In a holiday camp, lightning struck the lightning rod and caused an electric arc between the lightning rod and the underground gas supply pipes feeding the kitchens from a propane cistern, resulting in ignition of the gas. One individual onsite reacted quickly and put out the fire using an extinguisher. However, the faulty trigger-regulator on the cistern did not shut off the supply line despite the pressure drop due to the leak, and the gas continued to spew. The manual valve on the cistern had seized and could only be operated later on by a fire-fighter on the scene. 124 children and camp counsellors had to be evacuated during the emergency intervention. The regulator was changed the very same night by the gas distribution company, which owned the cistern. The underground pipe was made of copper and ran at a distance of just 20 cm from the lightning rod (while good engineering practice dictates a distance of 1 m). The building was scheduled for demolition in August of 1994 and the entire gas installation was due to be replaced.
