Analysis of the Accidental Release of Chlorine

Abstract

Due to its properties, chlorine is one of the highly toxic substances used by humans. This gas attacks the respiratory system, eyes and skin. In higher concentrations, its inhalation leads to death. It is mainly used in water treatment plants where it guarantees a bacteriologically safe water in water supply systems. It is also used as a disinfectant and bleaching agent.

The use, transport and storage of chlorine may pose serious hazard associated with its uncontrolled release from technological installations or tanks. The level of this threat will depend on the run of the release scenario or meteorological conditions. The article presents an analysis of the hazards associated with the uncontrolled release of chlorine. The ranges of zones with dangerous level of gas concentration are presented as a result of its instantaneous and continuous release.

Estimation of changes of lower limbs reactivity among mountain cyclist under the influence of sauna treatment - abstract

Abstract

Background: Elaborated system of neuromuscular connections gives to a human ability of body control, possibility to move and perform any complicated moves. The issue of neuromuscular conduction appears more frequently in physiotherapy, biological restoration or, widely perceived, sport training. Physiotherapists often wonder how sauna treatment, mainly used in biological restoration, influence on changes of its conduction and, on which level of a rehabilitation, training process or biological restoration should it be used. The aim of this paper was to check how an organism would react after methodically conducted sauna treatments in a form of whole body biological restoration.

Material/Methods: Competitors of cycling group GR AIRCO Team participated in research. Twelve men were classified and divided onto two age groups. On the basis of questionnaires personal details as well as basic antropometric parameters were collected. Tool used to measure reactivity was chosen to research method: Reactivity Measure MCZR/ATB 1.0.

Results: Analysis of variance of following measurements did not show any statistically crucial differences between the group under the age of 30 and over 30 (p>0,05). Results are shown respectively for right leg, left leg, both lower limbs tested simultaneously with the division onto age groups. Analysis of variance show increase of reactivity for all tested participants after sauna.

Conclusions: Sauna treatment among cyclist has impact on a rate of lower limbs reactivity tested simultaneously with impulse differentiation to an appropriate legs.
