What is the recommended practice when testing watertight fittings to ensure safety?

• A. Slowly loosen dogs, door handle
• B. Turn valve fully
• C. Force open doors
• D. Remove gaskets

Answer: (A)

When testing watertight fittings, introduce pressure in a controlled, gradual way so you can observe the seal without shocks or sudden breaches. Slowly loosen the latching devices (dogs) and the door handle. This lets you check for leaks as the seal seats, reduces the risk of damage to gaskets or components, and keeps personnel safe by avoiding sudden movement or pressure.

Turning the valve fully can cause a rapid change in pressure and potentially force water through the seal; forcing doors can cause physical injury or structural damage; removing gaskets defeats the purpose of the test and guarantees leaks.
