What should be done if a hangfire is suspected after two attempts to fire?

When a hangfire is suspected after two attempts to fire, the appropriate course of action is to unload the canister and examine the primer. A hangfire occurs when there is a delay between the trigger pull and the firing of the round, which can pose significant safety risks. By unloading the canister, you reduce the potential hazards associated with a delayed ignition.

Examining the primer is crucial, as it can help identify whether there was a malfunction or defect that caused the hangfire. This examination allows the crew to assess the situation safely and determine the correct procedures for handling the misfire, preventing the risk of an unexpected discharge.

Immediate evacuation of the area is an important safety protocol, but the focus in this situation should be on confirming the condition of the equipment before taking further action. Attempting to fire again after two failed attempts is not advisable as it increases the risk of an uncontrolled detonation. Waiting indefinitely is also not practical; predefined protocols must be followed to ensure safety while addressing the situation. Therefore, examining the primer is the most logical and safety-oriented action to take in this scenario.
