Workplace injuries cost employers more than $1 billion per week in direct workers’ compensation costs, according to Liberty Mutual’s 2025 Workplace Safety Index. Most of these injuries are preventable. The most effective prevention starts not with safety gear or training, but with removing hazards before workers ever encounter them.
The Hierarchy of Controls
OSHA ranks workplace safety measures from most to least effective in five tiers. Understanding this ranking helps you invest time and money where it matters most.
Elimination is the most effective approach: remove the hazard entirely. If a task requires workers to climb to a dangerous height, redesign the process so the work happens at ground level. Substitution is the next best option, meaning you swap a hazardous material or process for a less dangerous one, like replacing a toxic solvent with a water-based cleaner.
Engineering controls physically separate workers from hazards. Machine guards, ventilation systems, and noise barriers all fall into this category. These don’t rely on anyone remembering to follow a rule. Administrative controls change how work gets done through procedures, signage, job rotation, and training. They’re less reliable because they depend on human behavior. Personal protective equipment (PPE), the familiar hard hats, gloves, and safety glasses, sits at the bottom. It’s the last line of defense, not the first.
Too many workplaces skip straight to handing out PPE. That approach treats the symptom instead of the cause. A well-designed prevention program works down the hierarchy, starting with elimination and only reaching for PPE when higher-level controls aren’t feasible.
Where Injuries Happen Most
OSHA’s top 10 most frequently cited violations for 2024 reveal where companies consistently fall short. Fall protection topped the list for yet another year, followed by hazard communication failures, ladder safety violations, and respiratory protection issues. Rounding out the list: lockout/tagout violations (failing to shut down equipment during maintenance), forklift safety, fall protection training gaps, scaffolding problems, eye and face protection, and machine guarding.
This list is a practical blueprint. If your workplace involves heights, powered equipment, chemicals, or heavy machinery, those are the areas most likely to cause injuries and the ones regulators will scrutinize first. Addressing these specific categories eliminates a disproportionate share of your risk.
Ergonomics and Repetitive Strain
Musculoskeletal disorders from repetitive motion, awkward postures, and sustained positions account for a huge portion of workplace injuries, and they develop gradually enough that people often ignore early warning signs. For office workers, proper workstation setup makes a real difference: the top of your monitor should sit at or just below eye level, your elbows should stay close to your body and supported, and your lower back needs firm support from your chair.
For jobs that involve lifting, the National Institute for Occupational Safety and Health developed a lifting equation that calculates the maximum safe weight based on several factors: how far the object sits from your body, how high off the floor you’re gripping it, how far you need to move it vertically, whether you’re twisting during the lift, how often you repeat it, and how good your grip is. Every one of those factors reduces the safe weight limit. A box you can safely lift once from waist height directly in front of you becomes dangerous when you’re reaching across a table, twisting, and repeating the motion every few minutes for hours.
The practical takeaway: store heavy items between knee and shoulder height, keep loads close to the body, avoid twisting while carrying weight, and use mechanical aids like carts, dollies, or lift-assist devices whenever possible.
Preventing Slips, Trips, and Falls
Falls remain the single most cited safety violation in the country for good reason. Prevention covers two fronts: keeping people from falling off elevated surfaces and keeping them from falling on level ground.
For elevated work, guardrails are engineering controls that don’t depend on worker behavior. Safety nets and personal fall arrest systems add backup layers. For ground-level slips and trips, flooring material matters more than most people realize. NIOSH recommends flooring with a static coefficient of friction above 0.5 in high-risk areas, a number that increases with slip-resistant footwear and clean, dry surfaces. Proper lighting throughout all indoor and outdoor areas reduces shadows and glare so workers can actually see surface irregularities and obstacles. Something as simple as replacing burnt-out bulbs promptly prevents trips that seem random but are entirely predictable.
Housekeeping is the cheapest and most underused fall prevention tool. Cords routed across walkways, spills left for the next person, boxes stacked in aisles: these create hazards that no amount of training can fully compensate for.
Managing Fatigue and Shift Length
Fatigue is one of the most dangerous and least visible risk factors in any workplace. Research published in the Industrial Psychiatry Journal found that the risk of fatigue-related incidents increases exponentially once shifts reach 12 hours, and that early-start shifts compound the problem. An estimated 20 to 30 percent of road accidents involve driver fatigue, along with 5 to 15 percent of fatal road accidents.
The fix involves scheduling discipline. Avoid overtime on 12-hour shifts, provide at least 24 hours of rest between shifts, and build break periods into the workday. Even a short nap of 30 minutes or less measurably improves alertness and performance immediately upon waking. If your workplace culture treats breaks as laziness, that culture is producing injuries.
Why Near-Miss Reporting Matters
For every injury that gets reported, research estimates there are 10 to 100 near-miss incidents associated with it. Those near misses are free warnings. Studies have found that workplaces with active near-miss reporting programs experience fewer high-severity incidents over time, because each report reveals a hazard before it causes real harm.
The challenge is getting people to actually report. Workers skip near-miss reports when they fear blame, when the reporting process is cumbersome, or when they see no evidence that previous reports led to any change. An effective system makes reporting easy (a simple form or app), responds visibly to reports (even if the response is explaining why no action was needed), and treats reports as valuable data rather than complaints. Near misses are a leading indicator. Injury counts are a lagging one. By the time you’re counting injuries, you’ve already missed the window to prevent them.
Training That Actually Sticks
Not all safety training is equally effective. Research in the American Journal of Public Health found that low-engagement training methods, think lectures and videos, lost roughly 50 percent of their effectiveness within weeks to a year after the initial session. Moderately engaging training (discussions, demonstrations) retained knowledge much better, losing only about 15 percent over four weeks. Highly engaging training that involved hands-on practice maintained its full effect over the same period.
This means a yearly PowerPoint presentation is close to worthless as a standalone strategy. Training works best when it’s hands-on, repeated at reasonable intervals, and directly relevant to the hazards workers face in their specific roles. Short, focused refreshers beat long, infrequent sessions.
PPE: Your Employer’s Responsibility
If your job requires personal protective equipment, your employer is legally required to pay for it. OSHA’s rule on this is clear: employers must assess workplace hazards, identify appropriate PPE, provide it at no cost, train workers on its use, and replace worn or damaged equipment. Employers cannot require workers to supply their own PPE. If a worker chooses to use personal equipment, the employer still has to verify it provides adequate protection.
There are a few exceptions. Employers don’t have to pay for non-specialty steel-toe boots or prescription safety glasses if workers are allowed to wear them off-site. Ordinary weather gear like winter coats and sunscreen, everyday clothing, and food-service items like hairnets also fall outside the requirement. Notably, OSHA excludes lifting belts from required PPE because evidence for their protective value is inconclusive.
PPE only works when it fits properly, is worn consistently, and is maintained. A hard hat with a cracked shell or safety glasses that fog up and get removed defeat the purpose entirely. Regular inspection and replacement are part of the legal requirement, not optional extras.
