Safety instructions
The container is designed to minimize hazards and prevent injury to personnel and equipment during
use. Normal precautions should be observed when handling the container locks, doors and lids. None
of the material used in the construction constitutes a personnel health risk.
The dry ice used as a refrigerant is considered a Class 9 dangerous cargo with the UN identification
number 1845 and is described as “Carbon Dioxide, Solid”.
Do not allow any exposed skin or body part to make physical contact with dry ice. Given the extreme
cold temperature of dry ice (-78.5°C / -109°F), severe frostbite can occur within seconds. Personnel
handling dry ice must use gloves or other insulating material.
Dry ice sublimates into large amounts of CO2gas. This colorless, odorless gas is heavier than air and
can accumulate and displace oxygen in low areas. Do not enter areas where CO2may have
accumulated without ventilating the space.
The container
The RKN and RAP containers are temperature controlled air cargo containers used to transport
temperature sensitive cargo in the refrigerated, controlled room temperature and deep frozen product
temperature ranges. In general, the product temperature to be maintained must be less than the
ambient temperature.
The container consists of two primary parts; the cargo space and the dry ice bunker (refer to Figure
1 and Figure 2 on the following pages). A temperature sensor located in the cargo space monitors
the air temperature, and when cooling is required, a fan is activated. Air from the cargo space is drawn
around the dry ice bunker where it is cooled before re-entering the cargo space.
Dry ice is contained in a separate bunker, which prevents carbon dioxide gas from entering the cargo
space and allows personnel to add dry ice to the container without disturbing the cargo area.
The cooling system uses dry ice as a refrigerant and D-cell alkaline batteries to power the control unit
and fan(s). The RKN uses one fan for air distribution while the RAP uses two fans.
The RKN is a fork liftable LD-3 air cargo container designed to hold one pallet (EUR 1200 x 800 mm
/ US 48 x 40 in) of cargo. The RAP is an LD-9 air cargo container designed to hold four pallets
(EUR 1200 x 800 mm / US 48 x 40 in) of cargo. The RAP can be moved with a fork lift only when empty,
and must be moved with a roller bed system when it is loaded.
