Specification
First Aid Measures of 1,1,1-Trifluoropropene (677-21-4):
1.Ingestion: Seek medical assistance.
2.Inhalation: Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
3.Skin: Remove and isolate contaminated clothing and shoes. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water
4.Eyes: Flush with running water for at least 20 minutes
Hazards Identification of 1,1,1-Trifluoropropene (677-21-4):
1.Inhalation: Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations.
2.Skin: Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
3.Eyes: May cause irritation.
4.Hazards: Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Containers may explode when heated.
