Cellulose insulation is not a unique substance. It is a combination of paper fibers and other materials whose physical, chemical, and biological characteristics are well known. Cellulose fibers are classified as "nuisance dust," that is, dust which while possibly irritating and unpleasant, is not a health hazard. Cellulose insulation fire retardants are also well-characterized and regarded as nonhazardous. The toxicity of boric acid, a common fire retardant in cellulose insulation, is virtually identical to that of table salt. Other cellulose insulation ingredients are equally benign.
Because of the scientific community's thorough familiarity with the materials used in manufacturing cellulose insulation, it has not been considered necessary to conduct health effects studies specifically on cellulose insulation. Cellulose producers can supply material safety data sheets for all relevant components of their products.
A 2001 health hazard evaluation report from the National Institute for Occupational Safety and Health (NIOSH) states that the highest concentration of respirable airborne fibers and particles released during cellulose insulation installation was five times lower than the federal OSHA exposure limit. NIOSH concluded that a common N95 dust mask provides adequate worker protection.
Mold has become an important indoor air quality and health issue. For various reasons associated with the manufacturing process and its moisture control properties few cases of mold contamination of cellulose insulation have been reported. Insulation that becomes wet should be inspected for mold.
