SECTION III – HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW: There are no significant health hazards associated with exposure to this product. Fabrication: The product is a solid sheet material. Cutting and fabricating activities utilizing impact or power equipment may release small chips or shards, which are a hazard to the eyes. Grinding and sanding operations may release small quantities of dust with particles generally larger than respirable size. Burning: Toxic gases and fumes are given off during burning or thermal decomposition. Burning produces intense heat and dense smoke. SIGNS AND SYMPTOMS OF OVEREXPOSURE: Overexposure to this product is not likely to cause any significant acute effect. HMIS RATING: Health: 0 Fire: 1 Physical Hazard: 0 Personal Protection: B POTENTIAL HEALTH EFFECTS: ROUTES OF ENTRY: Eyes, Inhalation ACUTE EFFECTS: Coarse dust and particulate generated during fabrication can irritate eyes, nasal passages, and the upper respiratory system. CHRONIC EFFECTS: Chronic effects are unlikely. MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Chronic respiratory disease. CARCINOGENICITY: This product is not classified or regulated by NTP, IARC, or OSHA.

SECTION IV – FIRST AID MEASURES

EYE CONTACT: To remove particulate matter, flush with large amounts of water until irritation subsides. See a physician if irritation persists. INHALATION: Blow nose and rinse mouth with water to clear dust and particulate. If exposed to excessive levels of dust or fumes, remove to fresh air and get medical attention if cough or other symptoms develop.

SECTION V – FIRE FIGHTING MEASURES

NFPA RATING: Health: 0 Fire: 1 Reactivity: 0 Other: — FLASH POINT AND METHOD: Not applicable. EXTINGUISHING METHOD: Water spray and foam. Carbon dioxide and dry chemical may permit re-ignition due to lack of cooling capacity. NFPA FIRE FIGHTING PROCEDURES: Use water spray or foam applied from a safe distance to avoid exposure to hazardous vapors and other decomposition products. FIRE OR EXPLOSION HAZARDS: Product is a combustible thermoplastic resin. Because of the potential for dense smoke in a fire situation, fire fighters should wear approved self-contained breathing apparatus. Dust from secondary fabrication operations may form explosive mixtures in air. Consequently, storage bins and dust collectors should be adequately grounded and vented. HARMFUL COMBUSTION PRODUCTS: Intense heat, smoke, irritating toxic gases, and aerosols, including carbon dioxide, carbon monoxide, methyl methacrylate and hydrocarbon fragments, may be generated by thermal decomposition when the product undergoes combustion.

SECTION VI – ACCIDENTAL RELEASE MEASURES

SPILL OR LEAK PROCEDURES: Sweep or pick-up fabrication debris. Debris may usually be disposed of in a non-regulated landfill. However, prior to disposal, it is recommended that the regulations in effect for the particular area where disposal is to take place be checked to prevent improper disposal.

SECTION VII – HANDLING AND STORAGE

STORAGE TEMPERATURE: Store in well ventilated areas at temperatures below 120° F (49° C). SPECIAL SENSITIVITY: None HANDLING PRECAUTIONS: Use good housekeeping procedures to minimize the accumulation of dust during fabrication procedures. Keep open flames, sparks and heat away from all dusty operations.

SECTION VIII – EXPOSURE CONTROLS/PERSONAL PROTECTION

EYE PROTECTION: Wear safety glasses or face shields when cutting or machining. SKIN PROTECTION: Gloves are recommended when fabricating due to possible sharp edges. RESPIRATORY PROTECTION: For nuisance dust not otherwise regulated, observe the OSHA PEL of 15 mg/m3. When exposures over the PEL are encountered and engineering or other controls are not adequate to reduce airborne concentrations to below the PEL, use a dust mask such as 3M-8710 or equivalent.

SECTION IX – PHYSICAL AND CHEMICAL PROPERTIES

PRODUCT USES: Fabricated sheet items including glazing, display components, machine covers, and safety shields. PHYSICAL FORM: Clear or tinted thermoplastic sheet. SPECIFIC GRAVITY: 1.2 MELTING POINT: 428° – 446° F (220° – 230° C) SOFTENING POINT: 302° – 320° F (150° – 160° C)

SECTION X – REACTIVITY

STABILITY: Product is stable under normal conditions. HAZARDOUS POLYMERIZATION: Will not occur. INCOMPATIBILITIES: None in designed use. DECOMPOSITION PRODUCTS: Burning or thermal decomposition may generate carbon monoxide, carbon dioxide, bisphenol A, diphenyl carbonate, phenol and phenol derivatives. Trace amounts of aliphatic and aromatic hydrocarbons, aldehydes, acids, and nitrogen oxide compounds may also be formed. CONDITIONS TO AVOID: Exposure to high temperatures and direct flame.
