Classification of Lasers Question to the STAO Safety Committee

Question:

The STAO Safe on Science document (2011) indicates that only class 1 and class 2 lasers are recommended for use in high school science classes. Many of the documents that I have examined indicate that Class 3A (old classification), now called Class 3R (new classification) are also safe, unless viewed through an optical device. I respectfully request that the safety committee re-examine this issue, and include Class 3R in the recommendation.
