Case study of
#00194 Statutory heat rules for outdoor work: WBGT stop-work thresholds, midday bans and funded inspections
Implementer
Government of Spain (Royal Decree-law 4/2023), enforced through the labour inspectorate

Description
Spain adopted Royal Decree-law 4/2023 following the heatstroke death of street sweeper Jose Antonio Gonzalez in Madrid in July 2022. The decree requires outdoor work to be adapted during extreme heat episodes and allows prohibition of outdoor work during orange and red heat alerts issued by the national meteorological agency (AEMET). Enforcement relies on the labour inspectorate, which remains under-resourced for systematic inspection. Outdoor-worker heat deaths continued in subsequent seasons, indicating the legal trigger alone is insufficient without funded inspection capacity and outcome tracking.

Lessons learned
- A single well-documented worker death can move national legislation within a year, but the statute is only the first stage — replicators should plan enforcement infrastructure in parallel, not after.
- Alert-linked prohibitions (orange/red warnings) are administratively simple triggers but coarser than WBGT thresholds; they miss dangerous humid days below the alert threshold.
- Without funded inspection intensity and published outcome tracking, a legal right to stop work does not reliably stop work; deaths continued in seasons after enactment.
- The difference between Spain's partial outcome and Qatar's measurably effective regime is enforcement volume and outcome measurement, not the text of the rule.
