Final answer:
Wait a minimum of 30 minutes in the event of a potential cook-off before taking further action to ensure safety.
Step-by-step explanation:
In the context of firearms and ammunition safety, a cook-off is an event where a round of ammunition discharges due to excessive heat in the chamber of a firearm, not due to a deliberate firing action. If one encounters a situation where a round cannot be extracted and there is a risk of cook-off, the general guideline is to wait a minimum of 30 minutes before taking any further action. This waiting period is a critical safety measure to ensure that any potential cook-off has ample time to occur without endangering anyone nearby.
