​​The MPW box kits (five boxes, ten bags, and plastic bag closure ties) are available from the NIH Self-Service Store and NIH Stock Catalog (NSN-8115-00-L04-0680). Use 2 bags per box for double containment.

The MPW box MUST NOT be used for disposal of general waste such as soda cans, papers, cardboard, bottles, etc., or storage or moving laboratory equipment, office equipment, or household items. The MPW box MUST NOT contain free liquids. 

How to Setup the MPW Box:

1. ​Fold the flaps down on the outside of the box.
2. Place TWO plastic bags (one inside the other) into the box and pull the bag tops down over the flaps (Only use the two black plastic bags that come with the MPW box).
   
3. A filled MPW box should weigh NO MORE than 40 pounds or be no more than 3/4 full. 
4. Close each bag SEPARATELY. Twist the plastic bag at the top, bend the twisted portion to form a loop, and seal using the plastic bag closure tie.
5. Close the box. Fold Flap A down into the box, fold the B Flaps over Flap A, and push Flap C down to lock with Flap A.
6. PRINT your building, room number, and waste type (pathological or non-pathological) on the box top label area.
