first-aid
【Ingestion】 Do not induce vomiting. If the victim is sober and alert, give 2-4 cupfuls, milk or water. Do not give anything to people who are in a comatose state. Get medical assistance.
[Inhalation] From the scene to the fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical assistance. Do not use mouth-to-mouth breathing.
[Skin] Get medical assistance. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
【Eyes】 Rinse with plenty of water for at least 15 minutes. Rinse the eyes, lifting the upper and lower eyelids from time to time. Get medical assistance.
deal with
[Treatment] Wash thoroughly after operation. Take off contaminated clothing and wash it before reuse. Use only in well ventilated areas. Avoid contact with eyes, skin and clothing. Product residues (liquid and / or vapor) remain in empty containers and may be dangerous. Keep container tightly closed. Avoid contact with heat sources, sparks and flames. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, weld, drill, grind, empty containers or expose to heat, sparks or open flames.
Hazard identification
[Inhalation] Causes respiratory tract irritation. May cause similar effects as described for ingestion. Inhalation may cause pulmonary edema. Inhalation at high concentrations may cause depression and asphixiation of the CNS.
[Skin] Causes skin irritation. May be absorbed through the skin. If absorbed, ingestion causes similar symptoms. May cause cyanosis of limbs.
【Eyes】 Causes eye irritation. May cause chemical conjunctivitis and corneal damage.
【Ingestion】 May cause gastrointestinal irritation, nausea, vomiting and diarrhea. May cause liver damage. May cause depression in the central nervous system, characterized by excitement, headache, dizziness, drowsiness, and nausea. In the advanced stage, it may cause collapse, unconsciousness, coma, and death due to respiratory failure. May cause auditory and visual hallucinations, disorientation, sweating, and

[Fire extinguishing] Self-contained breathing apparatus, MSHA / NIOSH (or equivalent) and full-body protective clothing are required under pressure. In the event of a fire, irritating and highly toxic gases may be generated by thermal decomposition or burning. Use water spray to cool containers exposed to fire. Flammable liquid. To extinguish the fire, use water, dry powder, chemical foam, and alcohol-resistant foam. Use water spray to cool containers exposed to fire. Use foam, dry powder or carbon dioxide.
[On EXP. Limit] 11.5
[Under EXP. Limit] 1.7
[Fire hazard] This chemical is flammable.
Accidental leakage treatment measures
[Small leakage / leakage] Absorb leakage with inert materials (for example, dry sand or mud), and then place the chemical waste container. Avoid runoff flowing into sewers and ditches. Clean up the leak immediately and use appropriate protective equipment. Remove all sources of ignition. Use non-spark explosion-proof tools. Provide good ventilation.
