Make sure that the hooks holding the hatches are secure, and do not use the hatches as a handrail. The hatches must not be left open when the telescope is being used or adjusted. Keep your hands clear of the rail when the dome-turning motor is in operation. In case of difficulty press the red button to stop the dome-turning motor. The building is fitted with automatic smoke detectors and fire alarm buttons.
Every experiment has instructions which can be found in the laboratory handbook.
Comments on safety relevant to that experiment are included in the sheet. Study the sheet carefully before beginning the experiment. No student may undertake night observation alone. There can be no exceptions to this rule. The object of the guide is to ensure the safety of all by maintaining the highest standards in relations to the Health and Safety at Work Act, 1974.
