Top 10 Most Cited OSHA Violations: A Data-Driven Compliance Guide
An analysis of the most frequently cited OSHA standards across 2,336,195 inspected facilities, 11,532,943 total violations, and $5.8 billion in assessed penalties — with actionable strategies to keep your workplace compliant.
Every year, the Occupational Safety and Health Administration (OSHA) publishes its list of the most frequently cited workplace safety standards. These citations represent the most persistent, widespread hazards that American employers fail to address — and they consistently result in worker injuries, fatalities, and billions of dollars in penalties.
This guide goes beyond a simple list. Using SVEP Navigator’s database of 2.3 million inspected facilities and 11.5 million violation records, we analyze the historical citation data for each of the top 10 standards, explain what they require, identify common citation scenarios, and provide clear compliance strategies. Whether you’re a safety manager, compliance officer, or business owner, understanding these standards is essential to protecting your workers and avoiding costly penalties.

Violation Type Distribution
Not all citations carry the same weight. OSHA classifies violations into five types, each reflecting the severity and intent behind the hazard. Understanding these classifications helps employers gauge their legal and financial exposure.
Hazard Communication (HazCom)
What it requires: The Hazard Communication Standard (HazCom) mandates that employers develop and maintain a comprehensive written hazard communication program. This program must include a complete inventory of hazardous chemicals present in the workplace, properly labeled containers with GHS-compliant labels, safety data sheets (SDS) accessible to all employees, and effective employee training on chemical hazards.
Why it’s #1: HazCom appears in virtually every industry — from manufacturing plants handling industrial solvents to retail stores stocking cleaning products. The standard’s broad applicability means that even small businesses with common cleaning supplies can be cited if they lack a written program or fail to maintain accessible safety data sheets. Its 539,927 citations span 261,664 unique facilities, making it the single most pervasive compliance failure in OSHA’s history.
Common citation scenarios:
- No written hazard communication program on file
- Missing or outdated safety data sheets (SDS) for chemicals on site
- Secondary containers (spray bottles, buckets) lacking hazard labels
- Employees never trained or not retrained when new chemicals are introduced
- Chemical inventory list not updated to reflect current stock
How to comply: Maintain a written HazCom program, keep an up-to-date chemical inventory, ensure every container is labeled with GHS-compliant labeling, make SDS available within seconds (digital binders work), and conduct initial and recurring training for all workers who handle or may be exposed to hazardous chemicals.
View 29 CFR 1910.1200 Enforcement Data →Scaffolding — General Requirements
What it requires: This construction industry standard establishes safety requirements for scaffolds used in the workplace. Each scaffold and scaffold component must support its own weight and at least four times the maximum intended load without failure. The standard covers scaffold erection, platform construction, access requirements, fall protection on scaffolds, and specific rules for different scaffold types (supported, suspended, mobile, etc.).
Why it matters: Scaffolding collapses and falls from scaffold platforms are among the most lethal construction hazards. With $277 million in assessed penalties, scaffold violations carry some of the highest per-citation penalty amounts in the construction sector. Improper scaffolding endangers not only the workers on the scaffold but also those working below.
Common citation scenarios:
- Scaffold platforms not fully planked or decked, leaving gaps workers can fall through
- No guardrails, midrails, or toeboards on scaffold platforms above 10 feet
- Scaffolds erected on unstable bases or without proper mudsills and base plates
- Workers accessing scaffolds via cross-braces instead of proper ladders or stairways
- Scaffold not inspected by a competent person before each work shift
How to comply: Ensure all scaffolds are designed and erected under the supervision of a competent person, install guardrails and toeboards on all open sides and ends at 10 feet or more, provide proper access (ladders, stair towers), and conduct daily inspections before use. Train all scaffold users and erectors on hazard recognition.
View 29 CFR 1926.0451 Enforcement Data →Fall Protection — Duty to Have Fall Protection
What it requires: The Fall Protection standard requires construction employers to provide fall protection systems for employees working at heights of 6 feet or more above a lower level. Acceptable fall protection includes guardrail systems, safety net systems, and personal fall arrest systems (harnesses). The standard also covers protection from falling into holes, open-sided floors, and dangerous equipment.
