Heat Stress & Welfare Operations
Heat management run as a controlled daily site operation, not a seasonal checklist. One place to decide what work may proceed, where, under which controls, and with which welfare evidence — from forecast and work plan through midday-break compliance to the audit pack.

Health and safety notice. This is informed operational guidance, not a medical diagnosis or a substitute for an occupational-health professional. The module supports prevention, response and evidence management. It must never diagnose a worker, determine fitness for work, or replace the approved site emergency plan and qualified medical response.
Regulatory baseline
The MoHRE rule, treated as configuration-controlled obligation
From 15 June to 15 September, work under direct sunlight and in open areas is prohibited daily from 12:30 to 15:00. Employers must provide shaded areas, suitable cooling, adequate drinking water and first-aid equipment — with hydration supplements and comfort facilities in the 2026 MoHRE announcement. The module treats these as obligations, not optional prompts, and lets emirate, free-zone, client and consultant rules make them stricter — never weaker.
Design principles
Seven rules the module never breaks
Prevention before response
Planning, welfare readiness, acclimatization, worker understanding, task controls and buddy checks come before incident capture.
Hard regulatory control
The configured restricted period creates a system stop for affected outdoor and open-place work unless a narrow, approved exception exists.
Worker-first usability
Worker screens are visual, plain-language, multilingual, mobile-first and usable offline. A signature alone is not proof of comprehension.
No clinical automation
No diagnosis, no fitness-for-work decision, no AI clearing anyone to work. Symptom data triggers the approved human first-aid and emergency workflow.
Privacy by design
Health alerts stay separate from ordinary HSE dashboards: least-privilege access, configurable retention, restricted exports and a medical-data review gate.
Evidence without bureaucracy
Project dashboard data is reused in every form. Photo, location, QR, signature or timestamp evidence is required only where it proves a critical control.
Configurable, not legally presumptive
MoHRE is the baseline; emirate, free-zone, client, consultant and project rules may be stricter. Each project has a named competent owner and a controlled rule version.
Operating surface
Nine screens, each tied to one decision
Every screen answers a question a named role has to answer that day. Project dashboard data — identity, governance, work model, welfare assets, rule set, emergency setup and privacy configuration — populates all of them, so nothing is re-keyed.
| Screen | User | Decision supported | Essential content |
|---|---|---|---|
| Today | HSE manager, site manager | Is the site ready to work safely today? | Heat status, restricted-period clock, planned work areas, welfare readiness score, unacclimatized workers, active exceptions, open CAPA, symptom alerts, overdue checks. |
| Daily Heat Plan | Supervisor, foreman | Can each crew perform its scheduled work safely? | Work area, task, exposure type, exertion level, crew, shift, shelter, buddy lead, water point, recovery plan, controls, status, approvals. |
| Welfare Readiness | Welfare coordinator, HSE officer | Are shelters and facilities genuinely usable? | Shade, cooling, seats, water, cups, ice and hydration stock, hygiene, toilets and wash facilities, first aid, access, housekeeping, photo evidence, actions. |
| Midday Break Control | Supervisor | Has affected work stopped between the configured times? | Area-by-area status, crew check-out, permitted exemption controls, photos, timestamp, sign-off, breach and stop-work action. |
| Exception / Exempt Work | Construction manager, HSE manager | Can a narrow exception be justified and controlled? | Legal category basis, why postponement is infeasible, authority permit reference, task MSRA, crew, welfare plan, supervisor, first-aid readiness, approval and closeout. |
| Worker Learning | Worker, foreman | Does the worker understand the controls and response actions? | Three-minute visual briefing, language selection, water and rest prompts, symptom cards, buddy check, short comprehension check, acknowledgement. |
| Health / Welfare Alert | First aider, emergency coordinator | What must happen now? | Red-flag prompt, location, affected worker, observed signs, site emergency-plan launch, 998 ambulance shortcut, restricted notes, closeout. |
| Acclimatization | Supervisor, HSE officer | Does a new or returning worker need staged heat exposure? | Worker cohort, start date, prior heat experience, approved schedule, supervisor checks, exception and escalation. |
| Evidence & Reports | HSE lead, client / PMC | Can the site demonstrate control without exposing private health data? | Daily plan, welfare inspections, midday register, exceptions, actions, briefing and comprehension, aggregated trends, redacted export. |
Status model
Green, Amber, Red — and what each one forces
Temperature alone never makes the decision. Forecast data is one input; the accountable supervisor weighs sunshine, humidity, air movement, exertion, PPE burden, task duration, acclimatization and the actual welfare conditions.
