Voyager requires polyferranide to seal the warp core and prevent the nacelles from burning themselves up.

It takes at least 20 minutes to augment the engines with power from the auxiliary fusion reactors and that only results in an 8 per cent boost in power.

Inertial dampeners go offline in the shuttle that is used to search for the polyferranide deposits.

Starfleet protocol requires that members of an away team remain armed and ready to defend themselves until contact is made. (Tuvok reminds Chakotay. In [#49 Sacred Ground] Tuvok reminds Janeway that it is standard procedure for away team members to be armed.)
