1. Inventory of methods currently available From the regulatory point of view, the main objective of acute toxicity testing is basically to classify chemicals according to their intrinsic toxicity as required by the EEC directive on classification, packaging, and labelling of dangerous substances (Council Directive 67/548/EEC and subsequent amendments). This requirement aims to protect public h...

The prevention of dangerous chemical accidents is a primary problem of industrial manufacturing. In the accidents of dangerous chemicals, the oil gas explosion plays an important role. The essential task of the explosion prevention is to estimate the better explosion limit of a given oil gas. In this paper, Support Vector Machines (SVM) and Logistic Regression (LR) are used to predict the explo...

With modern technological advances, we often find ourselves dividing our attention between multiple tasks. While this may seem a productive way to live, our attentional capacity is limited, and this yields costs in one or more of the many tasks that we try to do. Some people believe that they are immune to the costs of multitasking and commonly engage in potentially dangerous behavior, such as ...

Natural rubber is an indispensable raw material that supplies about half of the world's consumption. The latex extracted from trees composed polyisoprene rubber, proteins, sugars, amino acids, lipids, and minerals. When liquid emanates trees, it comes into contact with bacteria cause to decompose coagulate. To hinder decomposition destabilization process, ammonia other environmental health haza...

A testing strategy for the classification of self-heating substances for transport of dangerous goods is proposed. The strategy was developed based on the tests described and correlations used in the UN Recommendations. It was demonstrated that the value of activation energy of the exothermic reaction has a significant impact on the extrapolation of test results with regard to different contain...

Exfoliated transition metal dichalcogenides (TMDs) such as WS2 and MoS2 have shown exciting potential for energy storage, catalysis and optoelectronics. So far, solution based methods for scalable production of few-layer TMDs usually involve the use of organic solvents or dangerous chemicals. Here, we report an eco-friendly method for facile synthesis of few-layer WS2 and MoS2 nanosheets using ...

In order to protect public health and the environment, the EU legislation has proposed a classification of dangerous substances. Chemicals are classified according to physico-chemical as well as toxicological and ecotoxicological properties. Environmental classification is based on inherent harmful potential of a substance to organisms and on its environmental fate, that is, degradation and bio...

The application of strengths, weaknesses, opportunities and threats (SWOT) analysis to formulation of strategy concerned with the safe carriage of bulk liquid chemicals in maritime tankers was examined in this study. A qualitative investigation using SWOT analysis has been implemented successfully for ships that are designed to carry liquid chemicals in bulk. The originality of this study lies ...
