| 103. | Rubber fume is fume evolved in the mixing, milling and blending of natural rubber or synthetic elastomers, or of natural rubber and synthetic polymers combined with chemicals, and in the processes which convert the resultant blends into finished products or parts thereof, and including any inspection procedures where fume continues to be evolved. |
| 104. | Rubber process dust is evolved during the manufacture of intermediates or articles from natural rubber and/or synthetic elastomers. This definition does not include dusts, which, for occupational purposes, can be dealt with individually. In each case the relevant OEL will apply. |
| 105. | Dust produced by the abrasion of cured rubber should be dealt with as particles (insoluble or poorly soluble) not otherwise specified [PNOS], i.e. dust of any kind when present at a substantial concentration in air. |
