Calculating safety distances by o Programs like Phast DNV, Effects, Safeti to give an indication of the effects on
thermic and concentration (Quick & dirty methods) o More specific with Computational Fluid Dynamics o Literature study o Depends on:
A. Source type (liquid, gas, vapour, composition) B. Atmospheric conditions (wind, temperature, humidity, turbulence) C. Ground effects (surface, heat flux, obstacle)

Evaporating rate in water 15 m3/min/m2
Evaporating rate on land (depends on type of soil) 3 m3/min/m2 In steady state 0,3 m3/min/m2

Possible impact of an accident with LNG? o Type release -> Atm. Pressure (instantaneous vs continuous) pool fire, vapour
cloud explosion, flash fire, cryogenic effects o -> 4 Bar(g) (instantaneous vs continuous) BLEVE, fire ball, flash fire, jet fool
and the rest as mentioned above Prohibited areas for the storage and bunkering of LNG, near schools and
hospitals and other (partly) dependent people

Safety standards for staff/crews (distances) Distances o Loss of control in gas (LEL Distance: 250*D) o Loss of control in liquid (LEL Distance: 500*D) o Flare Distance in liquid: 250*D o Flare Distance in gas: 500*D o Evacuation and preventing ignition sources 2*Flare Distance or 2*LEL Distance

Disaster Management
Emergency response - fire
Emergency response - rescue
Disruption business as usual
Mutual Aid – LNG (e.g. TUI)
Steel structures failing
Major pool or gas release
Roll over truck
Transfer content damage teuck
Flare
Leakage in gas fase
Maintenance pipework valves
Prevent BOG
Disturbance/error in LNG instruments Operator LNG system
LNG intervention
Fire Medical Police
Ministerium
