Identify a common misconception about Class 1 lasers.

A common misconception about Class 1 lasers is that they are entirely safe, regardless of exposure duration. While it is true that Class 1 lasers are designed to be safe under normal operating conditions, this does not mean that there are no circumstances in which they could pose a risk. For instance, if a person were to intentionally misuse or tamper with the laser system, or if the environment changed (such as if the laser were modified or if there were an optical system that could focus the beam), safety could be compromised.

It is essential to recognize that although Class 1 lasers are designed to limit output levels to prevent harm during typical use, safety guidelines and precautions should still be observed. Users should be aware of their environment and trained on the proper handling of laser equipment to mitigate any potential risks effectively. Understanding this minimizes the misconceptions surrounding laser safety and emphasizes the importance of responsibility with all types of lasers, including those categorized as Class 1.
