation. See citation types explained.
  • A cluster of recent inspections after accidents.
  • A pattern that does not match what the company told you.

Why use more than one source

Each source has a blind spot. What the company tells you is selective. An insurer's modification rate is a single number. OSHA data covers only workplaces that were inspected. Put them side by side and the gaps show up. A company with a good story and no record is fine. A good story that conflicts with the record is worth a closer look.

Questions to ask when the record shows citations

  • What was the hazard, in the company's own words?
  • What changed afterwards, and who is responsible for it now?
  • Were the items corrected by the abatement date?
  • Was the citation contested or settled, and what was the outcome?
  • Is the same kind of work being done on my project?

Ask every subcontractor the same questions. A consistent process is fairer to the companies and easier to defend later. Write down the answers and the date.

A short checklist to copy

  1. Get the legal name, state and any trading names from the contract or W-9.
  2. Check the OSHA record under each name and state, and note the date.
  3. Ask for the safety programme, EMR and injury records.
  4. Ask about anything on the OSHA record that stands out.
  5. Record what you decided and why, and set a date to check again.

Common questions

How often should I recheck a subcontractor?

Before you sign, and again at renewal or when the scope changes. The record changes over time.

Is one citation a reason to reject a subcontractor?

Usually not on its own. Look at the type, the standard, how recent it is and whether there is a pattern. Then ask the company.
