Arthur’s Seat Fire: experts warn of glass bottle fire risk

Sunday’s wildfire at Edinburgh’s Arthur’s Seat, was thought to have been started by ‘human activity’. While this could be a range of things, one possible reason could be discarded litter.

Glass waste experts at BusinessWaste.co.uk warn locals that discarded litter, particularly glass, left in direct sunlight and near grass, can ignite and spread quickly. To help reduce the risk of more fires, they are urging locals to carefully dispose of empty glass bottles to prevent fires. 

What’s the risk?

Wildfires are on the rise, with research finding that by April 2025, the UK had already surpassed records for the area of land burnt by wildfires.

So far this year there have been 175 fires, burning an area of over 40,000 hectares – that’s an area more than twice the size of the city of Glasgow.

Fires like these are becoming more common due to climate change. One study found that human-induced climate change makes the dangerous conditions needed for wildfires at least six times more likely.

Why is glass waste an issue?

Glass waste, specifically any that’s clear or curved like drinks bottles, can act as a magnifying glass in direct sunlight and start fires. The magnifying effect of glass can project the sun’s rays onto dry material like grass, wood, or paper. When this reaches a certain temperature it can ignite a fire. Combine this with dry and windy conditions, and fires spread quickly.

While this may sound an unlikely combination of factors, it’s more common than many people realise. For example, a fire in the Peak District in May was attributed to discarded bottles, and a similar situation was seen on the Isle of Arran in April. 

Outside of wildfires, glass also poses a risk in the home. Residents should be careful when disposing of glass into open top bins, especially when combined with other combustible materials found in dry mixed recycling, such as paper and cardboard. Alongside this, a single glass bottle left on dry garden grass could be enough to start a fire. 

Beyond the obvious risk to health and life, wildfires, especially those that burn the UK’s moorland, can be ecologically devastating. They can wipe out whole ecosystems and make local areas more prone to future flooding. 

How should you dispose of glass?

If you take any glass bottles with you to open outdoor spaces, you should always take them home with you. Never leave glass exposed in direct sunlight for long periods of time, especially alongside dry vegetation and materials like paper and cardboard. 

Glass should always be recycled. Waste glass is a valuable resource that can be constantly recycled into new glass products. If glass is sent to landfill, the raw material is lost and more must be mined to create new products. Recycling glass saves up to 30% of the energy compared to making new glass from raw materials.

What to do if you spot a fire

First, ensure you get yourself and anyone you are with to safety. Once you have done so, call 999 to report the fire. Try to give as much detailed information as you can about the location – What3Words can be helpful to pinpoint fires. Never attempt to put out a wildfire yourself, as these types of fires can behave erratically. 

What are the consequences if your litter leads to a fire?

If your litter causes a fire, and you left this ‘deliberately’ or ‘recklessly’, this might be classed as arson5 under the Criminal Damage Act 1971. This could result in a criminal record, unlimited fines, and even a prison sentence. 

Littering itself can see you issued with a Fixed Penalty Notice of up to £500, or a fine in court of up to £2,500.

Graham Matthews, glass waste expert at BusinessWaste.co.uk, said: “Many people aren’t aware of the danger discarded glass poses. But as the weather heats up, it’s essential that the public are careful with all waste.

“We know that climate change is only escalating the risk of wildfires across the UK, and we have seen many concerning instances of just a single glass bottle being responsible for burning huge swathes of the countryside

“We urge people to be responsible and considerate with any glass waste, both in and outside the home. You should always take your litter with you regardless, but the consequences are so much higher in hot, dry weather.

“While leaving glass bottles unattended or littered may seem like a simple moment of carelessness, the lasting impact on our environment can be huge.”

Study finds that 96% of us not testing smoke alarms regularly enough

A study by online training provider High Speed Training has found that 96% of GB residents are not testing their smoke alarms as regularly as recommended, and that less than half have a fire escape plan for their home.

  • In the year 2020/21, fire services in England, Scotland and Wales attended over 630,000 total incidents, tragically resulting in over 300 fatalities.
  • Many of these incidents occur in the home. In fact, 20 people are injured or killed every day just by accidental fires that start in their kitchens.
  • As part of a report on residential fire safety, High Speed Training surveyed over 2000 GB adults, and found that an incredibly high number [96%] were not engaging in weekly testing as is recommended by fire services.

Smoke alarms are one of the most effective defences against fatal fires in the home, with estimates suggesting that you are eight times more likely to die in a fire if your home does not have working smoke alarms.

There should also be one smoke alarm placed on every level of a home, which was the case with 84% of the survey respondents.

In private rented and social rented homes, it is the duty of the landlord to ensure a suitable number of smoke alarms are installed and functional at the beginning of the tenancy, with at least one smoke alarm on each storey where a room is used as living accommodation. 

If a fire does break out in your home, having an agreed escape plan is essential to increase your chances of escaping without serious injury. The main key to a good fire escape plan is to include alternate routes to safety in case one exit is blocked or dangerous to use. 

Though escape plans are recommended by fire services, the survey found that 55% of people in the GB do not have a fire escape plan in place in their home. The report also found that younger generations are less likely to have a plan in place, with 68% of 18-24 year olds saying they don’t have or don’t know if they have a plan.

In contrast, 45-55 year olds are most likely to have a plan, with 51% stating they have an escape route prepared. 

Faulty electrics, including appliances, wiring, and overloaded sockets, cause around 4,000 house fires in England every year. The maximum current allowed to safely flow through the socket (power rating) should be clearly marked on the back or underside of the extension lead. If not, you should refer to the manufacturer’s instructions. 

High Speed Training’s report found that 77% of respondents were unsure on how to check either the voltage or the amperage levels of a socket.

Closing all of the internal doors in your home is one way to increase your chances of being able to escape from a house fire. A closed door can hold back fire and smoke, and buy you precious time to escape. However, in our survey, we found that 66% of people don’t close their internal doors every night.

Another simple step to add to your routine is to make sure that your exit route is clear of trip hazards. In the disorientating smoke of a house fire, objects on the floor could pose a real risk. Our survey found that a huge 71% of respondents don’t ensure their exit routes are clear every night.

William Cunningham MIFSM, MIIRSM, GradIOSH, DipFD, Director of Safety Group and Fire Safety Consultant, said: “Over the last few years, we have all spent more time at home. It is so important that we make sure that our homes are as safe as possible, minimising the risks of a fire breaking out, and maximising our chances of escaping safely if one does.

“Having spent over 15 years working in fire safety, I can say that the steps included in this report, such as regularly testing properly placed smoke alarms, ensuring you have an escape plan, and not overloading sockets, are simple and practical ways to improve the fire safety of your home.

“The stats that High Speed Training have found show that many households across the UK could be doing more to reduce the risk of a fire breaking out in their homes. There is a real need to raise awareness of what can be done to improve fire safety across the country.

“By following the advice suggested in this report and by fire services across the country, we can decrease the risk of serious and potentially fatal fires occurring in our homes.”

Richard Anderson, Head of Learning and Development at High Speed Training, said: “This report really highlights the need for everyone to have an awareness of how important it is to practise good fire safety at home.

“The steps outlined in this report are practical and accessible, and can easily be adopted by all homes to minimise the risk of a tragic fire.

“We would encourage everyone to assess the current situation in their home, and make any necessary changes to improve the fire safety of their property.”
