Do I need OSHA 10 in Missouri?

Only for some jobs. On construction of public works, Missouri's law makes contractors and subcontractors provide a ten-hour OSHA construction safety program to their on-site employees. A similar program the state labor department approves counts too. Employees who completed it before are excused.

How to get it done

  1. Step 1. Check two things. Is the work on public works, meaning fixed works built for public use or benefit or paid for wholly or partly with public funds? And are you an on-site employee, directly engaged in construction at the site, or working at a nearby or adjacent facility the contractor or subcontractor uses for the project? Missouri's statute says persons engaged solely in hauling materials, fuel or equipment to the site aren't deemed directly engaged.

  2. Step 2. Missouri's statute names a ten-hour OSHA construction safety program or a similar program the labor department approves. Before you sign up for an OSHA class, ask to see the trainer's current Authorized Trainer card.

  3. Step 3. OSHA says the 10-hour class is meant for workers, and the 30-hour class suits supervisors or workers with some safety responsibility. Missouri's statute sets sixty days from beginning work to finish the program.

  4. Step 4. A trainer has to issue your card within 90 days of the class. An employee found on a work site without proof of the course gets twenty days to produce it before being subject to removal, so keep the card or a copy with you.

Before you pay

Missouri's statute makes the contractor responsible for providing the program to its on-site employees, so ask your employer before you buy a class yourself.

Trainers work independently, and their fees and schedules vary. Compare more than one.

Questions

What does a contractor owe if workers go untrained?

The contractor forfeits two thousand five hundred dollars plus one hundred dollars for each employee, for each calendar day or portion of a day an employee works without the required training. The penalty does not begin to accrue until the sixty-day training period and the twenty days to produce proof have elapsed.

Are any projects outside the rule?

Yes. The section doesn't apply to work performed by public utilities under the Public Service Commission, their contractors, or work at facilities those utilities own or operate. It also doesn't apply to rail grade crossing improvement projects covered by a signed railroad agreement with the Missouri Department of Transportation or a department order.

Does a course other than OSHA 10 count?

It can. The labor department says approved alternatives include the OSHA 30-hour construction program, MSHA Part 46 and Part 48 New Miner Training, and PEC Core Compliance.

Does the card expire?

No. Missouri's labor department says OSHA completion cards for 10-hour construction programs do not expire.

Does OSHA itself require the class?

No. OSHA says its Outreach program is voluntary. Some states, municipalities, employers, unions and other groups require it, and the group that sets the rule decides what it accepts.

What to do next

Ask your contractor whether your job is public works, then pick a trainer from OSHA's Find a Trainer page. The rule is in Missouri's public works safety statute.
