OPERATION CAUTIONS 

Airtight operation, strengthen ventilated. Operators must receive special training, strictly abide by the operation procedures.

Suggest operators wear self-priming filter type dust mask, wearing chemical safety protective glasses, wear gas permeability

overalls, wear rubber gloves. Away from fire and heat source, the workplace smoking is strictly prohibited. Use

explosion-proof ventilation systems and equipment. Avoid dust. Avoid contact with the oxidant. Light light discharge

when handling to prevent damage to packaging and container. Equipped with corresponding varieties and number of fire

equipment and spill contingency processing equipment. Empty containers may remain inside.

Storage precautions

Store in a cool, ventilated warehouse. Away from fire and heat source. Should be stored apart and oxidant, avoid by all means is

mixed reservoir. Equipped with corresponding varieties and number of fire equipment. Storage area should be

equipped with the right material for leakage content.

Transport considerations

Packing should be full of shipment, the loading should be safe. Transportation process to ensure that the container does not leak,

collapse, fall, and not damaged. It is strictly prohibited and oxidant, such as food chemicals during conventional. Transit

should prevent insolate, rain, heat. Transportation vehicles should make a thorough cleaning.
