What must technicians wear as a mandatory safety procedure when they risk exposure to biohazards?

Technicians must wear personal protective equipment (PPE) when there is a risk of exposure to biohazards. PPE is designed to protect individuals from various hazards, including biological agents that could pose health risks. It encompasses a range of protective gear, including gloves, gowns, masks, eyewear, and face shields, ensuring comprehensive protection against contamination.

Using PPE is critical when handling biohazardous materials, as it not only safeguards the technician's health but also minimizes the potential spread of harmful pathogens. Each piece of equipment plays a specific role in creating a barrier against exposure, which is essential when working in environments where biohazards are present.

While other options like safety glasses, gloves, and respirator masks are indeed important components of PPE, they do not represent the complete protective strategy needed for comprehensive biohazard situations. PPE signifies a holistic approach to safety, integrating multiple layers of protection suited for the specific risks technicians may encounter.