Green — Controlled
Trigger
Approved daily plan, welfare readiness complete, no critical exceptions, workforce briefed.
Required action
Proceed under planned controls and supervisor checks.
System behaviour
Normal reminders and routine completion checks.
Amber — Intervention required
Trigger
Welfare gap, high exposure, unacclimatized worker, incomplete plan, capacity gap, weather alert or non-severe symptom report.
Required action
Pause the affected task or area, correct and verify the control, HSE review before release.
System behaviour
Escalates to the HSE manager; the record stays open until evidence supports closure.
Red — Stop / emergency
Trigger
Restricted-period breach, missing critical welfare control, unapproved exempt work, suspected severe heat illness or emergency activation.
Required action
Stop affected work, activate the emergency procedure, secure care and access, preserve evidence, notify management.
System behaviour
Immediate multi-channel escalation, critical audit fields locked, investigation and closeout required.

Restricted-period protocol
The midday break, run to the minute
A hard warning before the stop, a stop-work prompt at 12:30, live compliance monitoring through the restriction, then a controlled restart. Sites can configure stricter rules; a less protective rule cannot be configured without approved governance.
- 11:45
“Restricted period begins in 45 minutes.”
Supervisors confirm the planned stop, shelter capacity, water and cooling readiness, and any approved exception.
Evidence: Pre-break readiness check.
- 12:15
“Prepare work areas for shutdown.”
Stop new outdoor and open-place task starts, brief crews, move tools and plant to a safe condition.
Evidence: Supervisor confirmation.
- 12:30
“Restricted period active.”
Stop affected outdoor and open-place work. Move workers to designated welfare areas unless an approved exception is active.
Evidence: Area and crew check-out, timestamp, optional QR or photo.
- 12:30–15:00
“Restricted-period compliance monitoring.”
Supervisor checks welfare conditions and, for exception work, enhanced controls at configured intervals.
Evidence: Welfare check and live exception log.
- 14:45
“Restart preparation.”
Reassess conditions, workforce readiness, water and welfare availability, and task controls before restart.
Evidence: Restart readiness confirmation.
- 15:00
“Restricted period ended.”
Resume only when the supervisor confirms conditions remain controlled and affected permits and MSRA are valid.
Evidence: Shift restart record.
Welfare readiness inspection
Shelters and facilities checked before each shift
A missing water supply, unusable shelter, failed cooling, inaccessible first aid or capacity below the assigned crew is an Amber or Red control failure depending on exposure and whether work can be reallocated. The supervisor cannot simply sign and proceed.
| Control | Pass criteria | Evidence / automatic follow-up |
|---|---|---|
| Shade / shelter | Sufficient protected seating for planned users, no direct-sun exposure, accessible from the work area. | Shelter ID, capacity, photo, map pin. Amber if capacity is below crew demand. |
| Cooling | Cooling device operating and appropriate for shelter use, with backup and escalation in place. | Asset ID, operational check, photo. Action raised if faulty. |
| Drinking water | Potable water near the work area, replenished, issued with individual cups or equivalent hygienic provision. | Stock check, water-station ID, photo, low-stock alert. |
| Hydration support | Locally approved hydration supplements available where project policy requires them. | Batch and stock field. No clinical dosage advice in the app. |
| First aid | First-aid provision accessible, complete and linked to trained responders. | First-aid point ID, kit seal check, responder name. |
| Comfort and hygiene | Toilets and wash facilities accessible, clean, stocked and usable by the workforce. | Inspection record plus cleaning or maintenance task. |
| Access and housekeeping | Safe pedestrian route, lighting where relevant, clean floors, seating, signage, waste removal. | Photo and CAPA if deficient. |
| Emergency information | Shelter displays the project emergency card and a clear route and point for ambulance access. | QR or posted-card confirmation. |


Exception / exempt work
Eight gates before restricted-period work is released
MoHRE recognises limited exemptions — technically non-deferrable asphalt or concrete work, work to contain hazards or repair faults affecting the community, and work requiring a government authority permit. The module never presents these as blanket permission.
