SECTION 4: First aid measures
4.1 Description of first aid measures
First-aid measures after inhalation
If this chemical has been inhaled, remove the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the person warm and at rest.
First-aid measures after skin contact
If this chemical contacts the skin, immediately wash the contaminated skin with soap and water. If this chemical penetrates the clothing, immediately remove the clothing, wash the skin with soap and water, and get medical attention promptly.
First-aid measures after eye contact
If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.
First-aid measures after ingestion
If this chemical has been swallowed, get medical attention immediately.

Symptoms of exposure may include headache, dizziness, nausea, vomiting, and respiratory distress.
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.
