Sefton warns illegal bonfires can turn a seasonal event into a public health hazard

Sefton Council is urging residents to think twice before lighting or fueling unauthorised bonfires, warning that the piles of discarded items often seen at these events can release toxic smoke, ignite unexpectedly, and put nearby people at risk. The message lands squarely in public health territory: what looks like a community gathering can quickly become a respiratory hazard, a fire hazard, and a fly-tipping offence all at once.

The concern is not limited to the obvious flames. Bonfires that contain tyres, sofas, mattresses, household waste, batteries, gas canisters or appliances can burn unpredictably, with the potential to send hot debris into surrounding crowds if a container or pressurised item explodes under heat. In practical terms, that turns a local celebration into an uncontrolled exposure event, where bystanders may be breathing in smoke from materials that were never meant to be burned in the first place.

Toxic smoke reaches the people least able to absorb the blow

The strongest warning from the council focuses on smoke exposure. Burning mixed waste can generate fumes that irritate the airways and worsen respiratory symptoms, particularly in children, older adults and people already living with asthma, heart disease or other long-term conditions. Those are the residents who often pay the highest price when outdoor air becomes contaminated, even briefly.

A single smoky bonfire is not just a nuisance. It can trigger coughing, breathlessness and chest discomfort in susceptible people, while also placing added strain on those with reduced cardiopulmonary reserve. For families in the area, the risk is not abstract; it can mean a child’s wheeze, an older person’s shortness of breath, or a preventable call for urgent help after exposure to dense smoke.

The council’s warning also reflects a broader environmental reality. Public parks are meant to support physical activity and mental wellbeing, not to serve as disposal sites for rubbish that will be burned in open air. When waste is set alight, the smoke does not respect boundaries, and the people nearby do not get to opt out.

Explosions, flying debris and fast-moving fire spread are part of the hazard

Mixed-material bonfires create a second danger beyond inhalation injury: sudden ignition of items that can explode when heated. Gas canisters, batteries and other sealed or reactive materials can fail violently when exposed to intense heat, scattering hot fragments into the surrounding area. In a crowded setting, even a small blast can cause burns, eye injuries or panic.

Fire spread is another immediate concern. A disorganised fire built from unknown materials is harder to control and more likely to escape its intended area, especially when rubbish has been piled loosely or contaminated with combustible fluids. Once a fire moves beyond a contained burn, the response becomes more complicated and the risk to nearby homes, vehicles, green spaces and emergency responders rises sharply.

This is why the council and Merseyside Fire & Rescue Service are framing the issue as a prevention problem, not just a cleanup problem. Keeping rubbish out of bonfires reduces the chance that a celebratory fire becomes an emergency callout.

Fly-tipping is part of the clinical and civic risk picture

Sefton Council is also reminding residents that placing rubbish on a public bonfire counts as fly-tipping, which can lead to a fine of up to £1,000. The legal point matters, but so does the public health one: fly-tipped material is often exactly the sort of waste that creates toxic smoke, unpredictable flames and environmental contamination when burned.

The warning from councillors Peter Harvey and Joanne Williams ties public behaviour directly to health protection. Harvey described unauthorised bonfires fed with rubbish as selfish, illegal and dangerous. Williams focused on the health risk, saying the council is not trying to stop people from enjoying themselves, but is trying to prevent exposure to potentially toxic or explosive materials. The underlying message is plain: safer celebration should not come at the expense of community health.

Simple prevention steps can reduce the burden on emergency services

Residents are being asked to take straightforward steps that reduce both fire risk and the burden on emergency services. Wheelie bins should be brought in promptly after collection, and neighbours who may need help should be assisted in doing the same. That single habit can reduce the number of bins available for deliberate fire-setting and limit the fuel load for opportunistic arson or bonfires.

The council also warns against giving combustible materials to anyone, especially young people. Petrol, matches and lighters should be stored securely, away from heat sources and out of reach. The logic is straightforward: a small lapse in household storage can fuel a fire that endangers far more than the person who started it.

Residents are also being asked to report fly-tipping through the council’s reporting route and to report unlit bonfires through Merseyside Fire & Rescue Service. Early reporting gives authorities a chance to intervene before a fire spreads or before dangerous material is added to a pile already set up for burning.

The health message reaches beyond one night of fireworks

Bonfire season often gets framed as tradition, but the risks described here are not symbolic. They are concrete and cumulative: smoke exposure for vulnerable lungs, burn injury from unexpected explosions, fire spread into public spaces, and a service burden that can delay firefighters from reaching life-threatening emergencies elsewhere. Each of those outcomes has direct consequences for people living nearby.

There is also a quiet public health cost when parks and communal green spaces are treated as dumping grounds. Residents lose access to places that support exercise, social connection and recovery from daily stress. A park filled with burned waste and debris does the opposite of what green space is supposed to do.

The council’s warning is therefore less about restricting celebration than about preventing avoidable harm. An organised, licensed event is one thing; an unregulated pile of mixed rubbish is another entirely. For residents in Sefton, the safest bonfire is the one that never includes tyres, sofas, batteries, gas canisters or any other unknown material in the first place.
