ENTERING CONTAINER IN AN EMERGENCY
In case of a power failure to the unit, there is no emergency provision to unlock the automatic door interlock system:
DANGER
WHEN OVERRIDING THE CA CONTROLLER, THE OPERATOR MUST BE AWARE OF THE IMMEDIATE
DANGER OF UNCONSCIOUSNESS AND DEATH. THE OPERATOR MUST READ AND UNDERSTAND ALL
WARNING LABELS AND SAFETY INSTRUCTIONS BEFORE PROCEEDING WITH THE EMERGENCY BY-
PASS PROCEDURE.
To enter the container in a true emergency situation, do the following:
1. Ensure at least two persons are present. One person is to act in a supervisory manner, and that person is charged
with the responsibility to ensure all procedures are performed correctly and all waiting times have expired before
allowing entry.
2. Open the fresh air makeup vent 100% (fully open). Avoid any direct breathing of venting gases from the air makeup
vent.
3. To enter the container, the interlock system must be removed. To remove the system, remove the center bolt from
the catch or remove the four screws holding the interlock system to the container door. Refer to Figure A.
WARNING
Low oxygen levels inside container. Ventilate container before entering. Stay away from doors while
venting.
4. Fully open container doors.
5. Pull back the curtain (poly sheet) to accelerate the time of a complete ambient air exchange.
6. Step away from the container rear doors. Do not close doors. Wait 30 minutes prior to entry or unloading of the
container. Wait 45 minutes before climbing on contents inside of the container.
7. If access to the container is necessary (i.e., life and death situations) prior to the safety venting procedures being
performed, then: only rescue personnel trained in safety procedures in removing victims from hazardous atmo-
spheres are to be allowed entry into the container at this point.
8. All other personnel are to stay well clear of the doors.
