The safety of operatives, the general public and the environment depends upon the responsible operation of tank containers during loading, discharge, storage and transport.
It is essential to ensure the following before loading or dispatching a tank container.
The tank is the correct type and in the proper mechanical condition   The tank interior and exterior is suitably clean  
Ensure that the tank container being used is suitable and approved for the carriage of the cargo concerned and has been well maintained, inspected and tested in accordance with the regulations. It should also have successfully completed Pre-trip inspection.

It should be noted that compatibility is a two way process - the substance(s) loaded must not affect the integrity of the tank shell, fittings, gaskets etc. and conversely, the substance(s) loaded should not be able to pick up a contaminant from any part of the tank shell, fittings, gaskets etc. which could set off a dangerous reaction in the substance(s).
Ensure that any residue from previous cargoes is removed or is compatible with the product to be loaded. The exterior of the tank, especially the labels and markings, must not be contaminated or obscured with cargo spillage.
The gross weight is not exceeded  
The gross weight of the vehicle when loaded must not exceed the weight limitations imposed by regulation, nor must the maximum gross weight under the CSC approval be exceeded.
The tank has correct marking and placarding   All operations are competently supervised 
The correct identification and hazard warning markings must be attached in their appropriate positions on the container. Marking & placarding which are no longer applicable must be removed. The personnel in charge of loading or discharge must be in possession of written instructions detailing the safety requirements and emergency procedures in relation to the handling of the cargo and must have been trained to the required level of competency.
The tank is filled correctly   The gas or air supply is clean  
The ullage (free space in loaded tank) must comply with the regulations.
