Does anyone have an example of the above they would be willing to share. Thanks in advance.

As per hopeful's comment, it really is difficult to just say 'office' and have a generic RA.

But in order to be of some assistance:

Consider the water assets at the office - incoming water source, tanks, pipework, outlets like taps and showers, fountains, vending machines, TMV's, etc.

Now for each of these and/or the systems they are involved with consider:

Potential for contamination
Potential for amplification
Potential for transmission
Exposed population
Host susceptibility

Contamination is hard to avoid but I'd hope you can in some way define the others.
Amplification is largely controlled by controlling temperature as either hot or cold.


I'm wary of overstating the above because MOST offices are on mains supplied water with general low risks due to small pipework runs etc.
However...
This could be a huge office in an old building.
There can easily be stagnating areas of water due to out of use areas, poor turnover, poor plumbing. Temperatures in unlagged pipework can rise/fall.
And you might have a large amount of over 60's male workforce who all smoke and drink.
and so on...


This is why you can't really automatically have a simple template RA ... but the above 5 factors are from the BS8580 for legionella risk assessment and competently considering those areas for all your water assets (particularly if uncomplicated and straightforward) should be sufficient. <insert caveat/disclaimer here>
