Case study of
#00194 Statutory heat rules for outdoor work: WBGT stop-work thresholds, midday bans and funded inspections
Implementer
Qatar Ministry of Labour, with the International Labour Organization; thresholds informed by FAME Lab field research
Timeline
Since May 1, 2021

Description
Qatar's 2021 Ministerial Decision, developed with the ILO after FAME Lab field research on worker heat strain, created a national outdoor-work heat regime combining a clock-hour ban (10:00–15:30, June 1–September 15) with a year-round WBGT stop-work threshold of 32.1 °C. Employers are required to conduct heat risk assessments. Enforcement is substantive: in a single June, authorities carried out 4,400 inspections and closed 269 sites. Recorded occupational heat-stress injuries fell from 1,372 in 2019 to 351 in 2022. The reform followed mass migrant-worker deaths and international scrutiny around the FIFA World Cup; recorded-injury counts also depend on reporting practices as well as true incidence.

Lessons learned
- Pairing a physiological WBGT threshold (32.1 °C) with a simple clock-hour ban is operationally effective: the threshold catches dangerous humid days that a time ban alone misses, while the time ban is easy to verify on any site.
- Enforcement volume is what distinguishes this regime: 4,400 inspections and 269 site closures in one month made the rules real on sites — replicators should budget for equivalent inspection capacity.
- Grounding thresholds in local field physiology research (FAME Lab) gave the standard scientific legitimacy with employers and regulators, suggesting that country-specific heat-strain data strengthens adoption.
- The reform was driven by mass migrant-worker deaths and World Cup scrutiny; replicators should not assume that level of external pressure, and should treat recorded-injury reductions with caution given potential reporting-practice changes.
