Final answer:
Firefighters are trained in hostile fire indicators, which are crucial for assessing dangerous fire events and ensuring the safety of both the victims and the firefighters.
Step-by-step explanation:
Firefighters are typically trained in hostile fire indicators to recognize warning signs for hostile fire events. These indicators help firefighters assess fires and situations effectively. When firefighters search burning buildings, they employ these indicators to locate fire victims safely while dressed in fire-resistant clothing and using breathing apparatus for protection against smoke and toxic gases. Additionally, firefighters are equipped to rescue victims from burning buildings, accident sites, and water hazards, and provide life-saving measures such as first aid and cardiopulmonary resuscitation (CPR). Communicating the conditions and receiving instructions through two-way radios is a critical part of a firefighter's job when assessing and responding to fire scenes.
