石綿

1. Origins, structure, and basic meaning

• Structure: 石綿 is read as いしわた and is a noun for asbestos, a fibrous mineral formerly used in building materials and other products.
• Basic usage: Use 建材に石綿が含まれる for checking its presence and 石綿を扱う作業 for work that handles it.

2. Common pitfalls and similar expressions

• Inspection and handling
  • Testing whether old materials contain it differs from work that directly handles it, for which the source calls for specialized measures.
• Not ordinary cotton
  • Although the spelling contains 綿, the word identifies asbestos, not textile cotton or common padding.
