Burning (no pun intended) question for Guitarpix

Pix,  I have a few burning questions:

Just what is an underwater firefighter? I am in the fire service and have never seen job description or job title such as that.

Does one need special training with hoses?

How does one account for hydraulic lift underwater?

Do you have issues with pump cavitation on hot days or when your tank goes dry?

Just where are the hydrants?

Do the turnouts affect your buoyancy when they get wet?

Do they make Nomex ( or Aramid fiber) wetsuits? If so are they comfy?

Do your fins pull on like bunker boots?

When you use foam is it like diving in a bubble bath?

Many land-based coastal fire departments require a half-mile swim test as part of their physical agility test for prospective firefighters to determine if they are capable of water rescues. Do you require completion of a half-marathon to determine if your firefighters are capable of rescues on land?

Do you have a fire dogfish?

Just wondering...
