The Guide should remind visitors of the following Safety Rules.
Safety of those workig at CERN or visiting the laboratory is our highest priority
The experimental area does contain a number of hazards that stem from operating the detector, e.g. gas systems, high voltage lines, magnetic fields and possible low levels of residual radioactivity
The magnet is currently off and will stay so during the visit, hence there are no particular restrictions
OR
The magnet is currently on. For this reason persons with pacemakers, defibrillators, electronic medicine dispensers, hearing aids or metal implants are not allowed in the underground visit
There is no residual radioactivity in the Visit’s areas. If we would need to enter the Supervised area the levels are very low and we have dosimeters to monitor it
There are also always basic risks such as falls, trips and slips
In addition, many of the instruments, electronics, and other devices encountered in these areas are delicate and should only be handled by experts
- We therefore ask you to stay in the areas marked for visitor access and designated by your guide and not to touch any of the equipment
- Eating and drinking are strictly forbidden while underground
- Should an alarm occur please follow the instructions given by your guide who will conduct you to the surface using the lift
