Industrial cleaning checklist: production floors, machines, dust and docks, by shift

Factory cleaning checklist: what to clean every shift

Every shift, the crew sweeps and spot-mops aisles and walkways, cleans up spills, empties the trash and scrap bins in its scope, wipes rails and touch points, cleans the docks, and does the break rooms, locker rooms, restrooms and offices. Machines are cleaned only when assigned, only on the outside, and only after an authorized employee has locked them out.

Plants run on shifts, so “daily” usually means one cleaning shift that overlaps the quietest production shift, or a crew on each shift for break rooms and restrooms plus a night crew for floors. The list is grouped by zone so a plant can hand each zone to a named cleaner. Walk the zone with the shift lead at the start of every shift, because what was safe to sweep yesterday may be a running line today.

Three rules apply to every line. Tape lines, guards and tags mean stop. Spills on a walkway are cleaned now, not at the end of the shift. And every exit route is walked before the crew leaves, because a mop bucket or a bagged load left in an aisle is the kind of thing an inspector photographs. For the offices and conference rooms, our office cleaning checklist has the detail.

Weekly, monthly and shutdown cleaning in a plant

Weekly work is floor scrubbing, high dusting within reach and the detail work in break rooms and restrooms. Monthly and shutdown work is overhead dust removal, floor coatings and markings, light fixtures and docks, scheduled around production because much of it needs the line below to be down and locked out.

Most plants have a planned shutdown calendar: a weekend a month, a week at year end, or a changeover between product runs. Overhead cleaning, floor recoating and anything that needs a lift belongs on that calendar, booked with the plant and listed as separate line items in the agreement. A crew that tries to do overhead work over a running line is a crew that gets sent home.

How often should each area be cleaned?

What OSHA’s housekeeping and sanitation rules require

OSHA sets a legal minimum for how clean a plant must be, and an industrial cleaning checklist should be able to show, line by line, that the plant meets it. The rules sit in four standards: walking-working surfaces, sanitation, materials storage and hazard communication.

Walking-working surfaces, 29 CFR 1910.22

Under 1910.22(a), the employer must ensure that all places of employment, passageways, storerooms, service rooms and walking-working surfaces are kept in a clean, orderly and sanitary condition; that the floor of each workroom is maintained in a clean and, to the extent feasible, dry condition, with drainage and dry standing places such as false floors, platforms and mats where wet processes are used; and that walking-working surfaces are kept free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow and ice. Those three sentences are the daily list above.

Sanitation, 29 CFR 1910.141

1910.141 says all places of employment shall be kept clean to the extent that the nature of the work allows, and that the floor of every workroom shall be maintained, so far as practicable, in a dry condition. It requires sweepings, solid or liquid wastes, refuse and garbage to be removed as often as necessary to keep the workplace sanitary, waste receptacles that can be cleaned and kept sanitary, and a continuing extermination program where rodents, insects or other vermin are detected. Food waste receptacles must be emptied not less frequently than once each working day, unless unused. That is why break rooms are on every shift’s list.

Materials storage, 29 CFR 1910.176

1910.176(c) requires storage areas kept free from accumulation of materials that constitute hazards from tripping, fire, explosion or pest harborage, and (a) requires aisles and passageways kept clear and in good repair, with no obstruction that could create a hazard. Shrink wrap, broken pallets and strapping on a warehouse floor are exactly that.

Hazard communication

Your own chemicals fall under OSHA’s Hazard Communication standard: labels, safety data sheets and training for your crew. The plant will usually give you an approved product list, because some cleaners damage floor coatings or react with process chemicals, and will expect your safety data sheets to be in the janitor closet. Rules differ by state plan, and this page is not legal advice.

Cleaning around machines: lockout and tagout awareness for the crew

A cleaning crew does not lock out machines, does not reach into them and does not clear jams. If a machine exterior is on your list, it is cleaned only after an authorized plant employee has locked it out and told you it is safe, and your cleaners are trained to recognize a lock or a tag and leave it alone.

OSHA’s standard on the control of hazardous energy, 29 CFR 1910.147, applies to servicing and maintenance of machines and equipment where the unexpected energization or start-up of the machine, or release of stored energy, could harm employees. Its definition of servicing and maintenance specifically includes lubrication, cleaning or unjamming of machines or equipment, and adjustments or tool changes, where the employee could be exposed to that energy. In other words, wiping down a press is maintenance in OSHA’s eyes, and it is covered by the plant’s energy control procedures.

