Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use alcohol foam, dry chemical or carbon dioxide.
Moderate fire hazard, when exposed to heat, flame or oxidizers.
Nausea, vomiting and diarrhea are possible if ingested.
Cough, tachypnea, and wheezing are common after inhalation.
Redness, swelling and pain may occur.
Irritants may cause swelling, redness and pain at any site, especially at mucous membranes. The mouth, nose, and eyes are susceptible to these effects.
Do NOT induce vomiting. Allow the victim to rinse his mouth and then to drink 2-4 cupfuls of water, and seek medical advice.
Remove from exposure to fresh air immediately.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
