Hazard Overview
sodium sulfite
Invasion pathway:
Health hazards: Irritating to eyes, skin, and mucous membranes.
Environmental hazards: Harmful to the environment and can cause pollution to water bodies.
Explosive hazard: This product is non flammable and has irritant properties.
First aid measures
Skin contact: Remove contaminated clothing and rinse with plenty of flowing water.
Eye contact: Lift the eyelids and rinse with flowing water or physiological saline. Seek medical attention.
Inhalation: Remove from the scene to a place with fresh air. If breathing is difficult, administer oxygen. Seek medical attention.
Ingestion: Drink plenty of warm water to induce vomiting. Seek medical attention.
Fire Protection Measures
Hazardous characteristics: There are no special combustion and explosion characteristics. Toxic sulfide smoke is generated due to high thermal decomposition.
Harmful combustion products: sulfides.
Fire extinguishing method: Firefighters must wear full body fire and gas resistant clothing and extinguish the fire upwind. When extinguishing a fire, try to move the container from the fire to an open area as much as possible.
Emergency Response for Leakage
Emergency response: Isolate the contaminated area and restrict entry and exit. It is recommended that emergency personnel wear dust masks (full face masks) and gas protective clothing. Avoid dust, sweep carefully, place in a bag and transfer to a safe place. It is also possible to rinse with a large amount of water, dilute the washing water and put it into the wastewater system. If there is a large amount of leakage, cover it with plastic cloth or canvas. Collect, recycle or transport to waste disposal sites for disposal.
Operation, Disposal and Storage
Operation precautions: Close the operation and strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, work clothes to prevent toxin penetration, and rubber gloves. Avoid generating dust. Avoid contact with acids. Light loading and unloading during transportation to prevent packaging damage. Equipped with leakage emergency response equipment. Empty containers may have residual harmful substances.
Storage precautions: Store in a cool and ventilated warehouse. Stay away from sparks and heat sources. It should be stored separately from acids and should not be stored together. Not suitable for long-term storage. The storage area should be equipped with appropriate materials to contain leaked materials.
Exposure Control/Personal Protection
Occupational exposure limits
China MAC (mg/m3): No standard established
Former Soviet MAC (mg/m3): 0.2
TLVTN: No standard established
TLVWN: No standard established
Monitoring method:
Engineering control: The production process is sealed and ventilation is strengthened.
Respiratory protection: When the concentration of dust in the air exceeds the standard, a self-priming filter type dust mask must be worn. During emergency rescue or evacuation, air respirators should be worn.
Eye protection: Wear chemical safety goggles.
Body protection: Wear work clothes that prevent the penetration of toxins.
Hand protection: Wear rubber gloves.
Other protective measures: Change and wash work clothes in a timely manner. Maintain good hygiene habits.
