TABLE H-120.1. — MINIMUM ILLUMINATION INTENSITIES IN FOOT-CANDLES
|Foot-candles||Area or operations|
|General site areas.|
|Excavation and waste areas, accessways, active storage areas, loading platforms, refueling, and field maintenance areas.|
|Indoors: warehouses, corridors, hallways, and exitways.|
|Tunnels, shafts, and general underground work areas; (Exception: minimum of 10 foot-candles is required at tunnel and shaft heading during drilling, mucking, and scaling. Mine Safety and Health Administration approved cap lights shall be acceptable for use in the tunnel heading.|
|General shops (e.g., mechanical and electrical equipment rooms, active storerooms, barracks or living quarters, locker or dressing rooms, dining areas, and indoor toilets and workrooms.|
|First aid stations, infirmaries, and offices.|
Sanitation Standards at Temporary Workplaces
The first set of requirements deal with potable, i.e., drinkable water, including:

|One toilet seat and 1 urinal per 50 employees.|
Under temporary field conditions, provisions must be made to assure not less than one toilet facility is available.
Hazardous waste sites that don’t have a sanitary sewer, must have the following toilet facilities unless banned by local codes:
Exception: The above requirements for sanitation facilities don’t apply to mobile crews that have transportation readily available to nearby toilet facilities.
Doors entering toilet facilities must have entrance locks controlled from inside the facility.
Other Sanitation Requirements
All food service facilities and operations for employees must meet the applicable laws, ordinances and regulations of the places they’re located.
Temporary sleeping quarters, if provided, must be heated, ventilated and lit.
The employer must provide adequate washing facilities for employees engaged in operations where hazardous substances may be harmful to employees. Such facilities must be:
Hazardous waste clean-up or removal operations requiring 6 or more months to complete must have on-site showers and change rooms for all employees exposed to hazardous substances and health hazards involved in hazardous waste clean-up or removal operations.
Showers must meet the requirements of the Sanitation standard for general industry, 29 CFR 1910.141(d)(3).
Change rooms must also meet the requirements for change rooms under the Sanitation standard, 29 CFR 1910.141(e).and consist of two separate change areas separated by the shower area. One change area, with an exit leading off the worksite, should provide employees with a clean area where they can remove, store and put on street clothing. The second area, with an exit to the worksite, should provide employees with an area where they can put on, remove and store work clothing and personal protective equipment.
Showers and change rooms must be located in areas where exposures are below the permissible exposure limits and published exposure levels. If this can’t be accomplished, a ventilation system must be provided to supply air that’s below the permissible exposure limits and published exposure levels.
Last but not least, employers must ensure that employees shower at the end of their work shift and when leaving the hazardous waste site.
