Which of the following is a primary goal of PPE?

The primary goal of personal protective equipment (PPE) is to protect workers from hazards that may cause injury or illness in the workplace. PPE serves as a critical line of defense against various physical, chemical, biological, and mechanical hazards present in construction and other industrial environments. By providing necessary protection, PPE helps to minimize the risk of accidents, injuries, and long-term health effects associated with exposure to harmful conditions.

In contrast, the other options focus on aspects that are not central to the function of PPE. Reducing workplace aesthetics, enhancing machinery performance, and complying with aesthetic regulations do not contribute to the core purpose of PPE, which is centered solely around the safety and protection of employees engaged in potentially hazardous tasks.