Why it matters: Falls are the leading cause of death in the construction industry, accounting for roughly one-third of all construction fatalities each year. Despite ranking third in citation count, 29 CFR 1926.0501 carries the highest total penalties of any OSHA standard at $576 million — reflecting the severity of injuries and deaths that result from fall protection failures. The 248,949 facilities cited represent a massive share of the construction sector.
Common citation scenarios:
- Workers on roofs, open floors, or elevated platforms without any fall protection
- Unprotected wall openings, floor holes, or skylight openings
- Workers on leading edges during steel erection or concrete formwork without harnesses
- Inadequate or improperly anchored personal fall arrest systems
- No fall protection plan for work activities where conventional systems are infeasible
How to comply: Conduct a fall hazard assessment before work begins at any elevated location. Install guardrails on all unprotected sides and edges. For tasks where guardrails are infeasible, provide properly anchored personal fall arrest systems with full-body harnesses. Cover or guard all floor openings. Train all employees on fall hazard recognition and proper use of equipment.
View 29 CFR 1926.0501 Enforcement Data →Mechanical Power-Transmission Apparatus
What it requires: This standard mandates the guarding of mechanical power-transmission components — flywheels, pulleys, belts, chains, sprockets, shafts, couplings, and gears. Any rotating or moving part that could cause injury through contact must be enclosed or guarded to prevent worker entanglement, amputation, or death.
Why it matters: Power-transmission hazards exist in every manufacturing, processing, and industrial facility that uses belt-driven or chain-driven equipment. These are “silent” hazards — equipment that has operated safely for years can cause catastrophic amputations in a fraction of a second if a worker’s clothing, hair, or limb contacts an unguarded rotating component. The 247,855 citations reflect how commonly these guards are removed and never replaced.
Common citation scenarios:
- Exposed belts, pulleys, or chains within 7 feet of a walking or working surface
- Guards removed for maintenance and never reinstalled
- Homemade guards that don’t fully enclose the hazard or have gaps large enough for fingers
- Horizontal shafting or projecting shaft ends left unguarded
How to comply: Audit all power-transmission equipment for exposed moving parts. Install manufacturer-recommended guards or custom-fabricated enclosures that fully cover hazards. Implement a guard removal/replacement policy tied to your lockout/tagout procedures. Inspect guards regularly for damage, looseness, or gaps.
View 29 CFR 1910.0219 Enforcement Data →General Requirements for All Machines (Machine Guarding)
What it requires: Machine guarding is one of OSHA’s broadest standards. It requires that one or more methods of guarding be provided to protect operators and other workers from hazards created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks. Guards must be affixed to the machine where possible and must not create additional hazards (sharp edges, pinch points).
Why it matters: Machine-related amputations remain one of the most common severe workplace injuries in the United States, with OSHA’s Severe Injury Reporting program tracking thousands of amputation events each year. At $187 million in total penalties across 182,185 facilities, this standard carries significant financial consequences — particularly when violations are classified as Repeat or Willful after a worker is injured.
Common citation scenarios:
- No point-of-operation guard on power presses, saws, drills, or grinders
- Guards removed to speed up production or clear jams, then never replaced
- Guards that don’t prevent the operator from reaching into the danger zone
- Anchoring machines to prevent walking or movement during operation not addressed
- Lack of blade guards on table saws, band saws, and miter saws
How to comply: Perform a machine hazard assessment for every piece of equipment in your facility. Install appropriate guards (barrier guards, two-hand tripping devices, electronic safety devices) at all points of operation. Ensure guards cannot be easily bypassed and implement procedures that require re-installation after maintenance or cleaning. Train workers never to operate unguarded machinery.
View 29 CFR 1910.0212 Enforcement Data →Respiratory Protection
What it requires: When engineering controls alone cannot reduce airborne contaminants to safe levels, employers must establish a written respiratory protection program. The program must include worksite-specific procedures, respirator selection based on hazard assessment, medical evaluations for each employee who wears a respirator, annual fit testing, training, and proper maintenance and storage of respirators.
