Abstract

This document provides radiation safety requirements (normative) and guidelines (informative) for the consideration of faults for Class 1 laser devices with laser radiation directed towards the eyes or face. Requirements for the safety of the nominal emission are not in the scope of this document.Examples:devices with laser light facial or ocular recognition;virtual reality headsets or glasses;devices with gesture tracking via eye or facial movements;driver surveillance cameras;full body scanners (including eyes, face, and body).Products exempted from this document include:medical and ophthalmic devices;automotive (lidars), lamps;laser applications where the laser is used in a professional (non-consumer) setting and is intended for direct or long-time exposure of the eyes or face.This document provides normative requirements and informative guidelines for:radiation safety analysis;production-line testing;hazard analysis for laser radiation emissions (using a modified safety-focused FMEA approach)all subsequent references to FMEA in this document refers to this safety-focused FMEA approach.examples of typical failure modes and mitigation techniques
