CONTROLLED ATMOSPHERE (CA) SAFE CONTAINER ENTRY

Entry into a CA equipped container must be performed by a (minimum) two person team. The operator will be the person
performing the required procedures and that person is to be supervised by someone who is familiar with the required
procedures. The person supervising entry must ensure that all venting procedures outlined in section 10.7 page 113 have
been performed and all waiting periods have expired. The following steps must be adhered to:
1. Both persons are to read and understand the preceding Safety Considerations and all hazard labels on the unit.
2. The supervising person is responsible for keeping all persons away from open doors and access panels until the
venting procedure is completed.
3. Avoid opening doors of a low-oxygen level container while at a loading platform. Never open doors if rain or refrig-
eration barriers are near the door. Low-oxygen content gas will exit the container and can asphyxiate nearby per-
sonnel who are working an adjacent container or are in the warehouse. Instead, follow the venting procedure before
backing up to the loading platform.
4. Avoid venting in a confined space.
5. A hazardous low-oxygen atmosphere exists within the evaporator section. Before opening the evaporator access
panel(s) the container must first be ventilated per section 10.5, page 114. Then the access panel(s) must be open
for 10 minutes before working inside the evaporator section.
6. The supervising person will declare it safe to enter the container. Prior to entry the supervisor or a second person
must be present. Every time the doors or panels are to be opened, the supervising person must ensure the venting
procedures are performed and the waiting times have expired prior to declaring the container safe to enter and
allowing any person to enter. Every time.

ALWAYS:

Look for Danger, Warning and Caution hazard labels on containers. Use a flashlight if necessary!
S
Assume there is a low-oxygen atmosphere present when the doors are closed.
S
Assume low-oxygen content even if there was air yesterday.
S
Assume low-oxygen content even if the CA start-stop switch (CAS) is OFF.
S
Assume low-oxygen content even if no generator set is attached.
S
Assume low-oxygen content even if the container has no load in it.
S
Assume low-oxygen content even if the door is not locked.
S
Assume low-oxygen content even if the container is in for maintenance.
S
Assume low-oxygen content even if the container is to be washed out.
S
Use your watch and write times down when ventilating a container.
S
Warn others of the hazard. Tell them from a distance if necessary.
S
Ask qualified personnel if you are not sure or forgot some of this training.

RESUSCITATION

Personnel working with or near hazardous atmosphere or materials shall be familiar with approved resuscitation
methods. If someone is injured and stops breathing, initiate resuscitation immediately. A delay could cost the victim's
life.

RESCUE

-- All rescue personnel shall have adequate supplies of oxygen or air from self-contained breathing apparatuses or
fresh air lines
-- Only those who are properly trained in the use of self-contained breathing apparatus will attempt to rescue the
victim. All other personnel will stay clear of the area until the oxygen level stabilizes.
-- The victim shall be removed to the open air without delay and shall be kept warm. Oxygen shall be administered or
artificial respiration shall be applied by an approved method.
-- Resuscitation procedures shall be continued until the patient revives or until a doctor gives instructions.

FIRST AID

-- Persons suffering from lack of oxygen should be quickly moved to areas with normal atmosphere.
-- If the person is not breathing, assisted ventilation should be the first step.
-- Give supplemental oxygen with ventilation if oxygen is available.
