Do not ever put your welding gloves in water! The water heats up near fire, turns to steam, and burns you. Do not put welding helmets down with the eye shield facing down. Do not set grinders down until they stop running. Keep wires away from anything that spins or sparks. Don't touch anything that has a chance of being hot. Keep a barrel of water nearby at all times for both dipping hot metal and emergencies. Keep a medical kit somewhere in the area. Maintain a clean and clear area, for a managed workspace is normally a safer workplace.
