Procedure Handbook. Surface Preparation and Painting of Tanks and Closed Areas.

摘要

A desperate need exists in shipyards for the proper planning and execution of surface preparation and coating operations in tanks and other enclosed areas. Abrasive blasters and painters are exposed to high concentrations of dust and hazardous organic vapors. Other shipyard personnel are exposed to the potential dangers of explosion and fire. Another aspect of the need for better planning concerns the inefficient utilization of capital, manpower and material assets. As an example, many extra manhours of labor are consumed in tank surface preparation operations because the abrasive blaster, when operating in tanks, just cannot see what he is blasting due to dust accumulation. Also, many square feet of painted surface are lost due to solvent entrapment during cure resulting in catastrophic peramature paint failure.
