ABSTRACT
By immersion of the human body in very cold water, hypothermia occurs, followed by a incapacity of resistance to cold water and, in a very short period of time, a sensation of cold is felt at muscle and nerve level, thus losing the capacity of self-rscue and swimming. Another consequence of hypothermia is the risc of ventricular fibrilation and cardiac arrest.Similar costumes/ suits are made out of Lycra, ensuring it fits the figure, also its flotability and comfort. Another type of material, that protects swimmers during harsh meteorological and cold water conditions is neoprene. The paper presents studies regarding different clothing structures assigned to swimming and rescueing suits on the sea, in order to establish an optimal structure, providing human body comfort and protection. These are intended for the personnel from navy petroleum industry, by using them during transportation by hellicopter or by ship to the drilling platform and for rescue in case of damage. For these reasons they should assure sea water impermeability, decreased thermal conductibility, strength to diluted solutions of petroleum-chemical products, reduced flammability level, mobility and flotability, as well as dressing in a short time. Comfort analyses were performed, for different clothing structures, in order to choose the optimal variant.
