When a fire area is protected by a water mist system, hazards include which of the following?

• A. Eye hazards
• B. Hearing hazards
• C. Reduced visibility
• D. Eye hazards, hearing hazards, and reduced visibility

Answer: (D)

When a fire area is protected by a water mist system, the fine spray created can bring together three common hazards. The tiny droplets can irritate or injure eyes if they come into contact with them, especially in a smoky or contaminated environment. The system’s pumps, valves, and alarms also generate noticeable noise, creating a potential hearing hazard for occupants and responders. Additionally, the visible mist and added moisture reduce visibility, making navigation and escape more difficult. Because all of these conditions can occur together in a space with water mist, all three hazards are present.
