(1) The gas pipeline should be isolated by a blind plate, all valves except the flue valve should be closed, and the power supply of the valve should be cut off;
(2) The furnace should be well ventilated, the carbon monoxide concentration should be below 24ppm, the oxygen content should be between 18% and 21% (volume concentration), and the gas composition should be analyzed every 2 hours.
(3) When repairing the partition wall of the Industrial Hot Air furnace, use steel to support the partition to prevent the upper bricks from falling off.
3. When overhauling the inside of the hot air pipe, the manhole should be opened to prevent hot gas from entering.
