Prior notification must be provided to the technical safety authority for repairs and alterations of industrial gas cylinders.

Kulcsszavak: gas cylinder, cylinder valve, repair, alteration, technical safety

Self-employed or company engaged in gas cylinder repairs or modifications

The approval of the technical safety authority is required to change the codes and colour markings stamped on industrial gas cylinders. Only the maintenance organisation may perform repairs and alterations on industrial gas cylinders and their accessories, and only as specified in the repair or alteration documentation. The maintenance organisation performing the repairs must notify the Budapest or county government office acting as the technical safety authority of the planned activities.

After receiving the notification, the authority will examine the notification and its annexes. If the notification is correct, the notifying body will be entitled to carry out the activity.

The designated body shall be requested to perform a technical safety inspection after all gas cylinder repairs and alterations. The inspection shall determine whether the cylinder complies with the repair or alteration technical documentation, the requirements specified in the official decision, and the provisions of the relevant legislation.

If the notification is unsuitable and the authority determines, during the course of the inspection, that unlicensed activities are being conducted, the notifying body will be prohibited from pursuing the activity in question.

If, during the course of the procedure, the technical safety authority identifies any error or deficiency in connection with the relevant safety and reliability requirements or that the equipment may pose a threat to health, safety, property or the environment, or its use may result in a situation that causes such damage, the authority may:

  1. order that the deficiency be rectified or the error be corrected, setting a time limit that takes into account the applicable conditions, and
  2. in case of a deficiency that results in a direct threat, immediately and permanently prohibit its use or, if the threat can be averted, prohibit use until such time as it can be averted.

 Since notification is provided in advance, there are no time limits in this procedure.

The following documents must be attached to the notification:

  1. the dimensioned technical drawings prior to the gas cylinder repair or alteration,
  2. the specifications regarding the mechanical properties and chemical composition of the gas cylinder material, and
  3. a description of the repair or alteration method and the inspection method.
