We investigated the charge generated on bedclothes (cotton and polyester) during bedding exchange with different humidities and the ignitability of an alcohol-based hand sanitizer (72.3 mass% ethanol) due to static spark with different temperatures to identify the hazards of electrostatic shocks and ignitions previously occurred in medical facilities. The results indicated that the charging of the polyester bedclothes may induce human body potential of over about 10 kV, resulting in shocks even at the relative humidity of 50%, and the human body potential of higher than about 8 kV can cause the risk of the ignition of the hand sanitizer...

The assumption that safety hazards in construction projects are independent leads to a weak foundation for risk assessments, and related management strategies may be biased. Therefore, understanding interdependencies of hazards is critical to risk assessment in construction safety. This study proposed a qualitative-quantitative hybrid approach to delineating hazard associations. Based on the hazard network model for an elevator installation, we identified the characteristics of the hazard network and determined critical hazard types based on the hazard associations...

Risk graph (RG) is the widely used method to evaluate the safety integrity level (SIL) of safety instrumented systems (SIS). However, the subjective opinion based conventional RGs cannot provide successful results in the problems of risk parameters, such as shortages or lack of data, hence, the output of a conventional approach lacks enough reliability. In this paper, we introduced fuzzy improved risk graph (FIRG), an extension of the fuzzy set theory, to deal with the possible ambiguities during the SIL study and increase the reliability of conventional RGs...

In 2015, the United Nations defined sustainable industrialization as one of seventeen sustainable development goals. In this article, an analysis is performed to assess the opportunities for ergonomics to contribute toward sustainability in the manufacturing industry. To that effect, a case study was carried out in a maquiladora of electronic components in the northwestern region of Mexico. The investigation was developed in four stages: a) diagnosis, b) planning, c) implementations, and d) verification of results...

In this study, responses of biodynamic human body models to whole-body vibration during vehicle ride were investigated. Accelerations were acquired from three different body parts, such as head, upper torso and lower torso, of 10 seated passengers during a car ride while two different road conditions were considered. The same multi-purpose vehicle was used during all experiments. Additionally, by using two widely-used biodynamic models in literature, a set of simulations were run to obtain theoretical accelerations of the models and they were compared with those obtained experimentally...

INTRODUCTION: Reducing human error is an important factor for enhancing safety protocols in various industries. Hence, the analysis of the likelihood of human error in nuclear industries such as radiopharmaceutical production facilities has become more essential. METHODS: This cross-sectional descriptive study was conducted to quantify the probability of human errors in a 99Mo/99mTc generator production facility in Iran. First, through expert interviews, the production process of 99Mo/99mTc generator was analyzed using hierarchical task analysis (HTA) method...

This study aimed to provide a greater understanding of the systemic factors involved in coal mine accidents and to examine the relationships between the contributing factors across all levels of the system. Ninety-four extraordinarily major coal mine accidents that occurred in China from 1997 to 2011 were analyzed using the human factors analysis and classification system (HFACS). The empirical results showed that the frequencies of unsafe behaviors, inadequate regulation, and failure to correct unsafe behaviors were the highest among five levels, fourteen categories, and forty-eight indicators, respectively...

The purpose of this study was to examine the pattern of urinary protein excretion induced by three consecutive days of wildland firefighting. Eighteen male active duty military personnel were served as the participants. All testing consisting of three consecutive days was conducted at a Northwestern USA fire camp. All participants consumed military-based foods containing 2620-2864 kcal/day. The work activity was evaluated with an accelerometer in association with body weight and hydration markers over the experimental period...

BACKGROUND: Microsurgery is a surgical procedure requiring a high degree of precision and is commonly facilitated through the use of an intraoperative microscope. When operating the microscope system, the long-term posture leads to musculoskeletal disorders in surgeons, and seats are commonly employed to diminish these problems. The present study was conducted to evaluate musculoskeletal discomfort during work with a saddle seat in comparison with conventional seats for microscopic work...

Contractor selection is one of the major concerns of industry managers such as the oil industry. The objective of this study was to determine a contractor selection pattern for oil and gas industries in safety approach. Assessment of contractors based on specific criterion and ultimately selecting an eligible contractor preserves the organizational resources. Due to the safety risks involved in the oil industry one of the major criterion of contractor selection is safety which is considered by managers today...

This study was conducted to determine the most appropriate surface processing techniques (SPT), environmental conditions (EC), and surface roughness (SR) to minimize the risk of slipping while pedestrians walk on the floor covering of rocks in barefoot and with shoes. Coefficients of friction (COF) and values of SR were found by using five different types of rocks, four SPT and two (ramp and pendulum) tests. Results indicate that the parameters that affect the COF values of rocks include SR, EC, and SPT. Simple linear regression was performed to examine the relationship between the values of the COF and the SR...

INTRODUCTION: Minimally invasive surgery (MIS) has shown significant benefits for patients and healthcare systems. However, due to the poor ergonomic adaptation of operating rooms and surgical instruments, most surgeons suffer from pain caused by musculoskeletal disorders (MSDs). METHODS: A descriptive survey on MIS surgeons working in different surgical specialties has been carried out in Hospital Valdecilla (Spain). The aim is to determine the prevalence of MSDs using a personal interview and the standardized Nordic questionnaire...
