There are no risks of acute toxic effects for aquatic wildlife in streams receiving runoff from land where FireIce® is applied to fuels (vegetation) at any coverage level (application rate) during firefighting activities, or where planned aquatic releases in normal operating dilutions such as those of the residual FireIce® in the tank of amphibious aircraft during or after water scooping operations; or issues associated with the wash-down or clean-up of mixing facilities (airtanker bases) where mixing into storm water run-off infrastructure is planned to occur.
