This study was focused on reasons resulting in the explosion in a storage tank with neutral sulphite cellulose in South Slovakia Cellulose and Paper Plant in Štúrovo. With respect to the technology used microbial processes continuously proceeds in the storage tank. It was found that cellulose as well as dilution water are contaminated with microorganisms. Anaerobic bacteria produce explosion gases such as hydrogen and hydrogen sulphide. As a reason of the explosion was the ignition of  H₂ and H₂S mixed with air due to a spark resulting from the electrostatic energy. Hydrogen is formed during every conditions. However, when the time of retention of particles in the tank is prolonged the production of explosion gases significantly increases and can mean the higher risk for the procedure.
