State and Federal regulations require that all containers holding hazardous waste be closed except when it is necessary to add or remove waste. The term “In-line” waste describes the process where chemical waste flows through tubing from a machine into a collection container. The tubing is hard connected from the machine and fits into a specially designed cap that meets closed container requirements. Typically, High Performance Liquid Chromatography (HPLC) and Inductively Coupled Plasma (ICP) instruments generate waste in this manner.
Pictured below are two examples of non-compliant in-line waste assemblies. Inserting waste lines into an open bottle top (a missing cap), or sealing a container with parafilm does not constitute a closed container. Additionally, drilling holes through an original cap and inserting waste lines through the cap does not meet the regulatory intent of a closed container.
HMM is assisting waste generators in complying with this important regulation by supplying at no cost an in-line waste collection systems. To order, contact HMM at 763-4568 and provide the following information:
- The number of in-line waste kits your lab will need
- The location of your waste containers and your contact information
- Additional fittings can be requested by HMM
