Fire in chemical plant (Seveso-classified)The fire developed at the top of the flare stack of a during a violent thunderstorm.The flare stack is used to discharge hydrogen produced by the restarting of chlorine electrolysis cells. The fire was ignited despite steam and nitrogen had specifically were injected to prevent it from occurring. The sites firefighters cooled the flare stack while the technicians turned off the electrolysis cells to cut off the hydrogen feeding the flames.

As the airship approached the docking mast, it performed a sharp turn to face into the wind, which was shifting. The engines were run at full speed astern for about a minute to slow the airship. Dust came from the lines as they dropped to the ground, but the lines wetted in the light rain. Only the port line had been attached to a ground winch used for drawing the airship down to ground level for disembarking passengers and cargo. The starboard line was being handled by ground crew at the time of the fire. The nose cable had been lowered about 50 ft.
