Maharashtra's state heat wave action plan, issued in Marathi by the Disaster Management Department under the Disaster Management Act 2005 framework. Public-health alert overlay only: the plan states on printed page 34 that its instructions are advisory in nature ('सदर सूचना या मार्गदर्शक स्वरूपाच्या असून'), and it publishes no WBGT value, no wet-bulb value and no work/rest schedule. Read in full from the primary Marathi PDF on 2026-07-31; see docs/research/maharashtra_hap-2026-07-31.md for every threshold with its Marathi quote, translation and page citation.

Only plainsHeatWaveAbsoluteThresholdC (45C) and plainsSevereAbsoluteThresholdC (47C) drive the alert level. The terrain thresholds (40/37/30C, printed pages 9 and 25) and the departure-from-normal criterion (4.5-6.4C / >6.4C, printed page 10) are published criteria carried for traceability but not computed -- no region-type or seasonal-normal input exists. advisoryMiddayAvoid 12:00-15:00 (printed pages 35, 36 and 71) is citizen-facing public-health advice, never composite-entering. flexibleHoursAgeThresholdYears (printed page 29) is not computed -- no worker-age input. The plan's separate 14:00-16:00 window concerns permits for marches and demonstrations, not work, and is intentionally absent from this table.
Programmable logic: Classify maxTempC against the IMD plains absolute-temperature criterion and surface the plan's advisory controls (avoid outdoor exertion 12:00-15:00, cool drinking water at the workplace, ORS, shaded rest, extra care for pregnant and sick workers, shift work to early morning) as informational output. Excluded from the work/rest composite: this is an alert_overlay, so it can never set work/rest minutes or trigger a stop-work verdict. The terrain-specific heat-wave-prone thresholds (plains >=40C, coastal >=37C, hills >=30C) and the departure-from-normal criterion (4.5-6.4C heat wave / >6.4C severe) are published by the plan and carried as named constants but are NOT evaluated -- this calculator has no region-type input and no seasonal-normal baseline-temperature input. The plan's over-50 flexible-hours provision is likewise carried as a named constant but not evaluated (no worker-age input). The plan's 14:00-16:00 window is deliberately NOT encoded: it governs permission for marches and demonstrations, not work.
