Fire warden

Firefighting is the act of attempting to prevent the spread of and extinguish significant unwanted fires in buildings, vehicles, woodlands, etc. A firefighter suppresses fires and performs rescues to protect lives, property and the environment. Firefighters may provide other services to their communities.

Firefighters typically undergo a high degree of technical training. This involves both general firefighting techniques and developing specialist expertise in particular fire operations, such as aircraft firefighting and wildland firefighting In the U.S. the national level of certifications are called Firefighter I/II.

One of the major hazards associated with firefighting operations is the toxic environment created by combustible materials. The four major risks are smoke, oxygen deficiency, elevated temperatures, and poisonous atmospheres. Additional hazards include falls and structural collapse that can exacerbate the problems entailed in a toxic environment. To combat some of these risks, firefighters carry self-contained breathing equipment.

The first step in a firefighting operation is reconnaissance to search for the origin of the fire and to identify the specific risks.

Fires can be extinguished by water, fuel or oxidant removal, or chemical flame inhibition.

The earliest known firefighters were in the city of Rome. In 60 A.D., emperor Nero established a Corps of Vigils (Vigiles) to protect Rome after a disastrous fire. It consisted of 7,000 people equipped with buckets and axes, and they fought fires and served as police.

In the 4th century B.C., an Alexandrian Greek named Ctesibius made a double force pump called a siphona. As water rose in the chamber, it compressed the air inside, which forced the water to eject in a steady stream through a pipe and nozzle.

In the 16th century, syringes were also used as firefighting tools, the larger ones being mounted on wheels. Another traditional method that survived was the bucket brigade, involving two lines of people formed between the water source and the fire. Typically, men in one of the lines would pass along the full buckets of water toward the fire while in the other line women and children would pass back the empty buckets to be refilled.
