Closed operation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear headgear electric powered air purifying respirators and dust, wear rubber acid suit, wearing rubber gloves acid. Away from flammable, combustible material. Avoid generating dust. Avoid contact with acids. When moving to light light unloading, prevent damage to packaging and containers. Equipped with spill response equipment. Empty containers may be harmful residues. When preparing a solution or diluted, should be added to the water base, to avoid boiling and splashing.
Store in a cool, dry, well-ventilated warehouse. Away from fire, heat source. Inside humidity is preferably less than 85%. Packaging must be sealed, do not damp. It should be easy (to) fuel material, acids stored separately, avoid mixing reservoir. Storage areas should be equipped with suitable material spill.
Railway transportation, steel drums gondola transportation available. When complete packaging to shipment, loading should be safe. During transport to ensure that the container does not leak, did not fall, do not fall, no damage. With no flammable or combustible material objects, acids, food chemicals mixed mixed operation. Transport transport vehicles should be equipped with spill response equipment.
Skin contact: Immediately remove contaminated clothing, rinse for at least 15 minutes with plenty of water. Medical treatment. Eye contact: immediately open the upper eyelid, with plenty of water or saline thoroughly washed at least 15 minutes. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: water mouthwash, or egg white to the blues. Medical treatment.
ACCIDENTAL RELEASE AND DISPOSAL:
Isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wear anti-acid. Do not direct contact with leakage. A small leak: Dust to avoid using cleaner shovel collection in a dry, clean, covered containers. You can also rinse with plenty of water, wash water diluted into the wastewater system. Large Leak: recycling or collection shipped to the waste disposal sites. Disposal: should refer to national and local regulations before disposal. And, after dilution, into the wastewater system.
Engineering controls: closed operation, provide safety shower and eyewash equipment.
Respiratory protection: its possible exposure to dust, must wear headgear electric powered air-purifying respirators and dust. When necessary, air respirators to wear.
Eye protection: Respiratory Protection has been protective.
Physical protection: wear rubber acid suit.
Hand protection: Wear rubber gloves acid.
Maximum acceptable concentration MAC (mg / m3): China 2 former Soviet Union: -
Other protection: work now prohibited smoking, eating and drinking, wash hands before eating. After work, take a shower. Pay attention to personal hygiene.
