After a recent audit we received some negative comments on our lack of a risk assessment for Legionella. I wasn't aware we actually had to do one based on the facilities we have.
We have office and workshop facilities; no showers, no stagnant water, no air conditioning units, water coolers or towers etc etc. It's just all fed by domestic supply.
Anyone care to comment on what we need to do or have a generic example for a similar setup?
Help!!

Sounds like you've done the risk assessment in your head - just write it down - to demonstrate you have no significant risks! One potential problem you don't mention is 'dead legs' in your domestic water pipework - but if there is no means of aerosol generation downstream, then there should still be no significant risks?

Turtle, you have hot and cold water systems, therefore you have risk. COSHH applies and L8 provides specific guidance.
The degree of risk depends on the age and condition of your storage and distribution systems, temperature of hot and cold systems and if there are any little-used outlets.

No dead legs and all water supplies regularly used on a daily basis.....to fill the kettle. Have just had it confirmed that both office and workshops are on domestic mains supply as well and not being fed from holding tanks.
No shower's, no air conditioning unit and no storage tanks etc etc. We have standard toilets and kitchens in office area which are relatively new, sinks in workshops for filling kettles and no toilets as these are in a block run by facility owner.
Do we need an assessment? Very confused as recent audit said we had to have one. The facility owner is equally confused.

Turtle,
Ron is right I think; you have H&C water with outlets, therefore there is a risk (albeit small), so you need to document the RA you have probably already done. Make sure you are familiar with L8 and don't over-complicate it, but do it and write it down. One reason for doing it is just to be sure that you understand what is happening under normal conditions so you know what to do in the event of the unusual,
John

Do you have a schematic for the pipework?
Are all valves/ equipment identified?
Are all strainers identified?
Are all pipes insulated?
Is the incoming cold supply less than 20 deg?
Is the distributed hot above 50deg?
Is there a hot water cylinder / calorifier?
Is the water heated to above 60 deg?
Are there tmv's on site?
If so are they maintained?
Are they they correct type?
Is the pressureon he hot and cold similar?
