E. H. Jeffords to Sumner Simpson Enclosing Arkwright's Ruling That the Dust Tunnel Needs No Sprinklers (1935)

A letter of August 15, 1935, from E. H. Jeffords of Raybestos-Manhattan's General Asbestos & Rubber Division at North Charleston, South Carolina, to Sumner Simpson, president of Raybestos-Manhattan, with a copy of the letter it enclosed. In that letter of August 13, Edward A. Barrier of the Arkwright Mutual Fire Insurance Company wrote that because of the "very low percentage of cotton" in the dust samples, neither sprinklers nor a tinned floor were needed in the dust tunnel, so long as the dust stayed like the samples; at the 10% cotton first used in the mix, protection would be required. Jeffords told Simpson this would lower the tunnel's cost, that the dust house should be finished that week, and that he felt "satisfied that we are going to obtain good results" from the burlap bags in Building No. 3.

What it shows

This closes the summer's exchange with the fire insurer over the North Charleston dust collection system. Jeffords also enclosed his reply to Barrier (Jeffords to Barrier, August 15), and he said that whether to build the tunnel would be discussed with Simpson later, as a question of cost against renewing the old piping.

Proposes a meeting to discuss construction of tunnel.

02508. States that in view of the low cotton content of the dust samples, it has been determined unnecessary to install sprinklers in the tunnel or to tin the floor. If, however, cotton content could ever be higher these precautions would be needed. Requests blueprint of tunnel construction.