| Gate | Mandatory requirement | System rule |
|---|---|---|
| 1. Category | Select an approved exemption category and state why postponement is not feasible. | Free text alone is not sufficient. |
| 2. Authority permit | Upload or reference the competent authority permit where the activity requires one. | Approval blocked without the required attachment or reference. |
| 3. Task risk control | Link the current MSRA, PTW, work method, location, crew, equipment and specific heat controls. | Blocked if mandatory documents are expired or unapproved. |
| 4. Welfare enhancement | Name the dedicated shaded recovery point, water and hydration support, first-aid cover, buddy lead, relief crew and supervisor. | All fields required before approval. |
| 5. People controls | Confirm each worker is briefed, acclimatization status reviewed, and able to report discomfort without penalty. | Medical conditions are never a general dashboard field. |
| 6. Approval | Construction manager and HSE manager approve; add client, consultant or authority approval where project rules require it. | Approval expires with the specific task or shift. |
| 7. Live monitoring | Supervisor logs start, interval welfare checks, any stop or restart, and crew relief. | A missed check escalates automatically. |
| 8. Closeout | Confirm work end, workforce condition check, no outstanding action, evidence completeness. | An exception can never be copied forward automatically. |
“An exemption is not a waiver of heat controls. If any required control is unavailable, conditions change, or a worker reports symptoms, stop the affected work and follow the site emergency procedure.”
Symptom alert and emergency response
Emergency and first-aid support — not a diagnosis tool
This workflow routes people to the approved site emergency plan and qualified response. It never attempts a medical determination and never clears anyone to resume work.
Urgent — suspected severe heat illness
Observations
Confusion, altered mental state, slurred speech, loss of consciousness, seizure, or a worker unable to respond normally.
Immediate site action
Stop work. Activate the site emergency response and call 998 for an ambulance. Move the worker to a shaded, cool area if safe and let trained personnel provide care under the site emergency plan. Keep access clear for responders.
System behaviour
Red alert, time-stamped emergency card, location share, emergency coordinator notified, record locked, privacy restricted.
Prompt first-aid / medical assessment
Observations
Headache, nausea, dizziness, weakness, heavy sweating, thirst, elevated temperature, reduced urine output, fainting or persistent cramps.
Immediate site action
Remove from heat, notify the supervisor and trained first aider, follow the site response plan and seek medical evaluation where required. Never send a worker back to task based on an app response.
System behaviour
Amber or Red depending on the trained responder's decision. Only the minimum necessary facts are recorded.
Early discomfort / self-report
Observations
“I feel too hot”, unusual fatigue, discomfort, or concern about a buddy.
Immediate site action
Stop or pause the affected task, provide recovery and water, supervisor check, escalate if symptoms persist or worsen.
System behaviour
Amber alert, no diagnostic label, task-recovery record.
“This may be a medical emergency. Stop work. Activate the site emergency plan. Call ambulance 998 in the UAE. Do not use this screen to diagnose the worker or decide they are fit to resume work.”
Worker briefing
Three minutes, illustrated, in the worker's language
Plain-language, spoken and illustrated content, with a visual comprehension check. A failed answer starts a re-brief with the supervisor — it is never used to blame or exclude a worker.
1. Why heat matters
“Heat can make you unwell quickly. Your safety is more important than finishing the task. Take water and recovery breaks. Tell your buddy or supervisor early if you feel unwell.”
2. Restricted-period rule
“From 15 June to 15 September, outdoor and open-place work stops from 12:30 pm to 3:00 pm unless your supervisor shows you an approved exception and extra controls.”
3. Find welfare
“Your shelter is: [shelter name / map]. Your water point is: [water point]. Your first aider is: [name / contact].”
4. Buddy check
“Check your buddy. If they look confused, faint, very weak or unwell, stop work and call the supervisor or first aider.”
5. Speak up
“You may ask for water, shade, recovery or help. You will not be punished for reporting heat discomfort.”
6. Emergency
“For a serious emergency, tell the supervisor or first aider and call the site emergency number. Ambulance in the UAE: 998.”
