Step-by-step explanation:
The main objectives of first aid include saving lives, preventing further injuries, and promoting recovery. In the context of emergency situations such as fire rescues and accidents, first aid objectives extend to swiftly and safely evacuating individuals from imminent danger, such as searching and rescuing victims from burning buildings and accident sites. Once the individuals are safe, administering first aid and cardiopulmonary resuscitation (CPR) becomes crucial to treat injuries and stabilize patients before emergency services arrive or before they can be moved to a hospital for further treatment. An emphasis is also placed on the use of appropriate safety equipment and techniques to prevent injury, such as wearing fire-resistant clothing and breathing apparatuses. The practices of warming up, cooling down, and stretching are highlighted for injury prevention during physical activities.
