CATU Lockout Tagout Padlocks

Irrespective of whether servicing or work involves an item of electrical installation or work equipment, a lockout must be done to ensure the safety of the workers.

Depending on the environments, default lockout accidents are caused by the:

  • Continued presence of live conductor parts for electrical installations
  • Presence of pressurised fluids (hydraulic circuits)
  • Presence of unstable mechanical systems

What Does Locking Mean?

The purpose of locking is to separate cut off or neutralisation parts with a suitable, and sufficiently protected system to prevent any operation by unauthorised persons (switching on power for an electrical installation). Locking is generally accompanied by signs.

For the electrical domain, setting up and removing the lockout are described in French and European standards (EN50110-1).

More generally, the safety recommendations are included in Directive CE7: 2009/104/EC on the minimum health and safety recommendations for using work equipment.
