When the Power Goes Out: Advice as Isaac Comes Ashore

Michael Bove, vice president for engineering at Hartford Steam Boiler, offers the following advice to protect property if the power goes out.

• Unplug computers, home entertainment systems and non-essential equipment and appliances. This helps prevent surge damage when electrical power is restored.
• Operate portable generators only through a properly installed transfer switch or plug appliances directly into the generator using a properly rated extension cord. 
• Do not connect a generator to a home's electrical system which can feed power onto exterior power lines and cause an electrocution risk to utility employees 
• Do not run portable generators in enclosed spaces such as a garage to avoid the danger of carbon monoxide.
• Limit opening refrigerator and freezer doors. Food will keep longer if doors remain closed. If the power is out longer than two hours, throw away food that has a temperature higher than 40°F.
• Do not use charcoal or gas grills or camp stoves for cooking in enclosed areas.
• Stay away from downed power lines.  Always assume the lines are “live.” Call 911 to report any downed lines.
• Homeowners with automatic garage door openers should check the manufacturer's instructions to learn how to open the door manually.
