What materials are typically considered hazardous during a fire incident?

Batteries, chemicals, flammable liquids, and pressurized containers are classified as hazardous materials during a fire incident due to the potential risks they pose. These materials can ignite easily, contribute to the intensity of the fire, and may produce toxic fumes when burned. For example, flammable liquids can spread fire quickly, while pressurized containers can explode or rupture under heat, further endangering firefighting efforts and the safety of individuals nearby.

Understanding the dangers associated with these specific materials is critical for appropriate emergency response and safety measures. It enables firefighters and safety personnel to take the necessary precautions and develop effective strategies to manage a fire incident involving such hazardous substances.
