what are the materials used in the foam used for fire safety?

If you mean foam as a suppression agent, they are usually protien or soap based.  When mixed with water they create the "foam" that can used to blanket a fire, particularly when flammable liquids are involved and water alone would simply spread the fire becuase most flammable liquids float on water.

Pretty much any material that H2O2 can't oxidize and that the water it's dissolved in can't corrode. Glass should be safe, as well as the plastic or glass container it came in. Things to avoid: "Heat, reducing agents, organic materials, dirt, alkalis, rust, and many metals. Spontaneous combustion may occur on standing in contact with readily flammable materials." (Ref.) \nThe higher concentration form (30%) is hazardous and unstable, requiring extreme care in use.

It would be an insulator because it creates a generally air filled barrier between two objects. I do not believe it's flame retardant. Polyethylene melts easily. Polypropylene has a higher melting point and is usually used in those disposable food storage containers.

hi, \n\nacetone will do the job nicely.\n\nbe careful, though, it essentially is making napalm.\n\nhere is a list of the effects of variuos solvents, though i think it's on bulk polyurethane, not the foam:\nhttp://www.rimnetics.com/rimsolventsheet.htm\n\nanything there that says breaking, collapse or degradation would probably eat the foam up.\n\ncheers!

white. \nBuring magnesium is white hot, and believe me you wouldn't want to be near it when it does go up.  It is hot enough to break down the molecular structure of water into oxygen and hydrogen and then ignight the following gases.  Firefighters usually have to find other means to fight magnesium fires other than using water.

Try looking at a substances MSDS.  That is Material Data Safety Sheet.  If it is a pure substance that will be helpful. Just put the name of the substance and MSDS into yahoo and you'll find a sheet

Surfactants are used to prevent the surface tension forming the bubbles.  However, carefull experimentation must be done to make sure they do not have a negative effect on the strength of the concrete.

Use Leather- Like a welding glove! \nIf you are working with really high temps get a "fire blanket" like from a sporting goods store. (I believe it has asbestos in it??)

with a lint free cloth and an anti-static foam(alcohol based not water).

Any non combustible material is fire resistant, take your choice it depends what you want to use it for. (Don't try to put a chip pan fire out with a house brick)LOL

depends on the fragile item.  Foam 'peanuts' work great for almost anything.  Newspaper, balled-up newspaper for heavier items, bubble-wrap, sponge

plastic, but it doesn't breathe, so for a person or something, wool is good.\n\nAs for insulating something that is not a person, combinations work well, and so does aluminum foil.

Celestine is sometimes used to produce a red color in fireworks. Charcoal (carbon) is also used in pyrotechnics. Charcoal from soft woods, such as grape vine or willow, is good for fast-burning compositions like black powder, whereas charcoal from hard woods like pine are used to create long-lasting spark effects. \n\nIn any laboratory setting proper personal protection equipment should be employed. I recommend using safety glasses, a laboratory coat, full length pants and latex/polyethylene gloves. You shouldn't wear open toed shoes and loose articles of clothing that could snag. In cases were an explosion is possible, proper shielding is required. A fume hood is also required if hazardous fumes are expected.\nAlso, if you are resorting to using an online forum to recieve answers to potentially dangerous reactions, you obviously do not know what you are doing and should gently place down your little pyrotechnics and slowly back away.

High tensile strength steel...however there are other non-metals that are actually stronger...carbon fiber materials being one possibility.

i think this should help........\n\nhttp://chemistry.about.com/od/chemistryhowtoguide/ht/foamfight.htm\n       or even this\nhttp://chemistry.about.com/cs/howtos/ht/buildavolcano.htm

because the foam is white
