SECTION 2: Hazards identification

OSHA Skin Contact: Prolonged contact can cause reddening, swelling, rash, scaling or blistering. In those who have developed a skin sensitiza- tion, these symptoms can develop as a result of a very small amount of liquid material or vapors. Eye Contact: Liquid, vapors, or mist are irritating to the eyes and can cause tearing, stinging, burning, redding or swelling. If left un- treated, corneal damage can occur and injury is slow to heal. Damage is usually reversible. Ingestion: Ingestion could result in irritation and corrosive action in the mouth, stomach tissue and digestive tract. These irritations would be followed by vomiting and cramps. Inhalation: Inhalation of vapors or mist may cause respiratory irritation (nose, throat, lungs). Chronic inhalation can result in sensitization.

Precautionary statements

Do not handle until all safety precautions have been read and understood. Do not breathe vapors. In case of inadequate ventilation wear respiratory protection. Wear protective gloves and eye protection. Do not eat, drink or smoke when using this product. Wash thoroughly after handling. Store locked up. Keep away from children. Dispose of contents and container in accordance with applicable local, regional and national regulations.

Signal word

DANGER

Hazard statements

Chronic As a result of previous repeated overexposure or a single large dose, certain individuals develop isocyanine sensitization (chemical asthma) or tissue injury in the upper respiratory tract. Animal tests indicate skin contact alone may also lead to allergic respiratory reaction. These effects may be permanent. Any person developing asthmatic reaction or other sensitization should be removed from further exposure.

Potential health effects

At room temperature, MDI vapors are minimal due to low vapor pressure. However, heating, foaming or otherwise dispers- ing (drumming, venting or pumping) operations may generate more vapor or aerosol concentrations of isocyanate. Excessive exposure may cause irritation of the eyes, upper respiratory tract and lungs. Severe overexposure may lead to pulmonary edema. Respiratory sensitization with asthma like symptoms may occur in susceptible individuals. MDI concentration below the exposure guidelines may cause allergic respiratory reactions in individuals already sensitized. Symptoms may include coughing, dryness of throat, headache, nausea, difficulty breathing and feeling of tightness in the chest. Effects may be delayed. Impaired lung function (decreased ventilators capacity) has been associated with overexposure to isocyanate. Persons With Known Respiratory or Allergy Problems Must Not Be Exposed to This Product.

Lung tumors have been observed in laboratory animals exposed to aerosol droplets of MDI/Polymeric MDI (6mg/ m3) for their lifetime. Tumors occurred concurrently with respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these effects. Warning Our products may contain trace amounts of some chemicals considered by the State of California to be carcinogens or reproductive toxicants.
