Which control method is least preferred for protecting workers from workplace hazards?

• A. Exposure and worker health monitoring
• B. Engineering controls
• C. Administrative controls
• D. Personal protective equipment

Answer: (D)

In protecting workers from hazards, the hierarchy of controls is the guiding concept. The most effective approach is to remove the hazard or separate people from it, followed by engineering controls that reduce exposure at the source, then administrative controls that change how work is done, and only after all of these is personal protective equipment used as a last line of defense. Personal protective equipment is the least preferred because it does not remove or reduce the hazard itself; it simply provides a barrier between the worker and the hazard. Its effectiveness depends on proper selection, correct fitting, training, and ongoing maintenance, and it can fail if equipment is worn out, improperly used, or damaged. PPE also relies on individual behavior and compliance, which can vary and may be less reliable in high-exposure or long-duration scenarios. It’s most appropriate to rely on PPE when hazards cannot be eliminated or adequately controlled by other measures, or to provide an additional layer of protection after higher-level controls have been put in place.
