Where can you find formaldehyde in wood products?
Where Is Formaldehyde Found? Formaldehyde is found in: Resins used in the manufacture of composite wood products (i.e., hardwood plywood, particleboard and medium-density fiberboard); Building materials and insulation;
What are the levels of formaldehyde in the air?
According to a 1997 report by the U.S. Consumer Product Safety Commission, formaldehyde is normally present in both indoor and outdoor air at low levels, usually less than 0.03 parts of formaldehyde per million parts of air (ppm). Materials containing formaldehyde can release formaldehyde gas or vapor into the air.
What’s the revised IDLH for formaldehyde for humans?

Which is the most stable cyclic trimer of formaldehyde?
Monomeric formaldehyde (subject of this article). Trioxane is a stable cyclic trimer of formaldehyde. Paraformaldehyde is a common form of formaldehyde for industrial applications. Methanediol, the predominant species in dilute aqueous solutions of formaldehyde.
How many ppm of formaldehyde is safe for humans?
Because Patty [1963] also reported that “it has been estimated that exposure for 5 to 10 minutes to 50 to 100 ppm might cause serious injury to the lower respiratory passages in man [Kodak 1936-1960],” 30 ppm seems reasonable as the IDLH. Other animal data: RD 50 (mouse), 3.13 ppm [Alarie 1981].
What is the use of formaldehyde in solution?
Formaldehyde is a highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic.