The standard defines two kinds of employee a cleaning contractor needs to understand:

• An authorized employee locks out or tags out machines in order to perform servicing or maintenance, and the standard says an employee becomes one when their duties include that work. As long as your cleaners do no servicing, that is the plant’s trained person, not your cleaner.
• An affected employee operates or uses a machine that is being serviced under lockout, or works in an area where that servicing is being done. A cleaner sweeping next to a locked-out line is, at most, in that second group, and needs to know what the lock and tag mean and that only the person who put them on may remove them.

If the plant assigns your crew to wipe a machine where they could be exposed to its energy, that wipe is servicing, so each cleaner doing it must be trained as an authorized employee and protected under the plant’s procedure, for example with their own lock on a group lockout device, as 1910.147(f)(3) requires for crews. The standard also requires the plant and an outside contractor to tell each other their lockout or tagout procedures (1910.147(f)(2)).

Give the crew rules that need no judgment:

1. A machine is never “off”. It is running, or it is locked out by someone else and you have been told it is safe to wipe the outside.
2. Never open, lift or reach behind a guard, cover or door on any machine.
3. Never press a button, flip a switch, or unplug or plug in anything on the production floor to run your own equipment. Use the outlets the lead shows you.
4. Never clear a jam, pull material out of a machine, or touch a conveyor belt, even a stopped one.
5. If a lock or tag is in your way, stop and tell the lead. Never move it.
6. If a machine starts while you are near it, step back, do not try to stop it, and tell the lead.

If the plant wants your crew to do more than exteriors, for example to clean inside a hopper or under a conveyor, that work needs the plant’s written procedure, lockout by an authorized employee for every clean, and specific training. Price it separately or decline it. The plant’s EHS manager will usually respect a contractor who says no to work the crew is not trained for.

Dust, spills and floors: the hazards that are specific to a plant

Dust in a plant can be more than dirt. Many materials, from flour and sugar to wood, plastics, coal and metals, form combustible dust when finely divided, and a layer that would go unnoticed in an office can fuel a fire or an explosion if it is lifted into the air near an ignition source. Follow the plant’s dust plan, use the equipment it approves, and never blow dust off surfaces with compressed air.

OSHA’s combustible dust page treats the topic as an explosion hazard and collects the guidance, standards and enforcement that apply. For a cleaning contractor the practical points are:

• Ask what the dust is. Before you bid, ask the EHS manager whether the plant has a combustible dust hazard assessment and what it says about housekeeping, frequency and methods.
• Use the vacuum the site approves. Plants with combustible dust usually require vacuums rated for that use, not a shop vacuum from the hardware store. If the plant supplies central vacuum drops, use them.
• Lift dust gently. Vacuum first, damp-sweep where allowed, and never dry-sweep or blow dust into a cloud. Overhead surfaces are cleaned on the shutdown calendar by the method the plant sets.
• Watch the layer. Report dust building up on beams, ducts, light fixtures and the tops of enclosures, because that is where the plant’s plan will set a limit, and your report is part of how it stays under it.

Spills and leaks

Water, oil, coolant and product on a walkway are both a slip hazard under 1910.22 and, for oil and chemicals, a disposal question. The crew cleans up water and known, low-hazard spills on walkways right away with absorbent and bags the waste as the site directs. Anything unknown, anything with a strong smell, and any leak from a machine or a drum is reported, with people kept away, rather than wiped up. Keep a spill kit at the closet and know where the plant’s own kits are.

Floors

Plant floors are sealed concrete, epoxy or urethane coatings, and marked with painted or taped lines for aisles and zones. Use the floor cleaner the coating maker approves, since the wrong product dulls or lifts a coating and strips line markings. A damaged coating is reported, not scrubbed harder. Floor recoating and re-marking belong on the shutdown calendar.

Training and PPE for an industrial cleaning crew

Every cleaner on a plant account completes the plant’s contractor safety orientation before the first shift, carries the PPE the plant requires on the floor, and is trained by you on lockout awareness, hazard communication and the stop-and-report rules above. Document all of it with dates and names.

