General guidelines for the use of the laboratory

  1. Knowledge of this regulation is a prerequisite for participation in the respective laboratory exercises
  2. All devices and chemicals may only be used with the express permission of the respective responsible technicians, head of department or a professionally instructed lecturer as well as scientific staff.
  3. Various test, project and exercise setups in the laboratories may not be changed or manipulated under any circumstances.
  4. There are test facilities which can only be secured to a limited extent for reasons of accessibility for measurement purposes. The training supervisor must expressly point this out and these instructions must be followed without exception.
  5. In case of alarm, fire and injuries, the supervisor and persons at risk must be informed immediately. In case of danger to persons or sounding of the alarm sirens, the laboratory/building is to be left immediately in a calm and orderly manner and waiting at the collection point for further instructions by the teaching staff of the FH. If possible without endangering yourself, the EMERGENCY OFF switch must be operated. If it is necessary to call qualified help (emergency doctor, fire department, police) immediately.
  6. The gas supply cabinets may only be opened by technicians and professionally instructed lecturers.
  7. Escape routes must always be kept clear.

Handling chemicals and gases

  1. As a general rule, chemicals and gases may only be handled where appropriate safety equipment such as extraction systems and gas warning systems are available.
  2. ALWAYS switch on the extraction system before starting to work with gases or chemicals.
  3. Wear suitable protective clothing (work coat, goggles, gloves...) when handling chemicals and when in the vicinity of persons handling chemicals.
  4. The general and special guidelines for handling hazardous substances must be observed. Before using chemicals, their hazard potential must generally be determined by studying the literature (safety data sheets, H&P phrases, disposal regulations). Substances whose harmlessness cannot be established beyond doubt must be handled in the same way as hazardous substances.
  5. The most common safety data sheets are visibly displayed in the entrance area of the respective laboratory.
  6. The labelling obligation applies to the storage of chemicals in suitable containers. It must be clear which substance is involved and who is using the substance (formula, pictogram, name, date of preparation...).
  7. All equipment used must be cleaned after use according to the instructions of the supervisor. Chemical residues must be disposed of according to the instructions of the supervisor. After use, the chemicals must be returned to the designated place.
  8. The use of chemicals requiring a toxic certificate (with a skull and crossbones pictogram) is strictly prohibited.
  9. The burn-back safety devices at the hydrogen tapping points must not be removed under any circumstances.
  10. To prevent the occurrence of explosive atmospheres, the use of chemicals is prohibited.
  11. In order to avoid the creation of explosive atmospheres, the gas concentration in the room must not exceed 10% of the lower explosion limit (LEL).

Handling electric current

  1. When working in and on electrical installations, the five safety rules apply to prevent electrical accidents. These five safety rules are applied in the stated order before work is carried out on electrical installations. After the work, they are cancelled in reverse order.
    1. Disconnect all poles and all sides.
    2. Secure against reconnection.
    3. Determine the absence of voltage at all poles.
    4. Earth and short-circuit.
    5. Cover or isolate adjacent live parts.
  2. Circuit assemblies must always be carried out in a de-energised state. Bare live parts must be assembled in such a way that accidental contact can be ruled out.
  3. Electrical circuits must not be mounted on wooden boards.
  4. Electrical assemblies with voltages > 50V DC and 25V AC may only be put into operation in the direct presence of a supervisor.
  5. Accumulators may only be charged during regular laboratory operating hours and on non-flammable surfaces. All flammable substances etc. must be removed from a sufficiently large radius. "High-power" batteries (Ni-Cd, Ni-MH, Li-Ion, Li-Fe...) may only be charged in a fire-safe metal enclosure. Make sure you choose the right charger! A personal check of the charging process approx. every 1-2 hours is required!
  6. If a person gets into the circuit or if there is a risk of this happening, immediately press the nearest emergency stop button (red mushroom button). If necessary, call qualified help (emergency doctor, fire brigade...) as soon as possible.

Accident prevention and behaviour in case of accidents

  1. Tampering with safety equipment (e.g. switching off alarm devices) is strictly forbidden.
  2. Sources of danger, damage to equipment (e.g. broken glass, spillage of chemicals, etc.) must be reported to the supervisors immediately.
  3. Wash hands after using chemicals, especially toxic ones. Pipetting by mouth is strictly prohibited. It is recommended that hands be rubbed with skin protection cream and gloves be worn before working with chemicals.
  4. Gas cylinders must be secured to prevent them from falling over.
  5. Gas cylinders may only be transported with the gas cylinder trolleys provided for this purpose. Furthermore, it must be ensured that the bottle cap is screwed on.
  6. Injuries (including minor cuts and burns) must be reported immediately to the supervisors, who will then decide on the further course of action.
  7. In the event of an accident, first aid must be given.
    • Call for help loudly, inform first aiders.
    • Call 0144 or 0112 or 001-4064343 (Poison Control Centre). Where? What? How? Who?
    • Secure the accident site, rescue the injured
    • Immediate life-saving measures
    • Further first aid
  8. In case of contact with chemicals, immediately rinse the affected area with plenty of running water that the way of the water is as short as possible (e.g. hold the affected eye downwards...). In case of fire or extensive contact with chemicals, use the emergency shower and remove contaminated clothing.
  9. When working with or in the vicinity of highly flammable or explosive substances, all sources of ignition must be eliminated. These are e.g. lighters, Bunsen burners, sparking tools (steel tools, angle grinders...), radios, mobile phones, hot plates, fan heaters and soldering irons. Static electricity, including through clothing, must be avoided.
  10. Appliances that are switched on must not be operated without a person being present. This does not apply to specially secured and labelled continuous experiments.
  11. Increased caution is required in the vicinity of rotating machine parts. Long hair, ties, etc. must be protected.
  12. The wearing of protruding jewellery is prohibited.
  13. Exercise participants must take all precautions in their own interest to reduce the risk of accidents in the laboratory.

Expectant and breastfeeding mothers must inform the respective supervisor (employment restriction!). As a general rule, expectant and nursing mothers are not allowed in the laboratory! Specific exceptions for individual exercises are possible in consultation with the head of department and the lecturers in compliance with the Maternity Protection Act.
