Preparing for Emergencies in Luxembourg: The 72-Hour Guide

Preparing for Emergencies in Luxembourg: The 72-Hour Guide

What if a power outage, a flood, or another emergency disrupted your daily life in Luxembourg for several days? How would you stay informed, contact your loved ones, or meet your family’s basic needs?

In October 2026, the Luxembourg government launched the “Lëtz prepare!” campaign and released its guide, “My Guide—72 Hours of Self-Sufficiency.” The goal is not to alarm the public, but to help everyone better prepare for exceptional situations and know how to respond.

For newcomers and expats, this preparation is particularly useful. When you’re still unfamiliar with emergency services, alert systems, or local assistance programs, a few key pointers can make a real difference.

Here’s what you need to know to prepare for a crisis in Luxembourg, put together your 72-hour emergency kit, and organize your personal emergency plan.

Key Points on “My Guide—72 Hours of Self-Sufficiency”

  • 72 hours: the recommended self-sufficiency period to cover your household’s essential needs during the first few days of a crisis.
  • 3 liters of water per person per day: the minimum amount to include in your supply.
  • 112: the emergency services number in Luxembourg.
  • 113: Emergency number for the Grand Ducal Police.
  • 2025: launch of the national resilience strategy “Lëtz prepare!”
  • 2026: release of the government guide “My Guide – 72 Hours of Self-Sufficiency.”

Why Prepare for Emergencies in Luxembourg?

Luxembourg benefits from modern infrastructure and well-organized public services. However, it is not immune to events that could temporarily disrupt the country’s functioning: severe weather, floods, power outages, technological incidents, or cyberattacks.

A crisis can have very real consequences on our daily lives: you may be unable to use public transportation, pay by credit card, communicate with loved ones, or get your usual supplies.

Through its National Resilience Strategy, the government aims to strengthen the country’s and its residents’ ability to anticipate these situations, limit their consequences, and gradually return to normal operations.

This approach is based on a simple principle: the authorities organize the protection of the population, while each household can contribute to its own safety by stockpiling a few supplies and knowing the right steps to take.

Crisis Preparedness: Key Points for Expatriates

  • Crisis preparedness concerns all residents of Luxembourg, regardless of their nationality.
  • Official LU-Alert alerts are issued in French, German, and English, among other languages.
  • You can receive certain alerts directly on your phone without having to register in advance.
  • Have a family plan in place if you work far from home or if your children attend school in another municipality.
  • Keep a written record of important contact information, especially that of your loved ones living abroad.
  • Preparedness does not mean living in constant worry; it means anticipating a few essential needs.

What are the main risks in Luxembourg, and how can you prepare for them?

Not all risks have the same likelihood or the same consequences. The government guide identifies several situations that may require a rapid response or a temporary adjustment to your daily routine.

Storms, heavy rain, snow, and heat waves

Weather events can disrupt travel, damage certain infrastructure, or pose health risks.

When a weather alert is issued, check the official forecasts on MeteoLux and follow the authorities’ recommendations.

Depending on the situation, it may be necessary to limit travel, secure objects exposed to the wind, or take special precautions against the heat.

Floods: Check for risks around your home

Heavy rainfall can cause high water levels and flooding, particularly in areas near waterways.

If you have recently rented or purchased a home in Luxembourg, it may be helpful to check its flood risk exposure on the Water Geoportal.

During periods of high water, visit inondations.lu and follow the instructions issued by the authorities. Avoid flooded roads, riverbanks, and exposed basements.

Power Outages and Disruptions to Essential Services

A prolonged power outage can have repercussions far beyond lighting and heating. Communication networks, transportation, electronic payments, water supply, and certain businesses may also be disrupted.

It is precisely to cope with this type of situation that the government recommends being prepared to meet your basic needs for at least 72 hours:

  • a radio that works without household electricity,
  • a battery-powered lamp,
  • a supply of water
  • food that is easy to eat

can help you maintain a certain degree of self-sufficiency.

Cyberattacks and Digital Disruptions

Cyberattacks can affect individuals, businesses, or government agencies. They can lead to data theft, fraud, or the unavailability of certain digital services.

To reduce these risks, adopt good habits:

  • unique passwords,
  • two-factor authentication,
  • regular updates,
  • backing up important documents.

If you receive a suspicious message, verify the information directly on the official website of the relevant organization. NEVER click on a link received via text message or email.

