Safely planning a fire pit in the garden
A fire pit seems straightforward at first glance: set up a bowl, put wood in it, and light it. In practice, however, preparation determines whether the evening remains relaxed or unnecessary risks arise.
Open flames, high temperatures, sparks, and embers require a location that not only looks good but also remains safe in changing winds and with prolonged use.
Therefore, before a fire pit is lit for the first time, the location, subsoil, distances, fuel, and extinguishing options should be considered together.
First, check local regulations
Whether a fire bowl or a campfire is allowed on your own property can vary regionally. Federal states and municipalities can set requirements for size, distances, registration obligations, or operation during dry periods.
Protected areas, proximity to forests, or municipal ordinances can also play a role. The federal portal points out that local authorities may require further regulations and special safety measures.
Therefore, before the first use, you should check:
- Is there a local ordinance on open fires?
- Is the property near a forest or protected area?
- Is there currently an increased risk of forest or grassland fires?
- Are specific distances prescribed?
- Does a larger fire need to be registered?
If in doubt, the local public order office, environmental office, or the responsible municipality is the right point of contact.
The right location
A fire pit belongs in an open, clear area. Overhanging branches, dry hedges, woodpiles, garden sheds, fences, and parasols must not be directly within the range of heat and sparks.
The fire pit should also be placed so that it can be observed throughout its operation. A spot behind a wall, a shed, or out of direct sight is unsuitable.
The German Fire Brigade Association and the vfdb recommend a minimum distance of five meters from buildings or combustible building parts for outdoor fire pits. For particularly flammable materials, at least 25 meters are recommended. These recommendations do not replace stricter local regulations.
Not only the visible flame is relevant. Heat radiation and flying sparks can also heat up or ignite objects at some distance.
Consider wind direction and neighborhood
The location should not be assessed exclusively in calm weather. Even light wind can carry smoke and sparks in an unexpected direction.
Therefore, check before each ignition:
- Where does the smoke go?
- Are there open windows or doors there?
- Is laundry hanging outdoors in the neighborhood?
- Are there dry plants in the wind direction?
- Can the wind suddenly accelerate between buildings?
Even with suitable wood, smoke contains health-damaging substances. The Federal Environment Agency mentions fine dust, carbon monoxide, and organic compounds, among others. People with asthma, COPD, or cardiovascular diseases can react particularly sensitively.
Therefore, a fire pit should not be operated if smoke regularly drifts onto neighboring properties or into living spaces.
Which surface is suitable?
The fire pit must stand securely on a level and non-combustible surface. Suitable options include flagstones, paving, gravel areas, or specially designed fireproof base plates.
Unsuitable surfaces include:
- dry lawn,
- wooden decking without an approved protective solution,
- plastic coverings,
- dry soil with plant debris,
- areas directly over roots,
- uneven surfaces on which the fire pit could tip over.
Considerable heat can also develop under a fire bowl. The feet of a bowl alone do not guarantee that a sensitive surface will remain undamaged.
For fire baskets, it is also important to note that embers can fall out through side openings or the bottom. The non-combustible area should therefore be significantly larger than the actual base area of the fire basket.
The Federal Environment Agency expressly recommends operating fires only in designated fireproof containers and on a fireproof surface.
Safety distance to garden furniture
Chairs and benches should not be placed directly at the fire pit. People change their seating position during an evening, stand up, or move around the fire with drinks and blankets.
Particularly lightweight plastic furniture, cushions, blankets, and pillows must be kept at a sufficient distance. They can be damaged by heat radiation or catch fire from flying sparks.
The seating area should be arranged so that everyone can leave the area without having to pass close to the fire pit. A clear walkway is particularly important if children, older people, or pets are present.
Only use suitable firewood
For a fire bowl, dry, well-seasoned, and untreated wood is the right choice. Damp wood burns poorly and produces more smoke.
Do not put the following into the fire pit:
- varnished or coated wood,
- treated lumber,
- furniture parts,
- chipboard or MDF,
- plastic,
- packaging materials,
- garden waste and leaves,
- wet green waste,
- old wood of unknown origin.
Burning treated materials can release toxic substances. The Federal Environment Agency particularly warns against dioxins and furans, which can be produced when burning treated or varnished wood. Garden waste generally should not simply be disposed of in a private fire pit.
A fire pit is not a means of waste disposal.
Lighting a fire correctly
Dry kindling, wood wool, or designated solid firelighters are suitable for lighting. The Federal Environment Agency refers to the requirements of DIN EN 1860-3 for firelighters.
