The mobile environmental laboratory was located in a fuel distribution station located on a heavy traffic national road in Petro?ani City, Hunedoara County (Romania) to investigate dust and gas pollution, as well as dispersion of pollutants to nearby homes, using the AUSTAL VIEW software. Measurements were performed over a period of eight hours in two working days in order to better capture the movement of air masses and the dispersion of measured pollutants. In the event of accidental spills of chemicals or chemi...

Explosive atmospheres may occur both in underground mining, as well as in surface industries such as the oil and gas, chemical, petrochemical, wood or baker industries, basically in all industries which extract, process, use, transport or store flammable substances. Within the European Union, Directive 2014/34/EU regulates the placing on the market of equipment, protective systems and components intended for use in such hazardous atmospheres. In this regard, for proofing the compliance with the essential safety re...

Noise is a "by-product of technological metabolism", omnipresent in most workplaces, representing one of the discomfort factors for personnel working in the presence of this noxae. Knowledge of risks generated by exposure to noise specific to each activity carried out, allow quantification of the effects on workers such as: masking, auditory fatigue, sound trauma, acute hypoacusis, professional deafness. Accidental exposure to noise leads to auditory fatigue, which is a transient and reversible phenomenon, but pro...

A known and often used method of insulation is represented by soundproof sponge, having the role of sound absorption and improvement of acoustics. The insulating sponge is used in recording studios, Radio TV studios, music rehearsal rooms, for upholstering acoustic enclosures having the role of acoustic correction. The aim of the study is to improve acoustic characteristics of a room that was originally used as an office and is now used as a music rehearsal room and recording studio, making determinations of noise...

Underground mining remains one of the most dangerous occupations in the world, and coalmining is known for its high accident rates. In this paper we aim to present an overview of safety in the extractive industry and we will present statistics on known accidents. The repeated occurrence of explosions in underground mining raises questions about the measures taken to prevent their occurrence. Hazard identification and risk analysis are necessary to identify adverse events that may lead to a hazardous situation, to ...
