Heat stress planning is becoming a year-round programme, not a summer rule
The midday break runs 15 June to 15 September, but the sites that manage it well start in spring — shade, hydration, acclimatisation and supervisor training are planned long before the ban begins.
Key takeaways
- Outdoor work in direct sunlight is prohibited daily from 12:30 to 15:00 between 15 June and 15 September.
- Employer duties cover shade, cooling, drinking water and first-aid facilities — not just the clock.
- Planning the shifted work programme in spring avoids the productivity cliff in June.
The rule itself is stable — the expectations around it are not
MOHRE's Occupational Heat Stress Prevention Policy has run for over two decades, and the timing is now predictable. What has grown is the surrounding expectation: welfare provision, awareness material in the languages the workforce actually speaks, and evidence that supervisors know what early heat illness looks like.
A workable seasonal plan
Sites that handle the season well tend to run the same sequence:
- March-April: confirm shaded rest areas, cooling and water points against headcount for peak summer.
- May: brief supervisors on recognising heat exhaustion and on the escalation route to first aid.
- June: publish the revised shift pattern before 15 June so planners, not site teams, absorb the change.
- Through the season: log rest-area checks and water availability daily — this is the evidence an inspector asks for.
Language matters more than posters
A heat-stress briefing only works if the crew understands it. Delivering the same talk in English and Arabic, and where relevant Hindi, Malayalam or Tagalog, changes comprehension far more than another poster on the hoarding.
