The purpose of the research was to provide the database of Shipyards in southern Thailand and
to study a vivid opaque lead oxide (Pb
3
O
4
) for the use of boat repairing work, to get rid of waste
and lead stain in the factory, including workers aspect and workers health care behavior that might
concerned the way to receive and distribute lead. From the comprehensive survey of the boat
repairing factories, all boat repairing factories were registered at Industry Factory Department.
All features of work concerned wooden boat repairing (boat size more than 14 meters or contain

) for repairing and building and 84% was
the dust of vivid opaque lead oxide (Pb
3
O
4
). 2% of workers used sometime chemical masks and gloves
that unappreciated equipment . 38% of shipyard used the vivid opaque lead oxide (Pb
3
O
4
) about
5-6 kilograms per a boat. Thus, using total of the lead from southern Thailand were 25,762 kilograms
per a year. Interview 595 workers, 75.8% male, 82% caulker and 95% of workers was employed daily,
