3. HAZARDS IDENTIFICATION

Most important Hazard Irritating to eyes.

Emergency Overview: Odorless, colorless translucent crystals with

strong acidic taste. Citric acid is a skin and mucous membrane irritant

and an eye irritant. It may cause allergic reactions in some

individuals.



Potential Health Effects:

Inhalation: May cause mucous membrane irritation with sore throat,

coughing and shortness of breath.

Eye contact: May cause irritation with redness, pain, possible eye

burns, conjunctivitis, ulceration and permanent cloudiness.

Skin contact: May cause irritation with swelling, redness and pain.

Ingestion: May cause acute gastrointestinal irritation with abdominal

pain.



Chronic: Repeated or prolonged skin contact may result in dermatitis.

Prolonged or repeated eye contact may result in conjunctivitis. Long

term oral overexposure may cause damage to tooth enamel.



Carcinogen status:   None



4. FIRST AID MEASURES

General advice Consult a physician.

Major effects of exposure: Irritating to eyes and skin.

Inhalation: Move to fresh air.

Skin contact: Wash off immediately with soap and plenty of water.
