Transportation and storage
Operation precautions: closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear a self-priming filter gas mask (half-mask), chemical safety glasses, antistatic overalls, and rubber oil-resistant gloves. Keep away from fire and heat source. No smoking in workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidizer, reducing agent and alkali. When filling, the flow rate should be controlled, and there is a grounding device to prevent electrostatic accumulation. Handling should be carried lightly to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may contain hazardous materials.
