Why the electrical empowered?
Electrical accidents come from:
• Equipment failure (10%)
• Lack of training (14%)
• Failure to respect work steps, inaccurate procedures (15%)
• Ignorance of risks (30%)
• Inappropriate or dangerous procedure (31%)
The purpose of this authorization is to safeguard people and property, and the competence of those involved in electrical safety.
For who ?
Electrical accreditation is established to ensure the safety of people carrying out electrical or non-electrical operations against all electrical hazards when they use or work on electrical installations, off or on, in the environment or in the vicinity. of these.
The electrical authorization describes the safety, prevention and protection rules for carrying out in complete safety:
• Electrical operations on electrical installations or equipment
• Non-electrical operations in the environment of electrical installations or equipment.
Why NF C 18-510?
A new approach
- Drafting of a standard of general electrical safety instructions
- Based on the concept of risk analysis (according to the spirit of the 2004 law)
- Considers that prevention is the result of a chain of action from the manager to the performer
- Gives each actor the tools so that he can carry out the electrical risk analysis at his level of responsibility
- Takes into account the evolution of work organization
Poorly identified pipe
Having noticed a fault on the electric supply riser of a building, an electrician intervened on the electric cables in the presence of a representative of the energy distributor.
After disconnecting the electric cables, the electrician touched them with his bare hands. He was electrocuted. The cable lockout was not carried out, nor the check for the absence of voltage.
A plumber intervened to repair a leak in the underground water supply pipe of a single-family house. Wanting to cut it, he cut the power supply cable, which has the same exterior appearance as the water pipe buried 10 cm below in the same alignment. No scabbard or wire mesh was in place. The victim died
Failure to follow procedures
By wanting to move a halogen projector loaned by the owner of the premises and plugged into a socket newly installed by an electrician, a worker was electrified. A witness immediately removed the plug from the wall outlet and the victim collapsed.
Analysis of the accident revealed that the phase of the halogen projector was connected directly to the earth of the device and that the protection of the socket was provided by a differential circuit breaker of 500 mA and not of 30 mA and which, moreover, did not work.
High voltage line
An experienced driver had to deliver concrete for a pavilion patio using a router truck fitted with a carpet so that the concrete could be discharged from a distance.
A 20,000 V high voltage line passed above the pavilion. The driver unfolded the rug from the spinning top and then led it to the terrace, passing over the house. Wanting to center it above the terrace, he raised it, thus establishing electric arc ignition.
The driver died because, at the time of the carpet / power line impact, he was holding the metal control levers on the carpet.
