That’s a smart and safety-conscious question, especially since you’re installing benches near a barbecue area. The short answer is: not all street benches automatically come with fire retardant treatment, but in your case, they likely should.
First, check the manufacturer’s specifications. Many standard outdoor benches are made from materials like untreated wood, metal, or recycled plastic. Untreated wood is highly flammable, especially near open flames, sparks, or hot charcoal. Metal benches are non-combustible but can get dangerously hot in direct sunlight or near a grill. Some recycled plastic benches may include flame retardant additives, but this varies widely by brand and local fire codes.
Second, local regulations often require fire-resistant materials for public furniture within a certain distance of cooking or fire sources. For example, in the U.S., ASTM E84 (flame spread index) standards are commonly referenced. A Class A rating indicates the best fire resistance. You should ask your supplier if the benches meet this standard, or if they have been treated with an approved fire retardant coating.
If the benches are already installed and untreated, don’t panic. You can apply a clear, weather-resistant fire retardant spray specifically rated for outdoor use. Just remember that these treatments may need reapplication after heavy rain or every 1-2 years, depending on the climate.
Lastly, for practicality and peace of mind, consider positioning the benches at least 5-10 feet away from the grills or fire pits. Combine that with fire-resistant materials like powder-coated steel or concrete-look benches, and you’ll greatly reduce risk.
In short: ask for material data sheets (MDS) or certification from your vendor, and if in doubt, apply a tested fire retardant treatment. Safety first, especially around sizzling barbecues.
