Your question wasn't really clear but I'm assuming you mean how do you test a dry chemical fire extinguisher at home. Normally these types of extinguishers are tested at home by simply turning them upside down and listening to them to make sure the dry powder hasn't started to cake in the bottom. If you hear the sound and the gauge on the top of the bottle shows in the "green" the extinguisher is fine. Don't try to test them by pulling the trigger and seeing if they shoot, there's not a heck of a lot of powder in there to play around with.
Most fire extinguishers found in homes are single-use types, meaning that they cannot be recharged after being used. They should be replaced according to the manufacturer's recommendations. Extinguishers should be checked annually (monthly in schools and businesses). Depending upon the type of extinguisher it will also need a test every 5 or 12 years to make sure the tank is still strong enough for the internal pressure, called a "hydrostatic test".
I would imagine some sort of test involving safety equipment such as life boats, jackets, fire extinguishers and similar- and the Coast Guard has the right of inspection.
Yes, we have conducted a test for iron in the water.
Which test and when?
A pH test can be conducted to determine the acidity or alkalinity of a substance.
A gallium scan of the body is a nuclear medicine test that is conducted using a camera that detects gallium, a form of radionuclide, or radioactive chemical substance.
No, I have not conducted a protein powder test to determine its quality and effectiveness.
A ping is sent out from the testing center to the computer to identify the best server to use. Then a test of the downloading from the test facility and an upload to the test facility are conducted to test the computers speed.
No, the airport has never conducted a hand swab test on me to check for drugs.
There is no sure fire way to test paint for lead via home based chemical compounds. The only way to test for lead is to buy a lead paint test kit.
Well if your using a big water/foam (usually silver) extinguisher they last about 1 minute More Or Less. A co2 extinguisher (normal size) about... 11 seconds Other ones usually 10 to 20 seconds.
