what is the difference between UPVC AND CPVC AND PVC pies, anyone can tell appropriate use of each pipes?
It's for different fire types. I think A is regular, B is electric, and C is chemical.
It means they were using a tarot of the spirit deck.
I have the same problem, but its because i have a smoke/heat detector. If the air in the bathroom is too warm after the shower it will trigger the alarm. After I shower, I open and close the door a few times to let the warm air out of the bathroom in short bursts so the alarm doesn't go off anymore. A good way to resolve would be to turn on the fan in the bathroom if you have one. Unfortunatley I live in an older home and don't have one.
I co-own an extinguisher service company so here is your answer. The number is called a UL rating. ALL extinguishers have some type of UL rating classification. For instance, an extinguisher rated 2A 10BC is UL's way of telling you that the extinguisher is capable of extinguishing 2 cubic feet of class A material, 10 square feet of burning liquid, AND the C simply means that the extinguishing agent does not conduct electricity. I hope this helps.
