Which term refers to controls that protect workers by modifying the workplace or equipment rather than by changing the hazard itself?

• A. Substitution
• B. PPE
• C. Administrative controls
• D. Engineering controls

Answer: (D)

Engineering controls focus on changing the work environment or the equipment itself to reduce exposure at the source. By adding guards, using ventilation or containment, or redesigning a process so the hazard is less likely to reach workers, these controls protect people even if they don’t act perfectly. That’s why they’re the best fit when the goal is to modify the workplace or equipment rather than the hazard itself. Substitution would mean replacing the hazardous material or process with something less dangerous, which directly changes the hazard rather than the environment. Administrative controls involve changing how people work—training, rules, or rotating tasks—without altering the physical setup. PPE provides a personal barrier between the worker and the hazard but doesn’t change the work environment or equipment.
