Standard Operating Guideline RELAY PUMPING OPERATIONS Date Issued: February 19, 2020 Rescinds: March 29, 2019 Section: Incident and Emergency Operations File Code: G-RELA PURPOSE To provide all Toronto Fire Services personnel with a guideline for relay pumping operations. RESPONSIBILITY All personnel are responsible for understanding relay pumping operations and must be capable of performing this task. Company Officers are responsible for ensuring relay pump operations are properly established and carried out. The Incident Commander is responsible for ensuring a Water Supply Sector Officer is assigned. Water Supply Sector Officer responsibilities are set out in TN 104.2.7 Water Supply Sector GENERAL Relay Pumping shall be set up when excessive pressures would be required by a pumper to move water from the supply to the fire scene (greater than 1400 kPa maximum, or when Net Discharge Pressures are limiting the amount of water supplied). For relay pumping operations 100mm supply hose shall be used. Source Pumpers shall be no more than 30 meters from a hydrant. Source Pumpers shall utilize all available ports of a hydrant and use 100mm hose for the connections. Distance between pump apparatus in a relay shall not exceed 12 lengths (180 meters) of 100mm hose when a single supply line is used. When relaying to an Aerial waterway (Aerial with no pump or straight into a Quint’s waterway), the maximum amount of hose between the Supply Pumper and Aerial/Quint shall be a maximum of 30 metres (100 feet). Page 1 of 2  Standard Operating Guideline If the Aerial is equipped with its own fire pump (Quint) and the supply pumper is feeding it, this distance can be increased to a maximum of 12 lengths (180 meters) because crews have positive control over their own discharge pressures. Pump operators involved in a relay shall: Remain in frequent radio communication with the respective Sector Officer and other apparatus in the relay Ensure a minimum 140 kPa residual pressure is maintained (if using a pressurized source) The Incident Commander should appoint a Water Supply Officer to be responsible for water supply and pump operations as per TN 104.2.7 Water Supply Sector.
