Immediate response

What to do in the event of an alert or major danger?

The course of action always depends on the official message. Read the alert completely, do not approach the dangerous area and apply the instructions received — shelter, evacuation or other measure — until the end of the alert.

1

Read and locate

Identify the authority, the risk, the area concerned and the time of the message.

2

Get to safety

Follow the sheltering or evacuation instructions precisely, without improvising.

3

Stay informed

Consult FR-Alert, the prefecture, town hall, radio or emergency services depending on the situation.

References checked with the official presentation of FR-Alert. In case of immediate danger: 15, 18 or 112.

Daily preparation

Start simply, then improve your preparation

It is not necessary to buy everything at once or transform your home. Serious preparation starts with a few easy-to-implement decisions, then improves over time based on household, territory and budget.

Take stock of what you already have

Most homes already have some of the necessities: bottles of water, simple foods, a lamp, usual medications, chargers, warm clothing and copies of documents. Gathering them mentally or on a short list allows you to identify the real gaps without giving in to an impulsive purchase.

Take advantage of this first inventory to check the dates, the condition of the batteries and the accessibility of the equipment. A lamp stored in a dark cellar or a radio without batteries will not be of much help when a power outage occurs. Tidying up is therefore an integral part of preparation.

Plan for the specific needs of the household

A generic kit does not take into account daily treatment, an infant, an elderly person, a disability or an animal. Add any prescriptions, emergency glasses, hygiene products, specific food and medical contact information your household may need.

Also explain the plan in simple words. Everyone must know the storage location, the assembly point and the person to contact. A few minutes of discussion avoids a lot of hesitation and allows children to understand the process without worrying them.

Choose understandable and verifiable material

A commercial promise never replaces a standard, instructions or clearly indicated compatibility. Before purchasing a mask, gloves, filter or device, check the risk it addresses, the conditions of use, the necessary consumables and the shelf life.

Then do a test in a normal situation. Turn up the light, tune the radio, wear the mask for a few minutes and learn to remove gloves without touching their outer side. Known and correctly used equipment is always more useful than a sophisticated product discovered in a hurry.

Keep official information at hand

In unusual situations, rumors circulate quickly and can cause people to go out, buy or move at the wrong time. Note the channels of the prefecture, town hall, weather services and Civil Security. Always check the date, location and origin of a message before sharing it.

In case of immediate danger, call emergency services and soberly describe what you see. This site helps to prepare and understand; it does not replace a local alert, a healthcare professional, or specialized teams. The instructions received on site remain priority.

Three essential routes

Prepare methodically, without dramatizing

Visual and concrete paths to move from understanding to action: organize the home, compare protection according to their standards and find public sources which give instructions adapted to each territory.

Essential answers

Frequently asked questions about CBRN risks and the 72 hour kit

Short answers to check an essential point, with links to detailed guides when the situation requires it.

What does CBRN or NRBC mean?

CBRN designates chemical, biological, radiological and nuclear risks. In French, the acronym NRBC presents the same families in a different order: nuclear, radiological, biological and chemical.

What should I do when I receive a FR-Alert alert?

Read the entire message, check the area concerned and apply the indicated instructions: shelter, evacuation or other safety measure. Do not approach danger and follow updates from the issuing authority.

What should you put in a 72-hour emergency kit?

The basics include water, non-cooking food, a battery-powered radio, a lamp, usual treatments, a first aid kit, warm clothes, copies of documents, keys and a phone charger.

How much water should you need for 72 hours?

Civil Security indicates 6 liters of drinking water per person in bottles for the emergency kit. This basis must be adapted to the heat, age, state of health and particular needs of the household.

Does an FFP2 or FFP3 mask protect against chemical gases?

No. An FFP mask filters particles but does not protect against gases, chemical vapors, carbon monoxide or an atmosphere poor in oxygen. An unknown substance requires distancing and emergency services instructions.

Should you take iodine in the event of a nuclear alert?

Only on instructions from the authorities. Stable iodine only protects the thyroid against certain releases of radioactive iodine; it does not protect against other radioactive substances or external irradiation.

Preparation in France

Understand the risks in your territory

Risks and instructions vary depending on the territory. The guide helps households, communities, businesses and ERPs find official sources and prepare a proportionate response.
