Background and purpose: Identification of risk in hospital waste management have a major role in reducing the cost of surplus and preventing the spread of diseases. In this quantitative analysis, we aimed at determining waste components, evaluating hospital waste management, and prioritizing the risks in Sari Fatemeh Zahra Hospital. Materials and methods: We performed a descriptive-cross-secti...
Background and aims: Work environments are constantly changing under the influence of various factors and newer risks are introduced. Rapid changes in science and technology, increasing the complexity of the industry, increased system integration and other factors have been shown to increase total risk in the past few decades. As well, risk management becomes increasingly critical in decreasing...
Background and aims: Work-related accidents each year have a significant impact on worker productivity and ultimately the economy of the society. It is estimated that each year two million workers around the world die due to work-related accidents. And approximately 100 million occupational accidents occur each year in the world. Risk perception as a subset of safety culture show an instant ima...
Since the inception of jack-up rig operations in early 1950s, series hazardous accidents has been witnessed, and losses recorded. These events are approximated to occur at least twice a year. With this statistics, harsh offshore environment demands jack-ups premium quality. Designing self-elevating (jack-up) structure is one that must be founded on well-proven principles, industry-accepted reli...
Exploiting the innate hydrolytic enzyme/s potential of the genus Bacillus for costeffective production of PHAs, using various agro-industrial wastes will contribute to cost reduction and elimination of pre-treatment protocols. PHA producing Bacillus spp. from different rhizospheric soils capable of producing a variety of hydrolytic enzymes were isolated. Two promising isolates: Ti1 and Ti3, fro...
In Taiwan, relevant mid-term plans and projects of mitigating occupational hazards have been launched in recent years in the hopes of lowering the incidence of occupational hazards. In light of the lack of objective methodologies for researches on issues pertaining occupational safety and health, this research aims to explore the priorities of safety and health issues through focal groups, expe...
We report on the ability of bacteria to produce biodegradable polyhydroxyalkanoates (PHA) using oxidized polyethylene wax (O-PEW) as a novel carbon source. The O-PEW was obtained in a process that used air or oxygen as an oxidizing agent. R. eutropha H16 was grown for 48 h in either tryptone soya broth (TSB) or basal salts medium (BSM) supplemented with O-PEW and monitored by viable counting. S...
Background and aims: Hazard identification is a critical factor to ensure safe design and operation of systems in the process industries. Process industries are one of the most complex systems, with a variety of equipment, control systems, and executive procedures. In these industries, the use of hazardous materials as raw materials or products is quite common. Interactions between technical co...
Abstract Introduction: In the absence of proper control, environmental hazards and risks from industries, can be irreparable damages to the environment. Hence, this study with the aim of environmental risks identification and assessment (such as emissions to air, discharges of pollutants into water, the discharge of pollutants in soil, consumption energy, etc) and estimation of control c...
