What OSHA and the research say about your plant's break room, restrooms and entry.

The break room, the restrooms and the entry tile everyone crosses coming in off the floor all fall under OSHA's sanitation standard.

NIOSH has gone into working plants and wiped those surfaces. A few studies have also measured what a dirty office costs the people who work in it.

What OSHA already requires

The first line of OSHA's sanitation standard, 29 CFR 1910.141, applies to the whole building: "All places of employment shall be kept clean to the extent that the nature of the work allows."

Washing facilities "shall be maintained in a sanitary condition." Soap is required. Food waste containers are emptied at least once each working day, and no one eats or stores food in a toilet room.

Floors and hallways fall under a second standard, 1910.22. They must be kept "in a clean, orderly, and sanitary condition," dry where that's feasible, and leaks or spills can't be left standing. That covers the entry and the hall to the break room.

The duty falls on the employer. Hiring a cleaning crew for the office side is one way a plant meets it.

Plants that use lead, cadmium or chrome

Stricter rules apply here, and they call out the places people eat. A plating shop working with hexavalent chromium has to keep eating and drinking areas "as free as practicable of chromium (VI)." At cadmium plants, eating tables stay clear of cadmium.

Lead plants must keep all surfaces "as free as practicable of accumulations of lead," and workers can't go into the lunchroom in clothes still carrying lead dust.

Those same standards restrict how the dust gets cleaned up, and compressed air is one method they rule out. That cleanup is part of your plant's hygiene program. During the walkthrough we ask how you handle it and build the office scope around it.

How floor dust reaches the break room

NIOSH wiped surfaces outside production at an electronics recycler in 2018. Lead turned up on a break room refrigerator handle, the floor of the break area, the soda machine and an office desk. The fridge handle was worst. NIOSH's advice to the company was to clean its non-production and break areas more often.

Cafeteria tabletops at a battery plant NIOSH visited came back clean. Workers still carried lead in on their hands, and that's the job the restroom soap and sinks are there for.

In 1995 NIOSH reported to Congress on about 65 cases of lead poisoning in workers' families, 35 of them in the United States, caused by dust carried home on clothes, skin and hair.

Slips begin at the entry

According to the Bureau of Labor Statistics, falls, slips and trips caused 479,480 injuries in 2023 and 2024 that kept private-sector workers off the job, for a median of 13 days away.

One NIOSH team tracked slips at three hospitals for ten years, and liquid on the floor caused the most claims, 24 percent. Slip claims dropped 58 percent after a program that included clean, dry floors and walk-off mats, though those were hospitals and the study had no comparison group.

In a plant, the entry floor and the hallway to the break room are the same floor.

Clean offices and the people who work in them

Danish researchers in 1999 put an old, soiled carpet behind a screen in an office, out of sight, and measured how the staff worked. Typing output fell about 6.5 percent. It recovered once the carpet came out.

A Dutch team in 2018 measured surface dirt and dust across five offices and surveyed the people working there. Staff in the cleaner offices rated themselves happier and more productive, but that's a self-rating, and the authors warn against stretching it.

Bradley, a Menomonee Falls company that sells restroom fixtures, surveyed office workers in 2021. Three in four said the state of a workplace restroom shows how much a company values its workforce.

Our part and yours

Our work is the office side of the plant, meaning front offices, break rooms, restrooms and locker room restrooms, conference rooms and the entry, cleaned one to five nights a week, with a photo report sent to your inbox after every shift.

Your plant crew and specialty vendors handle the production floor, the machines, process waste and any regulated dust cleanup. You'll find programs, prices and the plant areas we cover on our industrial cleaning page.

This is a plain-language summary. Anyone with a legal question should go to the full text of the standards, linked below.

Questions plant managers ask

Does OSHA require plants to keep break rooms and restrooms clean?

Yes. Under OSHA's sanitation standard, 29 CFR 1910.141, all places of employment shall be kept clean to the extent that the nature of the work allows, washing facilities must be kept sanitary, and food waste containers have to be emptied at least once each working day. Plants that work with lead, cadmium or hexavalent chromium have extra rules on top of that for the areas where people eat.

Does OSHA say how often a break room has to be cleaned?

Only for food waste, which has to go out at least once each working day. Everything else is a condition, clean and sanitary. OSHA leaves the schedule to the plant. CDC guidance says to clean high-touch surfaces regularly, and more often where traffic is heavy.

Do you clean production areas or regulated dust?

No. Our work covers the office side of the plant: offices, break rooms, restrooms, locker room restrooms and entries. Production areas, and any cleanup under OSHA's lead, cadmium or chromium rules, stay with your plant crew and specialty vendors.
