When a boil water notice affects a food business, stop and control every use of tap water that could affect food safety. That includes food and drink preparation, ice, food-contact cleaning, utensil washing and water-fed equipment. Record when the notice started, what products and processes may be affected, the controls introduced, every stock decision and the checks completed before normal operation resumes.
The answer in 30 seconds
FSAI guidance says tap water used for food preparation or cleaning food-contact surfaces, equipment, crockery and utensils must be boiled during a boil water notice. Hot tap water is not a substitute. Use properly boiled and cooled water or a suitable bottled supply, stop equipment that cannot make the water safe, assess food, drinks and ice made before the notice, and contact the environmental health officer if the site cannot operate safely.
When the notice is lifted, do not simply reopen every outlet. Follow the specific official instructions, clean and disinfect water-using fixtures and equipment, rinse them, verify the restart and record who authorised it.
TapTick can help teams assign incident checks, capture product decisions and corrective actions, and keep restart evidence visible across sites. See the TapTick features.
What should happen first?
Treat the notice as a food safety incident, not just a facilities message. The person in charge should confirm the affected supply area and the time the notice took effect, then prevent unsafe water from continuing to enter food, drinks, ice or cleaning processes.
- Verify the notice: use the official notice or supply update, not a social-media post or second-hand message.
- Identify affected sites: confirm which premises, buildings, kiosks, kitchens and concessions use the affected supply.
- Stop uncontrolled water use: label or isolate outlets and disable affected water-fed equipment where staff could use it by habit.
- Protect food and customers: hold any food, drink or ice whose water history is uncertain until an authorised decision is made.
- Introduce the alternative: define where boiled or bottled water will come from, how it will be stored and which tasks it may support.
- Brief every shift: give staff one clear instruction covering preparation, cleaning, handwashing, equipment and escalation.
- Contact the regulator where needed: FSAI advises businesses to consult their inspector when unsure, and to discuss whether continuing to operate is feasible if the water supply is cut off.
Record the time each action was completed. A later note saying “staff told” does not show whether an ice machine continued running for an hour after the notice arrived.
Which uses of water are affected?
FSAI guidance says tap water must be boiled when it is used for:
- food preparation;
- cleaning surfaces or equipment that may come into contact with food or drink; and
- cleaning crockery and utensils.
The same control needs to reach less obvious uses. Review water added to recipes and concentrates, beverage dispensers, ice makers, produce washing, probe-cleaning arrangements, cloths, spray bottles, dishwashers and any process supplied directly from the mains.
FSAI says bringing tap water to a rolling boil kills harmful bacteria and warns that water from the hot tap is not safe to use as a substitute. Boiled water may be cooled and stored in a clean, covered container in a cool area for up to 48 hours. Label the container with its preparation time and discard time so different shifts do not guess.
Bottled water may support some tasks, but it is not a complete operating plan. The site still needs enough safe water for the volume of food preparation and cleaning, suitable storage, controlled decanting and a way to prevent untreated water being used accidentally.
What about food, drinks and ice already made?
Do not automatically approve or discard every item. FSAI says the business must carry out a risk assessment and determine when the food, drink or ice was made relative to the issue of the notice.
For each affected product or batch, establish:
- what water was used and whether it came from the affected supply;
- when it was prepared, made into ice or dispensed;
- whether the timing was before or after the water may have become unsafe;
- whether a later validated heat treatment would make the product safe;
- whether the product has already been served, sold or transferred;
- which customers or sites may have received it; and
- what the environmental health officer or other competent authority has advised.
Keep affected stock isolated while the decision is pending. Record the product, quantity, batch or preparation time, decision, reason, person authorising it and final disposition. If potentially unsafe product has left the business, escalate promptly under the food incident and traceability procedure.
Ice deserves explicit attention. Emptying the visible ice bin is not enough if an automatic machine remains connected and immediately makes another batch. Stop production, identify ice already distributed to bars or counters, and include the machine in the restart clean.
Which equipment needs to stop?
List every appliance connected to the affected water supply. Depending on the site, this may include ice machines, post-mix dispensers, coffee machines, water coolers, slush equipment, combi ovens, dishwashers and automatic produce-washing systems.
Do not assume that equipment heats water enough. FSAI says a coffee or tea machine should only be used where the water reaches at least 75°C; otherwise it should not be used during the notice. For other equipment, check the manufacturer information and official advice rather than applying the coffee-machine figure by analogy.
Use a simple equipment status:
- stopped and isolated;
- approved for restricted use under a documented safe method;
- supplied with a verified alternative water source; or
- awaiting technical or regulatory advice.
Attach a clear physical sign or lockout where necessary. A message in the manager group is not enough if a new employee can still press the dispense button.
How should staff wash their hands?
