Distributed Switchgear (IEE Power & Energy Series) - …

Two French scientists, Moissan and Lebeau produced the first samplesof this gas at the turn of the century during laboratory experiments involving theelectrolytic action of fluorine on sulphur in a copper tube. The gas produced, SF6,was a remarkably stable gas that would rapidly recoine if dissociated.

Fire extinguisher - Wikipedia

2019-4-20 · A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a
