What transmitter power limitations must be observed by an amateur radio operator in distress?

During a genuine distress situation where life or property is in immediate danger, all normal regulatory limitations on transmitter power are lifted. The absolute priority is to ensure the distress signal is heard by anyone capable of providing assistance. While amateurs normally must adhere to strict power limits based on their license qualifications (such as 1000 watts DC input or specific PEP limits), a distress scenario creates an overriding exception. An operator may use whatever power level their equipment is capable of producing to establish critical emergency contact.
