Workplace safety is a critical concern for employers and employees alike. Across industries—from construction and manufacturing to healthcare and office environments—hazards can lead to injuries, illnesses, lost productivity, and costly regulatory penalties. The Occupational Safety and Health Administration (OSHA) was established to reduce these risks by setting and enforcing standards and by providing training that helps organizations create safer work environments.

OSHA trainings play a vital role in identifying workplace hazards, teaching employees how to avoid them, and ensuring compliance with safety regulations. Below are 11 of the most common workplace hazards and how OSHA training helps mitigate each one.

1. Slips, Trips, and Falls

According to Keevee, slips, trips, and falls account for a whopping 25% of workplace injuries, making them one of the most prevalent and preventable types of accidents. Wet floors, uneven surfaces, loose cables, poor lighting, and cluttered walkways can all contribute to dangerous conditions. These incidents can result in anything from minor bruises to serious fractures or head injuries.

OSHA trainings emphasize hazard recognition and prevention strategies, such as proper housekeeping, use of non-slip mats, installation of guardrails, and immediate cleanup of spills. Employees are trained to report hazards promptly and to wear appropriate footwear. OSHA’s Walking-Working Surfaces standards provide clear guidance that helps employers reduce fall-related incidents.

2. Hazardous Chemical Exposure

Many workplaces use chemicals that can be harmful if inhaled, ingested, or absorbed through the skin. Improper handling, storage, or disposal of these substances can lead to burns, respiratory issues, poisoning, or long-term health conditions.

OSHA’s Hazard Communication (HazCom) training teaches employees how to read Safety Data Sheets (SDS), understand labeling requirements, and use proper personal protective equipment (PPE). Workers learn safe handling procedures and emergency response steps, significantly reducing the risk of chemical-related injuries and illnesses.

3. Electrical Hazards

Electrical hazards include exposed wiring, overloaded circuits, damaged equipment, and improper grounding. These hazards can cause electric shocks, burns, fires, or even fatalities if not properly managed.

OSHA training focused on electrical safety provides information on lockout/tagout procedures, the safe use of electrical equipment, and how to recognize common warning signs of electrical danger. Employees are trained to de-energize equipment before maintenance and to maintain safe distances from live electrical parts, helping prevent serious accidents.

4. Ergonomic Hazards

Ergonomic hazards occur when workstations, tools, or tasks are not designed to fit the worker. Repetitive motions, awkward postures, heavy lifting, and prolonged sitting can lead to musculoskeletal disorders such as carpal tunnel syndrome, back injuries, and neck strain.

Quality OSHA trainings address ergonomic principles by teaching employees proper lifting techniques, workstation setup, and task rotation. Workers learn how to adjust chairs, desks, and monitors, and how to recognize early signs of strain. These proactive measures help reduce long-term injuries and improve overall comfort and productivity.

5. Falling Objects

In warehouses, construction sites, and industrial facilities, falling objects pose a significant risk. Tools, materials, or equipment dropped from heights can cause severe injuries to workers below.

OSHA trainings emphasize the use of hard hats, proper stacking and storage practices, and the use of toe boards, nets, and barricades. Employees are trained to secure tools when working at heights and to maintain clear communication on job sites, minimizing the risk of struck-by incidents.

6. Machine and Equipment Hazards

Unguarded or improperly maintained machinery can cause cuts, amputations, crush injuries, and fatalities. Moving parts, sharp edges, and pinch points are especially dangerous when safety protocols are ignored.

OSHA’s machine guarding and equipment safety training teaches employees how to operate machinery safely, recognize hazardous components, and follow proper maintenance procedures. Lockout/tagout training ensures that machines are fully shut down during servicing, protecting workers from unexpected startups.

7. Fire and Explosion Hazards

Fire hazards can arise from flammable materials, faulty electrical systems, improper storage of combustibles, or lack of fire prevention measures. Explosions may occur in environments with combustible dust, gases, or vapors.

OSHA trainings on fire safety cover fire prevention plans, proper storage of flammable substances, and correct use of fire extinguishers. Employees learn evacuation procedures, alarm systems, and emergency response actions, which can save lives and limit property damage during an incident.

8. Confined Space Hazards

Confined spaces such as tanks, silos, tunnels, and pits can present serious risks due to limited ventilation, toxic atmospheres, or restricted entry and exit points. Without proper precautions, workers may face suffocation, poisoning, or entrapment.

OSHA confined space training teaches workers how to identify permit-required confined spaces, test air quality, use ventilation equipment, and follow entry and rescue procedures. This specialized training ensures that only qualified personnel enter these spaces under controlled conditions.

9. Noise Exposure

Excessive workplace noise from machinery, tools, or industrial processes can lead to hearing loss and increased stress levels. Noise-induced hearing damage often occurs gradually, making it an overlooked hazard.

OSHA trainings on occupational noise exposure educate employees about permissible exposure limits and the importance of hearing protection. Workers learn how to use earplugs or earmuffs correctly and how to recognize signs of hearing damage, helping prevent long-term auditory issues.

10. Workplace Violence and Stress

Workplace hazards are not always physical. Violence, harassment, and chronic stress can negatively impact employee mental health and safety. These issues can lead to decreased morale, higher turnover, and increased risk of accidents.

OSHA training programs increasingly address workplace violence prevention and stress management. Employees are trained to recognize warning signs, de-escalate conflicts, and report concerns safely. Creating awareness and clear policies helps foster a safer, more supportive work environment.

The Role of OSHA Trainings in Building a Safety Culture

Beyond addressing individual hazards, OSHA training helps organizations build a strong safety culture. When employees understand the risks associated with their jobs and know how to protect themselves, safety becomes a shared responsibility rather than an afterthought.

Regular training sessions, refreshers, and updates ensure that safety knowledge remains current and relevant. Employers who invest in OSHA-compliant training often see reduced injury rates, lower workers’ compensation costs, and improved employee confidence.

11. Inadequate Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) is often the last line of defense against workplace hazards, yet injuries frequently occur when PPE is unavailable, improperly selected, or incorrectly used. Common issues include workers not wearing required gear, using damaged equipment, or lacking training on how PPE should fit and function.

OSHA trainings place strong emphasis on proper PPE selection, use, and maintenance. Employees are taught which types of PPE are required for specific tasks—such as gloves, eye protection, respirators, or fall protection harnesses—and how to inspect them for defects before use. Training also reinforces when PPE must be worn and how to store and replace it correctly. By ensuring workers understand the purpose and proper use of PPE, OSHA training significantly reduces the likelihood of preventable injuries.

Workplace hazards exist in every industry, but they don't have to result in injuries or fatalities. By identifying common risks and implementing effective OSHA trainings, employers can significantly reduce accidents and create safer working conditions.
