1.

In the directions for use of the additive and premixture, the storage conditions and stability to heat treatment shall be indicated.

2.

For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from its use. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with protective equipment, including breathing, eye and skin protections.
