The frequencies shown are suggested frequencies that may be modified by local
command, as individual installation conditions warrant.
(3)
Caution: Handle acids very carefully. Particularly, do not pour water into sulfuric
or chromic acid, as it will boil violently and splatter the acid over you. Such acid
will cause severe burns to the skin and clothes. Perform acid treatment only on
the approval of the plant superintendent and under the supervision of a chemist
or other qualified personnel.
(4)
Note: Chlorine gas introduced into the air line at intervals between inspections
helps hold down organic growths. Removable plates should be soaked in
50 percent nitric acid. Plates grouted in place cannot be treated with nitric acid;
use chromic acid (made by adding 1 g of sodium dichromate to 50 mL of sulfuric
acid). Pour approximately 2 fluid ounces on each plate on 2 succeeding days.
(5)
As the component materials cannot be subjected to strong acid or heat, scrub the
diffusers with a brush and detergent.
(6)
Do not use a pipe wrench for this purpose.
