OSHA Small Business Exemption: Who Qualifies?

A roofing contractor in Phoenix with eight employees once told me, straight-faced: "OSHA only goes after the big guys." Six months later he was staring at a $33,000 citation for HazCom violations — no SDS on file, no training records, zero documentation. His company almost didn't survive it.

There's a persistent myth in small business circles that OSHA doesn't apply to companies under a certain size. "We only have five employees — OSHA can't touch us." I hear variations of this constantly, and it gets business owners into trouble every time.

The truth is more nuanced. OSHA does have limited exemptions for small employers, but they're narrower than most people think. And they definitely don't exempt you from chemical safety obligations.

What Is the OSHA Small Business Exemption?

The OSHA small business exemption primarily applies to recordkeeping, not to safety standards themselves. Businesses with 10 or fewer employees at all times during the previous calendar year are exempt from routine OSHA injury and illness recordkeeping (OSHA 300 logs). They are also partially exempt from programmed OSHA inspections under the agency's Site-Specific Targeting plan. However, all OSHA safety and health standards — including the Hazard Communication Standard governing SDS — still apply in full regardless of company size.

What the Exemption Does NOT Cover

This is the part that catches small business owners off guard. The recordkeeping exemption does not excuse you from any actual safety standard. You still must:

1. Comply with all OSHA safety and health standards, including HazCom
2. Maintain Safety Data Sheets for every hazardous chemical in the workplace
3. Train employees on chemical hazards before first exposure
4. Provide required PPE at no cost to employees
5. Report any workplace fatality within 8 hours
6. Report any hospitalization, amputation, or eye loss within 24 hours
7. Allow OSHA entry for complaint-driven or referral-based inspections

The 10-Employee Count: How It Actually Works

The count includes all employees across all locations, not per location. Part-time workers count. Temporary workers from staffing agencies generally don't count toward your total, but you're still responsible for their safety while they're on your site. And the count is based on the peak employment during the previous year — if you hit 11 employees for even one pay period, you lose the exemption for the following year.

Seasonal businesses get tripped up here regularly. A landscaping company with 6 year-round employees who hires 5 seasonal workers every summer has 11 employees and doesn't qualify for the recordkeeping exemption. They still need full OSHA compliance for small business.

Can OSHA Still Inspect a Small Business?

Absolutely. The exemption reduces your chance of a programmed inspection (the random ones based on industry risk). But OSHA can and will inspect any business, regardless of size, in response to an employee complaint, a referral from another agency, a reported injury or fatality, or an imminent danger situation. An employee who reports unsafe chemical handling can trigger an inspection at a company with three people.

And here's the part that really stings — penalties aren't reduced based on company size alone. OSHA does consider business size as one factor in penalty adjustment, but a small business can still face the same per-violation maximums. A missing SDS costs the same whether you have 5 employees or 500.

The OSHA Consultation Program: Your Best Resource

If you're a small business concerned about compliance, OSHA's free On-Site Consultation Program is hands-down the most underappreciated government resource out there. Available in every state, it provides free, confidential safety assessments. The consultant identifies hazards, suggests corrections, and helps you build a safety program — all without triggering enforcement action. The only exception is if they find imminent danger to employees.

Request a consultation at your state's OSHA consultation program office. They'll walk your facility, review your SDS system, check your chemical inventory, and help you close gaps before an actual inspector finds them. It's one of the most underused resources available to small employers.

Frequently Asked Questions

Do businesses with fewer than 10 employees need SDS?

Yes. The 10-employee exemption only applies to OSHA recordkeeping (injury and illness logs). The Hazard Communication Standard, which requires SDS for all hazardous chemicals, applies to every employer with even one employee who may be exposed to hazardous chemicals.

Are sole proprietors subject to OSHA?

Self-employed individuals with no employees are not covered by OSHA. However, the moment you hire even one employee — including part-time workers — all applicable OSHA standards apply, including maintaining SDS for hazardous chemicals in the workplace.

Does the small business exemption apply to all industries?

The recordkeeping exemption has two criteria: size (10 or fewer employees) and industry classification. Some industries are exempt from routine recordkeeping regardless of size, based on their NAICS code and historical injury rates. However, certain high-hazard industries are never exempt from recordkeeping, even under 10 employees. Check OSHA's current exemption list for your specific NAICS code.
