SECTION 2: Hazards identification

OSHA Classification of the Substance or Mixture QPAC" 25 is composed of no less than 94% Poly(ethylene carbonate) polymer and contains less than 1% (between 0.2%-l),8%) methylene chloride and less than 5% ethylene carbonate Methylene chloride is GHSA classified as H351: “Suspected of causing cancer” in accordance with

Hazard statements

Skin Irritation: H315 Causes skin irritation Eye Irritation: H319 Causes serious eye irritation.

2.3 Other hazards

Avoid contact with strong oxidizing agents, Avoid temperatures above 150°C. At process temperatures irritating fumes may be produced. Hazardous Decomposition Products: Ethylene carbonate when bumed may form toxic levels of carbon monoxide, carbon dioxide, irritating aldehydes, acids and ketones, Other hazardous products may occur under conditions of decomposition or combustion, and’or result from interaction with other materials and/or environment of decomposition or combustion. Molten polymer may cause thermal bums. Slipping hazard if spilled on hard smooth walking surface. The material may accumulate static charges, which could be a source of ignition. Emergency Overview Avoid contact with eyes, skin or clothing, Avoid breathing dust or vapor from granulates or powder. Do not swallow, Wear safety glasses and latex gloves. Wash thoroughly after handling. Use with adequate ventilation. May produce hazardous gases under fire conditions, During emergencies, wear equipment to protect eves, skin, and respiratory tract. Prevent material and run-off from entering sewer or waterways. Consult the Safety Data Sheet. Empower Materials QPAC* 25 Paye 2 of 10 Conditions aggravated by exposure No human or animal health effects data are known to exist. However, available toxicity information on polymers of molecular weight 1000 or greater suggests they have low toxicity. May contain 0.2 0.8% methylene chloride, Pure methylene chloride is a suspected buman carcinogen,

2.1 Classification of the substance or mixture

QPAC" 25 is composed of no less than 94% Poly(ethylene carbonate) polymer and contains less than 1% (between 0.2%-l),8%) methylene chloride and less than 5% ethylene carbonate. Methylene chloride is GHSA classified as H351: “Suspected of causing cancer” in accordance with 29 CER [910.1200 Appendix A (OSHA HCS) Carcinogenicity (methylene chloride: Category 2) Ethylene carbonate is GHS classified as H315: “Causes skin trritarion” in accordance with 29 CFR 1910.1200 Appendix A (OSHA HCS) Skin Imitation (Ethylene carbonate: Category 2) Ethylene carbonate is GHS classified as H319: “Causes serious eye irritation” in accordance with 29 CER [910.1200 Appendix A (OSHA HCS) Eye ritation (Ethylene carbonate: Category 2A) Exposure limits of pure Methylene Chloride: Refer to the OSHA Methylene Chloride Standard [OSHA3144-06R (2003): sets a permissible exposure limit (PEL) of 25 parts methylene chloride per million parts of air (ppm) as an eight-hour time-weighted average (TWA). This refers to the average exposure during an eight-hour period. Employers must use engineering and work practice controls to limit employee exposures. Respiratory protection must be used in addition if these controls are insufficient to reduce exposures to below the limits. The action level for airborne methylene chloride is set at a concentration of 12.5 ppm, calculated as an eight-hour TWA. Reaching or exceeding the action level signals that employers must begin compliance activities such as exposure monitoring and medical surveillance. There is also a shott- term exposure limit (STEL) of 125 ppm, as measured over a [S-minute period.
