Hazard category:
Invasion route: health hazard: this product has irritating effect on skin. Steam or fog can irritate eyes, mucous membranes and upper respiratory tract. The oral LD of this product for adults is close to 0.5g/kg；. ; Children's oral LD is 4ml. There are obvious gastrointestinal irritation symptoms, central nervous system symptoms, and oral high fever.
Environmental hazard: explosion hazard: this product is flammable, toxic and irritating.
Acute toxicity: 887 mg/kg (taken orally by rats); 2 100 mg/kg (dog by mouth); 700 mg/kg (taken orally by guinea pigs)
Skin contact: Take off contaminated clothes and rinse with running water.
Eye contact: Lift eyelids and rinse with running water or normal saline. See a doctor.
Inhalation: Leave the site and go to a place with fresh air. If you have difficulty breathing, give oxygen. See a doctor.
Intake: Drink enough warm water to induce vomiting. See a doctor.
Hazard characteristics: flammable in case of open fire and high heat. Decomposition at high temperature gives off irritating smoke.
Harmful combustion products: carbon monoxide and carbon dioxide.
Fire extinguishing method: Firefighters must wear gas masks and full-body fire protection suits to extinguish the fire in the upwind direction. Move the container from the fire to an empty place as much as possible. Spray water to keep the burning container cool until the fire goes out. If the container in the fire changes color or the safety pressure relief device sounds, it must be evacuated immediately. Extinguishing agent: atomized water, foam, dry powder, carbon dioxide, sand.
Emergency treatment: quickly evacuate the personnel in the leaked and polluted area to a safe area, isolate them, and strictly restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off the leakage source as much as possible. Prevent it from flowing into confined spaces such as sewers and flood discharge ditches. Small amount of leakage: mixed with sand, dry lime or soda ash. You can also brush the emulsion made of incombustible dispersant, and dilute the emulsion and put it into the wastewater system. A large number of leaks: damming or digging holes to contain them. Pump it into a tank car or a special collector with a pump, and recycle it or transport it to a waste disposal site for treatment.
Precautions for operation: close the operation and strengthen ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear self-priming filter gas mask (half mask), chemical safety glasses, breathable work clothes and rubber oil-resistant gloves. Stay away from kindling and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Prevent the steam in the workplace from leaking into the air. Avoid contact with oxidants and alkalis. When handling, handle with care to prevent the packaging and containers from being damaged. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances behind.
Precautions for storage: Store in a cool and ventilated warehouse. Stay away from fire and heat sources. Should be stored separately from oxidants, alkalis and edible chemicals, and should not be mixed. Equipped with corresponding varieties and quantities of fire fighting equipment. The storage area should be equipped with emergency response equipment for leakage and suitable accommodation materials.
Engineering control: the production process is sealed and ventilation is strengthened.
Respiratory system protection: When the concentration in the air exceeds the standard, you must wear a self-priming filter gas mask (half mask). Air respirator should be worn during emergency rescue or evacuation.
Eye protection: Wear chemical safety glasses.
Physical protection: wear anti-virus infiltration overalls.
Hand protection: Wear rubber oil-resistant gloves.
Other protection: Smoking and eating are prohibited in the workplace. Take a shower and change clothes after work. Maintain good hygiene habits.
Disposal method of waste: refer to relevant national and local laws and regulations before disposal. Incineration is recommended.
Abandoned preventive measures:
Packing category: Z0 1
Precautions for transportation: check whether the packaging container is complete and sealed before transportation to ensure that the container does not leak, collapse, fall or be damaged during transportation. It is strictly prohibited to transport with oxidants, alkalis and edible chemicals. Transport vehicles and boats must be thoroughly cleaned and disinfected, otherwise other items may not be shipped. During shipment, the assembly position should be far away from the bedroom and kitchen, and isolated from the engine room, power supply, fire source and other parts. Highway transportation should follow the prescribed route.
