• No other work, for example, maintenance or repair work such as sand blasting or welding shall be performed at places where dock work is in progress if it is likely to endanger or obstruct the person carrying out dock work.
• When more than one gang of dock workers are employed in dock work simultaneously in a hold, it shall be ensured that
  
  • the operation of loading or unloading is harmonised to avoid dangers to the working gangs from one another;
  • the slung cargo of one gang will not endanger the dock workers of the other gang;
  • where gangs are working at different levels, a net shall be rigged and securely fastened to prevent dock workers from falling down or cargo falling on to dock workers below;
  • over crowding of gangs in a section of the hold is avoided.
