The Oshkosh Fire Department conducted a hazmat training session to prepare firefighters in the event of an emergency involving dangerous waste. As a part of the training, the fire department needed to find a way to stop the leak in a tanker. According to firefight Kevin Sawicki, they used a pop-up pool to contain the leak and then put a cap on the valve to keep the substance from leaking further. Even though real chemicals were not used during training, officials with the fire department say they believe scenarios are the best way for their crew to learn how to manage a real-life event.
