Abstract |
Tests were conducted on 30 hair dryers for the release of asbestos (1332214) fibers into the effluent air to evaluate potential consumer exposure, for the Consumer Product Safety Commission. A hair dryer test system was developed, consisting of a clean air source, a sampling duct assembly, several types of monitoring equipment and filter samplers. Generated samples were assessed by transmission electron microscopy capable of performing energy dispersive analysis of x-rays and selected area electron diffraction. Of the 30 dryers evaluated, 23 were home use hand-held appliances, three were table-top hooded models, one was a hobby heat gun, and one was a heavy duty commercial salon style dryer. The airborne asbestos concentrations generated by these dryers ranged from 0 to 0.11 structures/cubic centimeter and the mass concentrations ranged from 0 to 7652 nanograms/cubic meter. No significant differences were noted whether the dryers were operated at high heat or at cycled heat. |
