Hazard statements

Danger High inhalation hazard – allergic sensitizer. Severe skin irritant; allergic sensitizer. Severe Eye irritant. Moderate ingestion hazard. Irritating to gastrointestinal tract. Mucous membrane irritant. Prolonged exposure may cause allergic sensitization. Prolonged or repeated exposure to vapors may cause lung damage.

Principle Routes of Exposure

Eye Contact, Inhalation, Skin Contact

Medical Conditions Generally Aggravated by Exposure

Skin disorders, Respiratory disorders, Eye disorders, Allergies Signs and Symptoms of Acute Exposure: High Health Hazard. Hexane, 1,6-diisocyanato- High inhalation hazard – allergic sensitizer. Skin sensitizer. Homopolymer Moderate skin irritant. Hexane, 1,6-diisocyanato- Respiratory sensitizer. Inhalation irritation. Severe skin Irritant; allergic sensitizer. Severe eye irritant. Skin: This material is a severe skin irritant. Causes irritation seen as local redness and possible swelling. Repeated or prolonged skin contact may cause sensitization andan allergic skin reaction. Inhalation: Inhalation would be expected to cause irritation of the nose, mouth, throat and lungs. Inhalation may cause asthma-like symptoms, including coughing, wheezing, tightness of chest, shortness of breath, and headache. Eye: May result in severe irritation and possible damage to the cornea and impairment of vision. The effects of high vapor concentration may vary from slight irritation (with tearing and a burning sensation) to keratitis (Inflammation of the cornea) and impairment of vision. Ingestion: Ingestion not a likely route of exposure. Ingestion may result in irritation of the mouth and digestive tract. Gastroenteritis may result with any or all of the following symptoms: nausea, vomiting, diarrhea, headache.

Potential chronic health

Prolonged or repeated exposure to vapors may cause lung damage. Repeated over exposure to isocyanates and high one time accidental exposures have been associated with gradual decrease in lung function. Repeated inhalation also may cause allergic sensitization of the respiratory tract, resulting in coughing, wheezing, shortness of breath, chest tightness, and other asthma-like symptoms that may be life-threatening. Repeated skin contact may cause irritation and allergic dermatitis. Hexane, 1,6-diisocyanato- Hexane diisocyanate homopolymer is a skin and respiratory Allergic Homopolymer sensitizer. Sensitive individuals may exhibit skin rash, wheezing, tightness of the chest, and difficulty breathing that may progress to a life-threatening inability to breathe. Chronic inhalation may cause lung damage. Hexane, 1,6-diisocyanato- Hexane diisocyanate (HDI) is a potent skin and respiratory allergic sensitizer. Sensitive individuals may exhibit skin rash, wheezing, tightness of the chest, and difficulty in breathing that may progress to a life-threatening inability to breathe. Chronic inhalation may cause lung damage. Conditions Aggravated By Exposure: History or presence of allergic disease. Exposure may aggravate one or more of the following medical conditions: Asthma or asthmatic bronchitic medical history.
