Toxicity Study of Cellulose Insulation: Atmospheric Characterization, Particle Size, Chemical Composition, and Workplace Exposure Assessment
Daniel L. Morgan (au)
Cellulose insulation (CI) is produced mainly from recycled newspapers, which are shredded & treated with fire-retardant chemicals. The materials are installed by blowing, which creates a potential hazard to workers. This study examined the physical & chemical properties of CI aerosols & surveyed several workplace exposure conditions to determine if such a hazard exists. Of the cellulose insulation particles examined, less than 0.1% were of the size that were respirable by the lung. While workers had occasional eye or mucous membrane irritation, there was little evidence of any lower respiratory health conditions. Conclusion: since almost all of the generated CI particles are not respirable, add’l. stud. of CI in lab. animals are not needed. Illus.
