Drums must be inspected weekly for leaks and to ensure their general condition. There must be adequate aisle space in the drum storage area to allow the inspection. This area must be free of unnecessary clutter, such as storage of equipment around and on the drums. Finally, drums are to be kept closed at all times, except when waste is being added. Drums with a removable top must have the lid in place with the ring tightly bolted.
Bungs are to be in place and screwed in tight.
This will prevent leaks if the drum is tipped over. For drums where waste is frequently added, funnels can be installed into the bung opening but must be secure and have a lid or other similar device that closes. Portable tanks are defined as containers having a capacity greater than 110 gallons. Portable tanks have the same operating and labeling requirements as drums. Tank material and the ancillary equipment must be compatible with the stored waste and cannot cause the tank to rupture, leak, corrode, or any other failure.
