Appropriate grounding connections shall be provided for laser power supplies and other electrical components. All optical tables shall be properly grounded. To facilitate use, all grounding connections should be properly marked and all components bonded to each other so no component within the entire system can be at a charge different from ground.
8 CCR 2395, 2889
Electrical systems shall be marked to show voltage, frequency, and power output. All high-voltage sources shall be properly marked and secured to prevent accidental access.
Many laser systems use banks of high-voltage capacitors. Access to these banks shall be carefully marked and controlled, and provisions shall be made to properly maintain grounding and “bleed” charge during maintenance.
