Research on the Possibility of Reducing the Concentration of PM10 and PM2.5 Dust Fractions in the Process of Visualizing Fingerprints with a Light Fingerprint Powder – Argentorat

Summary/Abstract: The aim of this paper is to present the results of a study, carried out in a forensic science laboratory, on the effectiveness of a station for fingermark development with fingerprint powders on nonporous substrates (SDU – 513), in terms of increasing the safety of persons exposed to the harmful effects of dust during the visualization of the above-mentioned traces with a light powder – argentorate. The authors demonstrate that the fan-activated equipment repeatedly reduces the concentration of dust fractions PM10 as well as PM2.5 in the air above its working surface. They also stress that the SDU – 513 station does not completely eliminate the risk of, among other things, dust entering the lungs. With the above in mind, they conclude the article with a series of recommendations to ensure safe and hygienic working conditions for the operators of the said equipment
