Air Ministry Official Notices

Abstract

The attention of all concerned is drawn to the need for guarding against the effects of poisonous fumes when using chemical fire extinguishers of the types usually carried in civil aeroplanes. One of the dangers to be guarded against is that at low concentrations the fumes may have no smell, or such smell as there is may not be unpleasant, and may not suggest that breathing the air is in any way dangerous. Exposure for half an hour or so to such fumes may nevertheless produce subsequent ill effects, though none may be noticed until some hours after the exposure has ceased.
