4. Acetone, IPA and ethanol are provided by the MNF. These chemicals are typically present in each fume hood inside the proper dispenser. If the dispensers are empty, the users should fill them with the corresponding chemicals. These chemicals can be found in:
– SoN cleanroom: in the safety cabinet in the inorganic-chemistry zone. The empty chemical containers should be first left open under a wet bench so that the left over solvent is evaporated and then placed in the lower shelve of the cleanroom trolley in the cleanroom corridor.
– CenTech I cleanroom: the chemicals cupboard under each fume hood. If not, the other supply is in the two top shelves of the chemicals cupboard in the deposition zone. The empty chemical containers should be transferred to the entrance area of the gowning room.
5. All the other chemicals have to be self-managed by the users and the groups.
6. If not already present, the user/group should send, prior to bring it to the cleanroom, a chemical safety datasheet to the MNF admin. This datasheet will be uploaded in the MNF website.
7. All chemicals have to be labelled indicating the chemical name, the chemical composition, the hazard statements and pictogramme, the date of the entry, the name of the working group and the user.
8. A color-coded label indicating the waste category has to be attached to each chemical bottle:
– Acid: red, – Base: black, – Solvent: white.
9. Storage of the chemicals:
– SoN cleanroom: All the chemicals should be stored in the chemical cabinet in the Inorganic-chemistry zone.
– CenTech I cleanroom: New solvent bottles have to be stored in the chemicals cupboard in the Deposition zone. Resists have to be stored in the resist cupboard next to the fume hood in the Preparation zone. Bases have to be stored in the base cupboard next to the fume hood in the Preparation zone. If the space allows, open solvents bottles can be stored under the fume hoods chemicals cabinets.
10. It is forbidden to use, without prior consent, the chemicals of the other users or work groups.
11. Bottles and chemicals should be transported using the metallic buckets. The buckets are available next to the transfer hatches.
12. Never leave unlabelled chemicals unattended. This is especially true for chemicals used during regular operation. Always write your name, phone number and the name of the chemical on a piece of cleanroom compatible paper (available in the cleanroom) and stick it in front of the working area.
Prior to the operation, the user should check whether waste containers with enough capacity are available or not. If not, they have to contact the Safety officer or the mnfadmin.
There are different schemes for collecting the solids wastes based on the following categories:
– Contaminated wastes: All materials that were in touch with acid, base and polymers should be considered to be contaminated. These materials should be disposed in blue barrels which are available in the Preparation, Inorganic-chemistry and Photolithography zones. In the Inorganic-chemistry zone, there are two blue barrels available for acid and base wet benches.
– Sharp objects: Broken samples should be disposed of in the dedicated containers in each cleanrooms. Other sharp objects such as broken glassware should be disposed of in the contaminated waste bins (blue barrels).
– Pipettes: disposable pipettes should be disposed of in the contaminated waste bins (blue barrels). Pipette tips should be collected in the dedicated sharps bins or reggie bins (available in each of the allowed wet benches).
– Uncontaminated waste: All other materials are considered uncontaminated and they should be disposed into metallic pedal bins. Slightly wet to dry wipes that have only be in contact with IPA, Acetone, Ethanol and water and nitrile gloves that were not in direct contact with the contaminated chemicals are suggested to be considered in this category.
1. Under each wet bench, liquid waste containers for solvents, acids and bases based on the application of the wet bench are available.
2. High concentrated acids or bases need to have their own dedicated waste container. Do not dispose a high concentrated acid or base in the waste container of other acids or bases! Users should check the availability of the suitable waste container before they start their operation.
3. Liquid waste containers should not be filled more than 3/4 of their total capacity.
4. Users are responsible for transporting full liquid containers to:
– SoN cleanroom: Trolley
– CenTech I cleanroom: the chemical cupboard in the Deposition zone. and to inform the safety office or the MNF admin about the full container.
5. Empty waste containers are available in:
– SoN cleanroom: below the acid wet bench in the Inorganic-chemistry zone. – CenTech I cleanroom: the chemical cupboard in the Deposition zone.
6. Users should properly label each new waste container.
7. For any further question concerning the waste management, please refer to the safety officer.
The following procedures should be followed in case of a chemical spillage:
– If the spill hits the operator or other users:
1. Users personal safety is of the most importance.
2. If possible, the user should evacuate the cleanroom and inform the other users about the presence of a chemical spill.
3. The contaminated clothing should be removed and the affected skin area cleaned. If the chemical is a strong base or acid, the affected area should be rinsed with water for 10-20 minutes. A body shower is available in:
– SoN cleanroom: in the cleanroom corridor (two showers)
– CenTech I cleanroom: the corridor outside of the cleanroom, next to to the cleanroom door.
4. If any chemical comes in contact with or around the eyes, they should be washed with lots of water. Eye showers are available in the zones where wet benches are present.
5. The user should call the mnfadmin or an experienced colleague for assistance.
– If the spill does not affect anyone and all the users are in safe conditions:
1. Spill kits are required to be used. Spill kits are available in each zone where wet benches are present. The exact location is indicated with the corresponding sign.
2. Wearing protective gloves and in the case of acids or bases, face shield and apron is necessary before trying to clean the spill.
3. The area around the spill has to be isolated using the absorbent pillow and the tissues in the spill kit to prevent spreading.
4. The user must inform as soon as possible the MNF staff or, in case of absence, one of the instruments managers. The user must report the chemical composition of the spill, the amount and if people or instruments have been involved.
5. If the spill is a solvent or has a strong odour, the cleanroom should be evacuated.
6. The contaminated surfaced must be cleaned with water once the spill has been completely soaked up.
7. If any glassware is broken, the user should be very careful in removing them.
The purpose of the MNF regulations is to guarantee a safe and functional working environment.
2. Users are invited to strictly follow the MNF regulations and refer to the MNF staff before acting in case of any doubt.
3. In case of violation, the MNF has the right to limit or revoke the status of a user, which include the access to instrumentation, booking system and MNF server. The MNF can use the data present on the MNF server or in the workstations as a proof of violation and/or delete them without being obliged to make any backup.
4. The violation of the regulations and their corresponding reaction are categorized as follows:
