The heat warning worked. Did the government?

If a government warns a worker about dangerous heat, but the worker has no power to stop working, what has the warning achieved?

The information arrived. The worker’s choices may be exactly the same.

This is where I want the conversation about heat preparedness to begin. With the person who receives the warning and still needs someone else to act.

During my time leading statewide public-service reform in Quintana Roo, Mexico, implementation meant working through the distance between an authorised decision and a service someone could actually use. That is the question I now bring to my research on heat governance: when risk changes, what changes for the people depending on public protection?

A cooling centre can be listed on a map and closed when someone needs it. An advisory can recommend breaks while the decision to allow them rests with an employer. An agency can fulfil its reporting obligations while the next action remains someone else’s responsibility.

At each of these points, I would ask: who can change the situation, and what requires them to do so?

Who acts when the person at risk cannot?

Telling someone to stay cool assumes they have somewhere cool to go. Telling them to avoid outdoor work assumes they control their working day.

Before issuing that advice, authorities should identify what prevents people from following it. Then assign responsibility for addressing those barriers: transport to an accessible cooling space, longer opening hours, outreach to people living alone or workplace protections that can be enforced.

The test is straightforward: can this person realistically do what we are asking? If the answer is no, the response needs another step.

Does the person responsible have the power to deliver?

I would ask every agency leading a heat response to choose one promised action and trace it through to delivery.

Who approves the additional hours? Who pays the staff? Who confirms that the doors opened? If a contractor does not deliver, who can intervene that day?

A name beside a task is a start. That person also needs authority, resources and an agreed route for resolving problems beyond their control. These arrangements should be settled before the heat arrives.

Who checks what is happening on the ground?

For cooling facilities, publish operating hours and when they were last verified. Make it possible to report a closed door or inaccessible service by phone and in person. Assign someone to respond while the information still matters.

An outdated record should be marked “unverified” and checked. We should be willing to show what we do not know.

Otherwise, the resident standing outside a closed facility knows something the government’s dashboard does not.

What happens when protection does not arrive?

This is the question I would put to the official signing off on preparedness.

For each critical service, establish a deadline and a specific escalation procedure. If a facility cannot open, who arranges an alternative? If outreach cannot reach someone, who follows up? If demand exceeds capacity, who can release additional resources?

Record how long correction takes and whether the people affected receive the service. Use that record to change the next staffing plan and budget.

A recurring problem should come back as a management decision.

What would justify saying that people were protected?

In my research, I use “protective adequacy” to ask whether the protection people can actually use matches the risk they face.

That requires following the response beyond its announcement. Was the service delivered? Could the intended population use it? Is there evidence that exposure or health risk declined?

An observational evaluation of Ahmedabad’s heat action plan examined mortality and found reductions after implementation, particularly at higher temperatures. It could not isolate the effect of each measure, but it asked whether a health outcome changed.
