Most one-person mobile mechanics never think about OSHA, and for a sole operator with no employees that’s mostly fine. The day you hire a helper or a technician, it changes. Here’s what applies, from OSHA’s own rules.

Who OSHA covers

OSHA protects employees. OSHA’s own materials say the OSH Act does not cover self-employed people (OSHA, We Can Help, PDF). A sole proprietor working alone isn’t covered as an employer. Once you have even one employee, you’re an employer under the Act. Some states run their own OSHA-approved “State Plans” with their own rules.

That doesn’t make the hazards go away when you work alone: jacks, lifts, chemicals, hot fluids and traffic in a driveway. It only means no inspector. Your insurance and your body still care.

Injury records: the 10-employee exemption

Under 29 CFR 1904.1, if your company had 10 or fewer employees at all times during the last calendar year, you don’t need to keep OSHA injury and illness records (the 300, 300A and 301 forms), unless OSHA or BLS tells you in writing to do so (eCFR, 29 CFR 1904.1).

Severe injury reporting: applies to everyone with employees

Even small employers must report (OSHA, Recordkeeping):

Hazard Communication: the rule that hits repair shops

Repair work uses hazardous chemicals every day: brake cleaner, solvents, fuel, refrigerants and coolant. Under OSHA’s Hazard Communication Standard (29 CFR 1910.1200), an employer must have (eCFR, 1910.1200):

For a mobile operation with a helper: keep SDSs on a tablet or in a binder in the van, keep labels on every spray bottle you refill, and document the training you give. OSHA’s Hazard Communication page has free SDS and label QuickCards.

2026 penalty amounts

OSHA’s maximum penalties, as adjusted for inflation and assessable after January 15, 2026 (OSHA, Penalties):

ViolationMaximum
Serious / other-than-serious / posting$16,550 per violation
Failure to abate$16,550 per day past the abatement date
Willful or repeated$165,514 per violation

State Plans must set maximum penalties at least as effective as federal OSHA’s.

Free help: On-Site Consultation

OSHA’s On-Site Consultation Program offers no-cost, confidential consultations, mainly for small businesses, run by state agencies or universities and separate from enforcement (OSHA, Consultation). For a small shop about to hire, it’s the cheapest way to find problems before an inspector or an injury does.

Before you hire: checklist

  1. Workers’ comp: check your state’s rules before the first paycheck. See workers’ comp for auto repair shops.
  2. W-2 vs 1099: see hiring your first technician.
  3. HazCom program, SDS binder, labels and training records.
  4. Equipment: inspect jacks, stands and lifts, and train on them.
  5. Know the 8- and 24-hour reporting rules, and post OSHA’s required workplace poster.
  6. Budget it: safety gear, training time and insurance are overhead. Add them to the labor rate & break-even calculator.
