Chemical Waste Disposal
Prior to disposal of any chemical waste, our generators (lab personnel) perform a hazardous waste determination on the material. Ewaste, filled out with EH&S waste label and the hazard ID on the label is marked.
As per Hazardous Waste Reduction guide ,Materials which are corrosive, reactive, flammable, toxic, or specifically listed by the EPA are considered hazardous.
CORROSIVE (pH<2 or pH>12)
REACTIVE (oxidizers, water reactive)
FLAMMABLE (flash point <140 F)
TOXIC
LISTED BY THE EPA (F, K, P, U, and D listed materials)
Containers
All waste will be put in appropriate NON-LEAKING containers with lids that are non-leaking, tight fitting and are not cracked, broken, or chemically damaged.
Labels
All unused chemicals in original non-leaking containers with manufacturer’s label will be accepted as is, but at least one filled out waste label is required for the collection of materials.
All other waste requires a hazardous waste label.
Labels are affixed in a manner that does not cover existing labels or markings.
Waste labels for EH&S-provided solvent containers should be put onto the hang tags which EH&S attaches to containers.
Packing
We don’t pack waste in boxes, since waste containers will be visually inspected.EH&S staff will segregate waste according to compatibility.
Handling of specific wastes
-aerosol cans
all aerosol cans are considered hazardous waste.
-photographic darkroom chemicals
used photographic chemicals are considered hazardous waste.
-used oil
used motor oil from internal combustion engine processes can be combined with used oil managed by osu transportation services (motor pool). No other contaminants are allowed.
all used oil produced in laboratory operations, including pump oil, must disposed as hazardous waste.
-organic solvents
organic solvents can be combined by eh&s and reused for off-site fuel or solvent recovery. There is no minimum amount needed for requesting disposal.
When organic solvents are mixed in-lab with other chemicals, the mixture becomes unsuitable for heat recovery and costs will increase.
“other chemicals” include halogenated solvents, acutely toxic material, acids, bases, heavy metals, oxidizers, and pesticides.
Halogenated solvents is separated from other liquids for solvent recovery.
