List hazards and dependencies: power, water, sanitation, ventilation, booking access, staff availability, and safe entry or exit. Consider both immediate danger and business interruption. Identify the services affected by each dependency. The purpose is not to promise that every disaster is preventable, but to make decisions and responsibilities clear before pressure arrives.

Define who calls emergency services when needed, who guides evacuation, who assists people requiring support, and who communicates with clients. Keep exits and routes usable. Staff should know the location of the site plan and receive appropriate training. This online lab is not first-aid, CPR, fire-response, or hazardous-material certification. In immediate danger, contact emergency services and follow trained responders.

A water, drainage, power, or ventilation failure may make some or all services unsafe or noncompliant. Stop affected services, secure the area as appropriate, and contact qualified professionals. Do not improvise a workaround simply to finish appointments. Preserve factual information and obtain guidance from relevant authorities or insurers where required.

Maintain appropriate secure backups and a tested way to access essential business information during an outage. Use approved payment processes; never write down full card details as an improvised workaround. Give clients a factual update, options, and the next expected communication time without exposing other clients’ information. Avoid promising a reopening date before it is supported.

Confirm essential systems, safe conditions, staffing, and any required approvals before restarting affected work. Document repairs, testing, decisions, and follow-up. Review the incident with the team: what worked, what was unclear, and what should change? Test the revised plan through a tabletop exercise rather than waiting for another real event.
