How would I trash the SPECIAL WASTE?
1. Definition: laboratory waste contaminated by biological agents (bacteria, cells, virus, fungi, GMO, etc.) produced in BSL1 (P1) and/or BSL2 (P2)(plastics, household paper, pipettes, gloves, agar plates, cell culture media, etc.).
BSL1 solid waste: once full, the small plastic bags for biological waste on each bench are to be placed only in autoclavable red bags Biohazard labeled placed on each floor, in culture rooms and in the corridors (2 bags are installed in the corridors on each floor).
a.2 Once closed, these bags are collected by the personnel of the washing facility and autoclaved, before being placed in normal waste bags.
BSL2 solid waste: are also put in red bags Biohazard labeled, but remain in the BSL2 labs. (They are not put in the corridors) The staff responsible for the P2 lab has to bring these bags in the washing facility for autoclavage.
NB: the glassware must be decontaminated and rinsed before being placed with the normal glassware and collected by the personnel of the washing facility. Broken glassware should not be put in the bags to autoclave: special autoclavable boxes for sharps are to be requested at the "magasin central". See also 4.2.2.
Liquid waste: collect liquid waste, decontaminate chemically (Javel) or autoclave, eliminate in the sink.
Please note: the waste, which was chemically treated cannot be put in the autoclave.
Person responsible for "biological waste": Prof Bernard Thorens, phone 39 81
Definition: chemicals, waste contaminated by chemicals or toxic products (including original container).
1. Bring the waste to the collection places on each floor.
2. The various categories of common chemicals are:
• Non-halogenated solvents
• Halogenated solvents
• Photographic solutions (developer and fixer)
• Solid and liquid waste containing ethydium bromide
• Liquid waste containing acrylamid
• Liquid waste containing phenol-chloroform
• Waste containing mercury or mercury salts.
Chemical waste not included in the above categories: contact the person responsible for "chemical waste".
3. When the containers are full, the person in charge for the floor brings them in the dedicated space outside the building (western exit, in the direction of the chemistry building).
Person responsible for "chemical waste": Carlos Luzolo Soba, phone 39 51
Definition: any sharp object (blades, syringes, Pasteur pipettes, etc.).
Place in the dedicated yellow boxes.
Once full, close the box tightly
Bring the box to chemical waste room.
Pay special attention to FULLY REMOVE microscope cover slides from the dishes; they are almost invisible and it can hurt our colleagues in the washing facility.

This special waste has to be disposed of by a specialized enterprise. The responsible will provide the necessary information on this matter.
Responsible: Fabienne Lammers, phone 4136
Mixed waste (chemical, radioactive and biological) must be handled on a case-by-case basis considering the highest risk.
This waste cannot be autoclaved !