Industrial and Nuclear Accidents and Security Threats

The government also takes into account less frequent but potentially serious events, such as industrial accidents, nuclear incidents, or threats to public safety.

Instructions will depend on the nature of the event: taking shelter, travel restrictions, evacuation, or other protective measures.

In the event of a nuclear alert, do not take iodine tablets on your own initiative: their use must follow the authorities’ instructions.

For these situations, consult the official recommendations published on Infocrise.lu.

LU-Alert: How to Receive Official Alerts in Luxembourg?

When an emergency occurs, it is essential to be able to distinguish official information from rumors or unverified messages.

Luxembourg has LU-Alert, a national alert and information system that allows authorities to warn the public before, during, and, depending on the circumstances, after a dangerous event.

The various alert methods

Depending on the severity and nature of the situation, authorities can disseminate their messages through several complementary channels.

ChannelHow It WorksWhat You Should Do
Geolocated SMSMessage sent to phones located in the affected area.No prior registration required.
Cell BroadcastPriority notification on compatible phones.Check your phone’s compatibility and for updates.
LU-Alert AppCustomizable alerts and information by area and category.Install the app and enable notifications.
Official websites and mediaDetailed information and updates on the situation.Check LU-Alert and reputable media outlets.
SirensAudible warning signals depending on the activated systems.Get to safety and follow official instructions.

Our advice: Install the LU-Alert app as soon as you arrive in Luxembourg. You’ll be able to select the geographic areas that interest you, such as your municipality of residence and your workplace.

To view alerts and learn how the system works: www.lu-alert.lu.

Understanding Alert Levels in Luxembourg

The LU-Alert system distinguishes between several alert levels based on the severity of the event.

  • Yellow: Stay alert to how the situation develops.
  • Orange: Exercise caution and take the recommended precautions.
  • Red: Exercise extreme caution in the face of a significant danger.
  • Purple: Imminent danger requiring immediate action.

Regardless of the level, the priority remains to follow the instructions provided in the official message.

How can you stay informed without internet or electricity?

In the event of a major disruption to communication networks, the radio can become an essential means of receiving information from the authorities.

The government guide specifically recommends having a battery-powered radio that allows you to listen to national stations, including RTL and Radio 100.7.

It’s also helpful to know in advance which information channels your municipality uses.

What do the Luxembourg authorities do in the event of a crisis?

Individual preparedness obviously does not replace government action. Luxembourg has crisis management mechanisms that mobilize, depending on the circumstances, national authorities, municipalities, emergency services, and operators of critical infrastructure.

National Coordination to Protect the Population

When a major crisis requires it, the authorities can activate the appropriate response plans and establish a crisis management team.

In the scenario of a widespread power outage presented in the guide, response efforts focus in particular on assessing the disruptions, gradually restoring the power grid, protecting critical infrastructure, and keeping the public informed.

Emergency services, the Grand Ducal Police, and other relevant actors respond in accordance with their respective mandates.

The Role of Municipalities and Local Solidarity

Municipalities also play an important role in preparing andsupporting residents.

Depending on the nature and scale of the crisis, local measures can be organized to inform the public, support vulnerable individuals, or provide temporary shelters.

For expatriates, it is therefore particularly useful to be familiar with their municipality, the municipal communication channels, and a few people in their neighborhood.

Why plan for 72 hours of self-sufficiency?

A 72-hour self-sufficiency period does not mean that emergency responders will systematically take three days to arrive. This timeframe serves as a practical guideline to enable each household to meet its basic needs during the initial stages of a crisis.

This allows emergency services to focus their efforts on the most serious situations and on people who need immediate assistance.

For a family, this primarily means having water, food, means of staying informed, lighting, hygiene products, and items necessary for their specific needs.

How do you put together a 72-hour emergency kit?

Good news: putting together an emergency kit doesn’t mean turning your home into a warehouse. Start by checking what you already have, then gradually add any missing items.

The kit should be tailored to the number of people in your household, their ages, their health conditions, and their specific needs.

Water and Food: Essential Supplies

Allow at least 3 liters of water per person per day, or 9 liters for one person over 72 hours.

Supplement this supply with non-perishable foods that are easy to store and eat, taking into account your family’s eating habits and needs.

Don’t forget the special needs of infants and pets.

