This 40-hour course is designed for firefighters who are assigned to or may be assigned to operate fire department apparatus in the normal course of their duties. This course is designed to develop firefighters understanding of mechanical principles of fire pumps and their controls, principles of water and water distribution systems, intake and discharge hydraulics, fire stream production, relay pumping operations, care and maintenance of pumper apparatus, and troubleshooting. Students will practice producing effective fire streams from hydrants, relay operations, and static water sources. Students will also practice determining pump discharge pressures for hydraulic situations that range from single line problems to multiple-line relay operations to provide a solid understanding of fire ground hydraulics and practical solutions to apply these concepts to their department.
