Description:

Essential Job Demands:

The Outgate Labourer is responsible for check-in procedures for incoming traffic at the outgate. There

are three lanes at the outgate (e.g., lane 1 for full and sealed containers and lane 2 and 3 for empty

containers). Sealed containers are not inspected. Empty containers are opened and visually inspected

for holes or damages. If a container is damaged, a short note is written on the container with chalk and

the checker is contacted via radio transmission. The truck driver is then asked to drive to the “trouble

gate” for further inspection. For undamaged empty containers, the Outgate Labourer removes placards

from the exterior using a scraper and/or mobile stairs as required. The Outgate Labourer is restricted

from climbing on the truck during inspection or placard removal. The top of the containers are

inspected at an overpass accessed by a stairway. As required, a long handle broom or shovel is used to

clean the top of containers. Each inspection takes approximately 6 minutes. In times of snow, the

worker would maintain clear access to the outgate lanes through shoveling or use of ice salt. When

there is infrequent incoming traffic, the Outgate Labourer has access to a sheltered sitting station.

Physical and Postural Demands:

Description:

• Lifting up to 4 kgbetween floor and shoulder level on a frequent basis.

• Lifting to above shoulder level is occasionally encountered.

• Lifting is interspersed with carrying.

• Repetitive lifting is rarely encountered when shovelling ice salt and weight of such load is

controlled by the worker.

• Unilateral carrying on a frequent basis.

• Carrying concurrently with stair climbing is encountered.

• Carrying while ambulating on even terrains with occasional slippery section is encountered.

Considerations for return to work programming:

• Worker needs to demonstrate the ability to ascend and descend stairs prior to return to the full

scope of this work position.

• Initial return to work attempts as an extra worker to allow for extra breaks and to work at the

worker’s pace concurrently with a graduated return to work should be considered.
