What is the requirement for wood used in the plant?

• A. It must be painted.
• B. It must be fire retardant unless written permission is obtained.
• C. It can be untreated with no permission needed.
• D. It must be replaced annually.

Answer: (B)

The key idea is fire safety: in a plant, wood should be fire retardant to slow ignition and limit flame spread, buying time to detect and control a fire and protecting people and equipment. The rule allows an exception only if written permission is obtained, meaning untreated wood can be used only with formal authorization. Painting wood does not guarantee fire resistance, and using untreated wood without permission is unsafe and not the standard practice. Replacing wood annually isn’t a typical requirement and doesn’t address fire behavior.
