Phosphate coatings are one of the most important methods in preventing metal corrosion, especially iron alloys. The high interest in this method for industrial applications is mainly due to the low costs associated with the phosphating solution component and technological process. Considering this aspect and the advantages offered to the materials (corrosion resistance, good adhesion, wear resistance), this study evaluates the potential of using the phosphate coating method in health and safety applications. Therefore, the deposition of a layer of zinc phosphate on the steel surface used in the manufacture of components for personal protective equipment was approached. Firefighters, during rescue/evacuation operations, use protective equipment for fall arrest, whose accessories (hooks, carabiners) are made of steel. Due to the low corrosion resistance property of carbon steel, these accessories must be replaced frequently. This paper aims to analyze the possibility of improving the corrosion resistance of carbon steel in a fire extinguishing solution. Accordingly, the electrochemical behavior of two different types of coatings was studied by electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM). In the literature, different corrosion evaluating methods or systems have been considered, and up until now, there has been no previous study to have approached the corrosive behavior of C45, phosphate C45, and painted phosphate C45 immersed in fire extinguishing solution.

This paper work presents the model for forecasting the exposure risk of workers to hand-arm occupational vibrations, which has been achieved in the PN 07 45 01 18 Project from within the framework of the NUCLEU/2012-2013 Program.This project is of national and European interest, in order to increase occupational health and safety level and to ensure sustainable environmental quality and comfort at work.

The integrated method for an internal efficient auditing of occupational health and safety applicable to complex work systems found in the hydroelectric power generation has been developed within the Project PN 07 45 01 12 of NUCLEU Program/2010-2011. The documentation regarding the appliance procedure of the internal auditing method for the hydro-construction companies is structured in two parts: the first part which comprises the "Work instruments" and the second part, which comprises "The reporting instruments". The method can be used for diagnose analyses in order to assess the global occupational health and safety level as well as for determining the safety risk in OHS field, case in which the base of the probability function related to the states of insecurity can be prognosed with a certain accuracy, the depreciation level of the safety status by estimating the exceeding probability of the value for such a status. In order to determine the safety risk in OHS field there has been carried out the adjustment of the law for the probability of representative/maximal sample values (values related to the insecurity states) obtained from the 21 checklists used in OHS auditing of the analysed objectives from within AHE Surduc-Siriu, to the Gumbel theoretical law of probabilities.

This paper presents the research results on the development and implementation of a traceable and efficient system which is characterized by a high accuracy level, transposed within a specialized IT application in order to properly implement certain sampling schemes required for assessing the conformity of civil use explosives and pyrotechnic articles, in compliance with the

In order to have a proper image of the seismic effect generated by blasting works performed in quarries, the assessment methods applied before starting the blasting activity using explosives for civil use have to take into account as many information as possible with regard to blasting conditions, type of explosive, blasting technique, characteristics of the environment in which the explosive is detonated and in which the seismic waves are generated. Given the complex mode of propagation of seismic waves in the vicinity of quarries, the assessment process may show differences between anticipated values and those measured when performing blasting in quarries. The differences ascertained highlights the importance of seismic measurements in situ, the appropriate way to establish the safety level in carrying blasting in quarries with regard to the seismic effect. This paper presents the results obtained by applying the empirical formulas for estimating the seismic effect and the evaluation of the seismic effect by applying methods and criteria based on the results recorded to the seismic measurements made in quarries. The results obtained according to the requirements of the general standards or other technical regulations, make possible to observe the level of risk regarding the seismic effect for the purpose of applying technical measures to reduce it if the situation requires.
