On a water spray system where caps and plugs are required, how shall they be secured?

• A. Be in place and free to operate as intended
• B. Secured in place by any means
• C. Secured with tape
• D. A thin bead of adhesive

Answer: (A)

Caps and plugs on a water spray system must stay in place and remain free to operate as intended. They serve to close openings while allowing easy removal for testing and maintenance, so they should be installed so they can be removed or opened without tools beyond what is specified and without being impeded by permanent sealing methods. Securing them by tape, adhesive, or “any means” can hinder removal, leave residues, or degrade the closure’s effectiveness, which is why those methods aren’t acceptable. The goal is closures that stay put yet do not compromise accessibility or operability during inspections and service.
