LNG and security

Explosiveness

LNG is not explosive

LNG is not flammable

Demonstration of safety measures and equipment.

When heating LNG fumes above -160F (-106.7C):

• It is lighter than air.
• It rises and disperses rather than gathers near the ground.
• Flammable at a concentration of 5-15% with oxygen.
• Explosive if flammable gas concentrations occur indoors.

 

Tank construction: safety

In particular, the design must comply with the regulations, in particular as regards safety in the following sense:

• Vapor dispersion.
• Existence of thermally excluded zones according to standards.
• Ensuring the correct separation of persons and any fire zone.

LNG and security

Ensuring the correct separation of persons and any fire zone. There has been only a few accidents in the LNG sector.

Example:

• Cleveland LNG storage facility in 1944 (info).
• Skikda liquefaction plant (Algeria) in 2004.

Security aspects:

• Management
• Handling equipment
• Equipment operation
• • LNG leak assessment
