This technical regulation classifies LPG containers into three types: above-ground containers, underground containers, and mounded containers (installed on the ground and covered with sand or soil).

 

Technical requirements:

The requirements set by this regulation are classified into 2 types: General requirements and Specific requirements.

  1. General requirements
  • LPG Containers must be designed, manufactured, tested and labeled in accordance with this technical regulation and related laws and regulations.
  • Equipment and accessories used for handling LPG containers must be dedicated to LPG containers.
  • Any LPG containers that are deformed, over-polished or corroded must not be used.
  • Repairs and refurbishments of LPG containers must be carried out in accordance with applicable standards set by the relevant manufactures.
  • Any outdoor or indoor unit such as those of an air conditioner must not be installed in the container.
  • Inspection of LPG containers may be carried out pursuant to technical standards that are requested by user or manufacturer facilities provided that the standards ensure a higher level of safety compared to the requirements set forth in this technical regulation.

 

  1. Specific requirements

No.

Item

7 Requirements on maintenance Maintenance personnel, procedures, implementation of regular maintenance (at least every 5 years), documentation of maintenance, etc.
8 Regulations on inspections and tests Tests on pressure and containment performance, thickness measurement, magnetic measurement, etc.
9 Regulations on inspections Deadline and format of regular inspections, abnormality inspections, risk-based inspection (RBI), inspection procedures and documents, etc.

 

The list of Tables included in this technical regulation is as follows.

Table 1 Minimum outflow of safety valves for underground containers and mounded containers

Table 2 Safe distance between LPG containers and hydrogen containers or oxygen containers

Table 3 Minimum safe distance between LPG containers and construction sites or buildings or offices and that between LPG containers
