2 S’Cool LAB bookings
2.1 S’Cool LAB Schedule
All S’Cool LAB Workshops are managed by the S'Cool LAB team ([email protected])
based on fixed time slots (see table 1). All workshops are registered in the CERN Visit
Agenda: https://publicoutreach.cern.ch.
Table 1. S’Cool LAB Workshop Schedule
2.2 Allowance for S’Cool LAB tutors
The same rules as for official CERN guides apply.
1509171

3 General rules for workshops in S’Cool LAB
3.1 Capacity
Groups of 36 participants maximum are accepted, when accompanied by official S'Cool
LAB tutors. The recommended number of participants is 24.
3.2 Number of tutors – number of participants
The number of tutors depends on the number of participants and the activity:
For Cloud Chamber Workshops one tutor can lead a workshop for up to 24 participants,
since there are no major hazards associated with the equipment and only little guidance
of the participants is needed. In addition, all participants conduct the same experiment
at the same time which makes supervision manageable by one tutor. Groups of students
will always be accompanied by at least one additional adult, in most cases the teachers
of the students, who will be able to supervise the group if necessary. As an exception,
bigger groups (max. 36p) can be accepted if a second tutor is present.
For other experiments, e.g. X-Ray units, one tutor will guide maximum 12 participants,
since more guidance of the participants is needed.
3.3 Safety instructions
At the beginning of a workshop, tutors present the (safety) instructions in an
understable way to the participants. During the workshop tutors ensure that everyone
(also the tutors) follows them strictly.
3.4 General laboratory rules
S'Cool LAB is a laboratory, therefore it is strictly forbidden to eat, drink or smoke
inside the lab. The corridor in front of the lab (143-R-203) or the Microcosm garden
shall be used for breaks. Cameras are of course highly welcome.
1509171

3.5 Restriction for minors and pregnant women due to ionising
radiation
Although there are radioactive preparations held in a specific safe when not in use
S’Cool LAB is not a supervised radiation area. Therefore, there is no general restriction
for pregnant women and minors. Specific rules apply for certain experiments and
participant groups:
-
Pregnant tutors are not allowed to supervise experiments which include
radioactive preparations or X-Rays.
Pregnant participants are not allowed to participate in experiments that
work with radioactive preparations.
Participants in general are not allowed to handle radioactive sources
directly. This is done by the tutor.
To prove that there are no dangerous dose rates from ionising radiation, active
dosimeter can be used to monitor the exposure. For details about radiation protection
measures in S’Cool LAB, please refer to “EDMS 1448213 v.1 "Safety file S'Cool Lab" by
J. Woithe, S. Schmeling”.
3.6 Bags
To avoid accidents, all bags and jackets are stored on the indicated shelves or at the
wardrobe in the corridor (Figure 2).
Figure 2 - Map of S'Cool LAB, shelf for bags and wardrobe marked
3.7 Microphones
To ensure thateverybody can understand the instructions, tutors should keep in mind
the acoustics of the room. It is therefore recommended to use a microphone. There are
two handheld and two xxxable, belt-mounted Madonna mics.
3.8 Tidiness
To facilitate cleaning, chairs must be put on tables after the workshop. Tutors must
remind the participants to clean their shoes if they enter from the outside, and to leave
the room tidy.

5 Emergency situations
5.1 General Information
S'Cool LAB tutors represent CERN to visitors, therefore their behaviour must always be
responsible, thoughtful and safe. They follow the instructions of the workshop manual,
report anomalies to the S'Cool LAB team ([email protected]) and always put the safety
of the participants first.
All tutors must know the following:
 Where are the emergency exits?
 Where is the assembly point?
 Where is the first aid box including eye wash bottles?
 Where is the emergency stop to cut the electrical power?
 Where is the fire extinguisher?
 Where is the IP phone and which number do I call in case of an emergency?

LAB
5.3 Experimental hazards
Each S’Cool LAB experiment has associated hazards e.g.:
-
Electricity
Chemicals
Cryogenics
Lasers
-
Radioactive preparations
X-Rays
Evacuated glass tubes
…
Tutors must be aware of all hazards and need to know, what to do in case of an
emergency. Before starting the experiments, tutors need to instruct the participants
regarding the hazards. During the workshop, they supervise the participants and make
sure that they follow the instructions.
During the training session tutors learn about these hazards. A summary safety form
for every experiment is distributed in the training and can also be found online (Tutor
SharePoint http://cern.ch/scoollab-inside).

In addition, more information on chemical safety, radioactive preparations and XRay units3 in S’Cool LAB can be found in EDMS 1509160 upon request and in a printed
version on-site.
5.4 What to do in case of an emergency?
In the event of an emergency your priority is the safety of your participants. You
should not attempt to manage any dangerous situation such as a fire but IMMEDIATELY
move the participants to a safe area.
If someone is feeling unwell:
- Call the fire brigade 74444 from any CERN phone or +41 22 767 4444 using
your portable phone. Program this number into your phone’s memory in advance!
- If possible, move out of the area to fresh air.
- If the person is too unwell to move, make him/her comfortable. Talk calmly to
the person and put your hand on his/her shoulder or hold the person’s hand.
- Sit the person down (do not wait for them to faint!) and if they faint, lay them
down.
- Collect jackets to keep the victim warm, protect him/her from cold floor, and use
jackets as pillow.
- Keep people at a reasonable distance so as to avoid overcrowding the victim.
- If a situation could affect the whole group (large spills of liquid nitrogen, damaged
mercury lamps, strange smell, etc) move the entire group out of the affected
area to fresh air.
It is highly recommended that all tutors follow the CERN first aid course. This
course (free of charge) will enable you to act in a reasoned way in the event of an
incident.
5.5 Alarms
S'Cool LAB is equipped with an evacuation alarm. In case you hear the alarm:
- Immediately leave the area, checking that you have your entire group with you.
- Put on the “Emergency Guide” vest (Figure 8) to increase your visibility.
- Guide the group to the assembly point and wait there.
- You must not leave the assembly point until you have been authorised to do so
by the fire brigade. Make sure no participants leave either.
