12.2.5.4-1 Illumination Levels

The illumination levels should conform to those listed in Table 12.10.

Table 12.10 Range of recommended illuminances for inspection/assembly activities

Additional Information:
The values in the table are based on conservative assumptions about the reflectance of the task background, the age of the worker, and the criticality of the task being performed. Lower illuminances may be justified for more favorable visual conditions or where the need to perform critical tasks can be ruled out. For tasks similar to those performed in the control room (e.g., reading instruments, calibration, reading procedures), the lighting recommendations in Section 12.1.2.3, Illumination, should be consulted.
