The implementation of the occupational health and safety management system according to OHSAS 18001/2007 in a Moroccan telecommunication company

Integrated environmental, health and safety management systems are a new management paradigm in modern organizations. These systems are built on the ISO 14001 and OHSAS 18001 standards, based on risk prevention and the precautionary principle. The study is carried out in a telecommunications company in Morocco. The objective is the definition of an approach that will promote the protection of its employees against the risks they face and not only prepare them for obtaining safety certification. It has become necessary to have a new approach to occupational safety, which is part of the overall management of the company, and this project has touched him. In fact, this study has tried to guarantee the best working conditions and the presentation of the employees' rights, as well as to reduce the indirect costs resulting from occupational diseases and accidents at work. In other words, the internal audit carried out demonstrated compliance with the main requirements of OHSAS 18001 regarding environmental, health and occupational safety management

Synthesis, Characterization, DFT, and Thermogravimetric Analysis of Neutral Co(II)/Pyrazole Complex, Catalytic Activity toward Catecholase and Phenoxazinone Oxidation

The pyrazole-pyridin-2-amine, as a tridentate pyrazole ligand, and its neutral Co(II)/pyrazole complex were prepared using a direct method with a high yield. The desired pyrazole ligand and its complex were subjected to several physicochemical and thermal analyses; moreover, the DFT-like optimization of MEP, HOMO/LUMO, and TD-DFT correlated well with their experimental relatives. Additionally, the oxidation catalytic activities of the Co(II)/pyrazole complex, such as the catecholase of catechol to o-quinone and the phenoxazinone of 2-aminophenol to 2-aminophenoxazinone, were also evaluated under mild RT conditions and atmospheric oxygen
