I'm doing homework for my class and little problem.
My book that I ordered for a 2nd day air mail delivery is on its... well, 4th going on 5th day with no result and its due tomorrow.
I was wondering if anyone here can possibly help with a couple of questions:
What are the threee established criteria that must be met for a Class K extinguisher
What are the other criteria items that extinguishers must meet in addition to the UL Rating?
What anti-freeze agents are used in portable fire extinguishers?
