Nacconal 35SL. It is a common industrial surfactant. Of the
many types of surfactants on the market, Calsoft was chosen
because it was:
(1)
Readily available in large quantities
(2)
Nonflammable
(3)
Disposable in effluent
(4)
Biodegradable
(5)
Acceptable for human health and safety
(6)
Adequate in foaming action
(7)
Stable at high temperature
(8)
Minimally corrosive
(9)
Cost effective for training
(10) Compatible with the flame control logic
b) Another substitute should not be attempted without
thoroughly considering each of these characteristics.
c) Calsoft can be delivered in a wide variety of
forms. The solid form comes in bags and drums. The liquid form
comes in cans, drums, and by tank truck in varying
concentrations. The liquid form is preferred for fire training.
d) Liquid Calsoft is sold in different concentrations
because higher concentrations contain less water therefore less
bulk for efficient shipping. However, 60 percent and higher
concentrations of liquid Calsoft should increase handling
problems for the user. In 60 percent concentrated form, Calsoft
should be heated to be transferred. If 60 percent Calsoft ever
cools below 10 degrees C, it should be heated and mechanically
mixed before it can be used. Calsoft should be bought as a 40
percent concentrate which does not have to be kept heated except
