Safety Rules for Visiting Astronomers at the 30m telescope 1. To offer you a safe travel and stay at the observatory there is a safety responsible and the operators with rules on how to proceed. You have to follow their instructions. If you have any questions or suggestions your comments are very welcome. Please contact the operator or any IRAM staff member at any time if you need any help or advice. 2. There is a floor plan of the observatory in the short corridor between the garage and the living quarters. In this map you can see how the different observatory areas are organised. It is also indicated the different evacuation ways for the case of an emergency. Please dedicate some time to familiarize yourself with this map. 3. The operator on duty has the primary responsibility for the safety of the persons at the site and for the telescope installations. Under all conditions and in any case the operator on duty decides when observations are possible, when to move and when to stow the telescope. 4. In case of a fire emergency or other general emergency the safety responsible and/or the operator will decide how to proceed. Their instructions must be followed. 5. In case of bad weather conditions, mainly due to fog or wind, the operator on duty has rules to decide if the transport between Granada and the observatory in any direction is possible or not. The decision to postpone the transport is not subject to discussion. 6. Visitors access and staying is confined into the living building (three floors with the control room, offices, library, dormitories, dining room etc.). Access to the interior of the telescope tower (cable spiral, servos room, receiver cabin etc.) is possible, but the operator on duty must be informed and his authorisation is necessary. The operator must be informed again after the visit to the telescope tower is finished. 7. Smoking is not permitted in the IRAM buildings. 8. Do not drink the tap water at the observatory (no risk in Granada). There is bottled water available in the kitchen. 9. Any excursion in the surroundings of the observatory is at the visitor's own risk. In any case, visitors must return before nightfall. Excursions after nightfall are forbidden. If you leave the observatory, it is mandatory to tell the operator where you go and for how long you will be away. You must follow his decision whether or not it is safe to teave the observatory and follow his recommendations. Take a portable radio with you. Remember that you are at a high mountain site, where weather conditions can change quickly. Especially in winter, leaving the observatory can be very dangerous. Please, if you leave the telescope, always leave the door closed to avoid animals entering the observatory. 10. If you walk close to the observatory in winter consider that very often there is very slippery ice on the ground. Wear a protective helmet. After a bad weather period pieces of ice falling from the telescope are a frequent danger. 11. If you feel bad, sick or have some medical conditions don't hesitate to inform the safety responsible or the operator. They could get you in contact with a doctor at any time. There is medication and first aid equipment at the observatory and the staff is instructed on its use. There are also medical instructions in several languages.
