What is the recommended condition for a person standing within the NOHD* when a laser device is fired?

The recommended condition for a person standing within the Nominal Ocular Hazard Distance (NOHD) when a laser device is fired is that they can be unprotected without injuries. The NOHD is the distance from a laser source within which the eye may be exposed to hazardous levels of laser radiation. When someone is within this distance, it is understood that protective measures, such as wearing goggles, are necessary to prevent eye injury if exposed to the laser beam.

In this context, wearing protective goggles would be advisable for safety, as indicated by industry standards and protocols. However, the assertion that individuals can be unprotected without injuries challenges the validity of these standards since exposure to laser radiation in the NOHD poses a risk of harm to the eyes. Using a laser rangefinder is also a tool that can assist in measuring distances rather than ensuring safety from laser exposure and does not address the safety conditions within the NOHD. Remaining behind a backstop does not relate to the recommended conditions surrounding laser safety, as backstops are typically used in firearms safety contexts rather than addressing the risks associated with lasers.

Therefore, the accepted protocol when dealing with laser devices emphasizes the requirement for protective eyewear for individuals within the NOHD to ensure safety from potential exposure and injuries
