Why are engineering controls preferred over personal protective equipment?

Engineering controls are preferred over personal protective equipment (PPE) primarily because they focus on eliminating hazards from the workplace rather than simply managing them. By redesigning processes, modifying equipment, or implementing barriers, engineering controls reduce or completely remove the risk associated with exposure to harmful substances like asbestos. This proactive approach significantly enhances worker safety by addressing the source of the hazard itself.

In contrast, personal protective equipment serves as a secondary line of defense, relying on individuals to consistently use it correctly and safely. While PPE is necessary in many situations, it does not eliminate the hazard; it simply reduces exposure once the hazard is present. Therefore, engineering controls are viewed as a more effective long-term solution for maintaining a safe work environment.

This emphasis on eliminating hazards underscores the importance of focusing on safe work practices that minimize risks at their source, ultimately leading to a healthier workplace for everyone involved.
