The California condor can soar 15,000 feet above the earth. It has a wingspan of up to 9.5 feet\u2014nearly twice your height! Because of this broad wingspan, power lines are a serious hazard to condors.<\/p>\n

Small birds can sit safely on one power line. They don\u2019t touch the ground, or any other grounded object, so electricity stays in the power lines and doesn\u2019t harm the birds. Condors, with their broad wingspan, are likely to touch a power line and pole at the same time and become a path for electricity to travel down the pole to the ground. Or, their large wings can bridge two power lines at the same time, creating a short circuit. In either situation, the birds are electrocuted.<\/p>\n
Condors have a slow rate of reproduction, which is one reason they nearly went extinct. Power line contacts haven\u2019t helped matters.<\/p>\n
In 1979, only 25 California condors were left and efforts began to save them. Scientists at the Los Angeles Zoo developed a program to train captive condors to avoid power poles before they are released into the wild. A perch that looks like a power pole delivers a mild shock to any bird that touches it. The birds learn to land somewhere else.<\/p>\n
Today, about 504 California condors are living\u2014329 of them in the wild.<\/div>

![\"Danger](\"https:\/\/pgesafetyeducation.com\/school\/wp-content\/uploads\/2020\/06\/high_voltage_fence_sign-200x138-1.jpg\")
When you work outdoors with long or tall equipment (such as ladders and paint rollers), be sure to keep yourself and your equipment at least 10 feet away from all overhead power lines. That includes the service drop wires that go from power poles to buildings.<\/p>\n
If you plan to dig or move earth in any way (even just planting a tree), make sure to call your one-call utility locator service at 811 first so they can mark any underground power lines or other utilities.<\/p>\n
If you see a fallen power line, stay far away, and call 911 and your local electric utility immediately. Even if they are not sparking or humming, fallen lines can shock you if you touch them or the ground nearby.<\/p>\n
Transformers and substations contain electrical equipment that is dangerous to contact. If you see an unlocked transformer, or if you see someone trying to enter a substation, call 911 and your local electric utility immediately.<\/p>\n
You don’t have to be touching the ground directly to conduct electricity. You could also be touching something that is in contact with the ground, like a tree or a ladder.<\/div>

Electricity travels in a loop called a circuit<\/strong><\/span>.\u00a0A circuit has an energy source and wires; it may also have a load and a switch. There must be no breaks in the loop in order for current to flow. A loop with no breaks is called a closed circuit<\/strong><\/span>. An open circuit<\/strong><\/span> has a break.<\/p>\nFour Parts of a Circuit<\/h3>\n
![\"Circuit](\"https:\/\/pgesafetyeducation.com\/school\/wp-content\/uploads\/2020\/06\/circuit-illustration.jpg\")
<\/p>\n
\n- Energy Source – source provides the push that makes current move around a circuit.<\/li>\n
- Load – converts electrical energy to another form, in this case a bulb produces light and heat.<\/li>\n
- Wires – two wires connect the energy source and the load.<\/li>\n
- Switch – A switch in the middle of one wire opens and closes the circuit.<\/li>\n<\/ol>\n
When all parts are connected to form a loop it is a closed circuit. Otherwise, it is an open circuit.<\/p>\n
Your home is part of a large circuit. The generating plant is the energy source, transmission and distribution lines are the wires that connect the plant to your home, the lights and appliances in your home are the load, and on\/off switches on the walls and appliances open and close the circuit.<\/p>\n
