What is a Class A fire?
Fire class is a term used to denote the type of fire in relation to the combustion material which have ignited, a Class A Fire is described as combustible materials consisting of Paper, wood, fabric, textiles, plastics etc.
All Firexo Fire Class ratings have been achieved through the EN fire tests.
Class A fire rating explained:
Within the class ‘A’ test, a wooden crib is constructed by stacking wooden beams into a cross-hatch pattern on top of each other – somewhat like Jenga but with 6 centimeter gaps in-between each wooden beam, allowing the fire to ignite and spread. The fire is lit from underneath using fuel trays with a quantity of heptane inside, and allowed to burn for 2 minutes; the fuel trays are then removed. The fire is allowed to burn for a further 6 minutes making the burn time 8 minutes in total.
At this point the designated fire fighter is sent into the fire with a single extinguisher to extinguish the fire at their discretion. In order to pass the test, no flames can remain present throughout the entire structure once fully extinguished, and as further proof of no reignition, an additional 3 minutes is timed to ensure no naked flames reoccur for absolute confirmation of no reignition.
The certification requirement states that the extinguisher must pass at least two out of three tests in order for the extinguisher to be deemed successful for a class ‘A’ rating.
In the U.S. the fire tests, as detailed in UL7111, are very similar for all classes of fire but there are subtle differences such as the height of the Class A crib, shape of the Class B tray, or the number of liters required for Class K. Firexo is currently undertaking the UL Certification and Approval process and hopes to achieve UL Listing as early as Q1 2021. Please watch this space because we will be updating it to the show the UL fire tests as they are achieved, demonstrating why Firexo is the most effective fire fighting media on the market today.
