1. Core Regulatory Framework
ISO 1496-3 (Tank Containers)
UN Portable Tank Regulations (T-Code system)
IMDG Code (International Maritime Dangerous Goods)
ADR / RID (European road and rail transport regulations)
CSC (Convention for Safe Containers)
Supporting domestic standards may include GB/T 16563 and regulations for mobile pressure vessels.
2. Tank Design and Material Compliance
Material Compatibility
Tank materials must be compatible with the transported hazardous substances.
Common materials include 316L stainless steel, internal linings, and corrosion-resistant coatings.
Classification & Design Requirements
Tanks must comply with UN T-classification, meeting specified design pressure and vacuum requirements.
Sealing Integrity
Fully sealed конструкции verified through:
Hydrostatic testing
Leak (tightness) testing
Non-destructive testing (NDT)
3. Mandatory Safety Devices
All safety devices must be installed, functional, and within valid calibration:
Emergency shut-off valves
Safety relief valves / rupture discs
Pressure gauges
Level indicators
Anti-static grounding devices
Overfill protection systems
Manholes and discharge valves
4. Inspection Intervals (Mandatory)
Every 5 Years (Periodic Inspection):
Full inspection including hydrostatic test, leak test, NDT, and safety device verification
Every 2.5 Years (Intermediate Inspection):
Visual inspection, sealing check, and functional testing
Certification Requirements:
All inspection certificates must be valid.
Tanks with expired certification must not be used.
5. Pre-Loading Controls
Three Checks:
Tank condition is intact
Certificates are valid
Cargo documentation (MSDS/SDS) is complete
Three Verifications:
Compatibility between tank and cargo
No mixing of incompatible substances
No overfilling (≤ 95% filling ratio)
Proper display of UN number, hazard labels, and warning markings
6. In-Transit Safety Management
Compliance with IMDG / ADR requirements for stowage, segregation, speed limits, and escort (if required)
Continuous monitoring of temperature, pressure, and liquid level
Anti-static measures and collision prevention
Emergency Equipment Onboard:
Leak containment kits
Chemical protective equipment
Fire extinguishers
7. Unloading and Cleaning
Follow standardized unloading procedures to prevent splashing, vacuum conditions, and leakage
Perform professional cleaning, purging, and residue detection after unloading
Dispose of hazardous waste in compliance with regulations; cross-contamination is strictly prohibited
8. Emergency Response Essentials
Leakage:
Close emergency shut-off valves immediately
Establish a safety perimeter
Contain the leak
Handle according to SDS guidelines
Fire:
Use appropriate extinguishing methods based on the substance
Cool surrounding areas and isolate the source
Notify emergency services promptly
General Requirements:
Personnel must wear appropriate chemical protective equipment at all times
Unauthorized or unsafe operations are strictly prohibited
