While highly useful industrially, carbon tetrafluoride has some negative environmental and health attributes that must be considered responsibly:
In its normal gaseous form, CF4 poses little acute toxicity hazard for humans. However, in confined spaces it acts as a simple asphyxiant by displacing breathable oxygen. Long-term exposure may affect the liver and heart at very high concentrations.
The major concerns with CF4 relate to its environmental persistence and greenhouse effects. It has an atmospheric lifetime of 50,000 years. CF4 has a global warming potential around 7,000 times higher than carbon dioxide on a molecule per molecule basis.
Once emitted, CF4 migrates to the stratosphere. The stable carbon-fluorine bonds make CF4 highly resistant to degradation reactions. This means CF4 essentially has an indefinite lifespan once released unless specifically scavenged and recycled.
Stringent protocols and capture methods are thus essential when handling CF4 to prevent any release into the environment and minimize leakage from industrial systems. The benefits of its special properties must be balanced with the real global warming risks.
