Use fire-extinguishing media appropriate for surrounding materials. Unsuitable extinguishing None known. media Specific hazards arising from Explosion hazard: Avoid generating dust; fine dust dispersed in air in sufficient concentrations and the chemical in the presence of an ignition source is a potential dust explosion hazard. Special protective equipment Wear suitable protective equipment. and precautions for firefighters Fire fighting Use water spray to cool unopened containers. As with all fires, evacuate personnel to a safe area. equipment/instructions Firefighters should use self-contained breathing equipment and protective clothing. Specific methods Use standard firefighting procedures and consider the hazards of other involved materials. 6. Accidental release measures Personal precautions, Keep unnecessary personnel away. Dust deposits should not be allowed to accumulate on protective equipment and surfaces, as these may form an explosive mixture if they are released into the atmosphere in emergency procedures sufficient concentration. Wear appropriate personal protective equipment. Avoid inhalation of dust from the spilled material. Ensure adequate ventilation. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. For personal protection, see section 8 of the SDS. Methods and materials for Avoid the generation of dusts during clean-up. Sweep up or vacuum up spillage and collect in containment and cleaning up suitable container for disposal. Clean surface thoroughly to remove residual contamination. For waste disposal, see section 13 of the SDS. Environmental precautions Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling As a general rule, when handling USP materials, avoid all contact and inhalation of dust, mists, and/or vapors associated with the material. Clean equipment and work surfaces with suitable detergent or solvent after use. After removing gloves, wash hands and other exposed skin thoroughly. Avoid significant deposits of material, especially on horizontal surfaces, which may become airborne and form combustible dust clouds and may contribute to secondary explosions. Combustible dust clouds may be created where operations produce fine material (dust). Select and use containment devices and personal protective equipment based on a risk assessment of material potency and exposure potential. Conditions for safe storage, Store in tight container. This material should be handled and stored per label instructions to ensure including any incompatibilities product integrity. 8. Exposure controls/personal protection Occupational exposure limits No exposure limits noted for ingredient(s). Biological limit values No biological exposure limits noted for the ingredient(s). Material name: Gadobutrol USP SDS US 1287449 Version #: 05 Revision date: 04-27-2023 Issue date: 01-08-2020 2 / 6 PAGE 3 Appropriate engineering For laboratory operations, use local exhaust ventilation or a ventilated enclosure for high energy controls operations such as particle sizing. Control exposures to below the occupational exposure level (if available). Select and use containment devices and personal protective equipment based on a risk assessment of exposure potential. Cover all containers for solutions and slurries while being transferred. Individual protection measures, such as personal protective equipment Eye/face protection Wear safety glasses with side shields, chemical splash goggles, or full face shield, if necessary. Base the choice of protection on the job activity and potential for contact with eyes or face. An emergency eye wash station should be available. Skin protection Hand protection Wear nitrile or other impervious gloves if skin contact is possible. When the material is dissolved or suspended in an organic solvent, wear gloves that provide protection against the solvent. Other Train employees in proper gowning and degowning practices. Wear lab coat. Base the choice of skin protection on the job activity, potential for skin contact and solvents and reagents in use. Do not wear protective garments in common areas (e.g., cafeterias) or out-of-doors. Respiratory protection Respirators are generally not required for laboratory operations. Use a tight-fitting full-face respirator with HEPA filters for spill cleanup. Choose respiratory protection appropriate to the task and the level of existing engineering controls. Thermal hazards Wear appropriate thermal protective clothing, when necessary. General hygiene Handling practices in this SDS are recommendations for laboratory use of USP materials. considerations 9.
