SECTION 4: First aid measures
4.1 Description of first aid measures
First-aid measures after inhalation
Move to fresh air. If breathing is difficult, give oxygen. Seek medical attention if symptoms persist.
First-aid measures after skin contact
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water.
First-aid measures after eye contact
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.
First-aid measures after ingestion
Do not induce vomiting. Rinse mouth and seek medical attention.
4.2 Most important symptoms and effects, both acute and delayed
Symptoms relating to use
Cough, shortness of breath, and irritation of the respiratory tract.
4.3 Indication of any immediate medical attention and special treatment needed
General information
Treat symptomatically. Show this safety data sheet to the treating physician.
SECTION 5: Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water.
Unsuitable extinguishing media
Not specified
