Fire protection for the hygiene indudstry

Absorbent material and air – a potentially explosive mix

Absorbent materials, such as diapers and sanitary products, are manufactured from specially treated wood pulp in a vacuum process. This flow of wood dust trapped in an air stream can cause a fire with high energy in the event of temperature rise. Ignition sources can also ignite the product while in storage, or set fire to dust around the plant or accumulated in filters. This can result in a devastating fire, causing substantial damage and costly production downtime.

Any sparks and hot particles, produced by the mill or fan, need to be detected and extinguished to avoid igniting material in the process. Firefly’s solutions detect sparks and hot particles before they reach the filter, extinguishing the heat source with CO2 or water, or by diverting the airflow.

Acute risk of dust explosions

Dust explosions can occur whenever combustible dust spreads in the air. Material in the form of dust has a large surface area, compared to its solid state, and can become extremely volatile. A dust explosion can cause substantial damage and may also start a fire that propagates through the plant.

The ignition temperature of a layer of layer of cellulose is around 270°C. For a cloud of cellulose dust, the ignition temperature is around 480°C . Hot items below 650°C are not seen as glowing by the human eye, so these are relatively low ignition temperatures.

This risk of dust explosions is particularly acute when manufacturing baby diapers and personal sanitary products. Here, the pulp is sucked onto a polymer film by a vacuum system which operates in the same way as a dust extraction system, after first having been milled and transferred to a forming station where Super Absorbent Polymers (SAP) are added.

Overfeeding or malfunction of the mills can cause ignition, as can problems at the forming head, or fan failure. Ignition sources can ignite the product, in the worst case while in storage, or it can ignite collected dust in the dust filter.

A fire on a processing line for absorbent materials can progress with extreme speed. To prevent substantial fire damage and lengthy shutdown, the source of the ignition needs to be identified and extinguished quickly.

Firefly protects the facility by detecting sparks and hot particles before they reach the filter, using IR-radiation detection and extinguishing with CO2, isolation, water, or diverting the airflow.

Unique Fire Protection Solutions for the hygiene industry


The Quick Suppression System, which is part of our protection solution for shredders, operates with high performance flame detectors for extremely quick detection. The efficient water mist system has remarkable suppression capabilities which reduce damages on machinery.


The True IR Spark detectors enable Precision Detection of ALL types of ignition sources such as hot black particles, glowing embers and sparks. Systems are also equipped with Multi-Channel flame detectors using advanced algorithms for Precision Detection of flames with high immunity to false positives.


The Water Mist System with fire-tested and verified extinguishing capabilities utilizes very small amounts of water resulting in less impact on machinery, minimized production loss and down time.


Dust extraction systems are vital to take care of dust generated in dry bulk handling processes. The risk in these units is considered very high due to the high concentration of dust. Firefly’s FM-approved Spark Detection and Extinguishing System will efficiently prevent ignition sources from entering the risk zones.

Keeping industry leaders safe


Project Manager


“The installation of the Firefly systems has brought safety to the operators. Before, we had to be very observant and we knew that our reaction was crucial for the handling of incidents. Now we can rely on the Firefly Fire Protection System.”


Corporate manager

Acme corp

“Firefly has been on our side since day one, we have worked with their team during the project definition to get the best ratio between risk management and CAPEX optimization. Firefly keeps our people safe while we concentrate on improving our performance standards in the alternative fuel industry.”


Project Engineer


“With the Firefly System an early detection of hot particles leads to immediate extinguishing and prevents the build up of a fire. Since the system was installed, Cérélia has had numerous detections but no fires.”
