- This is an urban legend. Halogen interferes with the burning chemistry in
- a complex way, but does not "displace" oxygen, unless of course you use so
- much you replace all the air in the area, but this is true with any gas.
- You are supposed to leave the area where halon is used on fires but because
- some halon-fire byproducts are toxic, not because there's no oxygen.
