<p>Na prossecução dos objetivos do milénio da ONU, o aumento e melhoraria do acesso a sistemas de saneamento básico seguros e sustentáveis continuam a ser uma prioridade de intervenção crítica e essencial para salvaguarda da saúde humana e qualidade de vida das populações. O desenvolvimento, implementação e monitorização de Planos de Segurança, aplicados às diferentes fases do ciclo urbano da água, são uma estratégia crucial, recomendada pela OMS, para prevenção, análise e mitigação do risco associado a perigos e eventos perigosos com impacto nocivo na saúde pública e no meio ambiente. O objectivo deste trabalho é dar um contributo metodológico para a análise do risco em Planos de Segurança de Águas Residuais (PSAR), por meio quer da formulação de um novo método semiquantitativo de avaliação do risco em PSAR e sua aplicação a um caso de estudo, quer de uma abordagem integrada do sistema de saneamento, incluindo as suas interações com a respectiva bacia hidrográfica. Concluiu-se que o nível e tipologia do risco dependem da abrangência geográfica da bacia hidrográfica considerada, a qual influencia não só a diversidade dos perigos e eventos perigosos identificados, mas também a definição das medidas de controle do risco a implementar, resultantes da necessária abordagem de barreiras múltiplas, no sentido de eliminar ou minimizar os riscos para os diversos utilizadores e operadores de um sistema urbano de águas residuais.</p><p> </p><p align="center">RISK ASSESSMENT METHODOLOGY IN WASTEWATER SAFETY PLANS. A CASE STUDY</p><p>ABSTRACT</p><p>In pursuit of the UN's millennium goals, increasing and improving access to safe and sustainable sanitation systems remains a critical intervention priority to safeguard human health, life quality and population wellness. The development, implementation and monitoring of Safety Plans, applied to the different sections of the urban water cycle, is a crucial strategy, recommended by WHO, for the prevention, analysis and risk mitigation due to hazards and dangerous events with a harmful impact on public health and the environment. This work intends to make a methodological contribution for risk analysis in Wastewater Safety Plans (WWSP), through a comprehensive approach to the full sanitation system, including its catchment watershed interaction, and the proposal of a new semi-quantitative risk assessment method applied to a case study. It was concluded that the risk level and typology depends on the geographical scope of the considered watershed, which significantly influences not only the diversity of identified hazards and dangerous events, but also the definition of risk control measures to be implemented, arising from a multiple barriers approach, in order to provide a risk mitigation for the several wastewater system users and operators.</p>

The Impact

Entertainment places have special structure; large fire load, personnel-intensive features, and function layout often change in the process of operation, so the fire risk level will change frequently. The current fire risk assessment studies for only one stage in entertainment places without considering the impact of risk factors at different stages. For this situation, this paper presents a fire risk assessment method in entertainment places based on full life cycle, divides the entertainment places into different stages, analyzes risk factors at different stages, and then uses the method of Gustav to get the fire risk levels of different stages. The assessment results show that the level of fire risk in entertainment places are different at different stages, you can take the appropriate risk control measures against fire risk factors at different stages, which has important guiding significance for fire risk management in entertainment places.

Background and Aim: This study tries to assess the risk level of fire in an educational environment by FRAME software in a practical method. Then, some effective strategies were proposed to reduce the risk level of fire and secure the environment as much as possible. Methods: In this practical study, the fire risk assessment was carried out in an educational environment by Fire Risk Assessment Method for Engineers (FRAME) ؛ this risk assessment was done in three sections including building and contents, residents and activities. It was tried to gain the highest fire security for the educational environment by using practical and logical control measures. Required data was gathered by studying and monitoring the situation, observation, interview, referring to available documents and measuring some parameters, regulatory inventory and checklist according to the requirements of the FRAME executive instruction. The calculation was done by FRAME software. Results: The results showed the risk levels of fire for the educational environment were unacceptable in residents (R=2.7) and activities (R=3.8) sections; although some parts such as laboratories, libraries and partitioning parts in the building section had a high-risk level (R> 1). Some preventive measures were recommended for reducing the risk level of fire and improving the security of situation by considering some effective factors؛ the results showed a significant reduction in the risk level of fire in all three sections within the acceptable level (R< 1). Conclusion: The results showed that the FRAME method can assess and determine the quantity of risk level and provide suitable controlling methods to improve the security of fire in the educational environment by considering the opportunities and challenges of the existing environment.

