Coding Liquids tutorial cover featuring Sagnik Bhattacharya for Lone Worker Risk Assessment for Cleaners: Early Starts and Client Sites.

Write one form per site: list each lone task and time, the hazards that come with early starts, empty buildings and keys, who could be harmed, the controls you already have, the extra action needed, and the residual risk. Walk it through with the cleaner, then have a competent person sign it off.

This is the assessment form, not the policy. The policy sets check-in rules and escalation for everyone; the form records what is true at one building and what you decided to do about it. The workplace-safety guidance I read says lone-worker risks must be covered in your general risk assessment, and that a lone worker in another organisation's premises means consulting that organisation.

Assessment, policy and site card: one job each

Cleaning firms often try to make one document do everything, and it ends up too long to read at 5.30am. Three short documents work better.

Split the round into lone situations first

Before listing any hazard, list the situations in which one cleaner is alone. Each combination of time, building and task changes the risk, so each gets its own row on the form or its own form.

SituationExampleWhy it changes the risk
Early start, before 7amAn office at 5.30am with no other staffDark arrival, nobody around, nobody to notice a fall
Late finish, after 8pmA shop or clinic cleaned in the eveningTrouble outside, tiredness, a journey home in the dark
Weekend cleanA closed building, one cleanerNo security presence, long delay before anyone misses you
Shared premisesAn office with a guard or late workersStrangers may be present, but help may be close
Occupied homeA domestic clean alone in a client's houseClient behaviour, pets, no control over who comes and goes

The hazard checklist for a cleaner working alone

The regulator's guidance names the topics an assessment should cover: violence, manual handling, medical suitability, whether the workplace presents a risk, training and experience, monitoring and supervision, and having systems to keep in touch and respond to an incident. The groups below add the cleaning detail. Each item says why it matters and how to check it, because a checklist nobody verifies is only a list.

Getting in and out

  • Entry method. Key, fob or code, and whether the door locks behind the cleaner. A door that locks behind you can leave you outside or trapped. Check by trying it with the client present.
  • Alarm entry and exit. A mistyped code at 5.30am triggers a call-out and a stressful start. Check by practising the sequence at induction and writing the delay times on the site card.
  • Fire exits. Confirm every exit can be opened from inside while the cleaner works alone. Check by walking to each one and opening it.
  • Lighting. Know where the switches are and whether lights come on automatically. Check by doing it in the dark, not at noon.
  • Lifts. A cleaner stuck in a lift with no signal has no way to call for help. Check by testing the phone inside the lift, and agree stairs if it fails.

Travel and arrival in the dark

  • The walk from car or stop to the door. Look for unlit or secluded stretches. Check by walking it at the real start time.
  • Parking. Prefer a lit space close to the entrance. Check with a photo of the spot at night.
  • Fatigue. Early starts and late finishes tire people, and the guidance notes that lone working can add to work-related stress. Check by looking at the rota for long runs of early starts followed by evening shifts.
  • The journey home. After a late clean, who knows the cleaner has left safely? The policy handles the check-in; the form notes that the journey exists.

People on and around the site

  • Who else might be present. Guards, early workers, contractors, visitors. Ask the client for regulars and their times, so an unknown person is recognisable as unknown.
  • The rule for the unexpected. If the door is already open or an unknown person is inside, the cleaner does not go in, or leaves, and calls the contact. Put it on the site card and rehearse it.
  • Aggression. The guidance lists early or late work with few people around, alcohol and drug use among clients or the public, and carrying valuables as violence risks. Check the client's incident history and your own records.
  • Accusation risk. A cleaner alone near cash, valuables or confidential papers is exposed to later claims. Agree off-limits areas and a sign-in record with the client, and discuss entrance cameras only where they are lawful and agreed.

The premises

  • Layout and floors. Stairs, wet floors, clutter, poor lighting. A fall is worse when nobody is there. Check by walking the whole route and noting the stair count.
  • Phone signal. Test every area the cleaner works in: basement, stairwell, plant room, lift. Mark dead zones on a plan.
  • Isolated or locked-off areas. Decide which are off limits when alone, and say so in writing.

The work

  • Chemicals. Prefer ready-to-use products over mixing at the site, label every container, and keep the safety data sheets where the cleaner can reach them.
  • Manual handling. Bins, vacuums on stairs, furniture. Use a trolley, set a bag-weight limit and say that heavy furniture is not moved alone.
  • Working at height. The simplest rule for a lone cleaner is no ladders; use an extension pole.
  • Electrical equipment. Check leads and plugs by eye before use, and report faults the same day.
  • Sharps, clinical waste and bodily fluids. Know the site's waste rules, provide gloves and sharps training, and never reach into a bag by hand.
  • Machines. A scrubber-dryer should be signed off per person before they use it alone.

