What type of protective equipment is essential when handling hazardous materials?

When handling hazardous materials, the use of protective eyewear and gloves is essential to ensure safety. Protective eyewear safeguards against potential splashes, chemical exposure, or flying debris that could harm the eyes. Gloves provide a barrier between the skin and hazardous substances, reducing the risk of skin contact with harmful chemicals, biological agents, or other dangerous materials.

Using only a lab coat may not provide adequate protection, as it does not safeguard the eyes or hands, which are critical areas exposed to potential risks when working with hazardous materials. The option suggesting that no equipment is required neglects the importance of personal protective equipment (PPE) in maintaining a safe laboratory environment. While a mask can be vital for airborne chemicals, it does not offer protection for other exposure routes such as skin or eyes, making comprehensive protective gear, including eyewear and gloves, imperative in these situations.
