How does a fire start? What are the main causes of fire? What role do batteries play in causing fires? And how dangerous can aerosols with their flammable propellants become in an emergency? These and other questions were the focus of our fire-fighting exercise in autumn 2025. Robert Gsinn, fire protection officer from the Rosenheim administrative district, was on site for two days. His theoretical training focused on preventative fire protection, what to do in the event of a fire and the correct use of fire extinguishers and fire protection equipment.
The theoretical part was followed by the practical application part. 77 members of the OELCHECK team were trained in the correct use of fire extinguishers. This included the entire process, from unlocking to activation. Employees practised with foam and CO2 extinguishers. Foam extinguishers for fire classes A and B are used to extinguish burning solids and liquids. However, CO2 extinguishers are only approved for fighting fires involving liquids (fire class B). They are the first choice, for example, for use in laboratories, IT systems or electrical and electronic systems.
