Which Government Agency Is Charged With Workplace Safety in the USA?

When discussing workplace regulations in the United States, one of the most important questions many employers, workers, and safety professionals ask is: Which government agency is charged with workplace safety in the USA? This question matters because understanding who sets the laws, who enforces them, and who provides guidance helps organizations maintain compliance and protect their workforce.

In the United States, the primary agency responsible for workplace safety is the Occupational Safety and Health Administration (OSHA). However, OSHA does not work alone. Several federal and state-level bodies contribute to workplace health and safety, forming a nationwide system designed to protect more than 130 million workers across various industries.

Introduction to Workplace Safety Regulation in the USA

Workplace safety in the United States is governed by a network of federal and state agencies. However, the central figure in this ecosystem—and the agency you will encounter most frequently—is OSHA.

When asking “Which government agency is charged with workplace safety in the USA?”, OSHA provides the clearest answer, but the system extends further. OSHA sets standards, conducts inspections, enforces penalties, and ensures employers create safe environments.

The United States faces diverse industrial risks: construction accidents, chemical exposure, machine hazards, ergonomic issues, biological hazards, electrical systems, and psychological stress. To manage this complexity, the government established a robust regulatory system built on:

• The Occupational Safety and Health Act of 1970

• Federal OSHA

• State OSHA programs

• Complementary agencies like NIOSH and MSHA

• Strong employer and employee responsibilities

Together, these create one of the most comprehensive safety frameworks in the world.

The Primary Agency: Occupational Safety and Health Administration (OSHA)

What is OSHA?

OSHA, the Occupational Safety and Health Administration, is the federal agency within the U.S. Department of Labor responsible for ensuring safe working conditions. It is the direct answer to the question: Which government agency is charged with workplace safety in the USA?

Created under the Occupational Safety and Health Act of 1970, OSHA has the legal authority to:

• Create and enforce safety regulations

• Conduct workplace inspections

• Investigate accidents and complaints

• Issue fines and citations

• Provide training and education

• Encourage continuous workplace safety improvements

Why OSHA Was Created

Before the 1970s, workplace injuries and deaths were significantly higher. There were no unified national standards. Workers in mining, construction, manufacturing, and agriculture suffered high accident rates without consistent protection.

Congress responded by passing the OSH Act, establishing OSHA to create nationwide consistency and enforceable standards.

Legal Foundation: The Occupational Safety and Health Act of 1970 (OSH Act)

The OSH Act is the backbone of U.S. workplace safety.

Key Purposes of the OSH Act:

1. Assure safe and healthful working conditions

2. Ensure employers reduce known hazards

3. Authorize the enforcement of standards

4. Provide research and training

5. Empower employees with rights and protections

Under this law, OSHA develops and updates regulations, known as standards, which employers must follow.

Employer Duties Under the OSH Act

• Provide a workplace free from recognized hazards

• Comply with OSHA standards

• Train employees in a language they understand

• Maintain records of injuries and illnesses

• Provide PPE where required

• Report serious accidents within mandatory timelines

Employee Rights

• Access hazard information

• Receive safety training

• Request an OSHA inspection

• Report violations without retaliation

• Review workplace injury logs

This law gives OSHA broad power to protect American workers.

OSHA’s Core Functions and Responsibilities

Understanding OSHA’s duties explains why it is the main answer to Which government agency is charged with workplace safety in the USA?

1. Setting Standards

OSHA develops binding regulations on topics like:

• Hazard communication (chemical hazards)

• Fall protection

• Machine guarding

• Bloodborne pathogens

• Respiratory protection

• Electrical safety

• Construction site requirements

• Confined space entry

These standards have legal force.

2. Conducting Inspections

OSHA conducts inspections both scheduled and unannounced. Priority is given to:

• Imminent danger situations

• Fatalities and severe injuries

• Employee complaints

• High-risk industries

• Follow-up cases

3. Accident Investigation

OSHA investigates:

• Fatalities

• Amputations

• Hospitalizations

• Catastrophic events

• Chemical releases

Investigations determine root causes and whether violations occurred.

4. Issuing Citations and Penalties

OSHA has strong enforcement authority. It can issue:

• Serious citations

• Willful citations

• Repeat violations

• Failure-to-abate notices

Fines can reach hundreds of thousands of dollars depending on the severity.

5. Training and Education

Through programs like the OSHA Training Institute (OTI) and outreach trainer programs, OSHA educates millions of workers annually.

6. Outreach and Consultation Programs

OSHA offers free on-site consultation for small and medium-sized businesses—non-enforcement based—to help them comply voluntarily.

What Workplaces Fall Under OSHA’s Authority?

OSHA covers most private-sector workplaces across all states, including:

• Construction

• Manufacturing

• Warehousing

• Healthcare

• Transportation

• Waste management

• Retail and hospitality

• Chemical and industrial facilities

However, some industries fall under separate agencies (explained later).

State OSHA Programs (State Plans)

Although federal OSHA is the primary regulator, the OSH Act allows states to run their own OSHA-approved programs.

There are 22 state plans covering:

• Private-sector workplaces

• Public-sector employees

Another 6 states cover only public-sector workers.

State OSHA plans must be “at least as effective as OSHA,” but many adopt even stronger standards (e.g., California’s Cal/OSHA).

Examples of State-Plan OSHA Agencies:

• Cal/OSHA – California

• MIOSHA – Michigan

• IOSH – Indiana

• ADOSH – Arizona

• WashOSH – Washington

• Nevada OSHA

State plans play a major role in answering Which government agency is charged with workplace safety in the USA, because in state-plan jurisdictions, the state OSHA carries out enforcement.

Other Federal Agencies Involved in Workplace Safety

While OSHA is the primary authority, several other agencies also regulate safety based on industry and hazard type.

1. NIOSH (National Institute for Occupational Safety and Health)

NIOSH is part of the Centers for Disease Control (CDC).

Role of NIOSH:

• Conducts research

• Develops recommended exposure limits

• Provides technical guidance

• Studies workplace diseases

• Enhances safety technologies

NIOSH and OSHA work together but have separate missions—NIOSH is research-focused.

2. MSHA (Mine Safety and Health Administration)

MSHA regulates:

• Mines

• Quarries

• Mineral processing plants

Mining is not under OSHA jurisdiction—MSHA has its own laws and inspectors.

3. EPA (Environmental Protection Agency)

EPA oversees:

• Chemical regulations

• Environmental hazards

• Hazardous waste (RCRA)

• Toxic substances

• Clean Air Act compliance

EPA rules sometimes overlap with OSHA but focus on environmental impact rather than worker safety.

4. DOT (Department of Transportation)

DOT enforces:

• Hazardous materials transportation

• Commercial motor vehicle safety

• Pipeline safety

5. USDA and FDA

These agencies oversee safety in:

• Food processing

• Agricultural operations

• Meat and poultry plants

6. Nuclear Regulatory Commission (NRC)

Regulates nuclear facility safety.

Examples of How OSHA Protects Workers Daily

To illustrate OSHA’s impact, here are real-world examples:

Example 1: Construction Fall Hazard

A worker falls from scaffolding due to improper guardrails.
OSHA investigates, cites the employer, and requires fall protection training.

Example 2: Chemical Exposure in Manufacturing

Workers report breathing problems.
OSHA tests air samples and requires ventilation upgrades.

Example 3: Warehouse Forklift Accident

After a forklift flips due to speeding, OSHA mandates operator certification and layout changes.

Example 4: Healthcare Bloodborne Pathogens

Hospitals must follow OSHA’s bloodborne pathogens standard, protecting nurses and medical staff.

These examples show OSHA’s presence across various industries.
