Viet Nam Updates LPG Gas Containers Safety Standards

Viet Nam has enhanced safety standards for LPG gas containers through technical regulation amendments, specifically targeting steel and composite cylinders.

Compliance Analysis: Enhanced Safety Standards for LPG Gas Containers in Viet Nam

Viet Nam has strengthened safety standards for LPG gas containers, specifically steel and composite cylinders, through recent amendments to national technical regulations.

Below is a structured breakdown of the compliance requirements.

1. Scope of Regulations

The amendments target two distinct categories of LPG containers:

• Composite LPG cylinders: Covered under QCVN 16:2022/BCT (as amended by Amendment 01:2026)¹.

   • All measuring devices used in testing must be calibrated, verified, or tested in accordance with Viet Nam’s metrology laws.

1. Storage and Warehouse Safety¹:
   • Segregation: Composite LPG cylinders must not be stored with other types of gas cylinders.
   • Ventilation: Warehouses must have at least two exit doors (opening outward) and natural ventilation.
   • Leak Detection: Mandatory LPG leak detection and alarm systems.
   • Lighting: Only explosion-proof lighting permitted.
   • Fire Safety:
   • Fire extinguishing water supply must comply with regulations.
   • Signage: "No Open Flames," "No Smoking," "Authorized Personnel Only," and fire safety instructions must be posted at visible locations.
   • Structural Requirements:
   • Walls, partitions, and roofs must be fire-resistant.
   • Ventilation openings (total area ≥ 2.5% of wall area) must be installed on walls and roofs, away from heat/electrical sources.
   • Drainage: No pipes or water drainage channels allowed on the warehouse floor.

1. Repair Restrictions¹:
   • Repairs altering the cylinder’s original design or ownership markings are prohibited.

B. Steel LPG Cylinders and Vessels (QCVN 02:2020/BCT, as amended)

1. Storage and Warehouse Safety²:
   • Segregation: Steel LPG cylinders must not be stored with other gas cylinders.
   • Ventilation: Warehouses must be well-ventilated, with two exit doors (opening outward).
   • Leak Detection: Mandatory LPG leak detection and alarm systems.
   • Lightning Protection: Lightning protection systems required.
   • Structural Requirements:
   • Floor: Must be non-slip, fire-resistant, and elevated above surrounding ground level.
   • Drainage: No pipes or water drainage channels allowed on the warehouse floor.
   • Fencing: Warehouse perimeter must be ≥1.8m high, sturdy, and not obstruct ventilation.
   • Access: Roads must accommodate fire trucks and transport vehicles.
   • Signage: Same as composite cylinders (fire safety, no smoking, etc.).

1. Repealed Provisions²:
   • Section 12 (technical requirements) and Point 10.1.4 (storage specifics) of QCVN 02:2020/BCT were abolished.

3. Conformity Assessment and Compliance

A. Composite LPG Cylinders

1. Conformity Certification¹:
   • Mandatory pre-use certification: Composite cylinders must undergo conformity assessment before use.
   • Assessment Methods:
   • Method 5: Testing of representative samples + evaluation of production processes or management systems.
   • Method 7: Batch testing of products.
   • Certification Bodies: Must be accredited under Viet Nam law.
   • Self-Assessment: Permitted if based on testing by accredited or designated laboratories.

1. Surveillance Frequency¹:
   • For Method 5 certification, surveillance testing must occur:
   • First surveillance: Within 12 months of certification issuance.
   • Subsequent surveillances: Every 24 months thereafter.

1. Marking Requirements:
   • Conformity Mark: Must comply with Article 2 of Circular 14/2026/TT-BKHCN¹.

B. Steel LPG Cylinders and Vessels

1. Conformity Certification²:
   • Mandatory pre-operation certification: Steel vessels must be declared compliant with Part II of QCVN 02:2020/BCT before use.
   • Assessment Methods:
   • Method 5: Testing of representative samples + production process/system evaluation.
   • Method 8: Full testing or inspection of all products.
   • Certification Bodies: Must be accredited under Viet Nam law.
   • Self-Assessment: Permitted if based on testing by accredited or designated laboratories.

1. Registration:
   • Manufacturers/importers must register conformity declarations under Article 37 of Decree 22/2026/NĐ-CP¹.

4. Enforcement and Responsibilities

A. Regulatory Authorities

• Ministry of Industry and Trade (MOIT):
  • Issues and amends regulations (via Circulars)^{2, 1}.
  • Oversees Department of Industrial Safety and Environment (for technical standards) and Legal Affairs Department (for compliance).
• Provincial Departments of Industry and Trade (DOIT):
  • Guidance and enforcement of regulations at the local level^{2, 1}.

B. Obligations of Businesses

1. Manufacturers/Importers¹:
   • Must ensure products comply with Law on Product and Goods Quality.
   • Must register conformity declarations for steel cylinders under Decree 22/2026/NĐ-CP.
2. Storage Facilities:
   • Must adhere to warehouse safety requirements (ventilation, fire safety, structural integrity).
3. Repair Facilities:
   • Prohibited from altering cylinders’ ownership markings or technical specifications¹.

5. Regulation Analysis Table

Summary Answer

Viet Nam’s enhanced safety standards for LPG containers are governed by Amendment 01:2026 QCVN 16:2022/BCT (composite cylinders) and Amendment 01:2026 QCVN 02:2020/BCT (steel vessels). Key requirements include mandatory pre-use conformity certification (via Methods 5, 7, or 8)^{2, 1}, warehouse safety standards (ventilation, fire resistance, leak detection)^{2, 1}, and prohibitions on unauthorized modifications¹. Businesses must comply with Decree 22/2026/NĐ-CP for registration¹, while provincial DOITs enforce local adherence^{2, 1}. The regulations emphasize preventive measures (e.g., explosion-proof lighting, segregation of cylinders) and traceability (e.g., unalterable ownership markings).
