What is the risk of operating a laser without a safety interlock?

Operating a laser without a safety interlock significantly increases the risk of unauthorized access and accidental exposure to the laser beam. Safety interlocks are engineered to prevent the operation of the laser if safety measures, such as doors being closed or protective barriers being in place, are not met. By lacking this vital safety mechanism, there is a higher chance that personnel could inadvertently gain access to a potentially hazardous area where the laser is active, leading to serious injuries from unintended exposure to the laser beam.

This not only endangers operators but can also put bystanders at risk. Therefore, ensuring a safety interlock is in place is crucial for maintaining a safe work environment when using lasers. Other options, while they may relate to laser functionality, do not address the immediate and safety-critical concern of exposure and access.
