【Things that cannot be treated as laboratory chemical bottles (containers)】
×Those that cannot be removed due to adhesion of harmful substances → Disposal as treatment No. 21 "waste reagent"


※ How many times should a bottle or container be washed with water or a suitable
solvent? Three times!

Chemicals that are water-soluble and that do not react with water → Use water Chemicals that are not water-soluble or that react with water (most Class 3 hazardous materials as defined by the Fire Service Act, with the exception of yellow phosphorus) →Use the suitable solvent

(2) Chemical plastic containers
Example: Washed chemical containers (plastic)

【Items that cannot be processed as lab chemical bottles (containers)】
Containers with hazardous material residue that cannot be removed → Dispose using
Processing Rule No. 23 (waste reagent).

★Disposal method

Labs using the IASO reagent management system should register empty bottles.
Be sure to empty each container and wash the necessary number of times with water or a suitable solvent (*see below). After washing, collect remaining liquid in a plastic tank for waste liquid.
Apply “Washed” stickers → Stickers are available at each department’s Clerical Center.

Precautions
Disposing of bottles without first washing them poses the risk of reactions with rainwater or other chemicals. If told that a bottle is unwashed, take it back with you.
Dry as much as possible.

Glass products (washed)
Example: Washed glass and ceramic lab implements

【Items that cannot be processed as lab chemical bottles (containers)】
Items with hazardous material residue that cannot be removed → Dispose using Processing No. 23 (lab waste).

★Disposal method

★Collection date, time and location

Any time during business hours in the facilities management section (extension 7270), 5th floor, Research Building

★ When mercury is spilled

Contact the Facilities Section (7270) on class days. Contact the disaster

1. Enhance ventilation and do work with a gas mask, protective gloves, protective goggles etc.Mercury evaporates easily! There is a danger of inhaling its vapor.
2. In the case of large amounts, collect with paper, a plastic plate, dropper etc. and put in containers (glass · poly) which can be sealed.
3. For fine droplets of mercury, collect it using tin foil or copper wire (peal the coating off electric wire first)
4. Finally, copper powder or zinc dust (neither oxidized) can be sprinkled on the mercury and,after being adsorbed, can be collected with something like a small broom.
5. Bring the mercury deposits to the Facilities Section (5th floor of the research building).
