DO NOT ATTEMPT TO PULL THE PERSON FROM THE ELECTRICAL SOURCE WITH YOUR BARE HANDS, YOU MAY BE ELECTROCUTED. Remember, your body is a good conductor of electricity, if you touch the person while they are connected to the electrical source, the electricity will flow through your body causing electrical shock.
Small electric shocks may be so weak as to be imperceptible, while severe shocks can cause muscle spasms that make it hard to let go of the electrical source.
Birds sitting on a wire don't touch the ground (or anything in contact with the ground), so electricity stays in the power line. But, if a bird touches a power line and equipment or other metal that is grounded, it gives electricity a path to the ground, and the bird could be shocked.
If you've been shocked
Let go of the electric source as soon as you can. If you can, call 911 or local emergency services. If you can't, yell for someone else around you to call. Don't move, unless you need to move away from the electric source.
87-103), NIOSH notes that electrocution victims can be revived if immediate CPR or defibrillation is provided, typically within 4 minutes of an electrocution, followed by advanced cardiac life support (ACLS) measures within 8 minutes.
Why do people sometimes “freeze” when they are shocked? When a person receives an electrical shock, sometimes the electrical stimulation causes the muscles to contract. This “freezing” effect makes the person unable to pull free of the circuit.
Power lines are not insulated and you should always avoid contact with them. It is quite possible for people to get electrocuted if you touch power lines.
When working on high-voltage circuitry, many electricians like to place one hand behind their back because this way there is little chance for each hand to touch objects of different electrical potentials and cause a shock.
The newly cooled blood in the feet lowers heat loss from the feet, and the warmed blood flowing back into the body prevents the bird from becoming chilled. And because bird circulation is so fast, blood doesn't remain in the feet long enough to freeze.
Electricians usually work with one hand and keep the other at their side or in their pocket, far away from any conductive material. In case there is a water or chemical spillage on the equipment, the other hand can be used to shut power off and unplug the equipment.
The mechanism of death in electrocutions is most commonly a cardiac dysrhythmia, usually ventricular fibrillation, less commonly paralysis of the respiratory muscles, and rarely a direct effect on the brainstem as a result of passage of the current through the head and neck.
Just like women, female birds ovulate follicles (small swellings that rupture) from their ovaries regularly, without any interaction with males. While ovulation leads to menstruation in women, female birds do not menstruate.
Chickens' feet are surprisingly sensitive and are easily injured. Chickens use their feet a lot - even a severe foot injury is unlikely to completely stop a chicken from foraging and roosting - and their feet heal slowly, so minor foot injuries in chickens often develop into more serious problems like bumblefoot.
A bird has a relatively small amount of blood. Typically, about 1/10 of a bird's body weight is blood. So, cockatiels and sun concures, which often weigh around 100 grams, would have about 10 milliliters of blood in their bodies. It's considered life-threatening if they lose more than about 30 percent of that.
Yet, when it comes to the most common injury as an electrician, electrical burns are the most common cause of workers' compensation claims among electricians throughout California. An electrical burn occurs when the skin is exposed to a high voltage electrical current.
Safety Rule #1: Limit workplace access to electrical hazards. Depending on where you work, there may be industrial equipment packed with enormous voltage. Access to electrical components should be by qualified personnel ONLY.
The human body feels a shock when the voltage is higher than about 3,500 volts. Walking over a carpet can generate 35,000 volts. The Electrostatic Discharge (ESD) from this voltage can cause pain. The discharge is not life threatening but it still hurts.
Because both of the bird's feet are on the wire no electricity flows through it. There is no circuit, its two feet are at the same electric potential, and electricity travels along the wire instead of through the bird, so the bird doesn't get shocked. This is probably what you were taught in physics lessons at school.
When a bird is perched on a single wire, its two feet are at the same electrical potential, so the electrons in the wires have no motivation to travel through the bird's body. No moving electrons means no electric current.
Assuming a steady current flow (as opposed to a shock from a capacitor or from static electricity), shocks above 2,700 volts are often fatal, with those above 11,000 volts being usually fatal, though exceptional cases have been noted.
People have stopped breathing when shocked with currents from voltages as low as 49 volts. Usually, it takes about 30 mA of current to cause respiratory paralysis. Currents greater than 75 mA cause ventricular fibrillation (very rapid, ineffective heartbeat).
You should first attempt to turn off the source of the electricity (disconnect). If you cannot locate the electrical isolating source, you can use a non-conducting object, such as a wooden pole, to remove the person from the electrical source. Emergency medical services should be called as soon as possible.
Are eggs cruelty-free? From the caged conditions to the cruel practices of debeaking and male chick maceration, eggs are far from being cruelty-free. Even free-range, backyard, and rescue eggs cause physical and mental harm to chickens.
They form tight bonds with others in their flocks, and create social groups amongst themselves. Chickens do not all get along, however, and chickens will hold grudges against others for various reasons.
