Laser Safety

Most, if not all, Class 3R, 3B and Class 4 Lasers and Laser Systems utilize high-level AC and DC voltages in both the laser head and power supply. All Coherent laser systems are designed for operation with the laser head and power supply covers closed. Only trained personnel aware of the hazards involved should remove the protective covers.

The following precautions must be observed by everyone.

1. Disconnect main power lines before working on any electrical equipment.
2. Do not short or ground the power supply output. Protection against possible hazards requires proper ground connection.
3. Never work on electrical equipment unless there is another person nearby who is familiar with the system.
4. When possible, keep one hand away from the equipment to reduce electrical current danger.
5. Always use approved, insulated tools.
6. Be aware of any special measurement techniques required.
