OP-21: Hazardous Waste Management
Does the institution have strategies in place to safely dispose of all hazardous, universal, and non-regulated chemical waste and seek to minimize the presence of these materials on campus?:
A brief description of steps taken to reduce hazardous, universal, and non-regulated chemical waste:
It is Wellesley’s goal to (a) reduce these wastes; (b) reuse or recycle them, when possible, and (c) manage them safely, and in accordance with the law. Waste is managed by the EHS Office and the Science Center Safety Officer.
A hazardous waste contractor provides turnkey services for Wellesley College to safety and appropriately manage it’s hazardous waste. EHS manages the contract for the majority of campus operations. Motor Pool manages waste oil at the garage. Science Center staff manage waste generated in the science center to include hazardous chemical waste, radioactive waste, sharps, biological waste, etc. Health Services manages biological waste generated at the infirmary.
Universal waste is handled by a specialized licensed disposal contractor.
Similar steps are taken with non-regulated chemical waste.
In general for hazardous, universal, and non-regulated chemical waste, outside contractors are responsible for the removal of any waste they create. It is recommended that clear guidelines be established on project scope documents.
A brief description of how the institution safely disposes of hazardous, universal, and non-regulated chemical waste:
Segregate hazardous chemical waste according to compatibility. Choose appropriate impervious containers for storage. Flammable wastes should only be stored in 1 gallon containers except for 2.5 gallons stored in fireproof rated cans. All containers must be properly labeled with dated waste labels. Complete chemical names must be used. Hazard info should be noted. For hazardous waste, date the container when full or when ready for disposal. Only one container at a time may be used to collect one waste stream (one type of waste). The container will have a maximum capacity of 55 gallons. Waste containers must be kept tightly closed at all times except when pouring in waste. Funnels may only be inserted when pouring in waste.
Universal Waste must be kept in containers or packages. Containers must be kept closed and lack evidence of leakage, spillage, or damage. It is recommended that box dividers are used to avoid breakage. Designated storage areas must be set up to manage universal wastes on campus. Waste lamps must be put in appropriate storage at the end of each work shift and placed in designated universal waste accumulation area(s). The waste itself or the package must be labeled:“Universal Waste - _____________” (type of waste).
Chemical waste containers should be physically separated according to this compatibility chart.
