  1. Loading Procedures
Step 1. Ensure that the vehicle is securely braked, chocking wheels if necessary.
Step 2. Contact the local supervisor to ensure that the cargo is of correct specification and quantity.
Step 3. Where safety or fire fighting equipment is required, it should be positioned upwind of the tank.
Step 4. Make earth connection from tank earthing point to local earth positions.
Step 5. Check that the hose connections have the same thread or fitting as the tank connections. Ensure that the correct joint rings and gaskets are used and that they are compatible with the cargo.
Step 6. Check if a Cleanliness Certificate or Gas Free Certificate is required (depending on the previous cargo).
Step 7. Open manlid and examine tank/outlet valves for cleanliness.
Step 8. Check relief valves are in sound condition.
  1. Loading Through Manhole
 
Step 1. Refer to section on Loading Procedure
Step 2. Check that all tank bottom valves are closed.
Step 3. Open manlid and insert hose into tank.
Step 4. Secure hose to stop possible whiplash.
Step 5. Load tank to required level. Check constantly for leaks in hoses and connections.
Step 6. Drain hose and remove from tank.
Step 7. Close manlid and tighten down.
Step 8. Refer to Section  After Loading
 
  1. Loading Through Top Outlet
Step 1. Refer to section on    Loading Procedure 
Step 2. Check that all bottom valves are closed.
Step 3. Remove top outlet blank flange. Both hose coupling to top outlet flange.
Step 4. Connect vapour return line and open valve to vent tank.
Step 5. Load tank to required level. Check constantly for leaks in hoses and connections.
Step 6. Drain hose, close top outlet valve and remove hose from tank. Replace top outlet blank flange.
Step 7. Close airline valve, disconnect vapour return line and replace blanking cap.
Step 8. Refer to Section  after loading 
  1. Loading Through Bottom Outlet
 
Step 1. Refer to section on Loading Procedure
Step 2. Remove bottom outlet blank flange or cap, connect hose ensuring connection is correct and tight. Open valves.
Step 3. Connect vapour return line and open valve to vent tank.
Step 4. Open valves. Load tank to required level. Check constantly for leaks in hoses and connections.
Step 5.  Tanks with single bottom outlet valves:
Close valve and then drain hose.
Disconnect hose and replace blanking cap  Tanks with foot valve and
-external valve 
-Close  foot valve.
- Drain hose.
-Close external valve.
-Disconnect hose and replace blanket cap or flange.(This sequence is important to ensure that no product remains between foot valve and external valve).
Step 6. Close airline valve and disconnect vapour return and replace blanking cap.
Step 7. Refer to Section
 
  1. After Loading
Step 1.  Clean and stow the supply and return hoses, replacing caps and blanks.
Step 2.  Ensure that all tank fittings are correctly closed and capped and any cargo spillage removed.
Step 3. Remove earth connection.
Step 4. Replace safety equipment.
Step 5. If required, seal tank and fittings in accordance with Customs requirements.
Step 6. Check that the tank container is properly labelled for the product loaded, and that any redundant labels have been removed.
 
  1. Discharge Procedures
 
Step 1.  Ensure that the vehicle is securely braked, chocking wheels if necessary.
Step 2.  Contact the local supervisor to ensure that there is adequate space in the receiving tank. If product is already present in the receiving tank check that it is identical to the cargo being discharged.
Step 3. Where safety or fire fighting equipment is required, position it upwind of the tank.
Step 4. Make earth connection from tank earthing point to local earth positions.
Step 5. Check that the hose connections have the same thread or fitting as the tank connections. Ensure that the correct joint rings and gaskets are used, and that they are compatible with the cargo.
Step 6. Check appropriate facilities exist for the draining of hoses and valves.
Step 7. Check the setting of the valves to the receiving tanks.
Step 8. For discharge by pumping or by gravity ensure that the danger of implosion is avoided by opening the manlid (or airline valve to vapour return line if closed system is being used). Ensure that venting is not prevented by any solidified cargo in the airline or relief valves.
Step 9. For discharge with top pressure ensure a gauge is visible and in a serviceable condition to monitor the pressure applied.
Step 10. It will assist discharge through top or bottom outlet if the tank is sited to drain towards the rear.
Step 11. Notify the station supervisor when the tank is ready for discharge.
Note: For cargoes being carried under an inert gas blanket, see section on Gas Blanketing.
