if you use the search function:

based on what's in the thread, no, you can't activate IRS during the dmg step

You don't even need that topic. It's a basic game mechanic that only Counter Traps, Quick-Plays and Traps that directly modify ATK or DEF, and cards that specifically state they can be used during the Damage Step are the only effects that can be used anytime during the Damage Step. Either that, or it has to be ruled it can by UDE, which can be found on their website or Netrep.
