    Power Line Safety

    Power lines can be dangerous, especially when they fall. Follow these guidelines from PWP to ensure you stay as safe as possible around power lines:

    General Power Line Safety Tips  

    • Never attempt to retrieve an object that is on or near a power line. Instead, contact PWP immediately at 626.744.4673 to report the issue.
    • Use mylar balloons, kites, and remote-control toys far away from power lines to avoid potential power outages, fires, and serious injuries.
    • Secure helium-filled mylar balloons with weights to prevent them from coming into contact with power lines.
    • Use caution before lifting ladders to avoid accidental contact with power lines.
    • Never attempt to trim a tree near a power line. If you see a tree branch or limb that is dangerously close to a power line, contact PWP at 626.744.4005.

    Fallen Power Line Safety Tips 

    • If you see a fallen, or “downed”, power line, always assume it is live and do not touch it.
    • Avoid touching anything or anyone that has been in contact with a fallen power line.
    • Keep children and pets away from fallen power lines.
    • Call 911 immediately to report a fallen power line. 

    Cars and Fallen Power Lines 

    • Never drive over a fallen power line.
    • If your car comes in contact with a fallen power line, stay inside. The ground outside the car may potentially be energized.
    • Sound your horn to call for help and to inform others of the potential danger.
    • Call 911 and wait until responders assure you that it's safe to get out of your car.
    • If your car has made contact with a fallen power line and a fire starts, remove loose items of clothing and keep both feet close together while shuffling away from the car.
    • Do not pick up your feet or touch the vehicle. 

    Portable/Emergency Generator Safety

    Please keep the following safety tips in mind if you are considering using a portable generator:

    • Have a licensed electrician do any wiring needed to connect the generator to electric circuits. Read and understand the manufacturer's instructions before your generator is connected to your electrical circuits. Plug electric appliances into the generator using a heavy-duty extension cord.
    • DO NOT connect the output of your generator directly to your house wiring or service panel. This can create electrical back feed to the PWP distribution system and put field service crews in jeopardy of receiving severe or fatal electric shocks.
    • To notify PWP of a generator location, please call PWP Customer Service at 626.744.4005.
    • Warning!! Improper use and connection of a back up or portable generator can be a safety hazard. If you have an electric generator that is, or can be, connected to your electrical wiring, state law requires you to notify PWP of its location. Violators can be subject to fines up to $500 or six months' imprisonment (Section 119090 of the California Health and Safety Code).

    Tree Trimming & Power Lines

    Tree trimming is done by utilities to protect the electrical power lines. State law also requires utility companies to maintain specific clearances (depending on the voltage) between electric lines and all vegetation. Here are some additional reasons for pruning and removing trees near high voltage power lines:

    • Public Safety - to prevent injury to people climbing or working in trees adjacent to power lines.
    • Fire Safety - trees in contact with high voltage power lines can act as an ignition source of fires.
    • Reduce Outages - trees represent one of the largest causes of power outages in California.

    Homeowner prevention can help prevent electric outages, fire, and public safety hazards by:

    • Plant the right tree in the right place. If you must plant trees near power lines, make sure the maximum mature tree height is ten feet away from the closest power line.
    • Trees should be selected so they can reach their full height without the need for frequent trimming.
    • Never allow children to climb trees growing near power lines
    • Never prune trees near electric lines. Call the utility company first to inspect the trees. In many instances the utility may perform the tree work at no cost to the homeowner.
    • Inspect the trees on your property annually for hazards. For expert advice on tree health or hazards consult an International Society of Arboriculture Certified Arborist.


    Water-Related Safety Information

    • If you experience a water emergency, please call 626.744.4138.  
    • If you must use tap water during a water emergency, make sure your water has been disinfected by boiling it for 5 minutes or you can use water-disinfecting tablets (4 tablets per gallon), tincture of iodine (12 drops per gallon) or liquid chlorine (8-10 drops per gallon). After treatment, mix the water thoroughly and let it stand for 30 minutes before use. 
    • If your home is served by a sewage system, your drain is an entrance to your wastewater disposal system and eventually to a drinking water source. Discharges from septic tank drain fields may pollute groundwater. Visit the Public Works Hazardous Waste page for information on the disposal of hazardous products.
    • Use cold water instead of hot water for cooking. Hot water is more likely to contain rust and lead from your household plumbing and water heater.
