Depending on exactly where you will be expected to travel, you might want to ask about security escort arrangements. E.g. a friend of mine often travels to places your average tourist would not in parts of Africa, and an armed security detail, and a secure (not sure if it is bullet proof, but could well be) vehicle with a driver trained to avoid ambush etc. is a standard part of his 'must haves' in his package. His company also has a contract with a private company that is on standby should they need hostage negotiations. Personally, I think he is bonkers, but he also knows how to take care of himsefl (ex-army), so figure he has a good grasp on what is reasonable for an employer to provide in those areas.

My father has a standard clause in his contract that specifies he will not travel on certain airlines within Africa (I can't recall the term, but it is basically the notoriously unsafe airlines that aren't allowed in international airspace) and as such if he has to fly A to (Middle East for example) to B, rather than directly A-B, the client will pay for it.
