Schanze took a deep breath, produced a test-tube from inside of his jacket and began tapping it's side with his finger. "15 minutes exposure is fatal and I may have placed some dispensers upwind from the heliport, under the heliport and in the vending machines around the heliport that may go off in..." He paused as he glanced at his watch, "say, 20 minutes, it's colorless and odorless so they won't know about it, hence I'm telling you to tell them. I'm here to watch" reaching inside his jacket again, this time to the opposite breast pocket he pulled out a pair out expensive binoculars, a small notepad, a stopwatch and a pen. "If the team dies that's on you, I warned you fair and square and even was nice enough to give you time to complete your little mission if you hurry. I'd rather not use them as my guinea pigs, the heliport personnel will do fine for that."
