Laser Safety
Warning Signs and Labels
All laser equipment must be labeled indicating hazard classification, output power/energy, and lasing
material or wavelength with words and symbols as indicated below:
Class 4 laser equipment: DANGER, Laser Radiation (or laser symbol) - Avoid Eye or Skin Exposure to
Direct or Scattered Radiation
Labels and warning signs should be displayed conspicuously in areas where they would best serve to
warn individuals of potential safety hazards. Normally, signs are posted at entryways to laser
controlled areas and labels are affixed to the laser in a conspicuous location.
