Part Three: Overview of Dangerous Goods
Hazard category: Invasion route: Inhalation, invasion, transdermal absorption Health hazard: Mild irritation to eyes and upper respiratory tract. Continuous inhalation can cause dizziness, nausea, drowsiness, and other symptoms of paralysis. Liquid contamination of the skin can cause itching. Environmental hazards: May pose a threat to the environment. Explosive hazard: This product is flammable, low toxic, and irritating.
Part Four: First Aid Measures
Skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and water. Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention. Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
Part 5: Fire Protection Measures
Dangerous characteristics: Its vapor and air can form explosive mixtures, which are highly flammable and explosive when exposed to open flames and high heat. Reacts violently when in contact with oxidants. Excessive flow rate can easily generate and accumulate static electricity. Its vapor is heavier than air and can spread to a considerable distance at lower places. When it comes into contact with a fire source, it will
Ignite and reignite. If exposed to high heat, the pressure inside the container increases, posing a risk of cracking and explosion. Harmful combustion products: carbon monoxide, carbon dioxide. Fire extinguishing method: Firefighters must wear gas masks and full body firefighting suits, and extinguish the fire in the upwind direction. Try to move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: fog water, foam, dry powder, carbon dioxide, sand. Not suitable for using water.
Part 6: Emergency Response for Leakage
Emergency action: Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb with activated carbon or other inert materials. It can also be brushed with lotion made of incombustible dispersant, and the washing solution is diluted and discharged into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Cover with foam to reduce steam disaster. Transfer to a tanker or dedicated collector using an explosion-proof pump, and recycle or transport to a waste disposal site for disposal.
Part 7: Handling and Storage
Precautions for operation: Closed operation, local exhaust. Prevent steam leakage into the workplace air. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type gas masks (half face masks), chemical safety goggles, anti-static work clothes, and rubber gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Welding, cutting, and other operations cannot be carried out before removing liquids and vapors. Avoid generating smoke. Avoid contact with oxidants. Containers and conveying equipment should be grounded to prevent static electricity. During filling, the flow rate should be controlled and there should be a grounding device to prevent static electricity accumulation. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances. Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. Protect from direct sunlight. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants and edible chemicals, and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.
Part 8: Contact Control/Personal Protection
Engineering control: Closed operation, local exhaust. Respiratory protection: When the concentration in the air exceeds the standard, a self-priming filter type gas mask (half face mask) must be worn. During emergency rescue or evacuation, air respirators should be worn. Eye protection: Wear chemical safety goggles. Body protection: Wear anti-static work clothes. Hand protection: Wear benzene resistant and oil resistant gloves. Other protections: Smoking, eating, and drinking are prohibited in the workplace, and hands should be washed before meals. After work, take a shower and change clothes. Maintain good hygiene habits.
Part 8: Exposure control/individual prevention and control Maximum allowable concentration: China MAC: -- Maximum allowable concentration: former Soviet Union MAC: 500 Monitoring method: Engineering control: Production process is closed and fully ventilated. Provide safety shower and eye wash equipment. Respiratory protection: When the concentration in the air is high, wear a filtered gas mask (half face mask). Eye protection: Wear safety goggles. Body protection: Wear anti-static work clothes. Hand protection: Wear rubber oil resistant gloves. Other protections: Smoking is strictly prohibited at the work site. Avoid long-term repeated exposure.
