What is the purpose of PPE?

• A. A navigation tool
• B. A physical control that helps crews protect themselves from bodily harm
• C. A weather sensor
• D. A battery monitor

Answer: (B)

Personal protective equipment (PPE) is worn to shield you from hazards during UAS operations. It serves as a physical barrier that reduces the risk of injury to the body from impacts, debris, noise, chemicals, or other dangers you might encounter. Examples include eye protection, hearing protection, gloves, hard hats, and high-visibility clothing, selected based on the task and environment. This function is distinct from tools like navigation aids, weather sensors, or battery monitors, which perform their own sensing or measurement roles; PPE is specifically about protecting the person. Using PPE correctly is a key safety practice when working around rotors, power systems, and maintenance activities.
