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 the potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal breathing and skin protective equipment.
