Remove contaminated clothing. For treatment advice, seek guidance from an occupational health physician or other licensed health-care provider f amiliar with workplace chemical exposures. In the United States, the national poison control number is 1-800-222-1222. If person is not breathing, give artif icial respiration. If breathing is dif f icult, give oxygen if available. Persons developing serious hypersensitivity (anaphylactic) reactions must receive immediate medical attention. If Inhaled If breathing is dif f icult, remove to fresh air and keep at rest in a position comf ortable f or breathing. Call a physician if symptoms develop or persist. In Case of Skin Contact Wash of f with soap and water. Get medical attention if irritation develops and persists. In Case of Eye Contact Flush eyes with water as a precaution. Get medical attention if irritation develops and persists. If Swallowed Rinse mouth. If ingestion of a large amount does occur, call a poison control center immediately. Most Important Symptoms and Effects Provide general supportive measures and treat symptomatically. Section 5: Fire Fighting Measures Suitable Extinguishing Media Water spray, dry chemical, carbon dioxide, or f oam as appropriate f or surrounding f ire and materials. Special Hazards Arising From the Substance/Mixture Explosion Hazard: Avoid generating dust; f ine dust dispersed in air in suf f icient concentrations and in the presence of an ignition source is a potential dust explosion hazard. Special PPE and/or Precautions for Firefighters Wear suitable protective equipment. As with all f ires, evacuate personnel to saf e areas. Firef ighters should use selfcontained breathing equipment and protective clothing. Cool containers exposed to f lames with water until well af ter the f ire is out. Page 1 of 4 Section 6: Accidental Release Measures Personal Precautions, Protective Equipment and Emergency Procedures Dust deposits should not be allowed to accumulate on surf aces, as these may f orm an explosive mixture if they are released into the atmosphere in suf f icient concentration. Keep unnecessary personnel away. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Ensure adequate ventilation. Wear appropriate personal protective equipment. Methods and Materials Used for Containment Sweep up or vacuum up spillage and collect in suitable container f or disposal. Avoid the generation of dusts during clean-up. For waste disposal, see section 13 of the SDS. Wash spill site. Cleanup Procedures Sweep up or vacuum up spillage and collect in suitable container f or disposal. Avoid the generation of dusts during clean-up. For waste disposal, see section 13 of SDS. Wash spill site. Section 7: Handling and Storage Precautions for Safe Handling Combustible dust clouds may be created where operations produce f ine material (dust). Avoid signif icant deposit of material, especially on horizontal surf aces, which may become airborne and f orm combustible dust clouds and may contribute to secondary explosions. As a general rule, when handling USP Ref erence Standards, avoid all contact and inhalation of dust, mists, and/or vapors associated with the material. Clean equipment and work surf aces with suitable detergent or solvent af ter use. Af ter removing gloves, wash hands and other exposed skin thoroughly. Use of a designated area is recommended f or handling of potent materials. Conditions for Safe Storage Store in tight container as def ined in the USP-NF. This material should be handled and stored per label instructions to ensure product integrity. Section 8: Exposure Controls/Personal Protection Components with Workplace Control Parameters Material Magnesium Stearate (CAS 557-04-0) Type TWA Value 10 mg/m3 Appropriate Engineering Controls Airborne exposure should be controlled primarily by engineering controls such as general dilution ventilation, local exhaust ventilation, or process enclosure. Local exhaust ventilation is generally pref erred to general exhaust because it can control the contaminant at its source, preventing dispersion into the work area. An industrial hygiene survey involving air monitoring may be used to determine the ef f ectiveness of engineering controls. Ef f ectiveness of engineering controls intended f or use with high potent materials should be assessed by use of nontoxic surrogate materials. Handle in accordance with good industrial hygiene and saf ety practice. PPE - Eye/Face Protection Saf ety glasses with sideshields are recommended. Face shields or goggles may be required if splash potential exists or if corrosive materials are present. Approved eye protection (e.g. bearing the ANSI Z87 or CSA stamp) is pref erred. Maintain eyewash f acilities in the work area. PPE - Skin Protection Chemically compatible gloves. For handling solutions, ensure that the glove material is protective against the solvent being used. Use handling practices that minimize direct hand contact. Employees who are sensitive to natural rubber (latex) should use nitrile or other synthetic nonlatex gloves. Use of powder latex gloves should be avoided due to the risk of latex allergy. PPE - Body Protection Chemically compatible gloves. For handling solutions, ensure that the glove material is protective against the solvent being used. Use handling practices that minimize direct hand contact. Employees who are sensitive to natural rubber (latex) should use nitrile or other synthetic nonlatex gloves. Use of powdered latex gloves should be avoided due to the risk of latex allergy. For handling of laboratory scale quantities, a cloth lab coat is recommended. Where signif icant quantities are handled, work clothing may be necessary to prevent take-home contamination. PPE - Respiratory Protection Where respirators are deemed necessary to reduce or control occupational exposures, use NIOSH approved respiratory protection and have an ef f ective respirator program in place.
