It is better to not have them in loose fitting or easily inflammable clothes. Always make sure the handles of pans are turned inwards on the burner, so there is no danger of anything being knocked over. Knives, choppers etc should not be used as far as possible during cooking with children. An elder person, or an adult should operate the microwave as well as the gas burners. Cords of appliances should also be tucked away, preferably out of sight and reach.
