What keeps bbq grills from catching fire the minute they are turned on?

BBQ grills are designed with safety features that help prevent fires, such as proper ventilation, heat-resistant materials, and flame tamers that distribute heat evenly. Additionally, many grills have built-in safety mechanisms like thermocouples that monitor temperatures and shut off gas flow if it exceeds safe levels. Regular maintenance, including cleaning grease buildup, also significantly reduces fire risks. Lastly, following proper ignition procedures ensures that gas is safely ignited without creating hazardous conditions.
