I’m not sure what version you are in , if you are in 5.0 or below , there are no
Agent Events, For Item Master
Agent Type: ITEM
Events : you won't get any events - so the basic problem is you can't listin on any specific event for ITEM

About 5.5 I'm not sure , if you find any events for Item in 5.5 you can configure this
-- On Item create - manual or Integration
---in Agent Actions write a saved query: check the Haz flag :
If yes
Send Notification: User Id

else:
No action.
