Ideally if it's a sterile product it'll never be in contact with the same atmosphere the worker is in, so clothes policy is mostly for the protection of the worker.
Not really. People shed skin and hair constantly, and the small particles float in the air and distribute themselves throughout the volume. And your bacteria are along for the ride. One of the functions of the protective suits, gloves and hairnets is to contain these these particles and thus keep the air as clean as possible. When combined with lamina airflow, positive room pressure and other techniques, it keeps contamination down hugely.

Hmm, well, best to avoid watching the "how it's made" about sutures then.
