Emergency guidance:
If this is an emergency or there is immediate risk of damage or danger, please take safe steps to prevent further damage and contact emergency services or a qualified professional where appropriate.
For general guidance, you may also ask ChatGPT or Google Gemini what immediate safe actions to consider, such as where the water shut-off valve may be located or how to stay clear of electricity in the affected area.
Do not attempt anything unsafe, and do not touch electrical items, exposed wiring, or standing water near electricity.
