Protective measure

Respiratory system protection: Generally no special protection is required, but it is recommended to wear a self-priming filter gas mask (half mask) under special circumstances.

Eye protection: Generally no special protection is required, and chemical safety protective glasses can be worn when exposed to high concentrations.

Body protection: Wear ESD clothes.

Hand protection: Wear general work protective gloves.

Other protection: Smoking is strictly prohibited in the work site. Avoid prolonged and repeated exposure. Supervision is required when entering tanks, restricted Spaces or other high concentration areas.

Leakage emergency treatment

Quickly evacuate the contaminated area to the upper wind, and quarantine, strictly restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and antistatic work clothes. Cut off the source of leakage as much as possible. Cover areas such as drains near the leak with an industrial coat or adsorption/absorbent to prevent gas from entering. Reasonable ventilation to accelerate diffusion. Dilute and dissolve in spray water. Build embankments or dig pits to contain large amounts of waste water. If possible, send the leaking gas to the open area with the exhaust fan or install the appropriate nozzle to burn off. The leak container should be properly disposed of, repaired and inspected before use.

Operation, disposal and storage

Operation precautions: closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevents gas leakage into the workplace air. Avoid contact with oxidants and acids. Cylinders and containers must be grounded and bonded during transfer to prevent static electricity. Light loading and unloading during handling to prevent cylinder and accessories damage. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30℃. It should be stored separately from oxidizers and acids, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. Storage area should be equipped with leakage emergency treatment equipment.

Transportation precautions: The safety helmet on the cylinder must be worn when the cylinder is transported. Cylinders are generally placed flat, and the mouth of the bottle should face the same direction, not cross; The height shall not exceed the guardrail board of the vehicle, and the triangular wooden pad shall be stuck firmly to prevent rolling. Transport vehicles should be equipped with the appropriate variety and quantity of fire equipment. The exhaust pipe of the vehicle carrying the article must be equipped with a fire retardant device, and the loading and unloading of mechanical equipment and tools that are easy to produce sparks is prohibited. It is strictly prohibited to mix with oxidants and acids. Summer should be transported in the morning and evening to prevent sunlight exposure. Stay away from fire and heat sources during the stopover. Road transport should follow the prescribed route, do not stay in residential areas and densely populated areas.
