In our industrial society, electricity is the most widely used form of energy. Workers are required to use electrical equipment. This implies that any business can be faced with an accident of electrical origin. If the number of accidents related to electricity decreases regularly, they are often very serious.
The electrical risk includes the risk of contact, direct or otherwise, with a bare live part, the risk of short-circuit, and the risk of an electric arc. Its consequences are electrification, electrocution, fire, explosion ...
The prevention of electrical risk is based, on the one hand, on ensuring the safety of electrical installations and equipment and, on the other hand, on compliance with safety rules when using them or when operating on or near them. electrical installations.
What is a typical checklist to ensure electricity security?
Avoid plugging multiple devices into one outlet.
To disconnect a cord, pull on the plug rather than on the cord itself.
Avoid disconnecting the power to an appliance by abruptly pulling the cord out of the outlet.
What is electrical safety?
It is important to remember that electricity is always a possible source of danger. ... The rule of thumb is simple: assume all electrical equipment and all electrical wires are live until proven otherwise.
What are the electrical safety rules?
Do not touch an uninsulated or stripped cable until you are sure there is no voltage. Do not approach an overhead conductor that has fallen to the ground without being authorized to do so. The emergency cut-out is used to cut off the current in the event of a danger to the safety of persons and equipment.
What systems protect people from electrical risks?
Different systems
The basic protection to protect against electricity is isolation. This isolation is achieved by a layer of insulating materials on the wires, cables and, a confinement of any electrical or electronic circuit in a rigid and dielectric envelope.
What are the dangers of electricity at home?
According to the National Electric Safety Observatory (), out of the 7 million housing units at risk, 30% are considered particularly dangerous. The consequences can range from a simple blow of juice to electrocution, including an electric fire.
What are the dangers of electric current for the human body?
rapid contact with medium current : tingling; limit of not letting go; tetanization; burns (internal and external); asphyxia by tetanization of the respiratory muscles.
What precautions should be taken to avoid any electrical accident?
Here are 5 good practices that are very easy to implement.
Secure your electrical outlets.
Respect the capacity of your electrical outlets.
Unplug any extension cords .
Avoid contact between the water and electricity
Monitor your devices and installations.

What are the causes of an electrical accident?
The main causes are:
cable heating due to overload,
the short-circuit causing an electric arc,
an insulation fault leading to abnormal current flow between receiver and earth or between receiver and earth,
