  • Page 6 MECHANICAL SAFETY Good mechanical safety practices are more important than ever now that microprocessors are taking control of mechanical devices. Yet, the area of mechanical safety is often overlooked during instrument servicing. We may be able to change this situation if you heed the following safety tips: Remember to keep clothing and fingers away from rotating or moving components.
  • Page 7 ELECTRICAL SAFETY It is shocking but true. Many people service instruments without giving much thought to electrical safety. Unfortunately, this can be a dangerous mistake. It pays to take a few precautions before and during servicing to avoid injury from electrical shock.
  • Page 8 ELECTROSTATIC DISCHARGE Static electricity is an electrical charge which can damage circuitry and components. Listed below are important Electrostatic Discharge guidelines for handling electronic components. Following these guidelines will avoid needless damage to circuit cards and components on them. • Keep paper, non-conductive plastic, plastic foams or cardboard away from circuit boards and components and static-free work areas.
  • Page 9 HIGH VOLTAGE REMINDER When you have removed the front panel and/or the rear panel from the instrument and have the circuit breaker on, there is high voltage (>200VAC/ 300VDC) on some components. This voltage is there even though the instrument is not running.
  • Page 10 REFRIGERATION SYSTEM SAFETY Working with refrigeration systems requires special equipment and training. If you are not familiar with the operational theory for refrigeration systems and the special requirements for performing service on a system, do NOT attempt it. Use the following precautions for working with refrigeration systems in Beckman instruments.
  • Page 11 BRAZING SAFETY PRECAUTIONS Brazing requires the use of a high-temperature "MAPP Gas" torch and as such many potential safety hazards exist. Always follow the guidelines below when brazing. 1. Wear safety glasses. 2. Work in a ventilated area. 3. Know fire extinguisher location. 4.
