Gas and electric goods must be checked CONSUMERS of gas and electrical products are being urged to make sure their appliances are in proper working condition. The NSW Department of Fair Trading said it's important that before operating any piece of equipment, users understand the manufacturer's instructions. "All gas barbecues and small camping gas appliances must be approved to be legally sold, so make sure your product has an approval mark," NSW Fair Trading Commissioner Rod Stowe said on Friday. LP gas cylinders and attached equipment can kill or injure if a gas leak occurs. Check hoses on barbecues, they can crack and perish. So far this year, the department has received eight complaints and 27 inquiries about gas and electrical product and appliance safety. Particular care should be taken when using small gas cookers, commonly known as lunchbox cookers, the department said.
