What are the 5 types of electrical incidents?
That being said, there are six main types of electrical burns: arc burns, low voltage burns, high voltage burns, oral burns, flash burns, and flame burns .
What are three causes of electrical injuries?
- Accidental contact with power outlets, power cords, or exposed parts of electrical appliances or wiring.
- Flashing of electric arcs from high-voltage power lines.
- Lightning.
- Machinery or occupational-related exposures.
What is the most common electrical injury?
Electrical burns are the most common shock-related, nonfatal injury. They occur when a worker contacts energized electrical wiring or equipment. Although electrical burns can occur anywhere on the body, they most often occur on the hands and feet.
What are the common electrical accident?
Electrical Accident Causes
Old wiring . Electric cords that run under carpeting. Flammable materials left near exposed electrical wiring in the workplace. ... Poor wiring: substandard wiring can lead to electrical fires and electric shock.
How electrical accident can be avoided?
Stay away from wet locations
It’s not safe to go near the water with electrical equipment. Wet locations such as kitchens, baths and utility rooms – as well as grounded areas like your basement or garage – require outlets protected by Ground Fault Circuit Interrupters, or GFCIs.

What are the 2 known hazards of electricity?
The main hazards with electricity are: contact with live parts causing shock and burns . faults which could cause fires ; fire or explosion where electricity could be the source of ignition in a potentially flammable or explosive atmosphere, e.g. in a spray paint booth.
Which organ is mainly affected by electric shock?
An electric shock may directly cause death in three ways: paralysis of the breathing centre in the brain , paralysis of the heart, or ventricular fibrillation (uncontrolled, extremely rapid twitching of the heart muscle).
What are the four most common types of electrical injuries?
There are four main types of injuries: electrocution (fatal), electric shock, burns, and falls . These injuries can happen in various ways: Direct contact with exposed energized conductors or circuit parts.
What happens when current passes through human body?
The contact with electric current can have various effects on the human body such as pain, burns or even death. ... The other reason when current passes through your body, it is transformed into thermal energy . This can cause serious burns, both inside your body and on your skin.
What is the human body resistance to electricity current If skin is wet?
Human resistance is about 10,000 ohms on the high side and as little as 1,000 ohms if the person is wet. Remember, ohms is the unit of measure of a material’s resistance or impedance to current flow. Current flow is obviously higher as the resistance goes down.
Can you get electrocuted and not feel it?
Delayed electric shock symptoms should not be ignored because they may be signs that a person has suffered a serious electric shock injury. If you experience these symptoms after contact with an electrical source, you should see a doctor.
What is electrical resistance of human body?
The internal body resistance is about 300 Ω , being related to the wet, relatively salty tissues beneath the skin. The skin resistance can be effectively bypassed if there is skin breakdown from high voltage, a cut, a deep abrasion, or immersion in water (Table 2).
