SECTION 2: Hazards identification

EMERGENCY OVERVIEW WARNING! No Physical Hazards Color Yellow to Brown Odor Slight Odor May cause mechanical irritation to the eyes, skin and respiratory tract. May cause allergic respiratory reaction. May cause allergic skin reaction. Toxic gases/fumes are given off during burning or thermal decomposition and may cause allergic skin and respiratory reaction. Melted product is flammable and produces intense heat and dense smoke during burning.

Principle Routes of Exposure

Inhalation, Skin Contact, Eye Contact HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE Inhalation Hazards Acute Inhalation Hazards: Isocyanate vapors or mist can irritate (burning sensation) the mucous membranes in the respiratory tract (nose, throat, lungs) causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function (breathing obstruction). Persons with a preexisting, nonspecific bronchial hyperreactivity can respond to concentrations below the exposure limit with similar symptoms as well as asthma attack. Exposure to high vapor concentrations may lead to bronchitis, bronchial spasm and pulmonary edema (fluid in lungs). These effects are usually reversible. Chemical or hypersensitive pneumonitis, with flu-like symptoms (e.g., fever, chills) has also been reported. These symptoms can be delayed up to several hours after exposure. Chronic Inhalation Hazards: As a result of previous repeated overexposures or a single large dose, certain individuals may develop isocyanate sensitization (chemical asthma) which will cause them to react to a later exposure to isocyanate at levels well below the suggested exposure limit. These symptoms, which can include chest tightness, wheezing, cough, shortness of breath or asthma attack, could be immediate or delayed (up to several hours after exposure). Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon exposure to dust, cold air or other irritants. This increased lung sensitivity can persist for weeks and in severe cases for several years. Overexposure to isocyanates has also been reported to cause lung damage (including decrease in lung function) which may be permanent. Sensitization can either be temporary or permanent. Skin Hazards Acute Skin Hazards: Isocyanates react with skin protein and moisture and can cause irritation which may include the following symptoms: reddening, swelling, rash, scaling, or blistering. Chronic Skin Hazards: Prolonged contact can cause reddening, swelling, rash, scaling, blistering, and in some cases, skin sensitization. Individuals who Material Name: STABAXOL P 66D Article Number: 407880 2 of 10 have skin sensitization can develop these symptoms from contact with liquid or vapors. Eye Hazards Acute Eye Hazards: Isocyanate vapors are irritating and can cause tearing, reddening and swelling. If left untreated, corneal damage can occur and injury is slow to heal. However, damage is usually reversible. Chronic Eye Hazards: None reported for the product. Ingestion Hazards Acute Ingestion Hazards: Ingestion of isocyanates can result in irritation of the mouth, stomach tissue and digestive tract. Symptoms can include sore throat, abdominal pain, nausea, vomiting and diarrhea. Chronic Ingestion Hazards: None reported Carcinogenic Components: NTP: None IARC: None OSHA: None

Medical Conditions Generally Aggravated by Exposure

May aggravate existing eye, skin or respiratory conditions.

Potential health effects

PRODUCT AS A WHOLE: Mechanical irritation can be produced Postnote: if this product is introduced into the eye. Small quantities of isocyanates, DIPPI and TRIDI, may be released when drums are opened for the first time. Air sampling on similar products has shown these levels to be below the suggested exposure limit. In addition, if this material is heated above 350 F (177 C) (i.e. during thermal processing), DIPPI and TRIDI vapors may be generated. Results from air-sampling on similar products show that DIPPI and TRIDI concentrations which exceed the suggested exposure limit may be present during thermal processing. The following effects reflect the potential health hazards associated with overexposure to isocyanates in general.
