How to dispose of corrosive and other chemically contaminated solid waste:
Sharps:
‣ Work under an exhausted area, to avoid inhaling chemical fumes.
‣ Place the waste into a hazardous waste bag, available in waste disposal room W2312.
‣ Secure the end of the bag.
‣ Double-bag, by placing the waste into a second hazardous waste bag.
‣ Fill out and attach a hazardous waste tag (available in waste disposal room W2312.)
‣ Place the waste in the waste disposal room W2312 for pickup.
Sharps should be disposed of in the sharps collection box. This is a large, plastic container is located near the
flammables waste containers. When the container is full, notify an INRF/BiON staff member. The container will
be put in a box and taped shut; the entire box will be disposed of at once, and replaced with a new box.
Sharps should not contain hazardous chemicals; i.e., beakers should not contain liquid photoresists or corrosives.
If you have a sharp object contaminated with chemicals, place the object into a box (an empty wafer box will do),
tape it shut, and treat as solid hazardous waste, according to the procedures above.
