Inhalation: May cause a red, dry, sore throat.
Ingestion: No acute or chronic health effects recorded.
Skin: May cause redness and inflammation.
Eye: May cause redness, itching and watering.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting; seek medical attention. Never induce vomiting or give
anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention
if symptoms persist.
