Identify the potential hot zone pattern of minimum 100’ to a maximum 500’ around the delivery hose and connections points. Locate valve which will be used to transfer the ammonia from the delivery truck to the system. The operator should verify there is enough room for the ammonia inventory that is to be charged into the system, to do this may require the transfer of ammonia from vessel to vessel. Remove the cap or plug from the valve and install proper delivery connections. Reel out enough delivery hose to reach the charging connection and hook it up. Position the refrigeration operator in the machine room near the fill location and position the delivery truck operator at the truck delivery valve. The charging process must be within sight and must be supervised/monitored at all times. The driver and responsible refrigeration person must be present during delivery. Open the delivery hose valve slowly and check for leaks (if there are no leaks go to next step). Open the system charging valve slowly at the hose connection. If there are no leaks, start the delivery process. Monitor the system until the delivery process is complete. Bleed the liquid ammonia between the delivery hose valve and system valve to an approved container. Disconnect the delivery hose and rewind it. Remove the charging connection and replace the plug or cap. Sign the shipper with the ammonia of ammonia delivered. Record the amount of ammonia received- update the Hazmat Inventory Statement. Close the delivery hose valve.
