DRY ICE TRANSPORTATION
This section presents the general conditions for dry ice (carbon solid
dioxide) transportation in the EMB-145, ERJ-140 and EMB-135 cargo
compartment.
The main reference that regulates and state methods and procedures
to handling, appropriate packaging, legal aspects for dry ice
transportation, etc. is the IATA Dangerous Goods Regulations.
GENERAL RECOMMENDATIONS
It is not recommended to transport dry ice in the cabin and in the
galleys. If small quantities are present in the galley, it is required to
compute this dry ice mass in the calculation of the total dry ice.
Prior to enter into the cargo compartment in which a large amount of
dry ice has been loaded, ensure that adequate ventilation is provided
checking that the cargo ventilation system is running properly. If this
condition is not met, avoid storing dry ice on airplanes for extended
periods of time.
Similar precautions must be followed when entering any area,
adjacent to a cargo compartment, loaded with dry ice. If adequate
ventilation is not provided, it is recommended to wear oxygen mask
and portable oxygen cylinder inside these areas. In addition, animals
should not be transported on a cargo compartment loaded with dry ice.
Both air conditioning packs (or equivalent ground cart ventilation) shall
be operating while persons are on board of an airplane transporting
dry ice.
In case of failure of the cargo ventilation system during flight, the CO
2
sublimated in the cargo compartment may spread in the airplane, but
the fresh air flow that comes from the packs dilutes the CO
2
concentration below 0.5% CO
2 in volume. The airplane can continue
the flight normally, but after landing it is required to follow special
procedures to ventilate the place in which CO
2 buildup is suspected.
