Has anyone got any thoughts or experiences with regards to prevention of legionella in respect of fire hose reels.

Just flush them through at least every six months

David I work for the fire Service and we have had concerns about this before.
On a recent visit from the HSE we found that some hydrants in the hot weather on the end of "legs" actually had a temperature of 20 degrees. as to your problem we ensure that even our shower heads are run at least once weekly.
A good idea would be to ensure that as much water as possible is expelled from the hose and that it is flushed regularly, I personally feel that every six months is a long time.

Its a question of risk assessment. legionella in a mains fed fire hose which is closed to the air and to which nobody is usually exposed is low risk.
The temperature is a risk factor but regular
flushing of the system will ensure that there is no sludge, rust or scale for the bacteria to feed on and so multiply. Cooling towers and evaporative condensers are the main culprits in an outbreak of infection.

Apologies this is an old one but i've been away. Agree with all that has been said before but we also recommmend that the fire hose is placed into a full bucket of water prior to flushing. The risk with legionella is from inhalation of aerosols, obviously discharging the water this way prevents the formation of aerosols, hence reduces the risk further.
Alternatively the hose should be placed a long way down a dain.

Large, bucket, yes. Down a drain, never if the hose is attached to the mains. You would be contravening water regs, as there is a risk of suck-back if mains pressure failed.
