If the suits were permeable enough to let Hydrazine in they'd leak O2 like a kitchen sieve. Additionally, how exactly would the hydrazine diffuse into a positive pressure suit??? As long as He's got the suit on I don't imagine astronaut being in any danger, however, If he gets coated with hydrazine, He might have problems taking it off back in the shuttle.
