  • (12) The work melting, casting, pulverizing, mixing or sieving lead, etc., or coating lead or peeling coated-lead in the processes of manufacturing products of rubber or synthetic resin, lead-containing paint, or colors, glaze, agricultural chemicals, glass, adhesives, etc. containing lead compounds
  • (13) The work soldering in the places where natural ventilation is insufficient (excluding the work carry out temporally, the same shall apply in the next item to item (16))
  • (14) The work glazing with a glaze containing lead compounds or baking objects glazed with the said glaze
  • (15) The work picturing with colors containing lead compounds on objects, or to baking objects pictured with the said colors, (excluding the work prescribed by the Ordinance of the Ministry of Health, Labour and Welfare among those works picturing with brushes or stamps, or those works baking objects using firing furnace equipped with local exhaust ventilation systems or exhaust pipes, those )
  • (16) The work hardening or annealing metals using molten lead, or sand-bathing the said metals
  • (17) The work picking type, typesetting or taking type into pieces in the power-using printing process
  • (18) The work cleaning at the workshops carrying out the work listed in the preceding each item (excluding the work listed in item (9))
Remarks
  • (1) "Lead, etc." means lead, lead alloys and lead compounds, and mixtures of these substances and others (excluding sintered ore, flue cinders, electrolytic slime and slag).
  • (2) "Sintered ore, etc." means sintered ore, flue cinders, electrolytic slime, slag which are produced in the smelting or refining processes of lead, and flue cinders and electrolytic slime which are produced in the smelting or refining processes of copper or zinc
  • (3) "Lead alloys" means alloys made of lead and other metalscontaining lead of 10% or more of the said alloy by weight.
  • (4) "Lead-containing paint" means the paint containing lead compounds
