1.7.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health
issues. Please use the following precautions with high levels of RF power.
•
Always terminate the RF input and output connector
prior to applying prime AC input power.
•
Never look directly into the RF output waveguide
•
Maintain a suitable distance from the source of the
transmission such that the power density is below
recommended guidelines in ANSI/IEEE C95.1. The
power density specified in ANSI/IEEE C95.1-1992 is
10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
•
When a safe distance is not practical, RF shielding should be used to
achieve the recommended power density levels.
1.7.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious
safety hazards. The following precautions should be followed when there is a risk of
electrical discharge:
•
Follow all ESD guidelines
•
Remove all flammable material and solvents from the
area.
•
All probes and tools that contact the equipment
should be properly insulated to prevent electrical dis-
charge.
•
The work area should be secure and free from non-
essential items.
•
Operators should never work alone on hazardous equipment. There
should always be another person present in the same work area to assist
in the event of an emergency.
•
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
1.7.5 High Potential for Waveguide Arcing
As with all systems which utilize high power signals within
waveguide, the potential exists for an electric arc to form.
To minimize this risk, Teledyne Paradise Datacom re-
quires all waveguide be pressurized and dehydrated.
