Click   HERE    for RIPA’s guidance on the removal of paints and adherents from steel drum exteriors.   This narrative and pictorial guidance was developed to help reconditioners, shippers and safety regulators understand the processes for preparing steel drum exteriors and the need to protect the steel’s thickness and integrity from excessive treatment (e.g., excessive shot blasting, brushing).  This guidance document is also cataloged on this site under “Resources” and “Industry Data and Standards”.
