Explosion in this Policy is deemed to mean any sudden release of energy resulting from the expansion of gases or vapour.
The bursting of a container (boiler, pipe etc.) is considered as an explosion if the walls of the container are torn open to such extent that a sudden equilibrium of the pressure inside and outside the container takes place.
If an explosion occurs inside a container in consequence of a chemical reaction, any damage to the container is indemnifiable even if the walls of the container are not torn open.
Loss or damage caused by implosion is not covered by this Policy.
Loss of or damage to combustion engine resulting from the explosion taking place within the combustion chambers or explosion of any part of electrical switches arising from gas pressure is not covered.
If explosion is also covered by more specific policy, the Insurer shall only indemnify the remaining loss from the amount which should be payable under such other policy as if this Policy does not exist.
