Many offices are busy two or three days a week and quiet the rest. Fewer people means fewer flushes, fewer showers and less water running through pipes. That can leave water standing in exactly the conditions legionella bacteria like.
Where quiet offices can go wrong
- Washrooms and kitchenettes used much less than the system was designed for.
- Showers for cyclists and runners that are rarely used.
- Whole floors or wings closed or rarely occupied.
- Hot water systems set up for a bigger workforce.
- Cold water tanks holding more water than the building now uses.
Practical steps
- Review your risk assessment when occupancy changes. A plan for a full building may not suit a half-empty one.
- Flush little-used outlets regularly and record it. See dead legs and little-used outlets.
- Check temperatures in hot and cold systems.
- Consider reducing unused plant and storage with your advisers, so water does not sit for long.
- Keep a logbook and name who is responsible. See who is responsible for legionella control.
- Plan for reopening areas. Our reopening checklist helps.
Your duties
Employers and those in control of premises must manage risks to health under the Safety, Health and Welfare at Work Act 2005. The HPSC national guidelines give practical advice on legionella control.
