SECTION VI TOXICOLOGY INFORMATION
ACUTE TOXICITY STUDIES: Acute toxicity studies have not been conducted on this product, but acute studies have been conducted on a similar product. The results are shown below.
ACUTE ORAL TOXICITY (ALBINO RATS): LD50 = Greater than 15,380 mg/kg
Some hypo activity was exhibited at 10,250 mg/kg and above within 5 minutes after dosage which subsided within 6-22 hours. No pharmacotoxic symptoms were noted. Necropsy did not reveal any gross pathologic alterations.

INCOMPATIBILITY: Avoid contact with aluminum.
Avoid contact with strong acids (e.g. sulfuric, phosphoric, nitric, hydrochloric, chromic, sulfonic) which can generate heat, splattering or boiling and the release of toxic fumes.
SECTION X PERSONAL PROTECTION EQUIPMENT
RESPIRATORY PROTECTION: |
Respiratory protection is not normally needed since the volatility and toxicity are low. If significant vapors, mists or aerosols are generated, wear a NIOSH approved or equivalent respirator. For large spills, entry into large tanks, vessels or enclosed small spaces with inadequate ventilation, a positive pressure, self-contained breathing apparatus is recommended. |
VENTILATION: |
General ventilation is recommended. |
PROTECTIVE EQUIPMENT: |
Use impermeable gloves and chemical splash goggles when attaching feeding equipment or doing maintenance. If clothing is contaminated, remove clothing and thoroughly wash the affected area. Launder contaminated clothing before reuse. |
HUMAN EXPOSURE CHARACTERIZATION: |
Based on PACE Technologies Consumables recommended product application and our recommended personal protective equipment, the potential human exposure is LOW |
SECTION XI SPILL AND DISPOSAL INFORMATION
SPILL CONTROL AND RECOVERY:
Small liquid spills:: |
Contain with absorbent material, such as clay, soil or any commercially available absorbent. Shovel reclaimed liquid and absorbent into recovery or salvage drums for disposal. Refer to CERCLA in Section XIV. |
Large liquid spills: |
Dike to prevent further movement and reclaim into recovery or salvage drums or tank truck for disposal. Refer to CERCLA in Section XIV. |
DISPOSAL: |
If this product becomes a waste, it does not meet the criteria of a hazardous waste as defined under the Resource Conservation and Recovery Act (RCRA) 40 CFR 261, since it does not have the characteristics of Subpart C, nor is it listed under Subpart D. As a non-hazardous liquid waste, it should be solidified with stabilizing agents (such as sand, fly ash, or cement) so that no free liquid remains before disposal to an industrial waste landfill. A non-hazardous liquid waste can also be deep-well injected in accordance with local, state and federal regulations. |
SECTION XII ENVIRONMENTAL INFORMATION
If released into the environment, see CERCLA in Section XIV.
ENVIRONMENTAL HAZARD AND EXPOSURE CHARACTERIZATION: Based on our Hazard Characterization, the potential environmental hazard is: LOW.
Based on PACE Technologies recommended product application and the product’s characteristics, the potential environmental exposure is: LOW.
