Controlled Access

Persons unnecessary to a laser's operation should not be allowed access to the laser equipment control area. Anyone who enters a laser area with unenclosed Class 3B or Class 4 beam paths should first be given appropriate eye protection and required safety training.

Prominent and correct signage is very important as an initial warning in case of accidental entry into a controlled area. The entrance to the laser system area (usually at the door) must utilize flashing red lights during operation of all Class 3B and Class 4 lasers to prevent a worker from accidentally walking into the area during operation of the equipment.
