Electrical Hazard Potential

Many lasers make use of high voltages greater than one kilovolt (kV). Pulsed lasers are especially dangerous because of the stored energy in the capacitor banks. In addition, unless properly shielded, circuit components such as electronic tubes operating at anode voltages greater than 5 kV may emit X-rays. It is important for personnel working with high voltages to be trained in the appropriate safety measures and to remain diligent in preventing potential electrical hazards, such as:

• Exposure to damaged electrical cords and cables
• Contacting an energized conductor and completing circuit

Additionally, it is critical to adhere to the OSHA Lock-out Standard, 29 CFR 1910.147, which controls the servicing and maintenance of machines and equipment in which the unexpected energization or start-up of the machines or equipment, or release of stored energy, could harm employees. This standard establishes minimum performance requirements for the control of such hazardous energy.
