Investigation of the occupational health and safety conditions in Hellenic solid waste management facilities and assessment of the in-situ hazard level
Due to tenuous working conditions and working accidents in the past, sufficient safety measures for the personnel in certain solid waste management facilities are deemed a necessity. Besides the fact that such facilities are equipped with heavy machinery associated with safety risks, the working environment poses additional health risks to the personnel, due to their exposure to various waste-derived emissions. Therefore, it is required to establish and preserve the safety and hygienic conditions but also to equip and train their personnel during all waste treatment and management stages. Presented...
Fentanyl Exposure Risks for Law Enforcement and Emergency Response Workers
Fentanyl is a powerful synthetic drug that is similar to morphine and heroin, but is 50 to 100 times more potent. Fentanyl and its analogs, such as carfentanil, can pose a potential hazard to law enforcement, emergency medical personnel, and firefighters who could come into contact with these drugs through the course of their work day. While there are important questions about the risks of different types of exposures (and resultant health effects) that might occur during law enforcement and emergency response activities, workers involved in these types of activities leading to potential exposures...
DERMaL eToolkit
Emergency response personnel are often at risk of getting dangerous chemicals on their skin. Despite the availability of numerous high-quality resources designed to guide emergency management and operations personnel, data gaps continue to exist on specific hazards or scenarios. Available resources contain an overwhelming quantity of data on inhalation exposures, but data related to dermal exposures are more challenging to find. Dermal contact is an important exposure pathway and can present significant health risks [Dotson et al. 2015]. The goal of the DERMaL eToolkit is to provide informational...