Why it matters: Occupational lung diseases — including silicosis, asbestosis, and chemical pneumonitis — are among the most devastating and irreversible workplace health conditions. With 233,007 citations across 109,071 facilities, respiratory violations are widespread in manufacturing, construction, healthcare, and any industry involving dust, fumes, gases, or vapors. Inadequate respiratory protection can lead to chronic illness that manifests years after exposure.
Common citation scenarios:
- No written respiratory protection program despite workers wearing respirators
- Workers using respirators without medical clearance evaluation
- Failure to conduct annual quantitative or qualitative fit testing
- Wrong respirator type for the specific contaminant (e.g., dust mask for chemical vapors)
- Voluntary use of respirators without providing Appendix D information
How to comply: Develop a written respiratory protection program with a designated program administrator. Conduct exposure assessments to select the proper respirator type and cartridge. Arrange medical evaluations before initial respirator use. Perform annual fit testing using OSHA-accepted protocols. Train employees on proper donning, doffing, user seal checks, and cartridge change-out schedules.
View 29 CFR 1910.0134 Enforcement Data →Wiring Methods, Components, and Equipment
What it requires: This electrical safety standard covers the installation and maintenance of wiring methods, components, and equipment for general industry. It addresses junction boxes, conduit, cable trays, grounding, overcurrent protection, and the proper use and condition of flexible cords and cables. All electrical installations must comply with the National Electrical Code (NEC) standards.
Why it matters: Electrical hazards cause approximately 160 workplace fatalities and thousands of injuries every year in the United States. Faulty wiring, overloaded circuits, and improperly maintained electrical equipment create risks of electrocution, arc flash, and fire. The 222,174 citations across 145,380 facilities demonstrate that electrical safety deficiencies are common in virtually every type of workplace — from offices and retail stores to heavy manufacturing plants.
Common citation scenarios:
- Open junction boxes with exposed wiring or missing covers
- Flexible cords used as permanent wiring (extension cords run through walls, ceilings, or under carpets)
- Electrical panels with missing knockouts, breaker slots open without blanks
- Damaged insulation on conductors, exposing live wires
- Improper grounding of equipment or circuits
How to comply: Conduct regular electrical inspections of all wiring, panels, junction boxes, and equipment. Replace damaged cords immediately. Ensure all junction boxes have proper covers. Do not use flexible cords as a substitute for fixed wiring. Maintain clear access to all electrical panels (36-inch clearance). Have a licensed electrician address any NEC non-compliance issues.
View 29 CFR 1910.0305 Enforcement Data →Portable Fire Extinguishers
What it requires: Employers who provide portable fire extinguishers must mount, locate, and identify them so they are readily accessible. Extinguishers must be maintained in a fully charged and operable condition, inspected monthly by visual check, and undergo annual professional maintenance. Employers must also provide employee training on the proper use of fire extinguishers upon initial assignment and at least annually thereafter.
Why it matters: While the per-citation penalty for fire extinguisher violations is relatively low at $21 million total, the safety implications are enormous. A fire extinguisher that is uncharged, blocked, missing, or that employees don’t know how to use can be the difference between a minor incident and a catastrophic workplace fire. With 202,800 citations at 144,165 facilities, this is one of the most common “low-hanging fruit” citations inspectors issue.
Common citation scenarios:
- Fire extinguishers not mounted or accessible (blocked by inventory, pallets, or equipment)
- No monthly visual inspection records or annual maintenance tags
- Extinguishers with expired inspections or discharged pressure gauges
- Travel distance to nearest extinguisher exceeds 50 feet (Class A) or 75 feet (Class B)
- Employees not trained on when and how to use a fire extinguisher
How to comply: Mount fire extinguishers on brackets or in cabinets at appropriate heights, spaced per travel distance requirements. Assign someone to perform monthly visual inspections (check gauge, seal, physical condition) and document them with tags or logs. Schedule annual professional maintenance. Conduct annual hands-on fire extinguisher training for all employees.
View 29 CFR 1910.0157 Enforcement Data →Abrasive Wheel Machinery
What it requires: This standard governs the use, mounting, and guarding of abrasive wheels (grinding wheels, cutting wheels, wire brush wheels) on bench grinders, pedestal grinders, portable grinders, and similar equipment. Requirements include proper wheel guards (exposing no more than 90 degrees of the grinding surface for bench/pedestal grinders), work rests adjusted to within 1/8 inch of the wheel, tongue guards within 1/4 inch, ring testing of vitrified wheels before mounting, and proper wheel speed matching.
