ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer It is strongly advised not to let the chemical enter into the environment because it persists in the environment. Avoid release to the environment in circumstances different to normal use.

N O T E S

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
