Laboratory Regulations

Room utilization regulations

Outside persons are only permitted to stay in the laboratory rooms when attending registered events. The staff member responsible for the event is responsible for ensuring that safety and cleanliness are maintained in accordance with the laboratory regulations. Keys may only be borrowed by staff members and students or trainees with a valid employment contract. Exceptions are to be clarified with the head of the department. In order to prevent possible theft or weather damage to the cost-intensive electronic equipment and furnishings, it is important and necessary to lock the doors and windows securely. In the interest of cleanliness and to protect the technology, do not eat or drink at the laboratory workstations. Also avoid leaving beverage bottles, dishes, leftover food, packaging material, etc. in the laboratory. Instead, please use the bins provided for waste separation.Smoking is generally prohibited in the rooms. In addition, the teaching building is equipped with smoke detectors throughout. Please do not bring bicycles or pets into the teaching building, as this is prohibited by the house rules of the BTU CS. Please take care of your personal belongings such as wardrobe, bags and other valuables yourself, as unfortunately no liability is possible in the event of loss.

Handling of electrical test setups

The modification of experimental setups of the research laboratory room 321, is reserved for the staff of the department. Infringements and resulting damages will lead to claims for damages. Inquiries in this regard should be directed to Mr. Richter.The head of the department must be notified immediately of any damage or loss of technical equipment.Laboratory modules, measuring instruments, audio and video equipment, computer equipment, accessories, etc. must be arranged clearly according to the experimental instructions and handled with care.Always use cables of appropriate length to avoid damage to sensitive measuring adapters and equipment. In addition, you must wire in such a way that your experimental setup does not pose a trip hazard or block any access points. Only switch on the power supply after you have checked that your setup is correct. Before any modification, the circuit must be de-energized. Even in the low-voltage range, electric shocks can occur with corresponding health risks. Therefore, avoid direct contact with non-insulated contact points. If necessary, the test station must be immediately disconnected from the power supply using the red emergency stop buttons located in the table superstructures. Even if electrical accidents do not primarily cause any damage to health, they must be reported.

Guidelines for computer workstations

Visual display units are to be operated in such a way that the strain on the sensory organs is minimized. This concerns the lighting conditions in the environment, the settings on the display and the distance to the user. Software that functions as smoothly as possible should also be available as far as possible. The input devices must be appropriate for the respective work requirements and ensure stress-free interaction. Harmful postures should be avoided by using suitable furniture. As a rule, the above-mentioned ergonomic aspects are taken into account at the BTU CS. However, since there may be individual deviations for each person, please make sure that you comply with the guidelines yourself and inform the responsible staff member if necessary. The passwords entrusted to you by the chair for access to the computer technology are to be treated confidentially. In general, the general guidelines of the University Computing Center apply. The installation or use of software requiring a license, which has not been purchased by the Chair of Communication Technology, is prohibited. Databases accessible to you are to be used via remote connection to the server if possible, see notes in the Wiki. Files that have been downloaded to your own computer, e.g. via ownCloud service, must be destroyed immediately after completion of the work. For this purpose, simple deletion is not sufficient. Instead, use file shredder software such as Eraser.

Other practical work

If you are working with a chip-forming machine tool (e.g. mini milling machine), the use of protective goggles is mandatory to prevent eye injuries. To avoid skin contact with the material residues, it is also recommended to wear closed clothing. If a soldering iron is used, make sure that the hot soldering tip is kept away from other objects. Otherwise, there is a risk of fire development or the creation of a short circuit. In case of burns, it is advisable to cool the affected areas immediately with running water. If you handle electrostatically sensitive components, you must protect them from unwanted charges. You can recognize such parts by the yellow warning sign on the packaging. A common measure is to apply an electrical grounding strap around the wrist. The ground strap should have ground potential.

Notes in case of fire

In case of fire of electrical equipment, please use only powder extinguishers or CO2 extinguishers. In the event of a fire, the fire department must be alerted immediately. Fire alarms are located in the hallways. There is usually also a warning signal sounding throughout the building. All persons not directly involved in rescue operations must leave the danger area immediately. Escape plans are also located in the corridors. Emergency exits are marked with green signs.Extreme caution is required in the event of smoke development. Smoke resulting from fires can spread in a very short time and have a fatal effect on the health of affected unprotected persons.

First aid

First aid boxes, as well as first aid instructions, are located in the workshop and in the corridor in the office area. Depending on the degree of injury of the casualty, it must be ensured that a doctor is called in or an emergency notification is made.For the immediate care of persons without vital signs, a defibrillator can be used. Such devices can be picked up in the laboratory hall on the first floor of the teaching building or from the security guard. The operation of a defibrillator is reserved for instructed persons.The head of the department is responsible for any accident reporting that may be required. The safety officer is also the contact person. The accident report must be submitted immediately to the BTU CS Safety Engineer. Appropriate forms are available in the central administration (see section Accident Report).