Petrol, spirit, and other liquid accelerants must never be used. Their vapors can ignite suddenly and cause uncontrollable flash fires.
Refilling an already smoldering or seemingly extinguished fire is particularly dangerous. Invisible vapors can ignite in an instant.
The German Fire Brigade Association expressly warns against using spirit and other flammable liquids when lighting fires and barbecue coals.
Build up the fire slowly
Start with a small amount of wood. A fire bowl does not need to be filled to the brim to create a pleasant atmosphere.
Too large a fire causes:
- stronger heat radiation,
- more smoke,
- higher spark emissions,
- faster refuelling,
- greater extinguishing effort.
The wood should remain within the designated burning area. Logs that are too long and protrude over the edge can fall down or heat surrounding objects.
Only add as much fuel as can burn in a controlled manner.
Never leave a fire unattended
At least one responsible adult must observe the fire at all times. This also applies even if only embers are visible.
Children and pets cannot reliably estimate distances. A clear boundary around the fire pit helps to make the danger zone visible.
Even diminishing flames do not mean that there is no longer any danger. Metal parts, embers, and ash can remain very hot for a long time.
The Federal Environment Agency recommends keeping the fire pit under constant observation. The German Fire Brigade Association advises not to leave the site until the fire and embers are completely extinguished or cooled.
Keep extinguishing agents ready
Before lighting the fire, it must be clear how it can be extinguished in an emergency.
For a classic wood fire pit, at least a sufficiently large container of water should be available. Depending on the situation, sand or a suitable fire extinguisher may also be useful.
Extinguishing agents do not belong in the garden shed on the other side of the property. They must be immediately accessible.
For gas-powered fire pits, the manufacturer's operating instructions are decisive. The gas supply must be able to be safely shut off at all times. If there is a smell of gas, the appliance must not be ignited or operated further. Open flames and other sources of ignition must be kept away.
If a fire gets out of control, dial 112 immediately. The German Fire Brigade Association expressly advises against waiting to see if the situation might calm down on its own.
No fire in strong winds or dry conditions
No open fire should be operated in strong winds. Sparks can be carried over long distances and ignite dry plants, roofs, or wooden surfaces.
Prolonged dry periods also significantly increase the risk. Dried-up grass, dry leaves, and hedges can catch fire even from small embers.
Before use, current warnings and the regional forest fire danger level should be checked. In case of increased danger, refraining from lighting a fire is the only sensible decision.
The Federal Environment Agency recommends not lighting a campfire in strong winds or dry conditions. If the wind picks up significantly during operation, the fire should be extinguished in a controlled manner.
Completely extinguish the fire
At the end of the evening, the fire pit must not simply be left to itself.
Carefully distribute larger embers within the bowl and extinguish them in a controlled manner. Then check whether there is still heat, smoke, or glowing.
Even seemingly cold ash can still contain embers inside. Therefore, it must not be immediately placed in plastic containers, garbage bins, or on the compost heap.
The Federal Environment Agency recommends disposing of completely cooled ash with household waste. It is not suitable for garden soil or compost, as heavy metals and combustion residues can accumulate in the soil.
Maintenance after use
A clean fire pit lasts longer and can be better inspected before its next use.
Remove completely cooled ash and check:
- Is the bowl still stable?
- Have cracks or significant deformations formed?
- Are screws and feet tight?
- Is rust only superficial or already weakening the material?
- Are hoses and connections undamaged on gas appliances?
- Can rainwater and moisture drain away?
A cover can protect the material from precipitation. However, it should only be applied once the fire pit and ash have completely cooled down.
For gas-powered models, the manufacturer's maintenance and storage instructions also apply.
The most important rules for a relaxed evening
A safely operated fire pit does not require a complicated setup. However, it does demand attention and preparation.
The location must be open, stable, and sufficiently far from flammable materials. The surface must be able to withstand the heat generated. Only suitable, dry, and untreated wood may be burned.
Weather and wind direction must be re-evaluated before each use. Extinguishing agents must be ready, and the fire pit must never be left unattended until it is completely extinguished.
Conclusion
A fire pit is not made safe by a high-quality product alone. Only the combination of a suitable location, a fireproof surface, appropriate fuel, and responsible behavior ensures controlled operation.
Anyone who considers these basics during the planning phase not only protects their own garden. Neighbors, animals, buildings, and the surrounding nature are also protected from avoidable burdens and dangers.
This way, the fire remains what it should be: a peaceful focal point for long evenings outdoors.
