MATERIAL SAFETY DATA SHEET <br /> Guar Gum <br /> 25 March 2004 <br /> ' 't3:Acaitlental Release Mgasures <br /> ' Wear appropriate protective clothing and equipment. Caution: Guar gum is very slippery when wet. Sweep up or <br /> vacuum, avoiding the creation of airborne dust, and collect into a suitable container for disposal. Keep spilled <br /> product away from flammable and combustible materials. Wash residual traces with hot water after sweep-up is <br /> complete. Test area for residual slippery conditions. <br /> .Haihdhh t a6d ttbiib <br /> Handling: Avoid generating and breathing dust. Avoid eye contact. Use with adequate local exhaust ventilation <br /> and dust collection to maintain the concentration of airborne dust below the exposure limits. If clothing becomes <br /> contaminated, remove and launder before re-use. Wash thoroughly after handling. <br /> ' Storage: Keep product dry. Store in a cool, dry area. Keep containers closed to avoid moisture absorption. <br /> $.1 tcposure Con`tr`ols/Personal protection <br /> ' Engineering Controls: Use explosion proof local exhaust ventilation as needed to maintain exposure <br /> concentrations below the recommended limits. Consult a qualified engineer for evaluation of materials handling <br /> and explsion protection system(s). <br /> ' Personal Protective Equipment(PPE): <br /> • Eye Protection: Safety glasses or goggles recommended. <br /> ' • Skin Protection: Rubber, plastic or leather gloves recommended. <br /> • Respiratory Protection: If the concentrations exceed the Threshold Value Limit(TLV), a NIOSH <br /> approved dust respirator, supplied air respirator or self-contained breathing apparatus is recommended. <br /> Select appropriate respiratory protection for respirable particulates based on consideration of the airborne <br /> workplace concentrations and duration of exposure. Select and use respirators in accordance with 29 CFR <br /> 1910.134 http://www.access.izi)o.gov/nara/cfr/cft-retrieve.htmlgpaf4el ,ANSI Z88.2 http://www.ansi.or , the <br /> NIOSH Respirator Decision Logic and good industrial hygiene practice <br /> ' <br /> http://www.edc.gov/niosh/homepage.htmi. <br /> 9.Physical and Chemical Properties <br /> ' Boiling Point: Not Applicable Specific Gravity: Not applicable <br /> Melting Point: Decomposes %Volatile: Not applicable <br /> Vapor Pressure: Not Applicable Evaporation Rate(Butyl Acetate=l): Not Applicable <br /> ' Vapor Density (Air-1): Not Applicable pH: 5-8 <br /> % Solubility in Water: Complete Octanol/Water Partition Coefficient: Not Applicable <br /> Odor/Appearance: Creamy white powder with a bean-like odor. <br /> ' 10.
