Precautions: Bottled gas products are high-pressure filling gas, which can only be used after pressure reduction. The packaged gas cylinders have a service life, and any expired gas cylinders must be sent to a department for safety inspection before they can continue to be used. When using exhaust gas in each bottle, the residual pressure inside the bottle should be kept at 0.5MPa, which should not be lower than 0.25MPa. The bottle valve should be closed to ensure gas quality and safe use. Bottled gas products shall be stacked by categories during transportation, storage and use. Combustible gas and combustion supporting gas shall not be stacked together, and shall not be close to open fire and heat source. It shall be kept away from fire, oil wax, explosion, heavy throwing and impact. Arc striking or arc striking on the cylinder body is strictly prohibited, and rough handling is strictly prohibited.
