Some combustible materials include fuel oil, paint, kerosene, paints, cesium, magnesium, aluminum powder, calcium, sawdust, plastic dust, coal, flour and powdered metal. Combustible liquids are different from flammable liquids in that flammable liquids have flash points below 100 degrees Fahrenheit and combustible liquids have flash points above 100 degrees Fahrenheit. A flash point is the lowest temperature at which a liquid releases enough vapors to start burning.Know More
Other combustible liquids include acetic acid, camphor oil, cyclohexane, varsol, methyl lactate, phenol, carbolic acid and aniline. Liquids that also have flash points above 100 degrees Fahrenheit are benzaldehyde, ethylene glycol, phenyl ether and stearic acid.
Flammable materials also undergo combustion, but OSHA does not classify them as combustible materials. Liquids such as gasoline, ethanol, turpentine, potassium sulfide, napthalene and sulfur are flammable materials that give off vapors below 100 degrees Fahrenheit.
Combustion is the chemical process of burning hydrocarbons in the presence of excess oxygen and heat to produce water and carbon dioxide. Simple hydrocarbons such as methane and ethane break down their carbon and hydrogen atoms to bond with oxygen during the exothermic reaction.
Pure hydrocarbons burn with a blue flame and have no solid remains. Impure hydrocarbons such as wood, leaves, plant materials, trash and rubber give off yellow-orange flames and grayish-black soot. Impure hydrocarbons also give off carbon monoxide as a product.Learn more about Chemistry
Tannerite is a binary compound explosive that consists of ammonium nitrate and aluminum powder. The ammonium nitrate component provides the fuel for the explosive, and the aluminum powder acts as a catalyst. The compound is stable under normal conditions, and because it ships as two components that are not independently explosive, no special permits or restrictions apply to its handling.Full Answer >
Making homemade Tannerite requires ammonium nitrate, aluminum powder, blenders, an open space with no open flames and several large containers. As of 2015, it may be difficult to find ammonium nitrate in bulk; some choose to use cold packs that include it as an ingredient.Full Answer >
Many of the materials that are used to muffle sound are made from porous substances, such as cork or foam rubber. Mineral wool is a sound-proofing material made from inorganic fibers that can be shaped to fit into areas between walls to provide a greater degree of sound reduction in a room. Thicker and denser materials tend to muffle sound better than lighter materials, and rougher surface areas will absorb more sound than smooth surfaces, which will reflect sound waves instead.Full Answer >
Underwriters Laboratories and the Occupational Safety and Health Administration are excellent resources for the listing of non-combustible materials. UL provides safety testing and certification in various sectors, while OSHA maintains well-known safety data sheets.Full Answer >
