Wearing Personal Protective Equipment (PPE) is essential when handling hazardous materials in the lab because it significantly reduces the risk of exposure to harmful substances. PPE serves as a barrier between the individual and the hazardous materials, helping to protect against spills, splashes, and other potential accidents that could result in injury or illness. This equipment typically includes items such as lab coats, gloves, safety goggles, and face shields, all specifically designed to safeguard different parts of the body from exposure to chemicals, biological agents, or physical hazards.

While comfortable shoes and loose clothing can enhance comfort and mobility, they do not provide the necessary protection against hazardous materials. Jewelry, although it may serve identification or aesthetic purposes, can pose a safety risk in a lab environment by accidental entanglement or contamination. Thus, the only appropriate and vital choice for ensuring safety when dealing with hazardous materials is the use of PPE.