The person

  • Experience and training. The guidance says a lone worker may need to be accompanied at first when new to a job, in training, doing a job with specific risks or dealing with new situations. A new cleaner does their first week at a site with a colleague.
  • Medical suitability. Whether a condition makes lone work riskier is a private conversation, with medical advice where needed. The form records only "suitable to work alone: yes, no or with conditions" and a review date, never the condition.
  • Language. If the cleaner's first language is not the one the card is written in, give them an emergency card they can read at speed.

Emergencies and contact

  • Raising the alarm. Which phone, who is called first and who second. Test the call from the farthest point.
  • Fire. Where the cleaner goes, what they do when the alarm sounds, and who they tell.
  • First aid. Where the kit is, and whether the cleaner has first aid training. A lone worker may need to know how to help themselves.
  • Illness or injury. How long before anyone would notice? The check-in interval in the policy answers this; the form should name it.

Key holding and alarm codes: rules the form should record

These are good-practice items, not regulator rules, but a form for a cleaning firm that skips keys is incomplete. Write the answers down for each site.

  • A key register. Who holds each key, since when, and a signature on return. Spare keys live in a locked box with an access log.
  • Tags without addresses. A key tagged with a number is a nuisance if lost; a key tagged with the address is a break-in.
  • Individual alarm codes. If the client allows, give each cleaner their own, so a log shows who entered and a leaver's code can be cancelled.
  • Codes never written down in the van. Not on the tag, not in a phone note called "codes", not on the rota.
  • A lost key. Tell the client the same day and agree whether locks or codes change. Record who decided.
  • A leaver. Keys returned and codes changed before the final pay run.
  • Arrival problems. An open door or a sounding alarm on arrival means do not enter, move somewhere safe, and call the contact.

Ask your insurer whether it attaches conditions to holding client keys and codes. If it does, the form is the place to show you meet them.

Site 4, filled in: a weak entry against a usable one

Compare two ways of recording the same hazard. A weak entry reads: "Working alone at night, risk of attack, control: be careful, risk: medium." Nobody can act on that. A usable entry reads: "Unexpected person inside at 5.30am. Control: cleaner does not enter or leaves immediately and calls the contact; site contact supplies a list of regular early arrivals. Residual: low." The difference is that the second can be checked.

The worked example below is illustrative: a two-storey office with a basement store, one cleaner alone from 5.30 to 8.00 on weekdays, a keypad alarm with a 45-second delay, a lit rear car park, an unlit side path, no phone signal in the basement and a security guard on the ground floor from 6.30.

For scoring, many small firms use a three-by-three grid: likelihood from 1 to 3 times severity from 1 to 3, with 1 or 2 as low, 3 or 4 as medium and 6 or 9 as high. The unexpected-person row might score likelihood 2, severity 3, which is 6 and high before the rule and 3 and medium after it. Treat that scale as an illustration and let your competent person set the real one.

A quick sum on time. Say the assessment takes 90 minutes per site: 30 on site with the cleaner, 30 writing it up and 30 for sign-off. For a round of 11 sites that is 16.5 hours. If an assistant cuts the writing-up half-hour to ten minutes, it saves about 3.7 hours across the round. At $30 an hour of internal time, that is a saving of roughly $110, and the walk with the cleaner, which an assistant cannot do, is where the value sits.

Scoring, sign-off and what competent means

The guidance says the level of supervision is a management decision based on the findings of the assessment: the higher the risk, the greater the supervision. It also says assessments should be reviewed periodically and after significant changes such as new staff, processes or equipment. A sign-off block that captures this has six lines.

  • Assessor and date. The person who walked the site.
  • Competent person. Someone with the training, experience and knowledge to judge the risks of this type of work. That may be a trained manager or an outside adviser, and the point is that they can say why a control is enough. If you are not sure the owner qualifies, buy an adviser's review of the first few forms.
  • The cleaner. Read, understood, comments recorded.
  • Client contact consulted. Name, date and what was agreed.
  • Review date. A fixed date as well as the triggers.
  • Triggers for an early review. New cleaner, key or code change, any incident or near miss, change of hours, change to the building, new equipment.

Write the findings down. Some places set a headcount below which writing them down is optional, but a signed form is your evidence that you looked, so keep one regardless. For more on the habit of recording events so the form improves, see fields and wording for a workplace incident report.

Ten questions to put to the client

The guidance says to consult the other employer when a lone worker is at their workplace to identify risks and controls. Send this list before the walk-through, and keep the answers with the form.

