Lasers and X-Ray Equipment

DOE-HDBK-1092-98

2. The heating coil should have its cold (outside) lead properly grounded.

3. A coaxial cable of correct impedance and adequate construction may be desirable to deliver

the RF power to the coil in order to prevent the leakage of the RF energy in the laboratory.

10.10.4.3 OPERATION AND MAINTENANCE

1. Shielding must be maintained to minimize RFMW radiation.

2. Wearing metallic objects when operating or maintaining the induction heating system is

prohibited.

3. Posting suitable warnings to indicate equipment hazards.

10.10.5 LASERS AND X-RAY EQUIPMENT

This section is applicable to laser systems and x-ray equipment used in research. Both fixed and

portable equipment are covered regardless of input voltage. Only electrical hazards are addressed in

this subsection. Refer to ANSI Z136.1 for laser hazards and 29 CFR 1910.306 (f) for x-ray hazards.

10.10.5.1 HAZARDS

1. Dangerous voltages are present inside the equipment.

2. Implosion hazards may exist with the covers removed.

3. Energy storage devices may present a hazard due to a residual charge even when the system

is de-energized

4. Dangerous voltages can exist across the impedance of the grounding conductor during

operation.

5. Failure of interlocks and safety devices may allow access to energized parts.
