The other night I caught a small job in Brooklyn and the first due Engine Chauffeur 219 encountered a frozen hydrant. Following the proper procedure, the Chauffeur transmitted an URGENT for a frozen Hydrant and requested a 10-70. The Second due Engine was on a good hydrant and was able to hand stretch a 3.5" supply line to the first due Engine and was able to supply the Engine that eventually had 2 lines coming off of it.
The First due Engine Chauffeur dropped the tank water and while all of this was going on, the Control man and Chauffeur from Squad 1 were assisting getting the hydrant operational. They ended up using a road flare and sticking it in the barrel of the hydrant and within a minute or two had a positive water source! It was a great heads-up move! The key is to hang the road flare in the barrel through the use of the wire legs, don't just drop it in!
