Safety Definitions

The Definition of OSHA

OSHA is a federal agency within the U.S. Department of Labor responsible for setting and enforcing workplace safety and health standards.

What Is OSHA?

The Occupational Safety and Health Administration, a federal agency within the U.S. Department of Labor responsible for setting and enforcing workplace safety and health standards. Established under the Occupational Safety and Health Act of 1970, OSHA conducts inspections, issues citations, and provides compliance assistance to employers across most private-sector industries.

Example of OSHA Reporting

When a manufacturing plant reports an employee hospitalization, it must notify OSHA within 24 hours, and OSHA may follow up with an on-site inspection to determine what caused the incident.

Meaning of OSHA: Frequently Asked Questions

Does OSHA cover every workplace in the U.S.?

Most private-sector employers fall under federal OSHA or an OSHA-approved state plan, but there are exceptions — self-employed individuals, some family farms, and certain industries regulated by other federal agencies (like mining, covered by MSHA) aren't covered the same way. Public-sector coverage also varies by state.

What triggers an OSHA inspection?

Common triggers include employee complaints, reported fatalities or hospitalizations, referrals from other agencies, targeted programs for high-hazard industries, and follow-up inspections after a previous citation. OSHA also conducts random inspections in industries with historically high injury rates.

What's the difference between an OSHA standard and a recommendation?

Standards, published in 29 CFR, are legally enforceable requirements that can result in citations and penalties if violated. Recommendations or guidance documents — like many NIOSH publications — inform best practice but don't carry the same legal weight unless referenced within an enforceable standard.

How are OSHA penalties calculated?

Penalties depend on the violation type — other-than-serious, serious, willful, or repeat — and factors like the size of the business, its compliance history, and good-faith efforts to fix the issue. Willful and repeat violations carry substantially higher maximum penalties than first-time, non-willful ones.

Can employees request an OSHA inspection?

Yes. Employees can file a complaint with OSHA, including anonymously, if they believe a workplace hazard exists. OSHA reviews the complaint and determines whether it warrants an on-site inspection, a phone/fax investigation, or another form of follow-up with the employer.
