Section 3: Hazard Identification

Emergency overview:
Severe eye irritant; skin irritant; respiratory tract irritant;
harmful if swallowed

Appearance: white, crystalline

Flash Point: 356° F
 
Target Organs: Eyes, skin, respiratory system

Potential Health Effects

Eye: Severe eye irritant – may cause burns.

Section 4: First Aid Measures

Eyes: In case of eye contact, immediately flush eyes with
copious amounts of water for at least 15 minutes, holding eyelids
open. Seek immediate medical attention.

Skin: In case of skin contact, flush skin with copious amounts
of water for at least 15 minutes.  If irritation occurs and persists,
seek medical attention.

Ingestion: If swallowed, give 8 ounces of water or milk, if
conscious and alert.  Never give anything by mouth to an unconscious
person.  Do not induce vomiting. Seek immediate medical attention.
