In 2023, private industry employers in the U.S. reported 2.6 million nonfatal workplace injuries and illnesses, still a significant burden despite an 8.4% drop from 2022, according to bls.gov. Globally, work-related fatalities reach nearly 3 million per year. Below are the 13 most frequent accident types—each with a clear focus statement, real-life case, supporting details, and preventive insight.
Common Types of Accidents in the Workplace
1. Overexertion and Repetitive Motion Injuries
Overexertion and repetitive strain from lifting or repetitive tasks rank among the most pervasive workplace injuries, causing strains, sprains, cumulative trauma disorders like tendonitis, and carpal tunnel syndrome.
Workers in manufacturing, transport, and healthcare report overexertion as the top injury, sprains and strains make up ~23% of all injuries in transportation/warehousing. A typical case involves a warehouse associate lifting 50 lbs boxes repeatedly, developing lower-back strain and sciatica that sidelines them for weeks. In healthcare roles, repetitive tasks like patient transfers often lead to musculoskeletal damage from improper body mechanics.
Real-world example: A nurse making frequent bed adjustments without mechanical lifts winds up with a herniated disc, common in health/social services, where incidence rates reach 3.6 cases per 100 full-time equivalent workers.
Encourage micro-breaks, stretch routines, ergonomic education, and mechanical aids. Investing in powered lifters and rotating task responsibilities is cost-effective—fewer days off, more productivity.
2. Slips, Trips & Falls
Falls—either on the same level or from heights—are consistently among the top causes of workplace injury and death, triggered by wet floors, obstacles, poor lighting, and lack of fall protection.
Slips, trips, and falls cause over one-third of nonfatal occupational injuries and 20% of workplace deaths. Same-level falls (no height) often stem from cluttered aisles or wet floors—think food service or warehouse spills. Falls from heights, especially in construction and roofing, are the fourth leading cause of workplace death, with 680 fatal elevation falls in the U.S. in 2022.
Case study: A technician slips on a recently mopped factory floor and suffers a wrist fracture; a construction worker, unanchored on scaffolding, falls and sustains T‑spine injuries—all ultimately preventable.
Implement clear signage, stable housekeeping, and lighting. Utilize guard rails, safety nets, and harness systems. Training must cover both technique and hazard awareness.
3. Struck‑by or Struck‑against Objects
Getting struck by moving or falling objects—tools, machinery, vehicles—is a frequent and severe cause of workplace harm, leading to bruises, fractures, concussions, or amputations.
OSHA cites “struck-by” incidents among the top injury causes. Amazon UK reported 119 serious injuries—fractures, amputations—from struck-by events between 2019–2024. In construction, dropped tools and swinging materials lead to this dangerous category.
Real-world scenario: A forklift operator negligently backs into a pedestrian, causing leg fractures and hospitalization.
Enforce clear “no-go” zones, visual and audible forklift warnings, secure tool lanyards, and head protection. Ongoing safety audits catch violations early.
4. Caught‑in or Compressed By Objects/Equipment
Accidents where workers are caught, crushed, or pinched by moving machinery, vehicles, or collapsing structures are serious and often life-altering.
These incidents account for 3.4% of all work injuries, with damage often catastrophic. From conveyor belt entrapment in warehouses to scaffolding collapse, risks are omnipresent.
Real incident: A worker’s arm is drawn into an improperly guarded packaging machine, resulting in a traumatic amputation.
Mandatory lock‑out/tag‑out during maintenance, guarding on all pinch points, emergency stop systems, and regular machinery inspections greatly reduce the occurrence.
5. Falls from Heights
Falls from elevation are among the deadliest incidents, especially in sectors like construction, roofing, and maintenance, and most occur when fall protection is missing or misused.
Elevational falls accounted for 13% of U.S. occupational fatalities in 2022, around 680 deaths. In the EU, construction accounts for 22.9% of fatal workplace accidents.
Example: A roofer neglects to attach a harness before stepping onto a sloped roof and falls, resulting in spinal injury.
