Dust and Contaminants: Risks, Prevention and Occupational Health Surveillance in Cleaning Activities

Cleaning and sanitization activities in the workplace can involve exposure to dust, airborne contaminants, chemical and biological agents, and other risk factors. Assessing environmental conditions and working methods is therefore essential to protect the health of cleaning staff and to define adequate prevention and Occupational Health Surveillance programs.

What are the risks for cleaning staff?

During cleaning activities, exposure can derive not only from detergents and other products used, but also from the presence of dust, allergens, microorganisms and contaminants on surfaces or in the air. Dusting, handling materials and sanitization can in fact promote the dispersion of elements with possible irritant, allergic or infectious effects. Added to these factors are the risks associated with the use of equipment, awkward postures and other operating conditions. The analysis of specific risks must consider the tasks actually performed and the characteristics of surfaces, materials, procedures and working methods in all the environments where cleaning staff operate, bearing in mind that biological risk may also be present in activities where agents are not deliberately used but are potentially present in the workplace.

What do the regulations require?

The reference framework remains Legislative Decree 81/2008, which requires the employer to assess all risks to workers' health and safety. Exposure to chemical agents is covered by Title IX, while risk from biological agents is governed by Title X: in both cases, the assessment must consider the characteristics of the agents, the methods and duration of exposure, and the conditions under which the activity is carried out. This thorough analysis leads to adequate prevention and protection measures, including operating procedures, hygiene measures and, when necessary, the use of appropriate PPE - Personal Protective Equipment.

Why is Occupational Health Surveillance important?

Here too, Occupational Health Surveillance is the key tool, as it integrates risk assessment with monitoring of workers' health status. The Occupational Physician identifies potential vulnerabilities, evaluates the effects of exposure in relation to the tasks performed, monitors the health of cleaning staff over time, correlates any disorders with occupational exposures and defines health protocols consistent with the risks present, promoting prevention-oriented behaviors and measures. Environmental monitoring can also help assess exposure to biological risk, through air and work-surface testing that also makes it possible to verify the effectiveness of cleaning and sanitization procedures.

What can SAPRA Occupational Medicine do?

We support companies in managing Occupational Health Surveillance and assessing specific risks, with personalized programs for cleaning staff. The support of the Occupational Physician makes it possible to define health protocols consistent with exposures, monitor workers' health over time and help identify the most effective prevention measures. Proper risk management means knowing the exposures, monitoring them and acting promptly to protect the health of workers, strengthening regulatory compliance and corporate welfare.
