Cleaning - Nettoyage


Quel nettoyage pour quel local ?

A l'entrée de chaque laboratoire ou bureau se trouve une fiche de porte,

sur celle-ci, un N° de PNL (Procédure de Nettoyage de Local)

est défini et renseigne les nettoyeurs de ce qu'il faut nettoyer, comment et à quelle fréquence.

des couleurs informent sur le type de local:

VERT = bureau à nettoyer

ORANGE = laboratoire à nettoyer

ROUGE = labo spécial, entrée interdite pour le personnel de nettoyage

BLEU =  local technique, entrée interdite pour le personnel de nettoyage

La liste des tâches et la fréquence est définie dans les PNL ci dessous (information à titre indicatif, les PNL peuvent être modifiés par UNIBAT):

Normal Waste

What is the definition of normal waste?

Laboratory's waste not contaminated by biological agents (cell or bacterial cultures, pathogens, GMO, viruses, etc.), not soiled by chemicals or toxic products. This includes: gloves, household paper, filters, tubes, prepackaged pipette tips, etc.

and what to do with normal waste?

1   Paper, documents
     Treatment: place in the dedicated boxes in each office and laboratory.
     When you box is full, every Thursday evening, you can put these boxes in the corridor, the staff of the washing facility will take them every Friday morning to bring them  in the dedicated container, on level 1, outside the building (western exit).

2   Glass
    Definition: Pasteur pipettes, empty bottles, broken crockery, etc.
    Treatment: clean the glass correctly and place it in the "glass" bins in the laboratories.
    Caution: if the glass was in contact with GMO or pathogens (see this point on special waste )
    Once full, these bins are to be emptied in the dedicated container, on level 1, outside the building (western exit), by the laboratory staff.

3  Expanded Polystyrene (EPS)
    Definition: chips, box, etc. of Expanded Polystyrene (EPS).
    Treatment: place in the dedicated container in the waste local on each floor, the staff of the washing facility will collect it and bring his content on the level 1, outside the building (western exit).

4   Hard Plastic

     Définition: Tips Holders, boxes...

     Treatment: place in the dedicated container in the waste area, outside the building (western exit), there is a special container for  hard plastic recycling.

5   Paperboard
On the 3rd, 4th and 5th floor of the CIG in the west side cleaning room, located between both toilets, there is a metal cart where folded empty cardboard boxes can be stored.
When the cart is full, the personal of the washing facility puts it in the waste area, level 1, outside of the building.

6  PET
   Treatment: place in the dedicated bags, then the personal of the washing facility brings these bags in the waste area on level 1, out of the western exit of the building.

7  Aluminum
Treatment: place in the dedicated boxes, then the person in charge for the floor brings these boxes in the waste area on level 1, out of the western exit of the building.

8   Other

Treatment: place in the blue 30 liters dustbins bags labeled "UNIL" when these bags are full, put them outside of the labs, the cleaning staff will bring these bags in the waste local.
Caution for pipette tips: place them in the small plastic bags on the bench, close the bag once full, place it in the 30 liters waste black bags.


How would I trash the SPECIAL WASTE?

Biological 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.).

2.   Treatment:
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.

Chemicals Waste

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).

Sharps Waste

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.

     Person responsible for "sharps": Carlos Luzolo Soba, phone 39 51


The rule of incompatibility of storage of compounds and products is applicable in the same way as for laboratory waste.


Different sort of waste bags

  • - The red bags are intended for contagious waste as currently used, class 2 or above.

            These bags are changed and taken down to the washroom by researchers or washroom staff where they are autoclaved.

  • - The yellow bags are for any waste labs with the exception of contagious waste,

            These bags are sealed by the researchers and taken down to the yellow containers by the cleaning staff.

  • - The blue bags are for the usual waste, as office, kitchen, toilet waste, as it is for household waste.

           These last bags are changed and taken down to the corresponding containers by the cleaning staff

The description, the categories mentioned below are extracts from the laws in force at Unil and the Swiss Ordinance on the Movement of Waste and are therefore not exhaustive. This description does not in any way exempt consultation of the official documents of Unil and the Swiss Confederation. CIG staff are required to inform themselves about the procedures to be followed to treat waste or to classify it with the various managers named in Genopode's general guidelines.

Your PI's, your Genopode Safety Coordinator and L'unil Safety Officers can help you if you have any questions or doubts.  In general, safety data sheets provide valuable assistance for the treatment, storage and classification of waste.
