Do you need a tile to fix/repair timed or tracked events?

EX: if the missile event is out, no one has missile tile, it is player C's turn, can player C take 10 to fix it?

Might be helpful to mention that you are asking a question about Red November.

While I know what game you are asking about, I couldn't tell you the correct answer.

I think that if that character is more than 10 minutes away from that missle he would be able to spend 10 mins working on trying to get rid of it.

Someone else might know better.

Yes, he can repair it. The items are there just to provide bonus to your repairs, in case the odds are against you. For example, if you don´t have enough time because of water or the event is just too soon to happen (remember: The colored time marker cannot move over the timed event tile, if you want to repair it. So the items which are giving you bonus are quite helpful in such sticky situations.) Exceptions are: grog (lets you enter room on fire), fire extinguisher (same case) and aqualung (lets you enter the ocean).

Hope it helped.
