As you can see from the graphic above, sources of Formaldehyde Gas are common throughout most homes and can be steadily off-gased from lit cigarettes, storage cabinets made of particle board, subflooring, carpeting, wallboard, electronics, furniture, ceiling and flooring materials, door casings, insulation, household chemical products, and open stoves or heaters - just to name a few man-made sources inside. Indoor storage areas should be equipped with automatic sprinklers. Washington, DC: Association of American Railroads, Bureau of Explosives, 1994., p. use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures. However, not all incinerators are suitable for this purpose. is probably the gas-fired type, in which a first-stage combustion with a less than stoichiometric air:fuel ratio is followed by a second stage with excess air. to absorb soln onto suitable combustible material, such as sawdust.
Formaldehyde Gas is one of the most common among thousands of known volatile organic compounds (VOCs) which often contribute to indoor air pollution in homes and workplaces. Storage tanks should be adequately grounded to discharge static electricity and to reduce other electrical hazard. Toxic and Hazardous Industrial Chemicals Safety Manual. Stop or control the leak, if this can be done without undue risk. Quincy, MA: National Fire Protection Association, 1997., p. 707]**PEER REVIEWED**Formaldehyde is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration.

So reducing Formaldehyde gas hazards is often not as simple as buying eco-friendly furnishings, replacing carpeting with hardwood flooring, or creating a cigarette smoke-free environment indoors. A general index of technical names has also been compiled. The latter may be stored at room temp without precipitation of solid formaldehyde polymers because it contains 5-10% of methyl alcohol. Materials of construction preferred for storage vessels are 304, 316, and 347-type stainless steels or lined carbon steels. Treatment and Disposal Methods for Waste Chemicals (IRPTC File). published have not been tested on all kinds of carcinogen-containing waste.