FSAI's boil-water-notice guidance says handwashing may continue with tap water when antibacterial soap is used, followed by hand sanitiser. It also stresses that sanitiser must only be used on clean hands because it does not work effectively on dirty hands.
Make that temporary method clear at each handwash point and keep the required soap and sanitiser available. Follow any different or additional instruction in the specific notice or from the environmental health officer. A sanitiser-only instruction is not a substitute for handwashing.
What should the incident record contain?
A useful record should let a manager, inspector or head office reconstruct the full response. Include:
- the issuing authority, affected area and notice reference or source;
- the time the notice was issued, received by the business and communicated to each site;
- the sites, kitchens, counters and water supplies affected;
- the person in charge and escalation contacts;
- taps, equipment and processes stopped or restricted;
- the approved alternative water source and boiling, cooling, storage and labelling method;
- food, drink and ice assessed, including batch, quantity and preparation time;
- stock decisions, disposal, isolation, withdrawal or other action;
- temporary cleaning, utensil and handwashing arrangements;
- staff briefings, shift handovers and signs placed;
- advice received from the inspector, supplier, water authority or equipment manufacturer;
- checks during the disruption and any failure or corrective action;
- the official lifting of the notice; and
- flushing, cleaning, disinfection, rinsing, equipment restart and management verification.
Keep original times and decisions. If an assessment changes after new official information arrives, add the later decision and reason rather than overwriting the earlier record.
Can the business stay open?
It depends on whether the business can operate safely under the notice. FSAI says a business may need to reduce or cease trading for the duration of a water-supply disruption, and that operating without a water supply is very difficult. If the supply is cut off, the operator should contact the environmental health officer to discuss whether continuing is feasible.
A decision to stay open should consider:
- whether there is enough safe water for the entire operating period;
- whether food-contact cleaning and utensil washing can be completed safely;
- whether handwashing controls remain effective;
- whether the menu can be reduced to controlled items;
- whether affected equipment can be isolated reliably;
- whether vulnerable consumers are served;
- whether staff can sustain the temporary method during busy periods; and
- whether the inspector has placed any conditions on operation.
Do not let commercial pressure turn an emergency control into a paper exercise. A smaller safe menu or temporary closure is better than a process that only works while a manager is watching.
What should happen when the notice is lifted?
Confirm the lifting through an official source and follow any site-specific instruction from the HSE Department of Environmental Health, Uisce Éireann or another relevant agency. A forwarded message or assumption that neighbouring premises have reopened is not sufficient.
FSAI advises businesses to clean and disinfect water-using fixtures and equipment, including ice and drinks machines, and rinse them well before reuse. Build the restart around a checklist:
- record the official lifting time and source;
- brief the person in charge and every affected work area;
- follow official flushing instructions;
- clean, disinfect and rinse taps, food-contact systems and water-fed equipment;
- discard temporary stored water and any ice or product that is not approved for use;
- replace filters or follow manufacturer restart instructions where required;
- verify that equipment is operating normally;
- remove signs or isolation controls only after the relevant check passes; and
- record management release and any follow-up action.
Do not mark the incident closed merely because mains water has returned. Closure should mean the food and equipment decisions are complete and the site has verified a safe return to normal controls.
How should multi-site operators manage the incident?
A notice may affect some sites, part of a site, or premises supplied through different water systems. Head office should maintain one incident view without assuming that every location has the same status.
For each site, show:
- whether it is inside the affected area;
- when the site acknowledged the notice;
- which processes and equipment are stopped;
- whether it is open, trading on a reduced menu or closed;
- which food, drink or ice decisions remain unresolved;
- whether the inspector has been contacted;
- when the notice was officially lifted for that supply; and
- whether the restart checklist and manager verification are complete.
Use a controlled core procedure, but keep the official notice, local advice and decisions attached to the individual site. One area's notice may be lifted before another's, and a site with a private supply may have different responsibilities.
Legal duty, official guidance and site procedure
Food businesses are responsible for ensuring water used directly as an ingredient or indirectly in food preparation, processing and cleaning meets food-law requirements. FSAI states that the operator must maintain and verify the quality of the water supply used by the business and have controls to identify, monitor and rectify water-supply issues.
The detailed actions in FSAI's boil-water-notice page are official operational guidance. The specific public notice and instructions from the competent authority remain important because the cause, area and restrictions may differ between incidents.
The business's HACCP-based procedures should turn those requirements into site actions, monitoring, corrective action and suitable records. Review the procedure after the incident if staff could not identify affected equipment, safe water ran short, stock history was unclear or restart evidence was incomplete.
Keep the water incident and every action connected
Use TapTick to assign incident checks, record stock and equipment decisions, and keep corrective actions visible until the site has verified a safe restart.
