3. ** DANGER OF FIRE AND EXPLANCE **: This product is non-flammable, highly corrosive, irritating, and can cause burns to the human body.
IV. First aid measures
1. ** SKIN CONTACT **: Immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. ** EYE CONTACT **: Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. ** INHIBITION **: Quickly remove from the scene to a fresh place of air. Keep the respiratory tract Such as breathing difficulties, give oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.
4. ** Ingestion **: Gargle with water, give drink milk or egg white. Seek medical attention.
5. Fire protection measures
1. ** Hazardous characteristics **: by hot topic decomposition to produce toxic sulfide flue gas. Reacts with acids, emitting toxic and flammable hydrogen sulfide gas.
2. ** Hazardous combustion products **: hydrogen sulfide, sodium oxide.
3. ** Fire extinguishing method **: Fire personnel must wear full body acid and alkali fire suit. When extinguishing fire, move the container from the fire site to an open place as much as possible. Then select the appropriate extinguishing agent to extinguish the fire according to the cause of the fire.
6. Emergency treatment for leaks
1. ** Emergency treatment **: Quickly evacuate personnel from the leaked contaminated area to a safe area, and isolate them, strictly restricting access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-acid and alkali work clothes. Do not come into direct contact with leaks. Cut off the source of leaks as much as possible.
2. ** Small leaks **: Absorb with sand, vermiculite or other inert materials. It can also be rinsed with a large amount of water, diluted with washing water and placed in the wastewater system.
3. ** Large leaks **: Build a dike or dig a pit for containment. Transfer to a tanker or special collector with a pump, and recover or transport to a waste disposal site for disposal.
VII. Operation Disposal and Storage
1. ** Operating Precautions **: Closed operation, local exhaust. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (full face masks), rubber acid and alkali-resistant clothing, and rubber acid and alkali-resistant gloves. Avoid generating fumes. Prevent the release of fumes and vapors into the air of the workplace. Avoid contact with oxidants and acids. When handling, it should be handled lightly to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Harmful substances may remain in emptied containers.
2. ** Storage precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The humidity in the warehouse should preferably not exceed 85%. The package must be sealed and should not be damp. It should be stored separately from oxidants and acids, and should not be mixed. It should not be stored for a long time to avoid deterioration. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
