| |
0 - 100 | Comb. Fibre Storage Bin | |

501-1000 | Unprotected | Comb. Fibre Storage Vaule |
1000 - up | Protected | Comb. Fibre Storage Vault |
Up to twenty-five hundred (2500) cubic feet of loose fibres may be stored in a detached "loose house" suitable located, with opening properly protected against entrance of sparks. The loose house shall be used for no other purpose.
