For Your Protection

While safety is a top priority to ESO for workers, visitors and equipment, you may encounter potentially hazardous conditions or dangerous situations due to the operations of the observatory. Please follow these guidelines:

  • You must remain with the ESO Guide and always follow instructions
  • You must have sufficient fuel in your car to be able to drive to your next destination. There is NO gasoline station at the Observatory
  • Seat belts must be used in the vehicles
  • ESO will provide the necessary safety equipment to access the telescopes, which must be used as instructed
  • You should be aware of your surroundings while walking in the telescope area
  • Smoking is not allowed in buildings and public areas
  • For safety reasons children under 4 years are not allowed to visit the Observatory
  • For safety reasons, people with peacemaker are not allowed inside the telescopes. This is because the electromagnetic fields generated by the instrumentation may interfere with the device

The observatories are located at medium altitudes, where the lower atmospheric pressure makes less oxygen available for the body. This so-called hypobaric hypoxia may impair your physical and mental capabilities and judgement. Certain medical conditions such as cardio or respiratory diseases, hypertension, anemia, or diabetes are contraindications for the exposure to medium or high altitude. If you have or suspect to have a medical condition, it is recommended to consult your physician before travelling to the observatories. ESO has polyclinics, with a paramedic for emergency situations.

If you experience any of the below symptoms, please inform the ESO Guide immediately:

  • Acute headache
  • Dizziness
  • Nausea
  • Breathing problems
  • Ringing or blocking of ears
  • Heart pain
  • Acute muscular pain
  • Seeing "stars"

Acceptance: I have read and understand the Safety Rules and further agree to abide by all safety regulations. I understand the potential hazards and the possible harmful effects of altitude. I confirm that to the best of my knowledge I do not suffer from any illness which would render my stay in the specific conditions of the Observatory (altitude, atmospheric conditions) hazardous. I accept that ESO shall not be held responsible for any adverse effects to me resulting from my visit to the ESO observatory.

In the case of an accident or sudden illness, and if I am not able to make a decision myself, I authorize the Director of the Observatory or the delegated person to take all required emergency measures as possible after consultation with appropriate medical services.

If visiting the observatory with minors, I have explained and made sure they understand the ESO Safety Rules. I understand that I am responsible for these minors and release ESO from any and all liability during the visit to the Observatory. If you are a minor (under 18), your parents or guardian must sign this form.