Lighting, Information, and Communication

Make sure you have a battery-powered flashlight, appropriate batteries, a radio that works without household electricity, and a portable charger for your phone.

This equipment allows you to maintain a minimum level of lighting, follow official instructions, and communicate while networks remain available.

Health, Hygiene, and Important Documents

Your kit should also include a first-aid kit, essential hygiene products, and any medications your household members need, based on their usual requirements.

Keep a copy of your essential documents in a protective sleeve: identification, insurance policies, medical contact information, and other useful details.

Checklist: Your 72-Hour Emergency Kit

  • A supply of drinking water sufficient for the number of people in your household.
  • Non-perishable, easy-to-eat foods.
  • A flashlight and spare batteries.
  • A battery-powered or hand-crank radio.
  • A fully charged power bank.
  • Blankets and clothing appropriate for the season.
  • A first-aid kit and any necessary medications you usually take.
  • Essential hygiene items.
  • Copies of important documents.
  • A written list of useful phone numbers and some cash.
  • Items specifically for children, dependent adults, and pets.

To-do: Check your kit at least twice a year, paying particular attention to expiration dates and the condition of the supplies.

Preparing Your Personal Emergency Plan in Luxembourg

Having supplies on hand is the first step. But do you know how to organize yourself if phone networks are down, if public transportation is disrupted, or if your family is in different locations when a crisis strikes?

That is precisely the purpose of the personal emergency plan proposed by the government.

Determine how to communicate with your loved ones

Identify the people you need to contact and keep their contact information on paper. If your family lives in multiple countries, also designate a contact person abroad.

Discuss as a family how you’ll communicate if phones or the Internet stop working normally.

Plan for travel and meeting places

Decide in advance where household members can meet if their usual routes become impassable.

This planning is especially important when parents work in different towns or when children attend school far from home.

For families, it’s helpful to know the procedures put in place by schools and the people authorized to care for the children.

Anticipate the needs of vulnerable individuals

If a family member needs special assistance, factor this into your preparations: medications, necessary equipment, medical contacts, and people who can provide help.

This is particularly important for older adults, people with disabilities, and those whose independence depends on regular support.

You can find more information on support and assistance services in Luxembourg.

Keep a Hard Copy of Your Plan Accessible

Once your plan is complete, keep a paper copy in a location known to all household members.

The government provides a fillable template containing the essential information needed to organize your response in an emergency.

Important in a crisis

In a crisis, instructions from the authorities always take precedence over your personal plans. Depending on the situation, you may need to take shelter or evacuate the area. Do not leave on your own without following official instructions.

Never use outdoor-only combustion appliances inside a home, especially for cooking or heating. They pose a serious risk of carbon monoxide poisoning.

The emergency numbers 112 and 113 should be reserved for situations that truly require the intervention of emergency services or the police.

How can you prepare when you’ve just moved to Luxembourg?

Moving abroad often means finding your bearings again: a new home, new routines, new people to interact with, and sometimes family who are geographically distant.

To be better prepared, start with a few simple steps:

  • Find out how your municipality shares information.
  • Install LU-Alert and check your phone’s settings.
  • Find out the emergency numbers in Luxembourg.
  • Check whether your home is located in a flood-prone area.
  • Keep your doctor’s contact information and the contact details of people to notify on hand.
  • Talk to your family about what to do if communications are disrupted.
  • Get to know a few neighbors and identify people who might need help.

These precautions will help you get to know your surroundings better while making it easier for you to integrate into local life.

Common Mistakes to Avoid During a Crisis

  • Thinking that an emergency cannot happen in Luxembourg.
  • Relying solely on your phone to find important contact information.
  • Waiting until a crisis strikes to buy essential supplies.
  • Forgetting the specific needs of children, vulnerable people, or pets.
  • Never checking your supplies and expiration dates.
  • Sharing alarming information without verifying its source.
  • Confusing personal preparedness with replacing emergency services.

Lëtz prepare!: Individual and Collective Preparedness

Resilience does not rely solely on material supplies. It also depends on residents’ ability to stay informed, cooperate, and help one another.

An isolated neighbor, a newly arrived family, or an elderly person may need special support. Without putting yourself at risk, everyone can help strengthen this local sense of solidarity.

Preparedness can also involve learning first aid or getting involved with community organizations. Discover the opportunities for volunteering in Luxembourg.
