Firefly has developed the following solutions for optimising safety in Tissue plants:

Solutions	Where	Purpose	How
WebScan™	WebScan™ is installed between the Doctor Blade and the reel-up of the mother roll.	To continuously scan the tissue web prior to reel-up to ensure that no hot particles can be transferred into the mother roll. Early stage detection of fire-related problems in or around the Yankee Hood.	By using extremely fast IR-sensors above the tissue web, WebScan^TM is able to pinpoint possible ignition sources. In the case of an indication, the contaminated mother roll should be put in quarantine.
Doctor Blade & Yankee Hood Guard	Around the Doctor Blade and Yankee dryer.	To detect and extinguish flames within seconds around the dry section of the Yankee.	Using optical flame detectors that can detect small flames at an early stage, over a large area and activate fast water mist extinguishing.
Log Saw Guard	In the Log Saw enclosure.	To detect and extinguish flames within seconds in the Log Saw enclosure.	Using optical UV/IR fire sensors that can detect small flames at an early stage, over a large area and activate fast water mist extinguishing.
Dust extraction protection	In the extraction system.	To detect and extinguish ignition sources in ducts and avoid dust filter fires and explosions.	Using extremely fast IR sensors that can detect sparks and hot particles and eliminate them before they reach the filter. Extinguish with water, isolation and CO2, or diverting the air flow.
