Can You Touch Hydro Lines?

In 2012, a hydro line snapped near Brazil’s biggest hydroelectric plant, killing 10 workers. The incident brought renewed attention to the dangers of hydroelectric transmission systems, which carry massive amounts of electricity at high voltages. Our homes are powered mostly by hydroelectricity, but few of us understand the very real hazards posed by the transmission lines that bring it to our plugs and sockets.

This article examines why it’s so dangerous to touch hydro lines or get too close to them. We’ll look at myths and misconceptions, warning signs, safety procedures, and how to protect children. By the end, you’ll have a thorough understanding of hydro lines and why they should always be treated with caution.

What Are Hydro Lines?

Hydro lines, also known as power lines or transmission lines, are cables and wires supported by utility poles that are used to distribute electricity over long distances (source: They are an essential part of the electrical grid, transporting electricity from power plants to substations where the voltage is decreased before entering homes and businesses (source:

Hydro lines consist of aluminum or copper conductors that are usually uninsulated. Insulators separate the wires from the poles and prevent electricity from flowing into the ground (source: Transformers may also be present along power lines to step down voltages to safer levels before the electricity enters residential areas.

Overhead hydro lines can operate at high voltages from thousands to hundreds of thousands of volts. The higher the voltage, the more power that can be efficiently transmitted over long distances. Long distance transmission lines operate at extra high voltages of 765,000 or more volts (source:

Dangers of Touching Hydro Lines

The most imminent danger of touching hydro lines is the risk of electrical shock or electrocution. Hydro lines carry extremely high voltage electricity that can easily flow through the human body (Source: Even brief contact with a hydro line can result in severe injury or death.

When a person touches a live hydro line, electricity will flow through their body, causing severe internal burns and muscle contractions. At high voltages, this can stop the heart and lungs, resulting in cardiac arrest and death. The amount of damage depends on the voltage – distribution lines carry 7,500 to 34,500 volts, while transmission lines carry as much as 500,000 volts (Source:

Touching hydro lines does not always result in electrocution. However, the electrical shock can still cause severe burns, neurological damage, and trauma injuries from falls or muscle contractions. Any contact with live power lines can be extremely dangerous.

Why You Should Never Touch Hydro Lines

Despite appearances, you should never touch or interact with power lines, even if they seem harmless or “dead”. Power lines carry
extremely high voltage electricity that can seriously injure or kill anyone that comes into contact with them.
According to the American Public Power Association, touching a power line can result in severe
burns or electrocution. Power lines are not insulated like electrical wires inside your home.

This dangerous high voltage electricity can arc or “jump” to your body from several feet away. Even getting close is extremely unsafe.
You do not actually have to touch a power line to be electrocuted. Simply getting near high voltage can allow the electricity to “jump” through the air to your body.

Additionally, power lines carry huge amounts of electric current. Your body simply cannot withstand thousands of volts of electricity surging through you.
If you do touch a power line, the massive electric shock will likely cause severe injury or death. Do not risk your safety by interacting with power lines.

Myths and Misconceptions

Many people assume that since birds can often be seen resting on power lines, it must be safe for humans to touch them as well. However, this is a dangerous myth. Birds are able to sit on power lines safely because they do not provide a path to the ground to complete an electrical circuit. Humans touching a power line would complete a circuit and be electrocuted.

Another common misconception is that the power lines on wooden utility poles are safe to touch. While transmission lines on tall metal towers are uninsulated, some believe that the lines on smaller poles must be insulated. This is not the case. Nearly all power lines are uninsulated, regardless of the type of pole, and contact should always be avoided.

Touching any power line, energized or not, insulated or not, is extremely hazardous. Even if a line has fallen or seems disconnected, there is a possibility it could become re-energized at any moment. Downed lines should always be reported immediately, but never approached or touched.

Safe Distances from Hydro Lines

When working or operating equipment near overhead power lines, it is crucial to maintain a safe distance to avoid contact. Here are some general guidelines for safe distances from hydro lines (Texas Department of Insurance):

  • For power lines up to 50,000 volts, stay at least 10 feet away.
  • For power lines over 50,000 to 200,000 volts, stay at least 15 feet away.
  • For power lines over 200,000 to 350,000 volts, stay at least 20 feet away.
  • For power lines over 350,000 to 500,000 volts, stay at least 25 feet away.
  • For power lines over 500,000 to 750,000 volts, stay at least 35 feet away.
  • For power lines over 750,000 to 1,000,000 volts, stay at least 45 feet away.

Required safe distances may be greater for certain activities like construction, tree trimming, excavation, equipment operation, etc. Consult local regulations and utility providers for specific clearance requirements.

Maintaining proper clearance distances is crucial for safety around hydro lines. MNSHO provides more guidance on occupational safe distances from power lines ( … pdf).

What To Do If a Line is Down

If you see a downed power line, stay at least 30 feet away and do not approach the line or anything touching it, as it may still be energized (FirstEnergyCorp). Downed lines can carry an electric current strong enough to cause serious injury or even death.

Call 911 and your local electric utility company immediately to report a downed power line. The utility company will send a crew to safely secure the power line (Angi). Do not attempt to move or drive over a downed power line yourself.

Warn others nearby to stay away and wait in a safe area for the utility crew or first responders to arrive and handle the situation. Do not try to move a downed line or remove debris yourself even if you think the line is de-energized, as it could become re-energized at any moment.

Protecting Children

Teaching children about the dangers of hydro lines and electrical equipment is crucial to keeping them safe. Accidents often occur when kids don’t realize the risks involved with things like climbing trees near lines or playing near transformers. Parents and caregivers need to have open and honest conversations about electrical safety.

Specifically, children should be taught the following power line safety rules:

  • Never fly kites or climb trees near power lines. Contact can be deadly.
  • Don’t build treehouses or playhouses near power lines or electrical equipment.
  • Never touch a downed power line. Stay far away and tell an adult immediately.
  • Don’t plug too many devices into one outlet. Overloads can cause fires.
  • Keep electrical cords safely out of reach of children and pets.

Setting clear expectations and having ongoing conversations are key. Children should understand that power lines and equipment are dangerous and must always be avoided and respected.

Warning Signs

Power companies post warning signs near hydro lines and electrical infrastructure to caution people about potential dangers. According to Overhead Power Line Signs, common signs include:

  • “Danger: High Voltage” – Warns about nearby high voltage equipment
  • “Caution: Overhead Power Lines” – Indicates overhead power lines in the area
  • “Danger: Keep Back” – Cautions people to maintain a safe distance
  • “Danger: Do Not Touch” – Warns not to touch power lines or equipment
  • “Danger: Downed Power Lines” – Signals fallen or low-hanging power lines

These signs are intended to protect the public by making people aware of electrical hazards in the vicinity. Heeding their warnings can prevent electrocutions and injuries. If you see these types of cautionary signs, be sure to keep a safe distance from any overhead lines or electrical infrastructure.


Touching hydro lines can lead to serious injury or death. Even coming into close proximity of hydro lines can be extremely dangerous. Never assume that a downed line is safe or dead. Always stay at least 10 meters away from any hydro lines, and call emergency services if you see one that is damaged or on the ground. Teach children about electrical dangers and put up warning signs on your property if you have overhead power lines. While hydro lines may seem harmless, they can electrocute you within seconds if you make contact. Your safety around electricity is up to you. Avoid hydro lines at all costs to protect yourself, your family, and your community.
