3.General rules for workshops in SCool LAB 3.1Capacity Groups of 36 participants maximum are accepted, accompanied by at least one official S'Cool LAB tutor. The recommended number of participants is 24. 3.3Safety instructions All (safety) instructions shall be presented clearly by the tutors and followed strictly by all participants and all tutors.

Slide 6

3.4General 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 shall be used for breaks. Cameras are of course highly welcome!

3.5Restriction for minors and pregnant women due to ionising radiation SCool 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 participants 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. All participants in general are not allowed to handle radioactive sources directly, this will be done by the tutor. To prove, that are no dangerous dose rates from ionising radiation, active dosimeter will be used to monitor the exposure. For details about radiation protection measures in SCool LAB, please refer to EDMS 1448213

3.6Bags To avoid accidents, all bags and jackets shall be stored inside the indicated shelf or at the wardrobe in the corridor.

Slide 9

3.6Microphones To make sure everybody can understand the instructions, tutors need to keep in mind that the room is really big and it is therefore recommended to use a microphone. 3.7Tidiness To facilitate cleaning, chairs must be put on tables after the workshop.
