UMass Dartmouth's EHS Team is committed to providing a healthy and safe learning environment. The goals of our hazardous waste program are to:

•   Protect faculty, staff and students from hazardous wastes exposures

•   Manage all hazardous wastes in an environmentally and safe manner

•   Minimize the quantities of hazardous wastes being generated in teaching and research labs

•   Identify pollution prevention strategies to minimize or eliminate the our overall impact on the environment

•   Comply with federal, state and local regulations

The CITI training course “Lab Chemical Safety” covers the management and safe handling of hazardous wastes. If you are planning to manage hazardous chemical waste in your lab, please take this course at your earliest convenience. Click here to access the CITI program training website! For more information about CITI training requirements, visit the Training Section. 

UMass Dartmouth has partnered with Triumvirate Environmental Inc. to offer onsite hazardous waste removal services. Pickups of hazardous waste from labs are scheduled every Tuesday (Wednesday for satellite campuses). Our hazardous waste technician is generally onsite from 8:00 AM – 12:00 PM. The technician will check each Satellita Accumulation Area (SAA) in your lab and remove containers that are compliant and ready for pickup. 

Hazardous waste within a laboratory must be stored in a Satellite Accumulation Area (SAA). The UMass Datmouth SAA Sign must be posted in close proximity to the location where hazardous waste is generated. Here are some important rules to follow when managing hazardous waste in your SAA:

Hazardous Wastes at UMass Dartmouth are regulated according to regulations of the Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (DEP). In order to decide whether you have a hazardous waste, you must determine whether your waste has certain characteristics or appears on one of several lists. If it does, then you must manage it according to requirements identified in our Lab Waste Guide. If waste you have does not meet this criteria and is not a hazardous waste, please confirm with Environmental Health and Safety whether it is appropriate to dispose of your waste down the sink or regular trash. Although some waste you generate may not be a hazardous waste, it still may be necessary to manage it this way to prevent adverse effects to health, safety or the environment. Refer to the hazardous waste determination table below: 

A waste exhibits the characteristic of ignitability if the waste exists in the following forms:
