What is a Class C fire?
Fire class is a term used to denote the type of fire in relation to the combustion material which has ignited. A Class C fire is described as a fire involving electrical equipment, machinery, electrical cables, appliances etc.
All Firexo Fire Class ratings have been achieved through the EN fire tests.
A Class C fire in the U.S. is considered a Class E fire in Europe. For this reason, detailed below is the EN fire test explanation of a Class E fire:
When testing an extinguisher against a class E fire the test is to ensure that when discharged, electricity does not flow up through the extinguisher and cause harm to the user. If an extinguisher achieves a class E rating, it means the product can put out electrical-based fires and material if they were to catch on fire.
The test is performed in an electric chamber purposely built for the test for accuracy and safety reasons.
Within the test 35kV (35,000 volts) are pulsated through a large steel plate, whilst an extinguisher is discharged aimed directly at the plate from one meter away. If the current that runs back through the extinguisher is below the required amount to be considered safe, the extinguisher passes the test.
The extinguisher must pass two fire tests to be deemed for that class 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.
