Hazardous Chemical AccidentKungsbacka Sweden,
march 2005

A trainset with twelve cars loaded with 700 tons
of chlorine derailed south of Gothenburg, Sweden,
on the 28th of February 2005. The engine and
three of the cars were of the tracks. The other
nine cars were emptied and removed. After a
week, the engine and the three derailed cars,
still loaded with chlorine, remained.
3
The remaining cars were damaged and stuck
together making them difficult to empty.
Cutting the chlorine tanks from the carriages
would make for a less risky removal. However the
chlorine could not be heated so the Gothenburg
Rescue Agency (Räddningstjänsten Storgöteborg)
opted for a cold cutting method using water jet
technology.

In recognition of their expertise in water jet
cutting Cold Cut System AB was asked to assist
with the accident.
