The safety benefits of a well-run preventative maintenance program
When most people think of preventive maintenance (PM), they see it as a way to avoid costly breakdowns and keep production running. While that is true, it’s only part of the story. A well-run PM program is one of the most effective and underrated safety tools an employer can have. From preventing equipment-related injuries to avoiding hazardous leaks or fires, PM isn’t just about operating efficiently. It’s about keeping employees, the environment, and the bottom line safe.
How equipment failure turns into a hazard:
Neglected maintenance can create serious risks, including:
- Mechanical failures – unmaintained machinery can suddenly seize, break apart, or eject parts.
- Electrical hazards – frayed cords, worn insulation, or faulty breakers can cause shocks or fires.
- Chemical releases – worn seals, cracked tanks, or failed valves can ultimately lead to hazardous spills.
- Ergonomic strain – poorly calibrated or damaged equipment can force employees into awkward or unsafe positions.
These risks aren’t just hypothetical; OSHA frequently cites employers after incidents where the root cause was poor or non-existent preventative maintenance.
Key elements of a safety driven PM program:
- Risk based scheduling – prioritize maintenance on equipment with the greatest safety risks (ex. forklifts, overhead cranes, pressure vessels, and electrical systems). Maintain a critical equipment registry that highlights assets where failure could lead to injury or regulatory violations.
- Standardized procedures – document step-by-step PM tasks with a strong emphasis on safety. For example, include lockout/tagout steps, PPE requirements, and confined space entry procedures. Train employees to follow SOPs consistently to reduce human error.
- Qualified personnel – preventative maintenance is only as good as the people performing it. Ensure technicians are trained not only on the task, but on the safety hazards of the equipment.
- Integrated safety checks – incorporate safety specific items in PM inspections such as checking emergency stops, guarding, grounding, or ventilation performance.
- Document everything – use digital tracking to log inspections, repairs, and part replacement. This protects employers during audits and helps spot recurring issues.
- Operator involvement and pre-use checks – empower front-line employees to perform daily pre-use inspections such as forklift inspections and machine guarding verification. Create simple reporting tools to flag issues before they escalate.
- Corrective action and follow-up – establish a system for tracking identified hazards until resolution through work orders or corrective action logs. Communicate completion of corrective actions to affected employees.
A well-run preventative maintenance program is, at its heart, a safety program. While cost savings and productivity gains are valuable, the greatest benefit is protecting workers from harm’s way. By preventing equipment failures, ensuring safety systems function correctly, and reinforcing a culture of care, PM programs create a safer workplace where employees can perform their jobs with confidence. Simply put, machines can be replaced – people cannot. That’s why preventative maintenance isn’t just smart business, it’s a commitment to worker safety.
Keys to remember: A safety driven PM program isn’t just about keeping machines running. It’s about making sure every inspection, service, and repair is performed with worker safety in mind.
