The health risk level in operating rooms is correlated to the safety levels of microclimatic parameters, thermal indices, anesthetic gases and microbiological parameters. The objective of this study was to estimate the staff and medical service management compliance with the suggestions resulting from monitoring. Methods: The environmental conditions of 38 different operating rooms in the Sicily region, Italy, from January 2011 to December 2020 were monitored. The results were compared with specific standards suggested by national and international laws and guidelines. Results: Almost all microclimatic and microbiological parameters were outside the limits. The monitoring of the anesthetic gases showed that 5.6% of sevoflurane measurements exceeded the limit values. Conclusions: Constant environmental monitoring is an essential element for maintaining optimal living conditions in the working environment. The compliance of staff with guidelines and rules is a fundamental parameter for achieving this objective.

Construction projects are risky in both physical implementation and management. The characteristics of the risk reinforce the necessity of efficient management to increase the chances of success without commitment to its goals. This study explores the correlation of delay and the schedule performance index (SPI) to evaluate the risk of a construction project completed with time overruns. The hypothesis that the SPI of projects with a delay is distinct from those projects without a delay is assumed. A database with 19 elements was used to test this hypothesis and to calculate limit values to the SPI. Therefore, the risk of delay will be small when the observed SPI is greater than the superior limit and large when the SPI is below the inferior limit. The simplicity involved in the calculation of these values showed an advantage in comparison with other methods of risk evaluation. Another strong point observed is that any company can determine the value of risk by considering its own history and support decisions like doing corrective actions.

A general problem in the vicinity of industrial compressors is the noise generated in the working environment by their operation. A large number of workers suffer from hearing problems caused by exposure to high levels of noise in the workplace. Thus, legal provisions regulating occupational noise exposure aim to reduce the risk of hearing loss by reducing noise level, the most effective measures being those applied directly to the noise source combined with the use of hearing protection. Quantification of noise exposure level and mitigation of occupational hazards generated by it at each workplace is required in order to prevent accidents and occupational diseases. The current paper analyses how noise generated by industrial compressors influences worker’s activity. Prevention of noise exposure must be based on noise level measurements. In this sense, the purpose of the paper is to analyse noise measurements performed at a compressor hall and to compare the values obtained with limit values set by in force legislation, in order to apply the best technical organizational methods for lowering noise exposure and increasing acoustic comfort in order to improve working conditions of those working in the compressor hall.

Water is the essential element to develop and maintaining life, that is why the adoption of means of conservation of this essential resource is necessary. In Brazil, the ordinance No. 2914, from December 12th, 2011, of the Ministry Of Health establishes microbiological parameters, which determinate its quality, verifying its potability in order not to offer health risks. The research analyzed five samples from two different wells, placed in the same district of Grajaú-MA. The physical-chemical conditions were analyzed by the following parameters: total alkalinity, chlorides, total hardness, pH, iron, ammonia, chlorine, oxygen consumed, water turbidity by quick tests with the potability kit ALFAKIT and the microbiological conditions by the methodology of the multiple tubes based on the most probable number (MPN), besides seedlings on selective culture means. The results obtained in this research show that the samples of groundwater from five analyzed spots do not match the legislation, because they do not fit to the potability standards. This way, new analysis must be made, mainly microbiological and biochemical tests, to, this time on, adopt means that allow a proper treatment to this water that is used by the local communities.

Chemical air pollution in dental clinics consists of the emission of gases and particulate matter (PM), both generated by dental equipment and tooth tissues. One basic application of Erbium Laser devices is cavity preparation on human teeth due to its strong affinity to water and hydroxyapatite. The objective of this study was the evaluation of indoor air quality during the application of an Er:YAG laser, as a dentin removal instrument, in a Dental Clinic. Particulate Matter (PM) was measured using the standard method of EN legislation. In order to measure total Volatile Organic compounds (VOCs), a portable monitor was used. In the first experiment, PM10 and PM2.5 concentrations were increased by approximately 10 and 15 times, respectively. From the second experiment it can be concluded that neither of the measured particle concentrations exceeded the recommended indoor limit values while windows were open, although laser influence was still detectable. Within the limitations applied herein, it was found that Er:YAG laser activity for hard dental tissue removal was associated with high PM and TVOCs concentration values in the working environment, under insufficient or no ventilation. Physical ventilation in the aforementioned setting proved to be an important key factor in improving air quality, as both PM and TVOCs concentrations decreased significantly.

To date, year August, 2014, as Benghazi, Libya is in a time of conflict depicting a war zone environment, the researcher conducted a study to capture the moment and experiences of foreign national nurses currently deployed in the country performing their duties as healthcare providers. Despite the raised Alert level 4 warning given by the government, meaning "full evacuation mode" from Libya, most nurses refused to be repatriated and stayed to continue serving in Libya. A selected group of sixty-three (63) nurses of different nationalities, working in three (3) different hospitals at the heart of Benghazi, described their present deployment risk level and resilience. Deployment risk level is measured by the Deployment Risk and Resilience Inventory (DRRI) utilizing two of its subscales (C and G) - Difficult Living and Working Environment Scale (Deployment Environment) and the Perceived Threat Scale (Deployment Concern). On the other hand, resilience is measured by the Connor-Davidson Scale. Findings revealed lower risk at exposure to events or circumstances representing repeated or day-to-day irritations and pressures related to life, revealed more perceived threat, but highly resilient during deployment at the war zone. Furthermore, no correlation was found between deployment risk (deployment concern) and resilience, negative low correlation between deployment risk (deployment environment) and resilience, and no significant difference in resilience was observed between genders. Checking the nurses’ current status of deployment risk and resilience in Libya, gave light to future implications on nursing profession.

Workers involving in a manual task (e.g. lifting, pushing, pulling, etc.) are subject to a musculoskeletal disorders (MSDs) risk. The risk is even worse should the workers are not working in a good body posture while facilities and working environment are not ergonomically designed. Thus, it becomes significant for the workers to have a normal body posture while performing tasks. In addition, they also should be equipped with facilities and working environments that are ergonomically designed. CV. XYZ is a garment industry which produces apparels and other clothes. CV. XYZ has several work stations, and one of them is a film-making (screen printing) station. There are 20 work elements in this station, where all of them are a manual task. This research aims to investigate and evaluate over working condition, facilities and working environment at film-making station which later will be quantified into MSDs risk level. For this purpose, this research will employ Rapid Entire Body Analysis (REBA) to measure MSDs risk of the worker in this station. From this evaluation, it will suggest a creation of ergonomic aid tools which aims to reduce the risk of MSDs level. Those aid tools are a desk, a chair and a lorry that are designed by considering body posture and anthropometry principles. A simulation analyisis will be performed by using a mannequin pro software so that the comparison of the MSDs risk level prior and after the improvement can be obtained. Research finding shows that after implementing the suggested solution, 15 out of 20 work elements show a reduction of REBA score, and lowering the risk of MSDs.
