Should personal protective equipment (PPE) be considered before implementing engineering or work practice controls?

Personal protective equipment (PPE) serves as a crucial last line of defense against workplace hazards, particularly in confined spaces. The rationale behind prioritizing engineering or work practice controls before considering PPE lies in the hierarchy of controls, a widely accepted safety framework. This hierarchy advocates for the elimination or minimization of hazards through preferred methods such as engineering controls—like ventilation systems or barriers—and administrative controls, which alter work practices to improve safety.

When effective engineering or work practice controls are employed, they reduce the inherent risks associated with confined spaces, often rendering the need for PPE unnecessary or less critical. Thus, implementing PPE without first exploring and applying these other control measures may lead to a false sense of security. The focus should be on minimizing hazards at the source rather than relying solely on protective gear, which may not always provide complete protection.

While PPE is essential and cannot be overlooked, particularly for residual risks, it should not be the first consideration before evaluating and utilizing more effective controls. This approach not only enhances safety but also ensures compliance with OSHA regulations and promotes a proactive culture of safety in the workplace.
