Some acronyms that I learned about in one of my OSHA 10 classes regarding fire classifications can be helpful in making sure you have the correct type fire extinguisher in an emergency A= Ashes. B = Barrels. C = Current. D= Dynamite. K = Kitchen. It's worth noting that an extinguisher suitable for class C fires will always be a multi-class, such as A-B-C, B-C, or A-C, because the C rating merely indicates the extinguishing agent doesn't conduct electricity back to the operator, in fact if the current is shut off, then the fire can be treated as a class A or B depending on what's burning, but since we have no way of knowing if there still live current involved during the first critical moments of a fire emergency, we must always use a C rated extinguisher that is also suitable for the fuel involved when attempting to fight a fire on or near computers, motors, electrical panels and the like. It's these reasons that the A-B-C multipurpose dry chemical type is by far the most common extinguisher found businesses and homes across America, and supplemented by a class D or K extinguisher in settings where such hazards exist.

I'm currently studying NFPA10 for a job. The book that the boss gave me is 2019, not the 2022, edition. Is it so different?
My boss gave me a book from 2017
Awesome video!
