A warning sign does not separate pedestrians from a moving machine or wet strip. Define a protected route and crossings, then verify floor condition before reopening each segment.
This reference material was written and revised with AI. It has not been verified or approved by a professional. Review by a suitably qualified professional and required site approval are necessary before field use.
Stop before proceeding
Stop for uncontrolled pedestrian entry, poor braking, leakage, abnormal brush motion, uncertain floor or slope compatibility, or failed recovery. Protect the wet area and do not reopen until the floor is safe.
1. Legal and technical scope
Routine general-industry cleaning uses applicable 1910.22 walking-surface and 1910.1200 hazard-communication requirements. Covered servicing requires applicable 1910.147 energy control. Construction cleaning must be assessed under the applicable Part 1926 provisions. The Tennant T360 manual is a specific technical example; use the actual model instructions for floor, chemical, slope, pad and isolation limits.
Confirm whether federal OSHA or an OSHA-approved State Plan covers this employer and worksite; state requirements and public-sector coverage can differ. Apply the task-specific provisions and limitations identified above.
| Basis | Application |
|---|---|
| OSHA 29 CFR 1910.22 | Keep walking surfaces safe; guard unsafe areas until corrected. |
| OSHA 29 CFR 1910.1200 | Chemical labels, safety data sheets and worker information. |
| OSHA 29 CFR 1910.147 | Covered general-industry servicing and stored energy. |

4. Fictional scenario and failure mechanisms
Retained AI-generated educational illustration from the source edition; not a real incident photograph, approved installation drawing or evidence of equipment suitability.
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Item | Fictional scenario |
|---|---|
| Initial | A lobby is being scrubbed before a busy arrival period. |
| Change | A stripe of water remains behind the machine. |
| Failure | The operator repeats the pass while pedestrians enter. |
| Outcome | The recovery fault leaves a slip hazard despite visible warning signs. |
| Barrier | Close the affected route, recover the water, correct the fault and verify a safe floor before reopening. |
Why the controls matter
A warning sign does not separate pedestrians from a moving machine or wet strip. Define a protected route and crossings, then verify floor condition before reopening each segment.
Repeated passes cannot fix failed liquid recovery. Stop and protect a residual-water area, identify squeegee, vacuum, tank or hose faults and retest in a segregated area before continuing.
Key-off does not establish safe brush access. Isolate battery, charger and other relevant energy by the actual servicing procedure before clearing or maintenance. Wastewater goes to the approved route for its contents, not the nearest drain.
Decision sequence
| Step | Decision |
|---|---|
| Known | A stripe of water remains behind the machine. |
| Unknown | Actual condition, extent of damage and suitability of people and doors, travel clearance remain to be established. |
| Hold | The operator repeats the pass while pedestrians enter. |
| Evidence | Link people and doors, travel clearance, recovered floor, speed and handling, waste and cleaner, approved outlet to the affected equipment or work area. |
| Next | Close the affected route, recover the water, correct the fault and verify a safe floor before reopening. |
5. Conditional decisions and common errors
| Condition | Action | Evidence | Proceed when |
|---|---|---|---|
| Pedestrians enter | Stop and separate | Route and crossings | Area controlled |
| Water remains | Hold cleaning and access | Recovery-system check | Safe floor verified |
| Brush obstructed | Isolate before access | Battery and stored energy | Safe clearing method |
| Waste route unclear | Retain wastewater | Contents and disposal route | Route authorized |
Similar appearance, different evidence
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Comparison | Supported decision | Insufficient basis |
|---|---|---|
| Condition | Route and crossings | Pedestrians enter has not been resolved. |
| Evidence | Battery and stored energy | A photograph or a completed-looking task without the relevant inspection record. |
| Release | Route authorized | Completion of one step does not release the excluded tasks in section 2. |
6. Roles and responsibilities
| Role | Responsibility |
|---|---|
| Work supervisor | Assign the task boundary, stop authority, interfaces and emergency communication for battery walk-behind floor scrubber. |
| Technical lead | Confirm Floor and route; Traffic timing; Slope and surface; Exit access. Resolve design and manufacturer limits before work. |
| Authorized crew | Apply Product identity; Dilution and PPE; Fill level; Floor and pad match. Stop when the working arrangement changes. |
| Inspector / receiving lead | Review People and doors; Travel clearance; Recovered floor; Speed and handling. Transfer Parking and power; Floor release; Fault and receiver; Key custody. |
Role labels allocate responsibilities; they do not confer a legal qualification. Verify the competence, training and authority required for the actual task.

Stop work
Stop for uncontrolled pedestrian entry, poor braking, leakage, abnormal brush motion, uncertain floor or slope compatibility, or failed recovery. Protect the wet area and do not reopen until the floor is safe.
Emergency response
Stop the machine safely and protect people from traffic and wet flooring. For serious injury call 911 and follow site first aid. Isolate the affected area after a chemical spill; use the SDS and trained response procedure rather than collecting an unknown spill with the scrubber.
