Hi All I have just completed creation of a compressed air training course for our employees. Basic but covers enough to ensure they actually understand that if you mess with it, it will hurt. Anyway a question has arose out of the training Are there any specific first aid requirements for someone who may have been internally exposed to compressed air? I know the obvious: Try to keep calm Recovery position if unconscious ABC etc etc But is there any specific treatment a first aider can do to help someone who has been internally exposed to compressed air? I have searched but not come up with an definite answers Any help would be brilliant