BACKGROUND: The COVID-19 global pandemic brought several challenges to occupational safety and health practice. One of these is the need to (re)assess the occupational risks, particularly, biological risks. OBJECTIVE: The purpose of this work is to promote guidance to occupational safety and health practitioners when conducting a biological risk assessment in this context. METHODS: The main steps of the biological risk assessment are explained with some inputs regarding the novelty posed by SARS-CoV-2 and an example of a qualitative risk assessment method is presented. Also, its application to two different activities was exemplified. RESULTS: In both cases, the assessment considered that vulnerable workers were working from home or in medical leave. The results showed low or medium risk level for the assessed tasks. For medium risk level, additional controls are advised, such maintain social distancing, sanitize instruments/equipment before use, use proper and well-maintained PPE (when applicable), and promote awareness sessions to spread good practices at work. Employers must be aware of their obligations regarding biological risk assessment and OSH practitioners must be prepared to screen and link the abundance of scientific evidence generated following the outbreak, with the technical practice. CONCLUSIONS: This paper could be an important contribution to OSH practice since it highlights the need to (re)assess occupational risks, especially biological risk, to ensure a safe return to work, providing technical guidance.

Risk Assessment Method

Successful implementation of Health and Safety (H&S) systems requires an effective mechanism to assess risk. Existing methods focus primarily on measuring the safety aspect; the risk of an accident is determined based on the product of severity of consequence and likelihood of the incident arising. The health component, i.e., chronic harm, is more difficult to assess. Partially, this is due to both consequences and the likelihood of health issues, which may be indeterminate. There is a need to develop a quantitative risk measurement for H&S risk management and with better representation for chronic health issues. The present paper has approached this from a different direction, by adopting a public health perspective of quality of life. We have then changed the risk assessment process to accommodate this. This was then applied to a case study. The case study showed that merely including the chronic harm scales appeared to be sufficient to elicit a more detailed consideration of hazards for chronic harm. This suggests that people are not insensitive to chronic harm hazards, but benefit from having a framework in which to communicate them. A method has been devised to harmonize safety and harm risk assessments. The result was a comprehensive risk assessment method with consideration of safety accidents and chronic health issues. This has the potential to benefit industry by making chronic harm more visible and hence more preventable.

The Impact

Stakeholders in the system of food safety, in particular federal agencies, need evidence-based, transparent, and rigorous approaches to estimate and compare the risk of foodborne illness from microbial and chemical hazards and the public health impact of interventions. FDA-iRISK (referred to here as iRISK), a Web-based quantitative risk assessment system, was developed to meet this need. The modeling tool enables users to assess, compare, and rank the risks posed by multiple food-hazard pairs at all stages of the food supply system, from primary production, through manufacturing and processing, to retail distribution and, ultimately, to the consumer. Using standard data entry templates, built-in mathematical functions, and Monte Carlo simulation techniques, iRISK integrates data and assumptions from seven components: the food, the hazard, the population of consumers, process models describing the introduction and fate of the hazard up to the point of consumption, consumption patterns, dose-response curves, and health effects. Beyond risk ranking, iRISK enables users to estimate and compare the impact of interventions and control measures on public health risk. iRISK provides estimates of the impact of proposed interventions in various ways, including changes in the mean risk of illness and burden of disease metrics, such as losses in disability-adjusted life years. Case studies for Listeria monocytogenes and Salmonella were developed to demonstrate the application of iRISK for the estimation of risks and the impact of interventions for microbial hazards. iRISK was made available to the public at http://irisk.foodrisk.org in October 2012.
