Which of the following is a vital step in maintaining a safe work environment?

Using personal protective equipment (PPE) is a vital step in maintaining a safe work environment because it provides a crucial layer of defense against various workplace hazards. PPE, which may include items such as helmets, gloves, goggles, and masks, is designed to protect workers from injuries or illnesses that could occur due to exposure to hazardous conditions or materials.

When employees wear the appropriate PPE, they significantly reduce their risk of accidents and injuries related to common workplace dangers such as falling objects, chemical exposure, or electrical hazards. The proper use of PPE is often mandated by regulations and industry safety standards, indicating its importance in promoting worker safety and health.

Other aspects listed, such as wearing inappropriate clothing, keeping tools scattered on the floor, or improperly storing hazardous materials, would not contribute to a safe work environment and could actually increase the risk of accidents or exposure to dangers.
