  1. Post warning signs in all areas where Class 3b and 4 lasers are used. Include specific information on the sign regarding the laser hazards, and otherwise comply with the ANSI Z136.1-2000 standard for these signs
  2. Consult with the LSO on selection of proper laser warning signs
  3. Display warning signs conspicuously in locations chosen to most effectively warn personnel of potential safety hazards.
  4. Do not remove laser safety signs unless authorized by the LSO or the ALU for the corresponding laser, and then only after the laser is effectively taken out of operation or enclosed so it may be classified as a class 1 laser system.
