PG&E are also asking customers to:

• Learn whether their home or business is in or near a high fire-threat area on the CPUC High Fire-Threat District map. Customers also can visit pge.com/wildfiresafety to enter their address and find out if their home or business is served by an electric line that may be turned off for safety during high wildfire threats. • Update their contact information at pge.com/mywildfirealerts or by calling 1-866-743-6589 during normal business hours. PG&E will use this information to alert customers in advance of turning off their electric service for safety, when and where possible. • Prepare for and practice an emergency plan to keep themselves, their families and/or employees emergency-ready and safe during an outage. Keep in mind family members who are elderly, younger children and pets. Information and tips including a safety plan checklist are available at pge.com/wildfiresafety.
