I asked this question, but I have some more information. Its a sheet of rubber. That you can cut out what size or shape you need and than place it where you want to. Like under something that is shaking.Its not electric tape. Its maybe 1/8 of an inch thick. Or close to there. Its like a seal. Or it is a seal. You use it to seal things. I know this question is not clear at all, but please throw anything that I might find useful. Maybe some kinds of tapes and other things.
Yes, It COULD be done, but it would then open-up the entire building to illegal entries.
Laser light is just part of normal light. A single frequency of the visible spectrum. So with it being in the visible spectrum, we see it as whatever colour is produced by the frequency of light stimulated by the laser generator. Different frequencies give different colours.
Think of it like this. A-Ash or paper,bedding material..etc B-Barrel or oil and petroleum C-Current or electrical That just leaves one more D-Combustible Metals.these are found on certain types of steel boats such as tugboats. Old fire extinguishers used to have just A,B,C,and D on them but they tried to make them idiot proof by putting pictures of each class of fire on them such as a flaming outlet and plug for Class C fires and so on. But you should also have the classes under the picture. Hope this helps
They'll usually indicate the class of fire that the extinguisher is designed for: Class A - ordinary flammables (paper, wood, etc,), Class B - petroleum-fueled fires, and Class C - electrical fires.
It will indicate what type of fire the extinguisher is designed for. electrical, liquid fuel, solid fuel or all of the aboveI forget which symbol goes with which fuel.