Why it matters: Grinding wheel failures can propel fragments at speeds exceeding 10,000 feet per minute — fast enough to penetrate the human body. Improperly guarded grinders also expose workers to flying sparks, dust, and wheel fragments on a daily basis. The 191,526 citations reflect how ubiquitous grinding equipment is in manufacturing, fabrication, automotive repair, and maintenance shops, and how frequently the guards and rests fall out of adjustment.
Common citation scenarios:
- Work rest (tool rest) adjusted more than 1/8 inch from the abrasive wheel face
- Tongue guard exceeding 1/4 inch from the wheel
- Missing or damaged peripheral guard on bench or pedestal grinder
- Workers not performing ring test before mounting vitrified wheels
- Using a grinding wheel rated for a lower RPM than the grinder’s rated speed
How to comply: Adjust work rests to within 1/8 inch and tongue guards to within 1/4 inch of the wheel — readjust every time the wheel wears down. Never exceed the wheel’s maximum rated RPM. Ring-test all new vitrified wheels before mounting. Ensure guards are securely attached and cover the required arc. Train all grinder operators on setup, adjustment, and hazard recognition.
View 29 CFR 1910.0215 Enforcement Data →The Control of Hazardous Energy (Lockout/Tagout)
What it requires: The Lockout/Tagout (LOTO) standard requires employers to establish a written energy control program with machine-specific lockout/tagout procedures for every piece of equipment that could unexpectedly start up, release stored energy, or energize during maintenance or servicing. The program must include employee training, periodic inspections of energy control procedures (at least annually), and provide standardized lockout/tagout devices for each authorized employee.
Why it matters: Failure to properly control hazardous energy during maintenance causes an estimated 120 fatalities and 50,000 injuries per year in the United States, according to OSHA. With $212 million in total penalties — the third-highest of any standard — LOTO violations are treated with extreme severity, particularly after an incident. When a worker is killed or seriously injured because lockout/tagout was not performed, employers frequently face Willful violation classifications with penalties exceeding $100,000 per citation.
Common citation scenarios:
- No written energy control (lockout/tagout) program or procedures
- Machine-specific procedures not developed for individual pieces of equipment
- Employees not trained on the purpose and function of the energy control program
- No periodic inspection (annual audit) of lockout/tagout procedures
- Using tagout alone when lockout is feasible
- Authorized employees not provided with individual locks and keys
How to comply: Develop a comprehensive written LOTO program with machine-specific energy control procedures for every serviced or maintained machine. Provide standardized locks, tags, and hasps to every authorized employee. Train authorized employees (those who lock out) and affected employees (those who work in the area) on their respective roles. Conduct annual inspections of each procedure using a qualified inspector who was not involved in the procedure being reviewed.

Key Takeaways
Several critical patterns emerge from this data:
Citations don’t always correlate with penalties. Hazard Communication leads in raw citations (539,927), but Fall Protection leads in total penalties ($576 million) with far fewer citations. This reflects OSHA’s penalty calculation methodology: violations with high injury/death severity and a history of willful non-compliance generate penalties orders of magnitude larger than routine “Other” citations.
The construction sector faces disproportionate risk. Two of the top three standards (29 CFR 1926.0501 and 29 CFR 1926.0451) are construction-specific, and they account for $853 million in combined penalties. For construction employers, fall protection and scaffolding compliance should be the absolute top priority.
General industry has persistent “forgotten” hazards. Standards like power-transmission guarding (29 CFR 1910.0219) and abrasive wheel machinery (29 CFR 1910.0215) remain in the top 10 despite being well-understood for decades. These violations persist because guards are removed for convenience and never replaced — a cultural problem that requires management commitment to solve.
Lockout/tagout carries outsized consequences. While ranking 10th in citations, LOTO ranks 3rd in total penalties at $212 million. This standard is frequently the basis for Willful violation classifications after serious injury or death events, which carry penalties up to $161,323 per violation in 2024.
