While the main part of a firefighter's job is to fight fires, there is much more that they are responsible for doing. The aforementioned tasks are only a few of what most firefighters will need to do.

Like most things, when air is heated to an appropriate amount, it will expand. Molecules will also move faster, and hot air will often float upward. That is essentially how hot air balloons are able to fly.

An incident commander is one of the most important people on the fire company when it arrives at a scene. They develop objectives, are responsible for everyone else and manage all operations.

Smoke is made up of carbon dioxide, carbon monoxide and particulate matter. Of course, smoke can also contain a wide range of different chemicals depending on what is burning.

The average rate for an adult heartbeat is between 60 and 100 beats per minute. This will vary depending on a number of things, but anything between that range is normal. Some extreme athletes, however, might see theirs drop a bit lower.

Unfortunately, if your brain cells do not have access to oxygen, you don't have much time before they will begin to die. In general, brain cells can only go about 6 minutes without oxygen.

When a fire is just starting, it is in the incipient stage. At this point, a fire is still able to be controlled or completely extinguished, but it is also well on its way to potentially becoming a larger problem.

Burns come in different levels of severity, with third-degree burns being the worst that a person can have. If someone has skin that is charred, that is a telltale sign that they have suffered from a third-degree burn.

According to NFPA reports, there are around 350,000 house structure fires in the USA alone every year. These start for a number of reasons and can lead to expensive repairs, injuries or worse.

Toggle, slide-gate and compression fire hydrants are all real and exist today. They all fall under the term "dry barrel" as the entire waterline is all under the ground and thus not prone to frost.

According to an NFPA report, about 70% of all firefighters in the USA are volunteers. While there are volunteers in large cities, it is usually the smaller towns that have a volunteer fire department.

While all the listed methods certainly start fires, cooking is the largest contributor to home fires in the USA. Leaving ovens or stoves on is incredibly common and can lead to dangerous house fires.

While it varies from person to person, anyone with a breathing rate between 12 to 20 breaths per minute is usually within the normal range. Any higher or lower than that could be a cause for concern.

Like adults, there is a range that is considered "normal" breathing for infants. In general, that is between 30 and 60 breaths a minute. Any more or less, and you should consider consulting a doctor.
