This article examines modern techniques for the visualization of latent and weak fingermarks, with a specific focus on the occupational health hazards faced by forensic specialists within law enforcement agencies when handling chemical developers. The analysis centers on commonly used yet potentially hazardous substances, including ninhydrin, cyanoacrylates, iodine, fluorescent reagents and fingerprint powders. These reagents pose documented risks of toxic, carcinogenic and irritant effects through inhalation or dermal contact, with additional considerations regarding their environmental toxicity. It is emphasized that approaches to safety in law enforcement agencies often lag behind the introduction of new chemical techniques into expert practice. In this regard, it is pointed out that it is necessary to strictly follow the regulated protocols for handling hazardous reagents at all stages: from the preparation of working solutions to waste disposal. Paramount importance is placed on the mandatory use of personal protective equipment (PPE) for the eyes, respiratory system, and skin, alongside the essential requirement for laboratory spaces to be equipped with forced-air ventilation systems. The conclusion substantiates the position that continuous professional training and regular safety briefings on the protocols for fingerprint examination are integral components for preserving the health and long-term operational capacity of forensic personnel. It is further noted that the efficacy of forensic units is a cornerstone for the overall success of law enforcement operations, thereby inextricably linking specialist well-being to broader public security outcomes.
