There are two typical problems when ED materials are packed in form of plastic drum.The first one is the additional loss because of chemical residue,and the other is empty drums which belong to hazardous waste.Upgrading tanker method to transport ED materials could achieve effectively the goals of zero loss and zero hazardous waste.In order to avoid the risk of adding incorrect materials or blocking pipe,it would need to analysis equipment modification and error proofing systematically for pre-existing painting workshop.Meanwhile,a new strategy was explored to verify the actual pay load because the ED materials were settled by weight,and the purpose was to make sure accuracy and compliance.Finally,some appropriate advice was introduced to guide refinement of management,such as the method of keeping ongoing balance for liquid level of on-site tank,as well as the corresponding solutions to quality abnormity.
