Analysis of main environmental components must be appropriate and useful for establishing decision-making elements regarding environment quality, the need for intervention and remediation in major cases, or improvements and development forecasting for local specific situations or subsequent climatic behaviour and composition transformation processes. In this respect, the usefulness of the information gathered from environmental analysis largely depends on how monitoring actions and environmental analysis (inspection and measurement) are planned. Pollutants discharged from use of various technological gases must be measured and analysed to avoid potential hazards and protect vital space and man against direct and indirect effects of noxae. To this end, the current paper aims to analyze certain internationally recommended methods for measuring and monitoring main gases which have negative impact upon the environment and human health, such as physicochemical analysis/evaluation/radiography of gases and dusts from the Jiu Valley urban area's atmosphere, trying to asses the state of the environment in this area.

The manner in which individuals deal with stressful situations depends on several variables. Personality characteristics, event circumstances, preparedness of individual, personal appraisal of events, pre-existing organizational and personal stressors are all key factors. Psychological resistance to stress can be the result of spontaneous evolution, or can be developed through special training, through programs that increase the threshold beyond which functional alterations may occur, resulting from dealing with stressful events. Psychological training can be improved by acquiring specific psychological knowledge and strategies and by indirect experiences with emergency situations and scenarios. Procedures such as stress inoculation, emotional management and stress reduction management, cognitive restructuring, relaxation techniques, problem solving and optimization of interpersonal relationships can be learned and used by individuals. Along with training in conditions as close as possible to future reality of interventions, psychological training can contribute both to the success of intervention and rescue operations and to appropriate management of emotions generated by emergency response. The current paper details issues regarding the implementation of a psychological training program for intervention and rescue personnel in toxic/ flammable/ explosive environments, in order to test it and to identify adjustments needed to be made for optimizing it, as well as a series of theoretical fundaments for each of the five modules of the program.

Intervention and rescue activities require knowledge of the real situation in the affected area as accurately as possible. Therefore, the physical exploration of this area is at the same time necessary and risky. The use of drones from a safe distance can protect the intervention team from exposure to unknown hazards. Endowment of the drone with a suite of sensors such as high resolution cameras, thermal imaging, infrared, and gas detection equipment permits vital data to be transmitted to the base of intervention. Hazardous areas can be studied from different angles, from an altitude that provides a panoramic view, and make available rescuers information about dangers encountered, state of access routes, number of people caught by the event, and control or protective measures that need to be taken. The current paper presents the methods for use and control of drones in support of rescue actions, resulting from tests performed by the research team, trained and certified to use drones, within the National Institute for Research and Development in Mine Safety and Protection to Explosion-NIRD INSEMEX. It was demonstrated that a drone which carries a multigas detector and a high definition video camera can help rescuers which intervene in an area with fire/toxic/flammable hazard. For such a mission, a drone must be capable to flight a long time, to carry the multigas detector and to flight secure without visual contact and without autonomous flight support in case of GPS signal lack. Flights in such conditions impose high power engines with 6-8 propellers for fine adjustments.

Intervention and rescue activity in special conditions may be conducted only by trained and authorized personnel using individual protective breathing equipment. While working with the insulating respiratory device, there are a number of factors that make work stressful. As a rule, those working under protection of the insulating respiratory devices, besides carrying on their back a device weighing 14-18 kg, are also subject to great difficulty, in terms of securing their own safety, saving lives, quick-acting under heavy microclimate conditions (high heat and humidity). For interventions demanding predominantly physical effort, in high temperature and humidity environments, where work processes involve large muscle groups, changes in physiological indicators, during or immediately after effort, have been observed, especially in the cardiovascular system and respiratory system. In this respect, the paper presents a research on changes in physiological parameters (pulse and blood oxygen saturation) of intervention and rescue personnel in situations where they have to intervene in high temperature and humidity environments. To that effect, several teams of mine rescue brigadesmen were monitored throughout their training within the National Institute for Research and Development in Mine Safety and Protection to Explosion INSEMEX Petroşani training facility, which may generate the most unfavourable conditions that can be encountered in various emergency situations.

Considering the expertise gained by the experts of INCD INSEMEX Petrosani in the organization and coordination of mine rescue operations based on an well-determined processing algorithm, it is possible to develop a modern and efficient tool for the management of emergency situations due to major accidents in the underground mining industry in order to diminish the period of time necessary to take good decisions in case of need. The paper presents this software in detail on a strict chronological order, as well the stages necessary to be considered by the members of the commandment in order to safely remove the effects of major accidents and provides, whenever necessary, lists with the specific objectives that have to be touched during certain stages.
