SECTION 2: Hazards identification

3.1. EMERGENCY OVERVIEW 3.1.1. This product consists primarily of high molecular weight polymers which are not expected to be hazardous. 3.1.2. Can burn in a fire creating dense, toxic smoke. 3.1.3. Molten plastic can cause severe burns. 3.1.4. Odorless. 3.1.5. No significant immediate hazards for emergency response are known. 3.2.

Potential health effects

See Section 11 for toxicological data.) 3.2.1. EYE: Solid or dust may cause irritation or corneal injury due to mechanical action. Elevated temperatures may generate vapor levels sufficient to cause eye irritation. 3.2.2. SKIN: Essentially nonirritating to skin. Mechanical injury only. Molten material may burn skin. Skin absorption is unlikely due to physical properties. 3.2.3. INGESTION: Single dose oral toxicity is considered to be extremely low. No hazards anticipated from swallowing small amounts incidental to normal handling operations. 3.3. INHALATION: Dust may cause irritation of the upper respiratory tract. At room temperature, Exposure to vapors is unlikely due to physical properties: normal-processing temperatures may generate vapors which may cause irritation if ventilation is inadequate. 3.4. SYSTEMIC (OTHER TARGET ORGAN) Effects: No specific data: however, repeated exposure to the unheated material are not anticipated to cause significant adverse effects. Processing fumes may cause eye and respiratory irritation upon repeated exposure. 3.5.
