Which of the following is not a type of PPE?

Personal Protective Equipment (PPE) is designed to protect workers from hazards that can cause injury or illness in the workplace. Common types of PPE include items such as respirators, safety shoes, and face shields, all of which serve specific safety functions.

Respirators are designed to protect the wearer from inhaling harmful dust, fumes, vapors, or gases. Safety shoes provide protection for the feet from heavy objects, sharp items, and slippery surfaces. Face shields protect the face from impacts, splashes, and other hazardous materials.

Ergonomic chairs, however, are primarily designed to enhance comfort and promote good posture while sitting, especially during tasks that involve prolonged sitting, such as office work. While they contribute to the overall health and comfort of workers, ergonomic chairs do not provide protection from physical hazards, which is the defining characteristic of PPE. Therefore, this option is correctly identified as not being a type of PPE.
