SECTION 2: Hazards identification

Emergency Overview

Appearance/Odor

Tan to brown liquid in pre-pressurized container. Slight musty odor Product reacts with water releasing carbon dioxide. Diphenylmethane diisocyanate (MDI) may polymerize at temperatures above 204°C/400°F and cause pressure build-up and possible explosion of closed containers. Containers near fire or other heat sources should be cooled with water spray to avoid pressure build-up. HMIS: Health = 2 Fire = 1 Reactivity = 1

Potential health effects

Summary Exposure to vapors from this product may be irritating to the eyes, respiratory passages, and mucous membranes. MDI is a strong sensitizer. Inhalation of mists or skin or eye contact may result in irritation and sensitization (allergy). Inhalation May cause allergic respiratory reaction and lung injury. MDI concentrations below the exposure guidelines may cause allergic respiratory reactions in individuals already sensitized. Symptoms may include coughing, difficult breathing, and a feeling of tightness in the chest. Effects may be delayed. Decreased lung function has been associated with overexposure to isocyantes. Skin Contact with this product may cause skin irritation. May stain skin. Absorption A single prolonged exposure is not likely to result in the material being absorbed in harmful amounts. Ingestion This product is not intended to be ingested or eaten under normal conditions of use. If ingested, it may cause irritation and corrosive effects to the gastrointestinal (digestive) tract. Single dose oral toxicity is considered to be low. No hazards anticipated from swallowing small amounts incidental to normal handling operations. Eyes Immediate irritation (itching) or redness may occur. Materials containing MDI may react with moisture of the eye, forming a thick material which may be difficult to wash from the eye. Ears Contact with this product may cause skin irritation. May stain skin.

Principle Routes of Exposure

Exposure) Inhalation (breathing), skin, and eye contact. Target Organs Respiratory system, skin, and eye.

Medical Conditions Generally Aggravated by Exposure

Pre-existing respiratory diseases or conditions, especially asthma or chemically-induced asthma. Prior exposure and sensitization to isocyanate, or other chemical sensitizers may cause asthmatic, or allergic reactions.
