Section 4 - FIRST AID MEASURES
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.
Notes to Physician:
Antidote: None reported.

Section 5 - FIRE FIGHTING MEASURES
General Information:
Evacuate area and fight fire from a safe distance. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear.
Material can spontaneously ignite (pyrophoric) when exposed to air at normal or slightly elevated temperatures. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. May re-ignite after fire is extinguished. Finely divided dusts may exhibit pyrophoric tendancies.
Extinguishing Media:
Use dry chemical. Contact professional fire-fighters immediately.
