Class 1 lasers require which of the following warnings or requirements?

Class 1 lasers are categorized as lasers that are safe under all conditions of normal use. They are designed in such a way that they do not emit hazardous levels of radiation, making exposure to the human eye or skin unlikely and non-damaging during typical usage. Because of this intrinsic safety, there is no requirement for specific warnings or signs, as users are not at risk from these types of lasers when used properly.

This classification contributes to the understanding that Class 1 lasers are inherently safe, minimizing the need for any additional safety measures commonly required for higher class lasers that pose greater risks. In contrast, higher class lasers may necessitate various warning signs or restricted access protocols to ensure safe usage and limit exposure to potential hazards.
