Fire safety requires understanding the elements of fire - fuel, oxygen, and heat. Fires can start from accidents, electrical issues, appliances, and unattended flames. Different types of fires involve solids, gases, electricity, or metals. When a fire occurs, remain calm and have an escape plan. To prevent fires, install alarms and avoid overloading outlets or leaving cooking unattended. If a fire does start, act quickly to put it out safely or evacuate to call for help.
