Signal word

CAUTION! Physical Health Hazards: Dust may be irritating to body tissues after prolonged contact, and inhalation of the dust can cause irritation to the nose and throat and coughing. It may also cause acute allergic reaction in some people. Physical state: Solid Color: White crystalline powder Odor: None Odor threshold: No data available

Principle Routes of Exposure

Eye contact, ingestion, skin contact Signs and Symptoms of Acute Exposure: Severe coughing and/or skin irritation. Skin contact: Brief contact with the powder should not, in most cases cause irritation. However prolonged contact can cause irritation. When contact occurs, the powder should be washed off with soap and water. Brief contact with an aqueous solution of the powder should not, in most cases, cause irritation. Should contact with the aqueous solution occur, wash with soap and water. Steady, constant contact with skin in an aqueous solution should be avoided. Inhalation: Inhalation of the powder will cause irritation to the nose and throat and cause coughing and eventually chest discomfort. However, some individuals may be very allergic to this material. In the case of inhalation of the powder and dust, remove to fresh air immediately. Give artificial respiration if not breathing. Get immediate medical attention. Eye contact: Immediately start flushing with an excess of running water for at least 15 minutes, lifting the upper and lower lids occasionally. Get immediate medical attention for the eyes in such cases. Ingestion: Ingestion is unlikely. However, should ingestion occur, give the victim 8-12 ounces of water and seek medical attention. If person is unconscious, remove any visible residue from mouth and seek medical attention. Note: Never give anything by mouth to an unconscious person.

Potential chronic health

Summary Inhalation: Long term breathing of the dust can cause irritation to the nose and throat and eventually lead to coughing. Skin Contact: Long term exposure to the dry powder of aqueous solutions formed from the dry powder will eventually lead to skin irritation. Conditions Aggravated by Exposure: Some persons may be very allergic to this material.
