What type of protective equipment is essential when working with hazardous substances?

When working with hazardous substances, Personal Protective Equipment (PPE) is essential because it encompasses a range of protective gear designed to safeguard workers from various risks associated with exposure to those substances. PPE can include gloves, masks, respirators, safety goggles, face shields, and protective clothing, depending on the specific hazards present.

The use of PPE is critical in maintaining safety by reducing the likelihood of injury or health issues caused by chemical exposure, splashes, inhalation of toxic vapors, or other hazards. This comprehensive approach ensures that workers have multiple layers of protection tailored to the type of work being performed, thus enhancing overall safety in hazardous environments.

The other options may provide some level of protection but do not fully encapsulate the broad spectrum of equipment necessary for ensuring safety when dealing with hazardous substances.
