Four facts behind Poland’s new stop-work line
The regulation turns workplace temperature into a sequence of duties. The operational challenge is proving when each threshold was crossed and what changed next.
- The rules enter into force on 11 January 2027Poland published the amendment on 10 July 2026 and gave employers six months to prepare.
- Protection starts before work must stopTechnical or organisational measures begin above 25°C or 28°C, depending on location and physical workload.
- The hard ceilings are 32°C and 35°CHeavy outdoor work cannot continue above 32°C; indoor work cannot continue above 35°C when atmospheric heat causes the exceedance.
- A forecast is a warning, not the legal recordEmployers need a defensible measurement point, time, workload classification and documented response at the actual workplace.
Poland has done something unusually concrete with extreme heat. From January 2027, temperature will no longer be only a weather condition that employers are expected to manage in general terms. It will become an operational boundary that activates different duties and, at two upper limits, stops work.
The numbers are easy to repeat. The harder question is how a warehouse, construction site, workshop or delivery operation turns them into a reliable decision. A phone forecast cannot classify physical effort, locate the hottest workstation or prove how long a threshold lasted. The regulation therefore creates a measurement problem as much as a labour-law rule.
The climate signal
Hot days are no longer exceptional planning events
IMGW data for 1991–2025 show hot days and tropical nights occurring in recent years with increasing regularity. In Wrocław, 2015 brought 37 hot days—roughly three times the 1991–2020 norm cited by the institute.
The legal response
The law converts exposure into a duty ladder
Instead of waiting for a universal definition of an unbearable day, the amendment ties action to the measured workplace, the place of work and the amount of physical effort required during the shift.
The four numbers do not mean the same thing
At 25°C, the first distinction is workload and location. Heavy indoor work crosses into the protective-duty zone, as does work performed outdoors. For heavy indoor work, the employer must use suitable technical measures to reduce or limit the rise in temperature where possible, or organisational measures tailored to the work. Outdoor work requires organisational measures that minimise the effect on health.
At 28°C, other indoor work enters the same protective zone. That does not automatically close an office or production hall. It requires the employer to respond with measures appropriate to the conditions—ventilation, shielding, changed hours, additional breaks, job rotation or another solution developed for the workplace rather than copied from a generic summer memo.
The 32°C limit is narrower. It applies to outdoor work involving physical effort above the energy-expenditure thresholds written into the regulation: more than 1,500 kcal during a shift for men and 1,000 kcal for women. When atmospheric conditions push the temperature above that point, the work cannot be performed. At 35°C, the corresponding stop-work line applies indoors.
This is why a single poster saying “work stops above 32°C” would be wrong. A courier carrying parcels, a road crew using heavy tools and a person monitoring a gate may all be outdoors, but the regulation does not assign them the same upper ceiling. The task, its energy demand and the measured location have to remain attached to the temperature.
A weather app cannot decide whether the line was crossed
A forecast is useful because it tells managers when to prepare shade, ventilation, staffing changes and a measurement schedule. It is not a substitute for conditions at the workstation. Sun, roofing, machinery, air movement, reflective surfaces and the urban heat island can make a site materially hotter or cooler than the nearest official observation.
Forecast
Prepare the control plan
Use the warning to schedule measurements, cooling, breaks, shade, staffing and an escalation owner before the shift begins.
Workplace record
Decide the duty at the point of exposure
Record where and when the reading was taken, what job was being performed, which threshold applied, what control changed and who authorised continuation or suspension.
The regulation does not prescribe one thermometer, logging interval or sensor height. That flexibility makes a written protocol more important, not less. A defensible system should identify representative hot spots, avoid measurements that are conveniently distant from the work and create a repeatable route for escalating readings.
The same logic already appears elsewhere in Polish planning. Our analysis of Poland’s commuting class showed how national growth figures can conceal the actual burden at the point where a person experiences the system. Heat regulation makes that gap literal: the national forecast is context, but the workstation is where the duty attaches.
The Heat Duty Relay is the real operating system
A good protocol should not end with a number in a spreadsheet. It needs a handoff from measurement to control, from control to a continuation decision, and from suspension to a documented restart. That sequence is the article’s signature module because it turns this specific regulation into an auditable workplace rhythm.
Signature module · The Heat Duty Relay
Keep the reading attached to the decision it triggers
Each handoff preserves the place, task and responsible person so that a threshold cannot disappear between the thermometer and the shift plan.
01 · LocateMeasure the exposure pointName the workstation, surface conditions, time and active task.
02 · ClassifyAttach the correct thresholdIndoor or outdoor, ordinary or heavy work, and the applicable energy demand.
03 · ActProtect or suspendActivate the agreed control or stop the affected work when the upper line is exceeded.
04 · ReleaseProve the restart conditionRe-measure, record the changed conditions and identify who returned the task to service.
The weak link is an unowned handoff. A reading without a named decision-maker creates delay; a suspension without a restart criterion creates pressure to improvise.
Employers do not invent the organisational measures alone. The regulation requires consultation through the workplace health and safety commission. Where no such commission exists, the employer follows the Labour Code consultation route and seeks the opinion of the physician providing preventive occupational healthcare. Employees must then be informed of the agreed arrangements through the channel used at that workplace.
Exceptions change the legal route, not the physics
The amendment carves specified work and services out of the paragraph that sets the maximum temperatures. It also names employees in childcare institutions, uniformed services and soldiers. The exact scope matters because emergency response, essential services and continuous operations cannot always use the same stop mechanism as an ordinary warehouse.
Ordinary route
The threshold changes what work may continue
Measure, classify the task, apply agreed controls and suspend work when atmospheric heat exceeds the relevant upper limit.
Specified exception
Continuity needs a separate safety design
Exclusion from the maximum-temperature paragraph is not proof that exposure is harmless. Sector duties, risk assessment and workable heat controls still need competent legal and occupational-health review.
Do not reduce compliance to buying a thermometerThe legal risk sits in the chain: an unrepresentative location, the wrong workload class, a control that was never consulted, or a restart that cannot be explained after an incident.
The six-month lead time is short enough to matter. Employers that wait for the first 2027 heat warning will have to choose sensors, classify jobs, consult measures and train supervisors at once. The stronger approach is to use the remaining months to test the relay on a warm but non-critical day and find where information stops moving.
The broader lesson resembles the mismatch in Poland’s housing system: formal supply does not guarantee usable access. A thermometer supplies a number. Only the organisational chain makes that number usable for protection.
Questions about Poland’s workplace heat limits
When do Poland’s new workplace temperature rules start?
They enter into force on 11 January 2027, six months after publication of the amendment in the Journal of Laws on 10 July 2026.
Does every workplace close at 32°C?
No. The 32°C upper limit concerns heavy outdoor work above the energy-expenditure threshold in the regulation. The general indoor upper limit is 35°C. Lower thresholds activate protective measures rather than automatic closure.
Can an employer use the temperature from a weather app?
A forecast can trigger preparation, but it may not represent the actual workstation. Employers need a measurement protocol that reflects where exposure occurs and records the job and applicable threshold.
Who chooses the organisational measures?
The employer establishes them after consultation through the health and safety commission. If there is no commission, the Labour Code consultation route applies and the preventive occupational-health physician gives an opinion.
