OSHA Compliance Fundamentals

The Occupational Safety and Health Administration (OSHA) sets and enforces workplace safety standards across the United States. Whether you work in construction, manufacturing, warehousing, or any other industry, understanding OSHA requirements protects you and keeps your employer in compliance. This guide provides a comprehensive overview of OSHA's structure, standards, enforcement procedures, recordkeeping requirements, and the violations inspectors cite most often.

The History and Mission of OSHA

Before OSHA was created, workplace safety was largely left to individual states, and enforcement was inconsistent. In 1970, an estimated 14,000 workers died on the job each year. Congress passed the Occupational Safety and Health Act on December 29, 1970, and President Nixon signed it into law. OSHA began operations on April 28, 1971, a date now observed as Workers' Memorial Day.

Since OSHA's creation, workplace fatality rates have decreased by more than 60%, and occupational injury and illness rates have dropped by approximately 40%. The agency's mission remains: to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance.

OSHA's Organizational Structure

OSHA operates under the U.S. Department of Labor. Its structure includes:

• National Office - Sets policy, develops standards, and coordinates enforcement nationwide.
• 10 Regional Offices - Oversee enforcement within their geographic regions.
• 85+ Area Offices - Conduct inspections and handle complaints at the local level.
• State Plans - 22 states and territories operate their own OSHA-approved safety and health programs that must be "at least as effective" as federal OSHA. Examples include Cal/OSHA (California), MIOSHA (Michigan), and TOSHA (Tennessee). If you work in a state-plan state, your employer must comply with that state's standards, which may be more stringent than federal standards.

The General Duty Clause

Section 5(a)(1) of the OSH Act is known as the General Duty Clause. It requires employers to provide a workplace "free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees." OSHA uses the General Duty Clause to cite employers for hazards that are not covered by a specific standard. For a General Duty Clause citation, OSHA must prove:

1. A hazard existed in the workplace
2. The hazard was recognized by the employer or the industry
3. The hazard was causing or was likely to cause death or serious physical harm
4. A feasible means existed to eliminate or materially reduce the hazard

The General Duty Clause has been used for hazards such as workplace violence, heat illness (before the proposed heat standard), ergonomic hazards, and combustible dust.

OSHA Standards - Structure and Key Standards

OSHA standards are published in the Code of Federal Regulations (CFR), Title 29:

General Industry (29 CFR 1910)

These standards apply to most workplaces except construction, maritime, and agriculture. Key subparts include:

• Subpart D - Walking-Working Surfaces (1910.21-30): Requires employers to keep floors clean and dry, provide guardrails on platforms, and protect floor openings.
• Subpart G - Occupational Health and Environmental Control (1910.94-98): Covers ventilation, noise exposure (1910.95), and ionizing radiation.

• Subpart CC - Cranes and Derricks (1926.1400-1442): Comprehensive crane safety requirements.

Employer Responsibilities

Under the OSH Act, every employer must:

• Provide a workplace free from recognized hazards (General Duty Clause)
• Comply with all applicable OSHA standards
• Provide required PPE at no cost to workers
• Post the OSHA "It's the Law" poster (OSHA 3165) where workers can see it
• Report any workplace fatality within 8 hours
• Report any in-patient hospitalization, amputation, or loss of an eye within 24 hours
• Keep accurate records of work-related injuries and illnesses (unless exempt)
• Provide access to medical and exposure records to employees
• Not retaliate against workers who report safety concerns
• Post OSHA citations at or near the location of the violation for at least 3 working days or until the hazard is abated, whichever is longer
• Provide required training in a language and vocabulary workers understand

Worker Rights Under OSHA

As a worker, you have the right to:

• File a complaint - Report unsafe conditions to OSHA by phone (1-800-321-OSHA), online, by fax, or by mail. Complaints can be filed confidentially.
• Request an inspection - If you believe serious hazards exist or your employer is not following standards.
• Participate in inspections - A worker representative can accompany the OSHA inspector during the walk-around.
• Access records - Review the OSHA 300 Log, your exposure monitoring results, and your medical records.
• Receive training - Training about workplace hazards in a language you understand.
• Refuse dangerous work - Under very specific conditions (imminent danger, no time for OSHA to respond, you have asked the employer to correct the hazard).
• Be free from retaliation - Section 11(c) protects you from firing, demotion, transfer, or any adverse action for exercising your safety rights. You have 30 days to file a retaliation complaint.

OSHA Recordkeeping (29 CFR 1904)

Who Must Keep Records

All employers with more than 10 employees must maintain OSHA injury and illness records, unless they are in a partially exempt low-hazard industry (such as retail clothing, finance, or insurance). However, all employers must report fatalities and severe injuries regardless of size or industry.

The Three OSHA Recordkeeping Forms

OSHA 300 Log (Log of Work-Related Injuries and Illnesses):
A running log maintained throughout the calendar year documenting every recordable case. For each case, the log records:

• Employee name, job title, and date of injury/illness
• Description of what happened
• Classification (death, days away from work, restricted duty, transfer, or other recordable case)
• Number of days away from work or restricted days

OSHA 301 Form (Injury and Illness Incident Report):
A detailed report completed for each recordable case within 7 calendar days. Includes specifics about how the injury occurred, what the employee was doing, and what object or substance harmed them. Workers' compensation first report of injury forms may be used as a substitute if they contain equivalent information.

OSHA 300A Summary:
An annual summary of the 300 Log, certified by a company executive. Must be posted in a visible location from February 1 through April 30 of the following year. Employers with 250+ employees (or 20-249 employees in certain high-hazard industries) must also electronically submit 300A data to OSHA annually.

