You attack the man

You spin on your heel. You drive a punch into your would-be attacker's throat, then a knee into his balls. He doubles over with a strangled groan. Grabbing a broken wooden plank, you swing it across his head with a loud crack. He collapses sideways into a pile of crates, bleeding, and clutching his crotch in a pitiful daze. The sound of movement can be heard from within the warehouse, and before they have a chance to capitalize it, you're out of there.
