29 CFR 1910.141: OSHA Sanitation Standard

Regulatory citation: 29 CFR 1910.141, Sanitation (General Environmental Controls, Subpart J)

What Is the OSHA Sanitation Standard?

Section 1910.141 sets basic hygiene requirements for permanent places of employment in general industry. It covers housekeeping, waste disposal, vermin control, drinking water, toilets, washing facilities, showers, change rooms, clothes drying and the handling of food and drink at work.

Why Sanitation Matters

Lack of clean water, toilets or washing facilities can cause illness and spread contamination. OSHA has also noted that delayed toilet access can lead to health problems such as urinary tract infections.

Core Obligations

1. Keep Workplaces Clean, Dry and Free of Vermin (1910.141(a)(3)–(5))

Places of employment must be kept clean to the extent the work allows. Workroom floors must be kept dry as far as practicable. Where wet processes are used, drainage must be maintained and dry standing places such as platforms or mats provided where practicable, or suitable waterproof footwear supplied. Receptacles for putrescible waste must not leak, must be easy to clean and must have a solid tight-fitting cover unless they can be kept sanitary without one. Waste must be removed as often as needed to keep the workplace sanitary. Enclosed workplaces must be built and maintained, as far as reasonably practicable, to keep out rodents, insects and other vermin, and a continuing extermination program must start once vermin are detected.

2. Provide Potable Water (1910.141(b)(1))

Potable water must be provided in all places of employment for drinking, washing, cooking, washing food and utensils, and personal service rooms. Portable drinking water dispensers must be sanitary, capable of being closed and fitted with a tap. Open containers such as barrels or pails that water must be dipped or poured from are not allowed, and neither are common drinking cups.

3. Mark Nonpotable Water (1910.141(b)(2))

Outlets for nonpotable water, such as water for industrial or firefighting use, must be posted or marked to show the water is unsafe and not to be used for drinking, washing, cooking, washing food or utensils, or washing clothes.

4. Provide Enough Toilets (1910.141(c)(1)(i) and Table J-1)

Toilet facilities must be provided in toilet rooms separate for each sex. Separate rooms are not needed where a room is used by one person at a time, can be locked from the inside and has at least one water closet. Table J-1 sets the minimum number of water closets: 1 for 1 to 15 employees, 2 for 16 to 35, 3 for 36 to 55, 4 for 56 to 80, 5 for 81 to 110, 6 for 111 to 150, and 1 more for each additional 40 employees over 150. Where toilets will not be used by women, urinals may replace some water closets, but water closets may not drop below two-thirds of the minimum. Each water closet must be in its own compartment with a door and walls or partitions high enough to give privacy.

5. Allow Timely Toilet Access (1910.141(c)(1))

OSHA interprets the duty to provide toilets as a duty to make them available. Employees must be able to use them when they need to, and restrictions must be reasonable and must not cause extended delays. The toilet count rules do not apply to mobile crews or normally unattended work locations, as long as employees have transportation immediately available to nearby toilets that meet the standard.

6. Provide Washing Facilities and Showers (1910.141(d))

Lavatories must be made available in all places of employment, with hot and cold running water or tepid running water, hand soap or a similar cleansing agent, and individual hand towels, air blowers or clean sections of continuous toweling. Where another standard requires showers, the employer must provide one shower for each 10 employees of each sex, or fraction of 10, who must shower during the same shift.

7. Provide Change Rooms Where Required (1910.141(e) and (f))

Where a particular standard requires employees to wear protective clothing because of possible contamination with toxic materials, change rooms with separate storage for street clothes and protective clothing must be provided. Work clothes provided by the employer that become wet or are washed between shifts must be dry before reuse.

8. Control Food and Drink (1910.141(g) and (h))

No employee may eat or drink in a toilet room or in any area exposed to a toxic material, and food may not be stored in those places. Waste food receptacles must be emptied at least once each working day unless unused. Any employee food service must follow sound hygienic principles.

Common Compliance Approaches

Check Headcount Against Table J-1

Recalculate toilet numbers against Table J-1 whenever headcount grows, and check each sex's facilities separately where separate rooms are used.

Write a Clear Restroom Access Policy

Where line work needs cover, use relief workers in enough numbers that nobody waits an unreasonable time.

Example: Sanitation in Practice

A food packaging plant grows from 140 to 190 employees on its day shift. Using Table J-1, the safety manager works out that 150 employees need 6 water closets and the extra 40 need 1 more, so 7 are now required. The plant adds a single-occupancy lockable restroom, labels a washdown hose outlet as nonpotable water, and replaces a shared drinking cup at a water jug with a closed dispenser with a tap and disposable cups. Supervisors are briefed that relief cover must be arranged quickly when an operator asks to leave the line.

Note: Section 1910.141 applies to permanent places of employment in general industry. Construction sanitation is covered separately in 29 CFR 1926.51. State plan states may set stricter rules.

Frequently Asked Questions

Can a single-occupancy restroom be shared by men and women?

Yes. Separate rooms for each sex are not required where the room is occupied by no more than one person at a time, can be locked from the inside and contains at least one water closet.

Can an employer limit when workers use the restroom?

Only within reason. OSHA expects timely access, and restrictions must not cause extended delays. Relief or signal systems are acceptable if there are enough relief workers.

Do field crews need toilets at every job location?

Not under the Table J-1 count. Mobile crews and normally unattended locations are covered if employees have transportation immediately available to nearby toilets that meet the standard.