Acclimatization
Staged exposure as a planning process
Gradual exposure over 7–14 days for new, returning and transferred workers, offered only as editable evidence-informed defaults that the company's competent occupational-health or HSE authority approves before activation.
| Step | Module control | Guardrail |
|---|---|---|
| Identify cohort | Mark the worker as new, returning after absence, transferred, or otherwise requiring review. | Never ask for unnecessary diagnoses or medical history. |
| Apply approved schedule | Show the project-approved staged exposure plan, assigned task, supervisor and review date. | No auto-clearing; a supervisor or competent process confirms progression. |
| Enhanced supervision | Require a buddy assignment, more frequent recovery prompts and a supervisor check. | A missed check creates an Amber alert. |
| Deviation | Allow stop, slower progression, reassignment or referral under the approved site process. | No clinical detail in general workforce notes. |
| Completion | Supervisor records successful completion or handoff to the approved occupational-health process. | Completion is not a medical fitness certificate. |
Evidence and assurance
One export the client, PMC or auditor can read
Incident content is de-identified unless the recipient is authorised for restricted information, and every pack carries approvals, audit trail, issue date, author and an export hash reference.
| Evidence pack section | Included records |
|---|---|
| Planning | Seasonal plan, daily heat plans, work-area schedule, MSRA and PTW links. |
| Welfare | Welfare capacity plan, inspection records, photos, defect CAPA, water, cooling and first-aid readiness. |
| Workforce | Briefing completion, comprehension and re-briefing summary, buddy-system records, acclimatization summary. |
| Restricted period | Area and shift compliance register plus approved exception records with closeout. |
| Monitoring | Supervisory checks, weather and heat reference where enabled, leading indicators. |
| Incidents | De-identified summary only, unless the recipient is authorised for restricted information. |
| Assurance | Approvals, audit trail, report issue date, author and export hash reference. |
| Leading indicator | Target | Escalation |
|---|---|---|
| Welfare readiness completed | 100% of expected checks | A missing critical control or unchecked welfare area before work is Red. |
| Restricted-period compliance | 100% unless an approved exception exists | Any unapproved affected work during the restriction is Red and investigated. |
| Exception completeness | 100% of active exceptions hold all required approvals and controls | An incomplete or expired exception triggers stop-work. |
| Worker briefing coverage | 100% of affected assigned workers | Any unbriefed worker is re-briefed before affected work. |
| Critical CAPA closure | 100% by due date unless formally extended with risk control | An overdue critical welfare CAPA is Red. |
| Record integrity | 100% of audit sample has timestamps, signer, location and evidence | A suspected false or backdated entry triggers investigation. |
| Reporting culture | Reviewed in context — more early discomfort reports can mean better reporting | A low report count alone is never scored as positive. |
Delivery
Acceptance criteria, rollout stages and explicit non-goals
MVP acceptance criteria
| Requirement | Acceptance test |
|---|---|
| Hard stop | A supervisor cannot release configured outdoor or open-place work in the restricted period without a valid approved exception. |
| Welfare evidence | A daily plan cannot reach Green if a required shelter, cooling, water or first-aid control is missing or capacity is insufficient. |
| Escalation | A Red symptom or emergency alert shows site emergency contacts and 998, sends the configured alert, and limits access to authorised roles. |
| Privacy | A client or PMC user cannot view worker health-alert detail but can view a redacted compliance summary. |
| Traceability | Every approval, edit, check, action, export and escalation carries user, timestamp and immutable audit history. |
| Worker usability | A worker can complete the visual briefing, identify the welfare location and answer a comprehension prompt on mobile in an available language. |
Recommended rollout
| Stage | Duration | Success condition |
|---|---|---|
| Design validation | 2 weeks | Approved rule set, form wording, privacy model and emergency flow. |
| Pilot configuration | 2 weeks | Daily plans, readiness checks and restricted-period controls used consistently. |
| Operational pilot | 4 weeks | 95%+ expected plan and check completion, all critical welfare gaps actioned, no privacy breach. |
| Improvement and scale | 2–4 weeks | Permissioned case study and a rollout decision. |
Deliberately out of scope for the first release
These need a formal privacy impact assessment, occupational-health design review, legal review and customer consultation before they are even considered:
- Automated medical diagnosis
- Automated fitness-for-work decisions
- Individual heat-risk scoring built on health data
- Disciplinary scoring from symptom reports
- Mandatory worker wearable or camera surveillance
