Final answer:
The ISO should consider thermal energy when assessing hazardous energy related to weather extremes and their effects on incidents and responders.
Step-by-step explanation:
The Incident Safety Officer (ISO) should consider thermal energy as a form of hazardous energy and weigh the effects of weather extremes with the behavior of the incident and of the incident responders. Thermal energy is related to the motion of atoms and molecules; the faster they move, the higher the thermal energy. In the context of weather-related incidents, extreme temperatures can impact not only the behavior of an incident but also the safety and performance of responders. Furthermore, considering the effects of solar radiation, which is an example of radiant energy, can also be critical when assessing incident safety. It is important to note that solar events can impact space weather, potentially disrupting various aspects of our civilization that depend on technology.
