Electrical Hazard Potential

Many lasers make use of high voltages (>1 kV), and 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. For this reason, all health care laser systems should be installed and operated in conformity with the National Electrical Code (NFPA 70-2008), the Standard for Health Care Facilities (NFPA 99-2005), OSHA, The Joint Commission (TJC), and all applicable state laws.

It is important for personnel working with high voltages to be trained in the appropriate safety measures and to remain diligent in preventing any of the following potential electrical hazards:

• Damaged electrical cords and cables
• Inadequately grounded HCLSs
• Use of conductive liquids
• Non-adherence to the OSHA Lock-out Standard (29 CFR 1910.147)
• Equipment not returned to its original operating condition following maintenance
• Workers contacting an energized conductor and completing circuit
• Lack of demonstrated electrical safety programs
