Prepare before an outage
- Keep flashlights, batteries, charged communication devices and emergency contact information available.
- Test smoke and carbon-monoxide alarms and know which systems have battery backup.
- Identify critical equipment, sump pumps, medical needs, refrigeration and safe shutdown procedures.
- For businesses, assign roles for occupants, security, communications and reopening.
Avoid fire and carbon-monoxide hazards
- Use flashlights rather than candles where possible.
- Never use charcoal or gas barbecues, camping stoves or generators indoors.
- Operate generators outdoors and away from windows, doors and vents, following manufacturer and electrical-safety requirements.
- Do not use a gas range or oven as a space heater.
Protect against water damage
- Monitor indoor temperature, vulnerable plumbing and sump systems during extended winter outages.
- If safe, shut off water or winterize systems when directed by a qualified professional.
- After power returns, inspect basements, mechanical areas, ceilings and exterior walls for leaks or failed equipment.
Business continuity
- Document outage times, alarms, temperature conditions, water entry and actions taken.
- Do not reopen until utilities, life-safety systems, equipment and affected areas are safe and operational.
- Use phased reopening when only part of the property is ready.
