The nature and degree of hazards posed by optical radiation exposure in the workplace depend foremost on the spectral distribution of the radiation, which is a function of the radiation source(s) present. It is, therefore, sensible to approach occupational exposures by type of source, or by type of process that uses optical radiation sources. Quantitative assessment of optical radiation hazards can be difficult, requiring specialized instrumentation and complex mathematical manipulations. In practice, the industrial hygienist in the workplace must often rely upon guidelines developed by standards‐setting bodies or recommendations from manufacturers that specify control measures based on easily accessible information about the source and the exposure conditions (62). In this section, optical radiation hazards and recommended controls are discussed for specific processes and sources.
