USAGE INSTRUCTIONS (continued)
BLOCKAGE PREVENTION
In the event of a chute blockage, the chute system could
tear away from the building causing serious injury or
death. To prevent blockages follow these guidelines:
• Ensure falling debris can be seen to exit the chute and
enter the container (see the sketches on the left).
• Make sure the chute is hanging straight (vertically).
Horizontal displacement of the chute must not exceed
20% of the height. Have the chute reinstalled if it does
not meet this criteria.
• Make sure the chute is not bent over balconies, shelves,
or similar structural protrusions. These obstructions
could crimp the chute and lead to a blockage. Have the
chute reinstalled if it is bent or crimped.
• Only introduce debris with dimensions that are less
than half the diameter of the chute. For example: if
using a 30” (76 cm) diameter chute, the maximum
allowable dimensions of the debris are 15” x 15” x 15”
(38 cm x 38 cm x 38 cm).
• Do not use motorized loaders to introduce debris into
the chute (motorized loaders introduce too much debris,
too quickly).
• Break-up debris before throwing it into the chute.
• Move the discharge end around the container to prevent
it from clogging as the container fills.
• Inspect the chute for blockages frequently.
• Designate a safety monitor who will, in addition to
monitor for blockages, supervise the safety of the entire
debris removal operation.
• Use load cells to monitor the chute weight and detect
blockages (see page 42 for more load cell information).
WRONG
Falling debris cannot be seen to exit the
discharge end of the chute. This situation
prevents blockages from being noticed.
RIGHT
Falling debris can be seen to exit the
discharge end of the chute and enter the
container.
WRONG
The container is overfilled. This could
cause the chute to fill from the bottom and
collapse. Do not overfill the container.
