[Audio] Potable Water Introduction This presentation is intended for employees who operate Potable Water Trucks/Carts and Water Cabinets at ASAK facilities. ASAK employees may not operate Potable Water Trucks, Carts or Water Cabinets without prior classroom training..

[Audio] Introduction Potable water storage tanks vary in sizes and types, the capacity can range from 50 gallons to 450 gallons of potable (drinking) water. The potable water-servicing unit is designed to accommodate all modern aircraft. The Potable Water Truck/Cart is used when either the hose at the gate where the aircraft is parked is too short or when the aircraft is parked at a remote parking spot away from the main terminal.

[Audio] Contamination avoidance ASAK will not allow the same agent to service both the potable water system and the lavatory system on any aircraft during their workday. An employee that services the lavatory system will not be allowed to service water during that work day. This is to prevent any possible contamination of the potable water. dnata will not allow the same agent to service both the potable water system and the lavatory system on any aircraft during their workday. An employee that services the lavatory system will not be allowed to service water during that work day. They will only be able to service the water the following day after having showered with soap and water. The uniform used must be washed with soap and water. This is to prevent any possible contamination of the potable water. It is recommended that one employee service the water for all the aircraft during their shift and another employee service the lavatory only for all the aircraft during the same shift..
