ANSWER: All OSHA/DOT-approved Sharps containers will typically have a “Fill Line” on the label in front where it is easily seen. Do not overfill Sharps containers above the fill line. Sharps needle containers are considered complete when they are about three-fourths (3/4) full; look for the fill line on the container. Once a Sharps needle container is ready to be disposed of, close and seal it, and make sure the lid is securely closed and secured. We recommend using medical tape across the lid to make sure it doesn’t open. All complete Sharps containers should be placed in your biohazard medical waste box for your disposal company to remove at a later time.
