Environmental Impact
Tests with CF7 show it readily biodegrades at low temperatures and has a relatively low oxygen demand (BOD) when compared to glycol-based deicers. CF7 is recognized as "relatively harmless" by the US Fish and Wildlife scale. In addition, the fluid does not contain nitrogen. Therefore, CF7 is considered much safer for the environment than either glycol or urea.
As suggested by federal agencies, the following general summary of environmental and hazard information is provided. More detail is available in the MSDS. Complete test report documentation is available upon request.
Biodegradability
The chemical oxygen demand (COD) of CF7 was determined using Environmental Protection Agency (EPA) Method 410.1.
The biological oxygen demand (BOD) of CF7 was determined using the EPA approved dilution method (Hach).
- BOD5 @ 10°C = 0.15 gm O2/g
- BOD5 @ 20°C = 0.25 kg O2/kg
Aquatic Toxicity
Current EPA methods were used for measuring the acute and chronic toxicity of CF7.
- Fathead minnow 7-day chronic, LC50 (mg/L) ........ > 1500
- Rainbow trout 96-hour acute, LC50 (mg/L). .......... > 2100
- Daphnia magna 48-hour acute, LC50 (mg/L) ......... > 3000
Hazard Information
- Hazardous Waste & Shipping
The RCRA regulations define hazardous waste in two ways: a listed hazardous waste or a characteristic hazardous waste. CF7 is not a listed hazardous waste. A waste may be considered hazardous if it exhibits any one of four characteristics - Corrosivity, toxicity, ignitability, or reactivity. A waste is corrosive under RCRA if it has a pH less than or equal to 2.0 or greater than or equal to 12.5. CF7 is not RCRA corrosive, toxic, ignitable or reactive; therefore, it is not a characteristic hazardous waste.
- No Hazardous Components
CF7 contains no hazardous components as described by SARA Title III, Section 302. Nor is CF7 designated as a hazardous chemical by the U.S. Department of Transportation. CF7 does not contain nitrates.
- Spill Handling Procedures
CF7 is not expected to present environmental problems. If product should spill, it should be absorbed and the resulting waste disposed of in a sanitary landfill unless state or local regulations prohibit such disposal.
- Container and Product Disposal
Based on information available to Cryotech Deicing Technology, CF7 is neither listed as a hazardous waste, nor does it exhibit any of the characteristics that would cause it to be classified or disposed of as a RCRA hazardous waste. Empty containers and product unsuitable for normal deicing operations may be disposed of in a sanitary landfill unless state or local regulations prohibit such disposal.
