Extreme heat pages start with indoor temperature, cooling access, and who has the least margin. A fan, open window, or short break can be useful in mild heat, but it is not the same as a safer cooling plan when alerts, vulnerable people, or symptoms are present.
Extreme Heat
Use this section when heat changes the plan before anyone feels ready to stop. Start with cooling access, indoor temperature, vulnerable people, pets, medicine storage, outdoor work, and travel timing, then choose the page that matches the first bottleneck. Severe symptoms, inability to cool down, or official heat instructions belong ahead of any checklist.

Start with the link that matches the real bottleneck: an alert, a route, a supply, a person with less margin, or a stop point.

Field notes
Use these to narrow the first page to open.
- Move the person, pet, medicine bag, or work plan out of peak heat before symptoms decide the timeline.
- Check cooling access: air-conditioned room, public cooling location, shaded route, water, and a person who can check back.
- Separate optional activity from essential travel or work so the nonessential part can stop first.
- Waiting until the room feels unbearable before choosing a cooler place.
- Using a fan as the whole plan when alerts, vulnerable people, or medication storage are involved.
- Packing water but forgetting the stop point for outdoor work, exercise, pets, or children.

Decision map
Use the map before opening another checklist.
Is indoor heat, outdoor work, or vulnerable-person risk rising today?
Check local heat alerts and pick the cooler-place option before symptoms start.
Can the person cool down reliably without a fan-only plan?
Use shade, air-conditioned space, water access, and earlier check-ins for children, pets, and older adults.
Are confusion, fainting, severe weakness, vomiting, or inability to cool down present?
Stop planning and use emergency help instead of another checklist.

Start with cooling access and the hottest part of the plan. Check indoor temperature, shade, water access, travel time, medicine storage, pets, and people who may not cool down easily. Do not use a fan, a bottle of water, or a short break as proof that heat risk is controlled. Use the sections on the heat map, before heat peaks, during the heat to compare the first check with the stop point. Use emergency help or local authorities when symptoms, unsafe indoor heat, official warnings, or inability to cool down change the situation.
