A water reserve needs to account for hygiene as well as drinking. During an interruption, think through when hands, utensils and surfaces need cleaning. Buying a bottle of sanitiser is useful preparation, but it does not remove every need for appropriate washing and safe food handling.

Identify the important moments
Food preparation, toileting, care tasks and handling waste each need attention. Keep relevant supplies easy to reach and follow product instructions. If a water notice is in force, check which water can be used for the task. Do not use an unknown source simply because the activity is not drinking.
- Keep food preparation away from waste and dirty equipment.
- Make supplies reachable for the intended person.
Reduce unnecessary preparation
Choose suitable ready-to-eat foods that require little handling, while preserving normal safety standards. Use clean utensils and appropriate portions instead of preparing large quantities that cannot be safely stored. Keep original labels so you can check whether a product needs refrigeration after opening.
Ask about specific care needs
Some care routines need particular hygiene arrangements that a general household checklist cannot specify. Discuss these with the responsible professional before an outage. Store enough relevant consumables within their instructions and know whom to contact if supplies or water become unavailable. If hygiene conditions at home become unsafe, seek advice and support early. Do not mix cleaning chemicals or improvise disinfectant concentrations to compensate for a lack of water; follow the applicable product and public-health guidance.
