The Preliminary Analysis of the Plume Produced by CO2 Laser and the Care of Safety
Kao-Chia Yang, Pai-Tsang Huang
Dermatol Sinica 16: 72-76, 1998

This study is to analyze the concentration of dust, and the composition and concentration of chemicals in the plume produced by CO2 laser. Whether or not the dust and chemicals in the plume were harmful to medical personnel was important. Analysis of the dust by using a smoke evacuation unit showed that the concentrations of both the "total dust" and "respirable dust" were below the national permissible exposure limit of 10mg/m3 and 5mg/m3, respectively. Qualitative and quantitative analysis of the chemicals showed that all were well below the national permissible exposure limit. Several carcinogens, such as benzene and ethylene oxygen, were found in very low concentrations in the plume,indicating that the probability of carcinogenesis was not high.We conclude that the quantity of dust and chemicals in the plume produced by CO2 lasers do not constitute a health risk to medical personnel.
