This is completely off topic, but here’s some facts for you, from someone who works at a fire department.
Those physical fitness tests were pretty arbitrary. They don’t have much basis in the job itself.
At most departments, physical fitness tests are for the application only, and a LARGE percentage of current firefighters couldn’t pass them just a few years later.
There are many, many jobs a firefighter does, and most of them do not require massive amounts of physical strength.
Firefighters deal with the public, and often in a medical capacity far more often than an extinguishing fire capacity. Having female paramedics available to run medical calls is very important for the community. This is the same for having a mix of employees from all socioeconomic groups that are in the area.
There are a LOT of fire departments that are switching to a more fair entrance criteria, and that is making the job better, not worse.
