Notes

  • Lifting/lowering is required forthis job/task?
    • If checked, do weights exceedlevels in tables1 or 2?
  • Pushing/pulling is required for this job/task?
    • If checked, do initial push forces exceedlevels in tables 3 or 4?

Lift/Lower 

If lifting/lowering is required for this job/task, does weight of the object exceed value in the appropriate table?

Step 1: Choose the right table to use: If the task is performed by males only, use table 1.

If the task is done by females only, or both males and females, use table 2.

Step 2: Determine whether the lift/lower is close or far

Close – hands are 17 cm or less from body at all times during the lift/lower

Far – hands are more than 17 cm from the body at any time during the lift/lower

Step 3: Determine if the lift/lower is short or long

Short – the object moves up/down no more than 25 cm Long – the object moves up/down more than 25 cm

Step 4: Determine where the worker’s hands end up at the end of the lift/lower. 

Below knuckle height, between knuckle and shoulder height, or above shoulder height

Step 5: Determine how often the object is lifted/lowered – once every 15 sec., 1 min., 2 min., 5 min., 30 min., or 8 hours

Step 6: Compare the weight from the table to the actual weight of the object being lifted/lowered

Example: Only males do the job being assessed. The hands are more than 17 cm from the body, the item is moved up more than 25 cm, the worker’s hands at the end of the lift are at just below shoulder height and the item is lifted once every 5 min. The value from table 1 for this example is 19 kg. To get this number:

  1. Look at numbers in table 1
  2. Look at the numbers in the far-long row
  3. Find the numbers in the far-long row, under the heading “Hands end between knuckle and shoulder height” and
  4. Find the number for objects lifted once every 5 min. – 19 kg

Table 1. Lift/lower weights (kg) – use when task performed by males only

Push/Pull

If pushing/pulling is required for this job/task, does initial push force to move the object exceed value in the appropriate table?

Step 1: Choose the right table to use: If the task performed by males only, use table 3.

If the task is done by females only, or both males and females, use table 4.

Step 2: Determine where the worker’s hands are on the object while it is being pushed/pulled – at or below knuckle height, between knuckle and chest height, at chest height or higher

Step 3: Determine how far the object is pushed/pulled – up to 2 meters, 2 - 7.5 meters, more than

7.5 meters

Step 4: Determine how often the object is pushed/pulled – once every 15/20/30 sec., 1 min., 2 min., 5 min., 30 min., or 8 hours

Step 5: Compare the force level from the table to the actual amount of force required for the push/pull to the object

Example: Both females and males do the job being assessed. The hands are below the worker’s knuckle height on the object when it is being pulled, the item is pulled 1.5 metres, once a minute. The value from table 4 for this example is 17 kg. To get this number:

  1. Look at numbers in table 4
  2. Look at the numbers in the “At or below knuckle height” row
  3. Find the numbers in the “At or below knuckle height” row that are under the heading for “Up to 2 metres”
  4. Find the number for an object that is pulled up to 2 metres, once per min. - 17 kg

Table 3. Initial push/pull forces (kg) – use when task performed by males only (e.g. carts, trolleys, rolls, cables, wheelbarrows)
