If you use laser equipment, make sure it is designed, made and installed so accidental irradiation won’t occur.

Never expose anyone to direct radiation, radiation produced by reflection or diffusion, or secondary radiation. Everyone using the equipment must be properly trained.

Ensure that any visual equipment used to observe or adjust the laser equipment is safe to use and does not create a risk to health and safety from the laser’s rays.

Don’t use Class 3B or Class 4 lasers in construction work.
