Prevention

During the fire

Staying indoors during a forest fire

Counter-intuitive but true: if no evacuation order has been given, a solidly built house with cleared undergrowth around it is the best shelter there is. The fire front passes within a few minutes; smoke and panic on the roads claim far more lives. Here is a step-by-step guide to taking shelter.

Key points

  • You should stay indoors if an evacuation has not been ordered and the fire is close by — trying to get out at the last minute is the worst option.
  • Close everything : shutters, windows, hatches, chimney ; switch off the mechanical ventilation and air conditioning ; seal any gaps with damp cloths.
  • Turn off the gas. Move the gas cylinders to a safe distance if you have time; otherwise, alert the emergency services to their presence.
  • Wear loose-fitting cotton clothing, keep a supply of water, a torch and a radio to hand; stay away from windows.
  • It takes a few minutes for the fire front to pass: we only go out once the fire has passed, to put out any remaining hotspots.

Why lockdown helps protect us

The tragedies caused by major fires — both in France and abroad — follow a similar pattern: people caught in the flames or smoke on the roads or by fleeing on foot at the last moment. Conversely, experience shows that a solid building, with the shutters closed, and the surrounding area cleared of undergrowth, protects its occupants whilst the front passes through — which usually lasts only a few minutes in a specific location. The house can then be protected against residual sources of fire (embers in the gutters, smouldering hedges), which are the real cause of most damage.

Absolute exceptions: Mobile homes, caravans, bungalows, garden sheds and lightweight structures do not provide protection. If you are staying in one of these, move to a solidly built building as soon as possible or evacuate in accordance with the instructions — see hiking / camping.

Lockdown: a step-by-step guide

Gather and alert

Everyone inside, including pets. Alert the neighbours by shouting or phoning — remember to vulnerable people. If the fire has not yet been reported: 112.

Sealing the building envelope

Shutters and windows closed (solid shutters protect the windows from direct sunlight), chimney flue closed, mechanical ventilation and air conditioning arrested — they would draw in the fumes. Seal the air inlets and the bottoms of the doors with damp cloths.

Turn off the gas

Turn off the gas supply (cylinders and tanks). If you have time and can do so without putting yourself at risk, move the cylinders away from the building facades; otherwise, leave them where they are and tell the emergency services where they are when they arrive. Leave the electricity on as long as it is working (for lighting and information).

Prepare the water

Fill the bath, sinks and buckets: keep these ready to put out any remaining fires and dampen cloths in case the mains water supply fails. Unroll the garden hose and connect it, keeping it under cover if possible.

Getting kitted out

Loose-fitting clothing made of cotton or wool (never synthetic: it melts on the skin), closed shoes, and a damp scarf to hand. Torch, emergency kit and a nearby radio — the battery-powered receiver comes in handy if the power goes out.

Choosing the right place to settle

In a room opposite the fire front, if possible, away from the floor-to-ceiling windows. If smoke gets in, breathe close to the floor. Keep your mobile with you, but use the network only for essentials — information is shared via FR-Alert and the radio.

After the front had passed

Wait until the situation has clearly calmed down (the heat has subsided, the flames have died down). Go outside carefully, fully equipped, and check the following: guttering, corners of the roof, hedges, woodpiles, the shed — extinguish any remaining hotspots. This routine, repeated over several hours, saved most of the houses. Then it was time for the First steps to take after a fire.

Mistakes that cost a lot

  • Setting off at the last minute “ because it’s getting closer ”: that’s the scenario in road accidents. If the traffic lights are there, you stay put.
  • View from the terrace or the roof : The radiation burns from a distance, and a sudden gust of wind can catch you off guard in a matter of seconds.
  • Douse yourself and go out to face the flames : one only ‘defends’ one’s home after the front has passed, against the embers — never against the front itself.
  • Taking refuge in the swimming pool : The superheated air and the fumes just above the water’s surface make this refuge far more dangerous than it appears (see our common misconceptions).
  • Getting back in the car to ‘ get the family to safety ’ when the axes are obscured: see by car.
At any given location, the fire front usually passes through in 2 to 10 minutes, depending on the vegetation and the wind. This is the central argument in favour of containment: a solidly built structure provides adequate protection for this duration. The next dangerous phase — residual hotspots — lasts several hours and can be managed using a fire hose or a bucket.
If you have the time AND an independent water supply (swimming pool, storage tank), wetting the surrounding area, shutters and gutters can help. Don’t leave it until the last minute: the top priority is to seal off the area completely. And don’t tie up the public water supply, which the fire service needs.
If a wildfire gets out of control, make your way out via the side that has already been burnt (the fire will not return there), taking care to protect yourself, and head for an open area that has already been swept by the fire. Call 112 to report your location.

The risk changes every day. So do your reflexes.
