By “activating” OXINE (AH) you release more of the available chlorine in the solution.
When doing this it is recommended that you wear a NIOSH approved respirator.
Oxine used without being “activated” does not require the use of a respirator.
In its inactivated state (no activator pack) it is perfectly safe around humans and poultry.
But once activated you would not be able to fog the solution into any area where the birds are present.
Please note that OXINE AH does not have to be activated to be effective.
