What type of personal protective equipment protects operators from inhaling fumes, gases, and other airborne hazards?

The correct choice is the respirator, as it is specifically designed to protect the respiratory system from inhaling harmful substances such as fumes, gases, and other airborne hazards. Respirators come in various types, including particulate respirators and gas masks, each tailored to filter out specific contaminants and provide a barrier against inhaling dangerous substances in the workplace.

While face shields, hard hats, and safety goggles serve important safety purposes, they do not provide protection against inhalation of airborne materials. A face shield primarily protects the face from impact and splashes, a hard hat is used to protect the head from falling objects and impacts, and safety goggles are designed to protect the eyes from flying debris or chemical splashes. Therefore, for airborne hazards specifically, respirators are essential personal protective equipment to ensure the health and safety of operators.
