halon gas effects
On the other hand, in KSA in the early 'eighties my colleague and I were subjected (inadvertently) to the effects of two 4ft x 18ins dia halon gas bottles being discharged into a computer room where we were conducting a fire detection/suppression system acceptance test. Due to a wiring problem/teflon tape error, the smoke detection-alarm condition turned into an unplanned discharge of the two halon tanks. Unlike helium gas which turns the human voice to Mickey Mouse qualities, the human voice under the effects of halon becomes like HAL9000 exaggerated and it is like being drunk. The false floor tiles lifted, floated and rippled accompanied by "Ha-Ha......Dave....why....did....you....do....that" giggle...giggle..giggle. The effects lasted for some seconds after exiting the room but, as far as I am aware, had no lasting impact (unless you talk to my wife !)
