Peaks, Means, and Determinants of Real-Time TVOC Exposures Associated with Cleaning and Disinfecting Tasks in Healthcare Settings

Source : Annals of Work Exposures and Health.
Cleaning and disinfecting tasks and product use are associated with elevated prevalence of asthma and respiratory symptoms among healthcare workers; however, the levels of exposure that pose a health risk remain unclear. The objective of this study was to estimate the peak, average, and determinants of real-time total volatile organic compound (TVOC) exposure associated with cleaning tasks and product-use.

Occupational and work-related respiratory disease attributed to cleaning products

Source : Occupational and Environmental Medicine.
Objectives Exposure to cleaning products has been associated with adverse respiratory outcomes. This study aimed to investigate the medically reported incidence, trends in incidence and occupational determinants of work-related respiratory disorders attributed to cleaning agents and to explore the role of ‘Quantitative Structure Activity Relationships’ (QSAR) in corroborating the identification of chemical respiratory sensitisers. Methods Respiratory diagnoses attributed to cleaning agents were extracted from The Health and Occupation Research (THOR) surveillance network, 1989–2017. Incidence, trends in incidence and incidence rate ratios by occupation were investigated. Agents were classified by chemical type and QSAR hazard indices were determined for specific organic chemicals. Results Approximately 6% (779 cases) of the (non-asbestos) THOR respiratory cases were attributed to cleaning agents. Diagnoses were predominantly asthma (58%) and inhalation accidents (27%) with frequently reported chemical categories being aldehydes (30%) and chlorine/its releasers (26%). No significant trend in asthma incidence (1999–2017) was observed (annual average change of −1.1% (95% CI −4.4 to 2.4)). This contrasted with a statistically significant annual decline in asthma incidence (−6.8% (95% CI −8.0 to −5.6)) for non-cleaning agents. There was a large variation in risk between occupations. 7 of the 15 organic chemicals specifically identified had a QSAR generated hazard index consistent with being a respiratory sensitiser. Conclusion Specific occupations appear to be at increased risk of adverse respiratory outcomes attributed to cleaning agents. While exposure to agents such as glutaraldehyde have been addressed, other exposures, such as to chlorine, remain important. Chemical features of the cleaning agents helped distinguish between sensitising and irritant agents.

Over-exposed : standard occupational exposure limits must be reduced for workers on extended work schedules

Source : Canadian Occupational Safety.
In Canada, about 30 per cent of all employees now work non-standard schedules. Increasingly, they require people to work longer days. The move to extended shifts raises the possib ility of increased exposure to chemical hazards over a longer day. By understanding how to use the different adjustment models available, safety professionals can keep the chemical exposure of workers within reasonably safe levels.

Potential Hazards of Additive Manufacturing

La transformation additive, communément appelée impression 3D, est de plus en plus répandue dans l’industrie. Les industries de l’automobile, de l’aérospatiale, des dispositifs médicaux et de l’électronique l’utilisent déjà, et on s’attend à ce que les applications biomédicales augmentent. Un nouvel article de chercheurs du NIOSH, publié dans le Journal of Occupational and Environmental Hygiene, met en lumière les procédés de transformation additive, identifie les dangers potentiels et discute des besoins de recherche pour protéger les travailleurs.

L’application généralisée des produits nanotechnologiques et la probabilité croissante d’exposition en milieu de travail font de la compréhension des effets de ces matériaux chez les travailleurs exposés une priorité de santé publique et professionnelle. Cette revue systématique vise à faire le point sur l’état actuel des connaissances sur les effets nocifs possibles induits par les ENM chez les humains afin de déterminer le profil toxicologique de chaque type d’ENM et les biomarqueurs potentiels pour la détection précoce de ces effets chez les travailleurs.
