Távoltartási

Távoltartási is a term used in electrical safety to denote the process and measures aimed at removing electrical energy from equipment or installations and maintaining isolation to prevent energization during maintenance, inspection, repair, or installation. The goal is to reduce the risk of electric shock, arc flash, and unintended startup.

In practice, távoltartási is closely linked to lockout and tagging procedures. A távoltartási engedély or similar documentation is often required, specifying the equipment, energy sources, and work to be performed. The process typically includes switching off power at the control point, isolating energy sources, applying locking devices and warning tags, and clearly labeling the area to prevent unauthorized re-energization.

Verification is a key part of távoltartási. After isolation, absence of voltage must be confirmed with appropriate test instruments, and any stored or residual energy (such as in capacitors or springs) must be discharged or rendered safe. The area should be secured, tools collected, and only authorized personnel should re-energize the system once work is completed and all safety checks are satisfied.

Scope and considerations for távoltartási cover electrical circuits, machinery, and installations. Procedures account for multiple energy sources, potential stored energy, and the need for effective communication, competency, and supervision. Regular training and refreshers are common to maintain awareness of risks and proper execution.

Regulatory context varies by country but generally follows electrical safety standards and internal organizational policies. Távoltartási practices are part of broader safety programs that aim to prevent accidents and ensure a controlled, verifiable work environment.
