摘要

Possible hazards that may arise from the outdoor use of two smoke generatingdevices, specifically the DM-45 HC smoke generator and the recently developed RA-90 instantaneous smoke concept, are investigated. To accomplish such a task, it is necessary to know the concentration versus time profiles of the most hazardous compound in the smoke clouds generated by these devices. The concentration of zinc chloride in clouds generated by RA-90 and DM-45 in two typical weather situations is estimated. The DM-45 HC smoke generator produces smoke with markedly higher maximum concentrations of zinc chloride particles than the RA-90 instantaneous smoke concept. The maximum time personnel may be exposed to the highest zinc chloride concentrations is also markedly longer for the DM-45.
