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. /Pioglitazone hydrochloride/

Precautions for safe handling: Further processing of solid materials may result in the formation of combustible dusts. The potential for combustible dust formation should be taken into consideration before additional processing occurs. Provide appropriate exhaust ventilation at places where dust is formed. /Pioglitazone hydrochloride/
Appropriate engineering controls: General industrial hygiene practice. /Pioglitazone hydrochloride/
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. /Pioglitazone hydrochloride/
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.

Data source: Hazardous Substances Data Bank (HSDB) via PubChem.

12.1 Toxicity
Pioglitazone'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 2.9X10-14 mm Hg at 25 °C indicates pioglitazone will exist solely in the particulate phase in the atmosphere. Particulate-phase pioglitazone will be removed from the atmosphere by wet and dry deposition. Pioglitazone contains pyridine- and anisole-like functional groups that do not absorb UV light at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, pioglitazone is expected to be immobile based upon an estimated Koc of 9000. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.7X10-12 atm-cu m/mole. Pioglitazone is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data ln soil or water where not available. If released into water, pioglitazone is 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 190 suggests the potential for bioconcentration in aquatic organisms is high. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environ

12.2 Persistence and degradability
No data available.

12.3 Bioaccumulative potential
Log P (n-octanol/water): 3.8
Potential for bioaccumulation exists (Log P > 3).
