Guam Power Authority (GPA) advises the public that high winds can cause trees and branches to fall. Take a look around your property and remove damaged trees and overhanging branches to keep you, your property, and power lines safe.
Lawn furniture, canopies, garbage cans and other items can become projectiles in high winds. Secure all lightweight objects and anchor any items that may become airborne. Clear clogged rain gutters of debris to prevent water damage to your property. Install typhoon shutters or board up windows with 5/8” exterior grade or marine plywood.
If you need to evacuate to an emergency shelter, before you leave home, shut off your incoming electricity at the main breaker or switch, usually located by the electric meter or in the circuit breaker panel.
If you are dependent on an electrically-powered life support system, consider having a backup generator. Otherwise, make plans ahead of time to go to an alternate location where electricity will be available such as hospitals. Be prepared to take your medical equipment and medications with you.
To protect your electric equipment from power outages and fluctuations caused by tropical storms, unplug unnecessary and sensitive electronic equipment. Use high-quality surge suppressors for electric appliances that remain plugged in.
GPA further advises customers operating generators for either residential or commercial purposes, especially a large generator, to please SHUT OFF THE MAIN CIRCUIT BREAKER(S) OF ALL HOUSE(S) OR BUILDING(S) THAT ARE CONNECTED TO YOUR GENERATOR. Also, when operating personal generators to service homes or businesses, customers should ensure that it is operating in an open, well ventilated area to prevent adverse effects from inhalation of fumes. For your personal safety and the safety of your family members or employees, double check and make sure that your generator is not in an enclosed area or located next to your air conditioner's air intake and/or other air ducts leading into the dwelling areas in your homes or establishments.
