What is the minimum distance recommended to maintain from a laser when it is operating?

Maintaining a minimum distance of at least 3 feet from Class 3B and higher lasers is recommended due to the potential hazards associated with high-power lasers. Class 3B lasers can cause immediate eye damage and skin injuries upon direct exposure, even at distances closer than 3 feet. Keeping this distance helps to minimize the risk of accidental exposure, especially in an operational environment where the laser beam could be inadvertently directed or scattered.

Established safety protocols emphasize the importance of maintaining a safe distance to ensure effective protection measures can be implemented, including utilizing appropriate personal protective equipment and understanding beam alignment. This distance acts as a buffer zone, allowing individuals the necessary time to react in case of unexpected situations involving laser operation, further enhancing safety.
