Look for a safety valve in your burners?

This feature is optional and may not be available with all the burners. A safety valve is a heat sensing device and is placed near the burner & controls the gas supply to the valve. As long as it senses the heat, it ensures constant gas supply to the burner.  In case of the burner accidentally turning off due to wind or due to overflowing of any liquid, the safety valve senses the absence of heat and automatically turns off the gas supply to the burner. This ensures safety and is also called child proofing.
