SRP: Expired or waste pharmaceuticals shall carefully take into consideration applicable DEA, EPA, and FDA regulations. It is not appropriate to dispose by flushing the pharmaceutical down the toilet or discarding to trash. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator.
Product: Offer surplus and non-recyclable solutions to a licensed disposal company; Contaminated packaging: Dispose of as unused product. /Pravastatin sodium salt hydrate/
ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Avoid breathing vapors, mist or gas. Environmental precautions: Do not let product enter drains. /Pravastatin sodium salt hydrate/
Precautions for safe handling: Provide appropriate exhaust ventilation at places where dust is formed. /Pravastatin sodium salt hydrate/
Appropriate engineering controls: General industrial hygiene practice. /Pravastatin sodium salt hydrate/
Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. /Pravastatin sodium salt hydrate/
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.

12.1 Toxicity
Pravastatin's production and administration as a medication may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 6.0X10-16 mm Hg at 25 °C indicates pravastatin will exist solely in the particulate phase in the atmosphere. Particulate-phase pravastatin will be removed from the atmosphere by wet and dry deposition. Pravastatin contains chromophores that absorb at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, pravastatin is expected to have moderate mobility based upon an estimated Koc of 250. The estimated pKa of pravastatin is 4.2, indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.0X10-15 atm-cu m/mole. Biodegradation data in soil or water were not available. If released into water, pravastatin is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is expected to be a
