SMSTS Course’s Derek Hales reveals the BBQ mistakes that could ruin your weekend – and your health:
With sunshine making an appearance across the UK this weekend, thousands will be dusting off their barbecues – but construction safety expert Derek Hales from SMSTS Course is urging Brits to apply some of the same safety thinking used on building sites to their back gardens.
“We talk a lot about hazards in the workplace – but BBQs carry just as many risks when the right checks aren’t made,” says Hales. “And people often don’t realise it until they’re either ill or injured.”
The Most Overlooked BBQ Dangers – According to Safety Experts
Charcoal Poisoning Indoors or Undercover
It might be tempting to take the party indoors if the weather turns – but using a charcoal BBQ in a garage, tent, or under a gazebo can quickly lead to carbon monoxide poisoning. It’s odourless, silent, and deadly.
Reusing Old BBQ Coals
Half-burnt coals from last year might save money, but they can release harmful chemicals and don’t reach the temperatures needed to cook meat safely.
Cross-Contamination From BBQ Utensils
Many people flip raw meat with tongs – then use the same ones for cooked food. That’s a fast track to food poisoning. Always separate utensils for raw and cooked meat.
Using Flammable Liquids Like Petrol or Paint Thinners
It happens more often than you think. Only use BBQ-safe firelighters. Industrial liquids can explode and release toxic fumes.
Not Letting the Grill Heat Properly
Undercooked chicken and sausages are a classic summer BBQ fail. It takes 10–15 minutes for most grills to reach safe cooking temperatures – rushing it increases the risk of campylobacter or salmonella.
Cleaning Grills With Wire Brushes
Tiny metal bristles from old grill brushes can break off and embed in burgers or hot dogs, causing serious internal injuries if swallowed. Use natural alternatives like onion halves or heat-proof scrapers.
Poor Gas Maintenance
For gas BBQ users, cracked hoses, loose regulators, or leaky connections can cause flare-ups or even explosions. A simple soapy water test can reveal leaks before you turn the gas on.
Hales adds: “Whether you’re in a garden, on a balcony, or in a park – take a few minutes to run through basic checks.
“The goal is to enjoy the sunshine, not end up in A&E.”
