We have been recently introduced to this species, and so far things are going ok.
The human I'd expect to at least be familiar with escape routes and life saving equipment, while the alien I'll assume has at best a basic understanding of them. For the sake of relations between our people, and the likelihood that the alien is more screwed than the human by a lack of knowledge... ..I'd go with the alien first.
I'd probably make an abortive attempt at saving the human, but I'd not put myself in a situation I know I can't get out of.