• Plant orientation: most plants require it for every contractor and will not badge a cleaner who has not done it. Budget the hours.
• PPE on the floor: commonly safety glasses, safety-toe footwear, hearing protection in noisy zones and a high-visibility vest where forklifts run, plus gloves for the chemicals you use. Your crew provides its own PPE at your cost under OSHA’s PPE rules, with the exceptions the standard lists for non-specialty safety-toe footwear and prescription eyewear.
• Forklift traffic: cleaners walk in marked pedestrian lanes, make eye contact with drivers, and never step out from behind racking. Lifts and powered sweepers are driven only by cleaners trained and authorized for them.
• Hazard communication: your product labels, safety data sheets and training, plus the plant’s briefing on the process chemicals in each zone.
• Lockout awareness: what locks and tags mean, that cleaners never remove them, and that machines are never reached into.

Keep the same cleaners on the same zones. A cleaner who knows which puddle is normal and which is new is worth more to the plant than a faster one. Our guide on how to hire cleaners covers screening, and how to start a commercial cleaning business covers the insurance, keys and hiring side of industrial accounts.

How to price an industrial cleaning account

Price a plant by zone, shift and frequency, from labor hours, with machine exteriors, overhead dust, floor coatings and shutdown work as separate line items. Square footage alone misleads on a plant because a warehouse aisle and a machining cell of the same size take very different time.

A worked example with hypothetical numbers:

• A 60,000 sq ft plant with two production zones, a warehouse, two break rooms, two locker rooms, four restrooms and 4,000 sq ft of offices, running two shifts.
• Night crew, floors and production zones: 2 cleaners for 4 hours, five nights a week: 40 hours a week.
• Day porter for break rooms, restrooms and spills during the first shift: 4 hours a day, five days: 20 hours a week.
• Total 60 hours a week, about 260 hours a month, at a loaded labor cost of $25 an hour (plant work pays more than office work, plus payroll taxes and insurance): $6,500.
• Approved products, absorbent, liners, PPE and auto-scrubber upkeep: about $550 a month. Supervision and the monthly walk: about $400.
• Overhead and margin at 25 percent on top bring the monthly price to roughly $9,300, before shutdown work.
• Shutdown items quoted separately: overhead dust removal with a lift for two cleaners over a weekend, floor recoating by the sq ft, dock pressure washing.

Build it from hours the way our commercial cleaning prices guide shows, run your own numbers in the free commercial cleaning calculator, which has an industrial and warehouse setting, and present the scope with the exclusions in the cleaning proposal template.

What a plant will require

• General liability and workers’ compensation at higher limits than an office account, often with the plant named as additional insured, and sometimes pollution liability if you handle any waste. See our cleaning business insurance guide.
• Contractor safety orientation for every cleaner, drug testing at some plants, and your safety records (training logs, safety data sheets, PPE assessment).
• A supervisor reachable during every shift, and a plan for covering absences, because a plant cannot skip a night.
• Monthly invoicing with the shutdown items shown separately, and job costing on your side so you know which zones are losing money.

Plants and the facilities companies that manage them post bids and run walkthroughs the way other commercial buyers do. Our guide on winning commercial cleaning contracts covers where to find them and how to bid.

How to check that a plant was cleaned properly

Inspect against the same zone checklist the crew uses, on a schedule, and always check walkways, break rooms and the restrooms first, because those are what the plant’s own safety committee photographs.

• Walkways and exits: dry, clear, nothing left in an aisle, wet floor signs collected.
• Dust: look along rails, enclosure tops and ledges at a low angle; a growing layer is a report, not a note.
• Break rooms and restrooms: food waste bins emptied, dispensers full, the log signed with times.
• Reports: every leak, damaged coating, missing guard and pest sign the crew saw is written down and passed to the plant, with a photo.
• The monthly walk with the facilities or EHS manager, with scope changes written into the agreement.

Photos of each zone at the end of each shift are both proof of work and the fastest way to settle a complaint about a spill that appeared after you left. Keep them with the shift log.

Is Broombook a fit for industrial cleaning companies?

No, and we make Broombook. Plant accounts need shift scheduling by site and zone, clock-in tied to the building, inspections and safety records a plant’s EHS manager can audit, and job costing by zone. Broombook is built for residential cleaning companies and small commercial recurring accounts, not for industrial janitorial contracts.

Our comparison of cleaning business software names the tools built for commercial janitorial work. If your company also cleans homes or small offices, that is where Broombook fits: online booking, recurring schedules, text and email reminders, card on file charged after the clean, and a crew link with checklists, photos and clock-in.