Employers must enforce the fall protection hierarchy: eliminate hazards where possible, implement prevention (rails, nets), provide arrest systems, and administer fall-hazard training.
6. Electrical Injuries and Electrocution
Contact with live electrical circuits or equipment causes burns, shocks, cardiac arrest, and death—an ever-present threat when working near electrocution hazards.
Example: A Sydney electrician dies after touching a live wire in the roof space. Globally, electrocution ranks high among fatal workplace injuries.
Always de‑energize circuits before work, voltage test, use insulated tools and gloves, and wear arc-rated PPE. Permit-to-work systems reduce risk.
7. Burns & Thermal Injuries
Burns from fires, hot surfaces, steam, chemicals, or electricity are common, leading to painful and costly injuries, and in serious cases, disfigurement or death.
Burns are one of the top five injury types after overexertion, falls, and transportation incidents.
Scenario: A restaurant worker suffers deep second-degree burns after hot oil splashes out of a fryer during rush hour.
Install shields, enforce PPE like heat-resistant gloves and aprons, train employees for proper handling, and maintain emergency wash stations.
8. Chemical Exposure and Poisoning
Unplanned contact with toxic substances—via skin, inhalation, or ingestion—can cause acute burns, respiratory illness, neurological harm, or chronic disease.
Overexposure to chemicals or substances appears across multiple industrial sectors. Smaller on‑site spills may be overlooked, yet still pose severe risks.
Example: A lab technician inhales acidic fumes from a broken reagent bottle and develops pulmonary irritation.
Rely on Safety Data Sheets, proper labeling, containment, ventilation, respirators, and regular training on spill response and personal hygiene.
9. Ergonomics‑Related (Musculoskeletal) Injuries
Poor workplace ergonomics—awkward posture, repetitive motions, high force—leads to chronic musculoskeletal disorders like back pain, shoulder strain, and tendinitis.
Back injuries in U.S. construction run 50% higher than average. Globally, MSK injuries are among the most reported nonfatal injuries.
Case: A warehouse associate formulates rotator cuff issues after consistently reaching overhead for inventory without support.
Implement ergonomic assessments, adjustable workstations, tool redesign (e.g., extension handles for drills), powered assistance, regular breaks, and posture awareness programs.
10. Machine‑Related Incidents
Operating machinery without proper guarding, maintenance, or training can result in amputations, fractures, crushing injuries, or fatalities.
A machine missing safety interlocks might suddenly power up during cleanup, accidentally severing fingers. OSHA reports high fatality numbers near unguarded moving parts.
Routine guard inspections, interlock function tests, safe maintenance procedures, lock‑out/tag‑out protocols, and operator training are essential.
11. Vehicle and Transportation Incidents
Collisions involving forklifts, trucks, and company vehicles are among the leading causes of workplace fatal incidents, especially in logistics and field work.
U.S. transportation accidents account for up to 40% of work-related deaths. Delivery and transport workers are especially vulnerable.
Scenario: A delivery driver, fatigued from schedule pressure, runs a red light and causes a fatal crash.
Enforce driver training, vehicle inspection, fatigue policies, route planning, and telematics for safe driving reinforcement.
12. Workplace Violence and Homicide
Intentional acts of violence—including assaults, robberies, and active shooter events—are increasingly recognized and deadly in certain workplace environments.
Violence is the second most common workplace fatality cause after transportation in the U.S., roughly 500 occupational homicides per year.
Example: A cashier is fatally shot during a late-night robbery, highlighting vulnerabilities in retail.
Implement security cameras, panic buttons, secure entrances, lighting, de-escalation training, and safety protocols for high-risk roles.
13. Heat‑Related Illness
Working in extreme heat without proper mitigation leads to heat exhaustion, heat stroke, reduced mental performance, and rising accident rates.
Climate-induced heat stress claims are climbing, especially in outdoor and semi-outdoor industries.
Incident: A construction worker collapses on a roof in 40 °C heat, requiring hospitalization.
Provide hydration, shaded/rest breaks, adjusted schedules, acclimatization training, heat monitors, and buddy systems during heat waves.
