However, avoid temperatures above 260C/500F for prolonged <br /> periods to prevent slow decomposition <br /> Hazardous Decomposition Products: Thermal decomposition may yield acrylic monomers <br /> II—sirdous Polymerization: Product will not undergo polymerization <br /> Incompatibility: Avoid contact with acids, alkalies and strong oxidizing agents <br /> SPILL OR LEAK PROCEDURES <br /> Personal Protection: Wear gloves made of cotton, canvas or leather Additional personal protective equipment <br /> b,.,.. , Include safety glasses(ANSI 287.1 or approved equivalent) <br /> Procedures: Floor may be slippery; use care to avoid falling. Transfer spilled material to suitable containers for <br /> recovery or disposal. <br /> EXPOSURE CONTROLSIPERSONAL PROTECTION <br /> Exposure Limit Information: <br /> No, 1: Poly(Methyl methacrylate) <br /> COMPONENT OSHA ACG IH <br /> No. TWA STEL TWA STEL <br /> I None None None None <br /> Respiratory Protection: A respiratory protection program meeting OSHA 1910 134 and ANSI,286.2 <br /> requirements must be followed whenever workplace conditions warrant a respirator's use None required if <br /> airborne concentrations are maintained below the exposure limit listed in '.Exposure Limit Information'. <br /> Up to 10 times the TWA/TLV: Wear a MSHA/NIOSH approved (or equivalent)half-mask, air-purifying <br /> respirator <br /> Up to 1,000 ppm Organic Vapor: Wear a MSHA/NIOSH approved(or equivalent) full-facepiece, air-purifying <br /> rcJplrator. <br /> Above 1,000 ppm Orgainc Vapor or Unk_sown: Wear a MSHA/N10SH approved(or equivalent self-contained <br /> breathing apparatus in the positive pressure mode,or MSHA/NIOSH approved(or equivalent)full-facepiece airline <br /> respirator in the positive pressure mode with emergency escape provisions. <br /> Air-purifying respirators should be equipped with MSHA/NIOSH approved(or equivalent)cartridges for protection <br /> against organic vapors. <br /> Eve Protection: Use safety glasses(ANSI x87.l or approved equivalent) <br /> Hand Protection. Cotton,canvas or leather gloves <br /> Engineering Controls(Ventilation): Use local exhaust ventilation with a minimum capture velocity of 100 ft/min <br /> (0 Sm/sec)at the point of vapor evolution. Refer to the current edition of Industrial Ventilation A Ma un al of <br /> Recommended Practice published by the American Conference of Governmental industrial Hygientists for <br /> information on the design, installation, use and maintenance of exhaust systems. <br /> HANDLING AND STORAGE <br /> Storage Conditions: This material is not hazardous under normal storage conditions However, all materials of <br /> this type release some monomer vapors or gases when stored for prolonged periods at elevated temperatures <br /> Avoid temperature extremes during storage:ambient temperature preferred. <br /> Handling Procedures: This material can release monomer vapors or gases when heated to high temperatures <br /> during processing,cutting or machining. See Exposure Controls/Petsonal Protection for types of ventilation <br /> required. <br /> (D <br />
