Nitrogen is a colorless, odorless, non-toxic, non-flammable high-pressure gas stored in a gas cylinder. When its content increases and the oxygen content is lower than 19.5%, it may cause suffocation. Requires self-priming breathing mask. The bottled nitrogen product is a high-pressure filling gas, which should be used after decompression and decompression. Packed gas cylinders have a service life. Any expired gas cylinders must be sent to a department for safety inspection before they can be used. When the exhaust gas of each bottle of nitrogen is used, the residual pressure in the bottle should be kept at 0.5MPa, and the minimum pressure should not be less than 0.25MPa. The bottle valve should be closed to ensure gas quality and safe use. Bottled nitrogen should be stacked and stored separately during transportation, storage and use. It is strictly forbidden to stack flammable gas and combustion-supporting gas together. It is not allowed to be close to open flames and heat sources. Impact, it is strictly forbidden to conduct arc or arc on the cylinder, and brutal loading and unloading are strictly prohibited.
Closed operation, provide good natural ventilation conditions. Operators must undergo special training and strictly abide by the operating regulations. Prevent gas from leaking into the workplace air. Handle lightly during handling to prevent damage to cylinders and accessories. Equipped with leakage emergency treatment equipment.
Fire emergency measures and protection:
Quickly evacuate personnel from the leaked contaminated area to the upper wind, and isolate them, strictly restricting access. It is recommended that emergency personnel wear self-contained positive pressure respirator. Do not directly touch the leakage. Cut off the source of the leak as much as possible. Prevent gas from accumulating in low recesses and catching fire and exploding when ignited. Use the exhaust fan to send the leaked air to the open space. Leaky containers must be properly handled, repaired and inspected before use.
