It's OKAY to dry fire a C02 pistol but do not dry fire a spring or pump pistol or rifle. When the piston in a spring pistol compresses the air inside the chamber to fire the pellet is actually slows down as it decompresses the spring piston just before it fires the pellet out of the chamber. This slowing down Keeps the piston from slamming against the end of the chamber and ruining it. When there is no pellet in the chamber the piston has no resistance and slams against the end of the chamber. This will eventually destroy the piston and the air chamber.
Depends on what the maker says.
If it's a C02 powered system then yes you can dry fire it. If it's a spring powered system the NO do not dry fire it. It will damage the system.
yes it will catch fire if air is too hot.
For most pistols, it can damage the firing pin. This is not true for all pistols. Recommend buying a "cap" cartridge that is a dummy round that can be fed and dry-fired in an automatic pistol without causing damage.
Yes
It suffoctaes the fire by depriving the fire of air which it needs to burn.
yes, if the wood is dry and the air is hot enough
It covers the burning material, pushing out air - which the fire needs to 'breathe'. Essentially - it suffocates the fire.
You don't do it any good.
Wash, dry clean, or air out.
Being a licensed master plumber and a licensed master fire suppression piping contractor all I can say if a dry system has no air pressure YOU HAVE MAJOR problems and need to have the air pressure replenished
Fire needs three things to burn: fuel, oxygen, and heat. Take away one or more of those three things in sufficient quantities, and the fire can no longer burn..A dry chemical fire extinguisher sprays a noncombustible, air resistant layer of foam designed to cover the fire's fuel source. When the fuel source (wood, oil, cloth, etc.) is completely and properly smothered, the expelled dry chemical foam isolates the fuel from the surrounding air, and thereby starves the fire of the oxygen it needs to burn.
