Precautions
To prevent gas leakage into the air in the workplace. High-purity argon gas should be loaded and unloaded with care during transportation to prevent damage to the cylinder and accessories. Equipped with leakage emergency treatment equipment. When its content increases and the oxygen content falls below., it may cause suffocation. The packaged gas cylinders have a service life on them. All expired gas cylinders must be sent to a department for safety inspection before they can continue to be used. When exhaust gas is used in each bottle of gas, the residual pressure in the bottle should be kept at ., and the minimum residual pressure should not be lower than . The bottle valve should be closed to ensure gas quality and safety. Bottled high-purity argon gas and combustible gases and combustion-supporting gases are strictly prohibited to be stacked together. They are not allowed to be near open flames or heat sources. They should be kept away from fire, oil and wax, explosion in the sun, heavy throwing, and impact.