What Makes a Case Recordable

A work-related injury or illness is recordable if it results in any of the following:

• Death
• Days away from work
• Restricted work or transfer to another job
• Medical treatment beyond first aid
• Loss of consciousness
• Significant injury or illness diagnosed by a physician or licensed healthcare professional (e.g., cancer, fracture, punctured eardrum)

First Aid vs. Medical Treatment

Understanding the distinction is critical because first-aid-only cases are NOT recordable. OSHA defines first aid as:

• Non-prescription medications at nonprescription strength
• Tetanus immunizations
• Cleaning, flushing, or soaking wounds on the surface of the skin
• Wound coverings (bandages, butterfly bandages, Steri-Strips)
• Hot or cold therapy
• Non-rigid means of support (elastic bandages, wraps)
• Drilling a fingernail or toenail to relieve pressure
• Eye patches
• Removing foreign bodies from the eye with irrigation or a cotton swab
• Removing splinters with tweezers
• Finger guards
• Massages
• Drinking fluids for relief of heat stress

Any treatment beyond this list is "medical treatment" and makes the case recordable.

OSHA Inspections - What to Expect

Inspection Priorities

OSHA prioritizes inspections in this order:

1. Imminent danger - Situations where workers face immediate risk of death or serious harm
2. Fatalities and catastrophes - Incidents resulting in death or hospitalization of 3+ workers
3. Worker complaints and referrals - Complaints filed by workers, referrals from other agencies
4. Programmed inspections - Targeted inspections of high-hazard industries based on injury data
5. Follow-up inspections - Verification that previously cited hazards have been corrected

The Inspection Process

Credentials and Opening Conference:
The compliance safety and health officer (CSHO) will present official credentials. You have the right to verify credentials by calling the local OSHA office. The CSHO explains the purpose, scope, and procedures of the inspection during an opening conference.

Walk-Around Inspection:
The CSHO tours the workplace, observing conditions, taking photographs, collecting samples, and reviewing records. An employer representative and a worker representative have the right to accompany the CSHO. The inspector may interview workers privately - you cannot be disciplined for what you tell them.

Closing Conference:
The CSHO discusses preliminary findings, possible violations, and the employer's right to contest citations. The employer has the opportunity to provide additional information.

Citations and Penalties (2024 Penalty Amounts)

• Other-Than-Serious - A violation that has a direct relationship to job safety but would not likely result in death or serious harm. Maximum penalty: $16,131 per violation.
• Serious - A violation where the hazard could cause death or serious physical harm and the employer knew or should have known about it. Maximum penalty: $16,131 per violation.
• Willful - A violation the employer intentionally and knowingly committed, or committed with plain indifference to the law. Maximum penalty: $161,323 per violation. Minimum penalty: $11,524.
• Repeat - A violation of the same standard within the past 5 years. Maximum penalty: $161,323 per violation.
• Failure to Abate - Not correcting a previously cited violation by the abatement date. Maximum penalty: $16,131 per day beyond the abatement date.

Contesting Citations

Employers have 15 working days from receipt of a citation to file a Notice of Contest with the OSHA Area Director. If not contested, the citation becomes a final order not subject to review.

OSHA's Top 10 Most Cited Violations

Year after year, the same violations appear on OSHA's most-cited list. For fiscal year 2023:

1. Fall Protection - General Requirements (1926.501) - 7,271 violations
2. Hazard Communication (1910.1200) - 3,213 violations
3. Ladders (1926.1053) - 2,978 violations
4. Scaffolding (1926.451) - 2,859 violations
5. Powered Industrial Trucks (1910.178) - 2,561 violations
6. Lockout/Tagout (1910.147) - 2,554 violations
7. Respiratory Protection (1910.134) - 2,481 violations
8. Fall Protection - Training (1926.503) - 2,112 violations
9. Eye and Face Protection (1926.102) - 2,074 violations
10. Machine Guarding (1910.212) - 1,644 violations

Understanding these common violations helps you recognize hazards that inspectors look for on every visit and that cause the most injuries.

OSHA Training Requirements

Many OSHA standards include specific training requirements. Some of the most common include:

• Hazard Communication (1910.1200) - Training on chemical hazards in the work area
• Lockout/Tagout (1910.147) - Training for authorized and affected employees
• Confined Space Entry (1910.146) - Training for entrants, attendants, and supervisors
• Respiratory Protection (1910.134) - Training on respirator use, limitations, and maintenance
• Bloodborne Pathogens (1910.1030) - Annual training for exposed workers
• Powered Industrial Trucks (1910.178) - Operator training and evaluation every 3 years
• Fall Protection (1926.503) - Training on fall hazards and protection systems
• Electrical Safety (1910.332) - Training for employees who face electrical hazards

Training must be provided before workers are exposed to hazards, when hazards change, and when workers are observed not following procedures. Training must be in a language and vocabulary workers understand.

Real-World OSHA Enforcement Examples

Understanding real enforcement actions reinforces why compliance matters:

Case: Trench Collapse (2022) - A construction company was cited after a worker was killed in a trench collapse. The trench was 9 feet deep with no protective system (shoring, shielding, or sloping). OSHA issued willful citations with proposed penalties of $405,000. OSHA standard 1926.652 requires protective systems for trenches 5 feet or deeper.

Case: Machine Guarding Failure (2023) - A manufacturing worker suffered an amputation when their hand was pulled into an unguarded power press. The employer had removed the point-of-operation guard to increase production speed. OSHA issued willful and serious citations totaling $312,000. The guard had been in place for years before being removed.

Case: Fall Protection (2023) - A roofing contractor was cited after a worker fell 22 feet from a roof edge with no fall protection. The worker survived with serious injuries. The same contractor had been cited for identical violations twice in the previous three years. As a repeat violation, penalties exceeded $300,000.

These cases share a common thread: the hazards were well-known, the standards were clear, and the controls were straightforward. Every one of these injuries was preventable.
