How hot should hot water be in a public place ?
Discussion
Went to a pub.
The hot water coming out of the hot water tap in the gents was f*ckin hot. Seriously f*ckin hot. There was steam coming out of the tap.
People were warning each other as they came and went.
I made a comment to the landlord and clearly many people had also before, as he had this long reply which he had clearly said many, many times.
Something to do with 'its all your fault with all your rules and regulations' - (he was a South African), bla, bla, bla....
He said it had to be at least 95 degrees to kill any chances of legionnaires disease and other things.
Does this sound right ? There must be some health and safety levels I'm sure in a public place. But this was near scalding !!

This is something I've noticed as well. I have Invisalign aligners and have to brush my teeth and my aligners after everytime I eat or take them out with cold water. Due to this, I'm always visiting public toilets when I'm out and the amount of times I struggle to get water that's doesn't actually melt or ruin my trays is staggering.
1st world problems.

Legionella is killed off at 60 Celsius, thermostatic mixers should be used to bring that down to circa 40 for a hand basin.
50 degrees actually. Cold has to be below 20 and hot above 50, but the hot can't be more than (I think) 45 degrees out the tap in a primary school (I work in an all through school).Antony Moxey said:

At 50 is can take over two hours to kill off the bacteria so if water is coming from a contaminated tank into a boiler which heats and supplies the water within that time it is potentially a problem. 44 degrees is the standard for hot water - based on the fact that you can bathe in it and not boil to death, Hot water should be brought up to 60 degrees overnight to kill Legionnella, but it's a moot point really - when did you last hear of someone catching Legionnaire's disease?
H&S rules still dictate this, and also that "hot" water should be no more than 44 degrees - anywhere that the public have access to should have a TMV to mix hot and cold water down to that temperature.
I have one in my own bathroom - not for safety reasons, but so that I can lie in bed and say "Alexa, run the bath" and have it ready for me to sweat out a hangover. A decent mixer is adjustable up to around 60 degrees, and you can lock it down with an allen key to stop it being messed with. If the cold water to the mixer stops, it'll shut off the hot side so nobody gets burnt.
Or their Invisalign trays melted.
Sounds like the Saffy doesn't quite understand the law!

Water needs to be above 90 to kill legionnaires instantly. It will kill it over 50 but over longer periods of time.
There are so many types of hot water systems available that it’s not a one size fits all solution. I’m sure the water has to run above 40 within a minute (might be less but it’s Saturday night and the beer has won), no company has ever ran a system constantly for an hour to see what happens. They just don’t care that much.
Legionnaires risk from a tap is slight. There might be showers on site that need to comply hence the situation. Most risk assessment companies only want to tick the temp box so just indeed tick the temp box.
