The technical rescue unit was founded at the time when a refinery activity was still in the Lendava region. In the company Nafta Lendava at that time, there was still a refinery activity, drilling and extraction of hydrocarbons was intensified. The unit was professionally trained and equipped for interventions in case of an accident, at the level of the mining rescue unit. Due to the need for occasional and periodic cleaning of tanks in which hazardous liquids (especially hydrocarbons) are stored, we also started to perform cleaning activities. Operators are trained and equipped to perform work in an explosive atmosphere. Lack of knowledge, poor equipment and insufficient experience in this kind of work lead to disasters of larger dimensions and serious consequences.
