June 9, 2013 – Volunteer firefighters attend a firefighting foam class at the Delaware State Fire School in Dover, Delaware. Various evolutions were conducted involving a gasoline tanker and pit. These special props allow for a realistic event involving a gasoline fed fire. Mill Creek Fire Company has two fire engines equipped with firefighting foam. The foam concentrate is carried in a separate tank and is automatically mixed with water resulting in the white foam. Hockessin Fire Company (DE) and West Grove Fire Company (PA) participated in the exercise with Mill Creek Fire Company.
