Protecting an elderly or dependent relative in an emergency

Two official schemes exist so that an elderly or dependent parent gets identified and contacted as a priority, even if you don't live nearby. Here's how to activate them.

In brief

Two free steps protect an elderly or dependent relative: registering them on the municipal registry of vulnerable people (town hall or CCAS, article L121-6-1 of the Code de l'action sociale et des familles), which triggers a priority contact during a heatwave or exceptional event; and, if they depend on medical equipment, having them registered as a high-vital-risk patient with the ARS, to be notified by Enedis before a scheduled power outage. A child or caregiver can carry out these steps on their behalf.

The municipal registry of vulnerable people

Every French municipality keeps a nominal registry of vulnerable people, provided for by article L121-6-1 of the Code de l'action sociale et des familles and detailed by decree n°2004-926 of September 1, 2004. It allows municipal services or the CCAS (municipal social action centre) to quickly contact registered people when a heatwave plan or another exceptional event is triggered.

QuestionAnswer
Who can register?People aged 65 and over living at home, people 60 and over recognised as unfit for work, and adults with disabilities.
Who applies?The person themselves, or a third party: child, caregiver, neighbour, doctor.
How?Town hall or CCAS, by phone, mail, online or in person. Free of charge.
What it triggersContact from municipal services as soon as the alert plan is activated, to check in or offer help.

If your relative lives in a different town from you, registration is done with their town hall, not yours.

The high-vital-risk patient (Enedis)

If your relative depends on an electric medical device, a second scheme exists. The high-vital-risk patient (PHRV) status is aimed, according to Enedis, at people on a ventilator with a battery autonomy of 4 hours or less per day, and children on home parenteral nutrition.

To obtain it, you must register with the regional health agency (ARS) of your department; the request is renewable every year. Once registered, for a scheduled outage (works), Enedis notifies individually by mail five days in advance, with the expected date and time. This scheme doesn't cover accidental outages, which by nature remain unpredictable.

What this status doesn't do: it doesn't provide a generator or backup battery. For a relative at very high vital risk, arranging an independent power solution with the medical team remains essential.

The medication reserve

Beyond the two official schemes, a few simple checks reduce the risk of an outage or a few days of isolation:

Helping from a distance

When you don't live nearby, registering on the two official registries remains the foundation: they're what triggers a local contact in an event. On top of that, a simple network helps bridge the hours before an official service steps in:

The official registries above remain the foundation: they trigger a local response. On top of that, if your relative installs the app themselves, LASTLINE can help you:

This assumes your relative installs and uses the app themselves: LASTLINE doesn't monitor anyone without their knowledge.

Frequently asked questions

How do I register a parent on the municipal registry of vulnerable people?

By contacting the town hall or CCAS (municipal social action centre) where your relative lives, by phone, mail, online or in person. Registration is free and can be done by a third party (child, caregiver, doctor) if the person can't do it themselves.

Who can register on the municipal registry?

People aged 65 and over living at home, people aged 60 and over recognised as unfit for work, and adults with disabilities, under article L121-6-1 of the Code de l'action sociale et des familles.

What is a high-vital-risk patient?

An Enedis status for people on a ventilator with 4 hours or less of battery autonomy per day, or children on home parenteral nutrition. Registration is done through the regional health agency (ARS), and renews every year.

Is a high-vital-risk patient notified before a power outage?

For a scheduled outage (works), Enedis notifies individually by mail five days in advance, with the expected date and time. This scheme doesn't cover unplanned, accidental outages.
