Illumination (general industry) - Michigan

Michigan has adopted many federal OSHA standards and incorporates them by reference. The Michigan Occupational Safety and Health Administration (MIOSHA) plan has an illumination regulation for the sawmill industry:

1. A minimum of 30 foot-candle intensity lighting must be maintained at the operator’s workstation, and at the point of operation of a debarker, head saw, or trim saw.
2. Work areas under mills, and log dumps, booms, ponds, or storage areas used at night must have lighting facilities in accordance with ANSI A11.1 “Industrial Lighting” (1965), as adopted in R. 408.15209.
3. Employers must ensure that illumination is provided and designed to supply adequate general and local lighting to rooms, buildings, and work areas when in use.
4. Employers must ensure the adequacy and effectiveness of illumination, determined by whether:
   1. The quantity of light in foot-candle intensity is sufficient for the work being done;
   2. The quality of the light is free from glare and has correct direction, diffusion, and distribution;
   3. Shadows and extreme contrasts are avoided or kept to a minimum.
5. Stairways should be adequately lighted per the rules listed here.
6. Fuel houses, bunkers, hoppers, and bins must have adequate exits and lighting.
