ANNEX I
Essential health and safety requirements relating to the design and construction of machinery
The essential health and safety requirements laid down in this Annex are Manditory:

1. ESSENTIAL HEALTH AND SAFETY REQUIREMENTS
1.5. RISKS DUE TO OTHER HAZARDS
1.5.12 Laser radiation
Where laser equipment is used, the following should be taken into account:

• laser equipment on machinery must be designed and constructed in such a way as to prevent any accidental radiation,
• laser equipment on machinery must be protected in such a way that effective radiation, radiation produced by reflection or diffusion and secondary radiation do not damage health,
• optical equipment for the observation or adjustment of laser equipment on machinery must be such that no health risk is created by laser radiation.
