Specification
N-Butyl Thiocyanate (CAS NO.628-83-1) is a eliminate the stink colorless liquid, insoluble in water, but soluble in alcohol, ether immiscibility,it is an organic drugs.
First Aid Measures:
Ingestion: Seek medical assistance.
Inhalation: Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Skin: Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
Eyes: Immediately flush with running water for at least 20 minutes.
Fire Fighting Measures:
Fire Fighting: Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Dry chemical, carbon dioxide, alcohol-resistant foam or water spray.
Fire Potential: Combustible material: may burn but does not ignite readily.
