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:
l. Remember to keep clothing and fingers away from rotating or moving components.
It is easy to slip, lose a tie, or get cut while working near one of these devices.
2. Unless it is absolutely essential, never run mechanical components without the
protective guards in place.
3. Always use the tools specifically recommended for the job. This not only reduces
the chances of injury, it minimizes damage to the instrument.
4. Although not always possible, it is recommended that mechanical devices be
adjusted or calibrated with the power turned OFF. This is especially important if
you are working with a microprocessor-controlled instrument, which can start
running without notice or user intervention.
5. After the mechanical repairs have been completed, always check that all mounting
hardware and safety shields are in place and secure. By doing so, you will not only
ensure safe operation of the instrument, but may reduce callbacks.
As you can appreciate, all it takes is good common sense, plus good safety techniques
that are basic and easy to remember. With this is mind, you should have no trouble
servicing mechanical devices safely.

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. Here are a few safety tips that can help
keep you on the job without a sudden vacation:
l. Avoid standing on damp floors! People have been shocked simply by standing on a
wet floor and then working on live equipment.
2. Be sure to disconnect the power cord before working on any high voltage circuitry!
As power switches disappear from new equipment, this precaution is very easy to
overlook. Attach probes for checking voltage and current with power off!
3. Read and heed ALL caution labels! They are posted for YOUR safety.
4. Take care of test equipment. Be sure to use the right probes for the right job.
Measuring high voltages, for example, requires a well-insulated, high voltage probe.
Damaged probes and cables are dangerous and should not be used. Also, be cautious
around test equipment such as an oscilloscope. The oscilloscope case may become
live if you connect the cable ground to a live circuit. Avoid this dangerous situation
at all times!
5. Always treat cathode ray tubes (CRTs) and uncased photomultiplier tubes (PMTs)
with special care. When carrying them, wear eyeglasses and protective gloves. If
these devices are dropped or struck with a sharp object, they can implode violently
and scatter glass.
These basic tips regarding good electrical safety practices are easy to remember.
Combined with good common sense, they should keep you on the job for a long time to
come.

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.
•Keep hand creams and food away from the conductive work surfaces. If spilled on the
bench top, these materials contaminate and increase the resistivity of the work area.
•Be especially careful when using soldering guns around conductive work surfaces.
Solder spills and heat from the gun may melt and damage the conductive mat.
•Check the grounding connections on wrist strap and static mats. (Mat must have proper
ground.) Make certain they fit snugly before starting work with the components and
printed circuit cards.
•Touch the conductive work surfaces before starting work.
•Know the ESD caution symbols.
•Do not allow anyone not grounded to touch ESD sensitive components in the work area.
To be grounded, they must be standing on the conductive floor mat and must touch the
conductive bench top mat before touching the components or printed circuit cards.
•Do not place ESD-sensitive components on work areas that are not grounded properly.
•Do not touch the component by the pins or leads since the most damage is done at these
points by ESD. Handle the components by the cap edges or body and the printed circuit
cards by the edges.
•Do not handle components or printed circuit cards during transport between work
stations. Components or cards must not be directly handled by anyone not grounded.
•Do not use Refrigerant or other chlorinated cleaners at the work area. Use conductive or
anti-static bags and containers for storage and transportation of components or circuit
boards.

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.

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.
1. Always use protective glasses and clothing.
2. Do NOT inhale refrigerant. It has an intoxicating effect and is harmful to your health.
3. Refrigerant can easily cause "frostbite". Be especially careful with liquid refrigerant.
4. Use caution when replacing a burnt out compressor. The oil in the compressor may
be very caustic or acidic. Use protective gloves.
5. Charge refrigeration systems with gas from the low side only. High side charging
may damage the compressor.
6. Do NOT run a compressor without refrigerant in the system. Compressors are cooled
by the refrigerant and will burn out if there is no cooling.

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. Heat sink, shield components.
5. All refrigerant removed from the system (no pressure).
6. Do not invert turbo-torch (flame-thrower).
7. Fit and brace parts.
8. Check to see if smoke detectors are present--move your operation.
9. Always insure that heated parts have cooled completely before handling them.
