Checklist for Safety Introduction of Students in HCI SU-Management D-CHAB/TM
This checklist applies to all assistants in the HCI. All assistants must to be able to personally explain all of the following information to the students before they start their laboratory work. Work-specific hazards and risks that require special behavior and safety measures must be added to this general safety introduction.
For more information, go to www.chab.ethz.ch/das-departement/services/su-management.html
Checklist for the safety introduction of students: - All students in HCI will receive the double-paged laboratory rules which are integrated in the
HCI Shop Brochure student information instead of the safety handbook. The students must be able to confirm that they have read and understood it. Expectant mothers should first contact the safety department at the following email address before they work in laboratories: [email protected]
- Questions about work safety, health and environment must be sent to the email address of the
safety department: [email protected] - For all other concerns and technical problems the assistants can use the following email
address: [email protected]. Concerns and technical problems should always be described briefly but in detail, in a clear and understandable way.
- Alarm Phone 888: See separate info sheet - Old versions of SHE manuals, laboratory rules and outdated leaflets etc. should always be
disposed of.
- Laboratory Activities: Assistants must explain all dangers and risks that might be en-
countered while working in the laboratories and discuss these with all students. Food is strictly forbidden in the laboratory. In addition to personal protective equipment, all laboratory workers are required to wear lab-appropriate clothing. Food samples for analyses or experiments must be unmistakably labeled as such and stored separately from chemicals.
- Goggles: The wearing of safety glasses is mandatory. Contact lenses are not permitted even
while wearing safety glasses. Students who require corrective lenses or glasses should contact the safety department to receive special goggles for laboratory use.
A contaminated eye must always be rinsed with water for at least 10-15 minutes! Two-helper method: One person holds the contaminated eye open while the other flushes the eye with water.

- Protective Goggle Issues:
There is evidence that standard protective goggles are not suitable for some people, especially those with narrow faces, as there are open gaps in the goggles that leave the face vulnerable to chemical sprays and spills. The so-called “diver goggles” were distributed in all internship rooms in HCI buildings 1-3. We only distributed these goggles to 60% of students in each room. Should any assistants require more, they can be easily purchased from the HCI shop.
These “diver“ goggles were made available for students who work with especially dangerous liquids. After their internship, all students are required to clean and return their goggles to the assistants.
- Check students’ goggles: Before new students can work in the laboratory, all assistants are required to check their goggles to ensure that they fit properly and that no liquids can spray or spill through them. If there are any defective or ill-fitting goggles, the assistant must go to the HCI shop and find a more suitable and well-fitting pair for the student before letting them go to work in the laboratory.
- Prevor Eyewash (Diphoterine solution):
The description for this product can be found on the internet. (www.prevor.com) This kind of eyewash only works when used immediately following an incident. The small (50ml) bottle must be used in the first 10 seconds after an incident. Hence, it is advised that this bottle be carried with you at all times, especially when performing dangerous experiments. In our emergency cabinets, you will find large eyewash bottles (see picture below). These must be used within 1 minute following an incident. If applied properly, do not rinse the eye with water. (See www.prevor.com)

- Stationed Emergency Cabinets: In the event of an incident, each person has to decide for him or herself whether or not they want to help. Those who decide to stay and help must first protect themselves by wearing the proper gear. In each building, there is an emergency cabinet stationed in the hallway with various emergency materials for helpers. The key to the emergency cabinet is in the red box next to it. Simply break the glass and take the key. It is everyone’s duty to inform the Alarm Central (888) in case of an emergency. Helpers must secure the event scene with caution tape to control unauthorized entry until the medical/rescue staff has arrived. It must be ensured that spectators do not hinder the rescue work.
Location of Emergency Cabinets: HC1: In the middle side corridor of the big laboratory D118 HC2: In the side corridor, next to D212 HC3: In the side corridor, next to D312 HC4: In the side corridor, next to E412 HC4: In the first side corridor on the right after the entrance of finger 4 of the H-floor HC5: In the side corridor, next to F512 Inventory of Emergency Cabinet: Protection of respiratory tracts: military gas mask and particle filter mask Protection against heat/fire: Fire-resistant Kevlar gloves Protection against contamination: Hydrofluoric Acid first aid kit ; a cyanide-emergency kit
is deposited at the Alarm Central, disposable protective jumpsuits and various protective gloves
Combating of chemical spillage: High efficient absorption material for chemicals, absorption mat/barrier tape, special absorption powder for HF, quicksilver spillage-kit, plastic bags/empty boxes for contaminated elements
First Aid: HCI first aid staff-box Rescue Blanket: Patient care: civil-protection blankets, rescue blankets Optional: work-specific protective material The emergency cabinet in HC2 + 3 has each 2 defibrillators – 1 in English and 1 in

