TranSafeliner™ Bulk Instruction Manual
MA4045RAD1114-6
8.15.1. Using the carbon dioxide analyzer:
a. Upon arrival, the container with TSL
TM
can be checked using the CO
2
analyzer.
b. Using the analyzer, carbon dioxide
levels can be checked through the
plastic valve with a flexible adapter
hose before unloading. Increased
carbon dioxide level indicates the
absence of any source of leaks from
punctures, holes, or damages. The
CO
2
level of ambient air is 0.04%.
8.15.2. Monitoring of carbon dioxide levels is recommended to ensure control of insect infestation.
Details of using the CO
2
analyzer are discussed in the analyzer’s instruction manual.
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.

CARBON DIOXIDE (CO
2
) SAFETY
8.16.1.
Carbon dioxide does not support life. It can act as a simple asphyxiant by diluting the
concentration of oxygen in air below the levels necessary to support life. As it is heavier than
air it will tend to concentrate at lower levels.
8.16.2. Avoid breathing in CO
2
. Do not get in the eyes, on the skin, or on clothing. Wear leather safety
gloves and safety shoes when handling cylinders.
8.16.3. Protect cylinders from physical damage. Do not drag, roll, slide or drop. While moving the
cylinder, always keep the removable valve cover in place. Never attempt to lift a cylinder by
its cap; the cap is intended solely to protect the valve. When moving cylinders, even for short
distances, use a cart (trolley, hand truck, etc.) designed to transport cylinders.
8.16.4. Never insert an object (e.g., wrench, screwdriver, and pry bar) into cap openings; doing so
may damage the valve and cause a leak. Use an adjustable strap wrench to remove over-
tight or rusted caps. Slowly open the valve. If the valve is hard to open, discontinue use and
contact your supplier.
8.16.5. Close the container valve after each use; keep closed even when empty.
8.16.6. Never apply flame or localized heat directly to any part of the container. High temperatures
may damage the container and could cause the pressure relief device to fail.
8.17.
PROCEDURE FOR PURGING WITH CARBON DIOXIDE (CO
2
)
8.17.1.
Calculation:
a)
Total Volume – Volume Occupied by the Commodity.
b) For every 2.0 kg CO
2
, 1 cubic meter of gas is being released.
c) Formula: (1 minus bulk density) x Volume (in m
3
) x 2
