Rhodia Alarm Test, Langley

Tuesday, August 14th, 2012

Rhodia, a division of Solvay,  is a large chemical manufacturing plant in the small community of Langley, West Midlands.  Every year they test the off-site alarm, intended to warn local residents of potential danger resulting from problems at the plant such as chlorine gas leaks.

On 9th August at 12.00pm I managed to make two recordings of the alarm which sounds very similar to an air raid siren. The first was from just outside the factory gate, made with two small omnis hung out of my car window.

The second was made with a stereo microphone from Langley park, about half a mile away.
