7.9.2. The tension straps are long enough to raise and
apply tension to the sides of the Cocoon
TM
Lite,
even if it is only three-quarters full. The required
tension can be achieved by attaching the cords to
the buckles of the Cocoon
TM
Lite.

MONITORING THE OXYGEN LEVEL AND RELATIVE HUMIDITY (RH%)
7.10.1. Use of an oxygen analyzer:
a. During the first 15 days of installation,
oxygen level should be checked daily using
oxygen analyzer.
b. Succeeding monitoring should be done
twice a week. Normally, oxygen levels
should drop 1-2% per day to a level less
than 3% (though lower levels have been
observed as well). Oxygen levels go up by
few percent but must not exceed 7%. Except
for coffee beans and seeds, in this situation,
sealing is probably compromised, and the
commodity may not be adequately protected.
c. When the oxygen does not drop for 3 to 7
days or increase in carbon dioxide is not
observed, check for pinholes or damage in
the Cocoon sections.
Note:
▪
Carbon dioxide flushing must be also recommended for commodities that are fumigated or
processed (i.e., milled rice, yellow split peas).
▪
When planning to store for 2 months or less, carbon dioxide flushing is recommended to
ensure control of insect infestation.
7.10.2. Use of humidity indicator:
a. The humidity indicator is a special circular paper with moisture-sensitive chemical.
Its color changes from blue to pink when relative humidity exceeds 65%, and vice
versa.
b. The humidity indicator provides an affordable and quick reference to relative
humidity inside the Cocoon
TM
Lite.
c. It is easy to use and does not require meticulous preparation for installation.
d. The material is non-toxic, and disposal does not need any special treatment.
e. Procedures on how to use the humidity indicator:
