Extreme Heat Watch is a planning tool for employers, school administrators, and event organizers who need to act before dangerous heat arrives — not after. It generates operational schedules adjusted for heat risk, draft risk notices for staff and attendees, and reminders tied to OSHA heat illness prevention guidelines and applicable state-level rules. The core use case is pre-event preparation: knowing which shifts need modification, which activities should be rescheduled, and what legal obligations kick in at specific temperature thresholds. It's aimed at organizations with outdoor workers, large gatherings, or vulnerable populations where heat exposure carries real liability and safety consequences.