  1. Who else is in the building during our hours, and when do they arrive and leave?
  2. How is the building alarmed, and can each of our cleaners have their own code?
  3. Who holds keys, and who do we call if a key or fob is lost?
  4. Where are the fire exits and the assembly point, and are all exits usable from inside?
  5. Which areas are off limits to our staff when they are alone?
  6. Where does the phone signal fail, and is Wi-Fi calling available on your network?
  7. Is the outside route lit, and is there camera coverage of the entrance?
  8. Has there been any aggression, break-in or incident involving cleaners or contractors?
  9. Where is the first aid kit, and who is the out-of-hours contact?
  10. Are there hazards we should know about, such as plant rooms, roof access or stored chemicals?

This is also the moment to agree who pays for changes such as a motion light. Put the answer into the contract or proposal, not a hallway conversation; drafting a commercial cleaning proposal with AI shows where access and safety terms sit in a bid.

Using AI without handing it the security details

An assistant is useful for the first draft of the hazard table and for keeping the structure identical across 11 sites. It should never see your alarm codes, key locations, real addresses, floor plans, staff names or any medical detail. Call the site "Site 4" and the person "the cleaner", and read the privacy terms of any tool first; what to check in an AI tool's privacy policy sets out the questions.

Draft a lone worker risk assessment table for a commercial cleaning firm.
I will describe one site in generic terms. Do not ask for or include alarm
codes, key locations, real addresses, names or any staff medical details.
Use "Site 4" and "the cleaner".

Output a table with columns: Hazard, Who might be harmed, Existing controls,
Further action, Suggested residual risk (Low, Medium or High).

Rules:
- Cover: getting in and out, travel in the dark, people on site, the
  premises, the work, the person, emergencies and contact.
- Existing controls: use only the ones I list. Otherwise write "None stated".
- Mark every item that depends on a fact I have not given as "Check on site".
- Ratings are suggestions for a competent person to confirm.
- Do not cite laws or regulations.

Site description: [generic description]
Existing controls: [list]

Given the Site 4 description, an assistant will usually return a tidy table. It may well include the right items, and it still needs editing in four places. First, generic hazards that do not belong: a draft may list asbestos, and unless the client has told you of it, "Check on site" is the most it deserves. Second, inflated ratings: "violence: High" with no incident history should come down, because the rating belongs to the competent person. Third, invented controls: if it lists "CCTV on entrance" and you never said so, delete it. Fourth, actions you cannot take: "install CCTV" is the client's decision, so rewrite it as "ask the client".

The assistant cannot walk the building, hear the cleaner say the side path floods, or know the guard goes home early on Fridays. That is why the walk-through comes next, and why the form is not finished until the cleaner has read it.

A walk-through and a dry run before anyone works alone

  1. Walk the route with the cleaner at the real time, 30 minutes. From car to door to the farthest room, in the dark if that is when they will do it.
  2. Test the phone in every zone. Basement, stairwell, lift, plant room. Mark each dead zone on the plan.
  3. Practise the alarm. The entry sequence, twice, with the client present.
  4. Time the exit. From the farthest point to the nearest safe exit. If it is over a minute, ask whether that room needs a rule.
  5. Make a test call. The cleaner phones the contact from the farthest point and says where they are, as they would in a real emergency.
  6. Record and sign. Outcomes go on the form. The cleaner adds comments in their own words.
  7. Review after the first month. Compare the hazard table with what actually happened: near misses, odd events, anything the cleaner mentions. Add what was missing.

The policy's check-in rules, the cleaning firm's training and the cleaner's own judgement all rest on this form being accurate. The guidance warns that on-the-spot decisions, sometimes called dynamic risk assessment, are not a substitute for a proper assessment, and that workers need training to make them. A form that states the rule for the unexpected, in writing and rehearsed, is what turns a nervous judgement call into a routine. For training material that matches, a cleaning company training programme and manual drafted with AI covers building the induction.

Lone worker assessments for cleaning firms: questions answered

Do I need a separate lone worker assessment for every site?

The guidance I read says lone-worker risks must be covered in your general risk assessment, not that a separate document is required. For a cleaning round, one form per site is the practical choice, because keys, alarms, lighting and phone signal differ by building. A short site card can reuse the common parts.

Who counts as a competent person to sign it off?

Someone with the training, experience and knowledge to judge the risks of this kind of work: a trained manager, an outside health and safety adviser, or an owner who has done the training. If you are unsure, pay an adviser to review your first few forms, then reuse the approach.

Should the cleaner have a say in the assessment?

Yes. The guidance says to involve workers when considering risks and controls, and a cleaner who does the route knows where the light fails and the signal drops. Walk the route together at the real start time and record their comments on the form before it is signed.

Is a mobile phone enough as the way to call for help?

Only if it works everywhere the cleaner works. Test signal in the basement, stairwell, lift and plant room, and decide what happens if the battery dies. The guidance asks for adequate and reliable communication and a way to call for help, so test rather than assume.
