The illumination levels should conform to those listed in Table 12.8.
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. Lower luminances may also be appropriate if computer visual display devices are employed at the LCS. For tasks like 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 followed.0700, 5680
