Welcome to the “Using Fire Extinguishers Effectively” video lesson meant to describe the different classes of fires and how to put them out properly using portable fire extinguishers. From this lesson, viewers will first learn about when to use portable extinguishers instead of evacuating. Then, the viewer will hear about the classes of fire, from class A to class K, and the right extinguishers to use for each of them. Plus, the learner will get an overview of the PASS technique for using portable extinguishers. That way, viewers will be able to assess and respond to fires by choosing the right extinguisher the situation calls for.