- Student Laboratories: - Ventilation control: Each laboratory has its own autonomous pneumatic ventilation
system (the pneumatic ventilation system is not accessible for the users as it is located in the vertical duct- Steigzonenschacht). The pneumatic ventilation system regulates the ventilation balance in the laboratory permanently. There is a light negative pressure in the standard laboratories at all times which means that all kinds of accidents stay in the laboratory area and do not spread further in the building. For these reasons, the laboratory and balcony doors should not be left open for prolonged periods. In case of an accident (even in case of foul-smelling emissions), the laboratory has to be evacuated. Balcony and laboratory doors must be kept closed throughout this time.
- Precautions against theft: If there is no staff present in the laboratory, the door must be
locked. ETH is not responsible for stolen or missing private property. - Eye wash / fire extinguisher: The eye shower is integrated above the sink; pull it out to
use it. The eye shower must be washed at least once a week in order to prevent the water in the shower from spoiling or contaminating. There is also a 2kg carbon dioxide fire extinguisher in the laboratory.
- Cooling water modules / cooling water-emergency switch off: The cooling water
modules are unfortunately in poor technical condition. If water comes out of these modules or a broken tube sprays water out, the main cooling water valve must be closed immediately. It is placed in the vertical duct (Steigzonenschacht) in the corridor in front of the laboratory unit and is indicated with a red dot. The cooling water valve itself is also marked with a red dot which you have to close to stop the water breakout. You can open the door with your personal laboratory key. The cabinets with the red dots can always be opened with your personal laboratory key.
- The window of the fume hood is not a notice board. Do not write on the glass and do not
apply sticky notes. - Problematic Gas Module:
- Protection Against Excess Pressure in the Apparatus:
Several accidents at the HCI, which have nearly ended in worst-case scenarios, have been caused by over-pressure of gas pipes or as a result of over-pressure accumulation in various apparatus. Therefore, we urgently suggest the use of safety valves for all hazardous and pressure-delicate apparatus. In particular, we recommend the safety valves from “Lorch” which are obtainable in different variations on www.lorch.de. The safety valve can, among other things, be installed easily on Lüdi-fittings. There is for example the safety valve type 2108 for neutral gas and vapour, operating from 0.3 bar over-pressure (check the website for details). Applications: Over-pressure protection of gas pipes in flash-chromatography-columns, over-pressure protection of gas pipes in alkali metal distillation, over-pressure protection in cases of failure of the gas modules or gas amount regulator in the media column etc. The safety valve should not be applied with vacuums (e.g. the Shlenk line).
The Lorch safety valve can be ordered directly from the laboratory specialist shop. The Lüdi-fittings can also be obtained from the HCI-shop.
With the gas module, you can only set the gas pressure but not the gas volume. For exact gas volume regulations, metering valves (pictured on the right) are available at the HCI shop. These must be attached to the gas module. One of the most common incidents is over-pressure, which occurs when glass devices are directly attached to the gas module. (see the Safety Handbook, Version 2016)

- Waste Management in Student Laboratories:
- Disposal in the laboratories is an issue that the students don`t like. Because this topic is so unpopular, there are many risks present that could cause accidents. Note: The lessons also include the disposal of waste.
- The collection and transport of hazardous wastes is only allowed in suitable and approved containers. Hazardous wastes must be labeled with an UN number and with the associated danger label. For approved and suitable containers the following conditions apply:
- Careful handling, no damage (= loss of UN approval) - The maximum lifetime for plastic packaging is 5 years. The production date is
imprinted on the containers. - Packaging should be used in accordance with the manufacturer's instructions.
Note: Hazardous wastes in inappropriate packaging will not be accepted in the central waste disposal. You can get suitable and approved containers in the central disposal. If you have problems with your laboratory waste disposal, do not hesitate to contact the personnel at the central waste disposal.
- We have been dealing with a material defect with the overpressure valve in the screw caps, which don’t react as they should in cases of overpressure. The first batch of defective caps were recalled and disposed of. The current waste containers have a membrane in the screw caps. These also don`t work.
Note: Until we have come up with a solution to this problem, please ensure that you do not close screw caps completely. Always remove the tamper-evident band from the screw cap.

- You must always store the waste containers in safety tubs. Do not forget: Dangerous waste containers must be stored in fume hoods or under exhaust air equipment.
- Normal waste: Never dispose of health-hazardous objects (syringe needles, toxic and contaminated waste, broken glass, sharp-edged waste) in the normal waste bin.
- Labeling of waste containers: Waterproof self-adhesive labels are available at the HCI shop. With suitable waterproof pens, you can easily write the contents of the waste containers on these labels. You can fix the label directly onto the container, followed by a transparent adhesive foil.
- Glass waste: Empty containers of hazardous substances are to be brought separately to the central disposal site. All other empty glass bottles must first be flushed with water and then disposed of in colored unsorted glass waste containers.
- Mobile solvent waste boxes (made by Renggli or MLT): These must be cleaned and maintained regularly. The front window of the MLT box is not solvent resistant; therefore cauterization damages must be prevented. It should always be covered when not in use. While pumping out the solvent waste, students must ensure that they do not spill any solvent waste from the pump tube onto the solvent waste box. Solvent waste boxes which show an internal leak must be withdrawn and reported immediately to [email protected]. Show and explain to the students the problems with the mobile solvent waste stations.

- There are many material defects with this product. These are described in the Safety Manual. To avoid accidents: Always keep a close watch on the solvent waste station and if anything is out of the ordinary, inform us immediately at our email hotline [email protected]
- Waste stations with full canisters carefully pump out their contents at the central waste disposal room. Follow the instructions of the service personnel. Note: the window is not solvent-resistant.
- Never dispose of any sharps, broken glass, silica gel powder, slag and so on in the solvent waste station. These substances destroy the suction pumps in the central disposal room.
