An urgent safety notice was issued by the Survivair Company on June 16, 2006 concerning their CBRN respirator facepieces. The problem stems from the over tightening of the Air Klic into the facepiece which causes it to crack at the molding knit line. The crack has been shown to decrease the rated air time of the cylinder by over one minute in some cases.

Survivair recommends that all users of the series 2420XX series facepieces inspect to determine if there is a crack in the nozzle. If cracks are found they recommend taking the facepieces out of service and contacting them for replacement Air Kilcs and nozzles.
