<br />Other Personal Protective
<br />Avoid accumulation and dispersion of dust to reduce explosion potential. Wear an impermeable apron
<br />Equipment:
<br />and boots. Locate safety shower and eyewash station close to chemical handling area. Take all
<br />precautions to avoid personal contact. Clothing and footwear that is fire retardant and dissipates static
<br />electrical charges should be worn when handling flammable materials. Natural fibers (cotton, wool,
<br />leather and linen) should be selected in favour of synthetic materials (rayon, nylon and polyester).
<br />Skin Notation: Contact with skin, eyes and mucous membranes can contribute to the overall exposure
<br />and may invalidate the TLV. Consider measures to prevent absorption by these routes.

<br />CHEMICAL STABILITY
<br />...a.. . . =t.+. =e'-_... .... .: sa:+,-
<br />Under Normal Conditions:
<br />Unstable. Solid Xanthates are stable when kept cool and dry. Exposure to heat causes decomposition.
<br />Acids and oxidizing agents accelerate aging. In solution, Xanthates will decompose slowly even at room
<br />temperature. (3)
<br />Under Fire Conditions:
<br />Flammable. This product may be capable of forming flammable dust clouds in air.
<br />Hazardous Polymerization:
<br />Will not occur.
<br />Conditions to Avoid:
<br />High temperatures, sparks, open flames and all other sources of ignition. Avoid accumulation and
<br />dispersion of dust to reduce explosion potential. Exposure to heat and moisture may cause the
<br />decomposition of xanthates to release flammable, explosive and poisonous Carbon Bisulphide vapours.
<br />(3)
<br />Materials to Avoid:
<br />Strong oxidizers. Lewis or mineral acids. Metal Salts. Copper and its alloys.. Contact with acids will
<br />liberate Carbon Bisulphide. Avoid moisture contamination. Contact with water or moisture will liberate
<br />Carbon Bisulphide. Mixtures or reactions of alcohols with the following materials may cause explosions:
<br />barium perchlorate, chlorine, hypochlorous acid, ethylene oxide, hexamethylene diisocyanate and other
<br />isocyanates, nitrogen tetroxide, permonosulfuric acid and tri- isobutyl aluminum. (4) Attacks some types
<br />of rubber, plastics and coatings.
