Yes, 450 volts is very painful and extremely dangerous, capable of causing severe burns, muscle contractions that prevent letting go, internal injuries, and potentially cardiac arrest or respiratory arrest, as skin resistance breaks down at this voltage, allowing a significant, harmful current to flow through the body, especially if it crosses the chest. While "volts hurt, amps kill," higher voltage (like 450V) pushes more dangerous current (amps) through your body's resistance, making it much more severe than lower voltages.
Exposure to voltages less than 50V a.c. is generally considered low risk in electrical safety terms. An electric shock at 50V a.c. is unlikely to be fatal, however it can still be painful and may cause a related accident from a reaction to the shock. Voltages greater than 450V a.c. are especially dangerous.
There is no set level that dictates the "lethality" of a voltage. Generally, voltage levels above 50 are considered lethal or potentially dangerous under certain conditions, such as the path of the current and duration.
Voltage levels of 500 to 1000 volts tend to cause internal burns due to the large energy (which is proportional to the duration multiplied by the square of the voltage divided by resistance or the square of the current multiplied by the resistance) available from the source.
Symptoms of shock
Pale, cold, clammy skin. Shallow, rapid breathing. Difficulty breathing. Anxiety.
When an electric shock victim goes into cardiac arrest or ventricular fibrillation, it is important to call for emergency medical support (EMS) and start CPR within 4 minutes and continue CPR until rescue crews arrive. Brain damage and even death can occur if the blood flow is not reestablished within 4 minutes.
Can an electric shock kill you later? Yes, delayed effects are possible with electric shocks. The most likely causes are irregular heart rhythms or infections.
Dr. Michael S. Morse, a professor of electrical engineering at the University of San Diego, explains that while 10,000 volts can be life threatening in certain circumstances, it's possible for something to have 10,000 volts behind it and be relatively harmless.
The darts are connected to the main unit by thin wires that achieve a high dielectric strength and durability given the extremely high-voltage electric current they conduct (typically 50,000 volts, or 2,000 volts under load), which can be delivered in short-duration pulses from a core of copper wire in the main unit.
An electrical shock may cause burns, or it may leave no visible mark on the skin. In either case, an electrical current passing through the body can cause damage inside the body, cardiac arrest or other injury.
The double-circuit 400 kV power transmission line is one of the most powerful electrical installations in the entire power system; at a frequency of 50 Hz, it generates an intense magnetic field.
If someone who has received an electric shock does not have cardiac arrest right away and does not have severe burns, they are likely to survive. Infection is the most common cause of death in people hospitalized after an electrical injury.
A typical lightning flash is about 300 million Volts and about 30,000 Amps.
This current activates nerves under the skin which then cause muscles to contract. When this happens, the contractions produced by the CED override a person's ability to make voluntary movements – the person will not be able to run away or physically attack someone.
950,000 volt electrical current. Wrapped in rhinestone for a sparkling style. Arc spark and crackling sound for immediate intimidation. Safety switch prevents accidental discharge.
Certainly it's OK for a Tyrannosaurus to take a "mild" 10,000 volt shock, probably along with the Triceratops and Stegosaurus due to their thick hides and size, but that type of voltage would likely kill smaller dinosaurs with the exception of Velociraptors, who had attacked the fences multiple times without suffering ...
Well, a lightning is around 100-300 million Volts, but over a very short period, so if you can apply 200mil. Volts over even one second, you are basically guaranteed to oneshot any human.
The human body can withstand a wide range of voltages, but typically, anything above 50 V can be potentially harmful.
When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb. These effects may clear up with time or be permanent. Electric injury can also affect the central nervous system.
When to contact a doctor
Electrocution is a death caused by an application of electrical current to the human body.
Chest compression mimics heart contractions and mouth-to-mouth mimics breathing, by delivering oxygen to the lungs via the mouth. CPR is the second link in the Chain of Survival. It is the link that can buy life-saving time between the first (early access to emergency care) and third link (early defibrillation).
Someone in shock needs fluids fast or they can die. If the person is awake and can drink fluids, help them drink. Also, if you know how, you can start an intravenous drip (IV). In an emergency, an enema can be used instead (see below).
CPR should not be performed in cases of irreversible death, such as when there are unmistakable signs like rigor mortis, decapitation, or dependent lividity. A valid do-not-resuscitate order or advance directive indicating the patient's wish to forgo resuscitation is also a clear contraindication.
The 30/30 lightning rule is a safety guideline: if you see lightning and hear thunder in 30 seconds or less (flash-to-bang), lightning is close and dangerous; seek immediate shelter in a sturdy building or metal-roofed vehicle, not under trees or small shelters, and wait 30 minutes after the last thunder before resuming outdoor activities. This rule helps determine when a thunderstorm poses a direct threat and requires action, preventing injuries during sports and outdoor events.
