Shelf heights are 10cm, 50cm, 90cm
and 130cm above the ground.
|If shelf heights
between 10 and 150cm, use shelf that most closely matches.
If shelf heights are at 0cm or
between 150 and 175 cm reduce weight.
If shelf heights above 175cm
no lifting should occur from that height.
|If shelf heights
are lower than ground level = reassess
Reach distances are 30cm to first
box, 50cm to second box and 63cm to third box on shelf
|If reach distances
are increased reduce weight
||If reach distance
decreased - reassess
1 lift every 2 minutes for a duration
of 2 hours
|If frequency increased
If duration increased reduce
If duration is for more than 8
hours - reassess
|If frequency decreased
If duration decreased - reassess
|Size of person
Stature 169 cm
Shoulder height 140 cm
Elbow height 110 cm
Knuckle height 76 cm
Knee height 47 cm
Mid lower leg 36 cm
No twisting during lifting
|If any twisting
occurs reduce weight
Compact, evenly distributed load
lifted using two hands with good hand holds.
|If load is large,
unstable or difficult to handle reduce weight.
If there are poor hand holds
If load lifted by one hand only
- with two hands; and
- using a recognised lifting technique;
- from a specific position detailed
in the diagram; and
- with ample space to lift object;
- placed onto a table or belt and
knuckle height; and
- no precision placement is required
- with no more than two steps taken;
- on good floor surfaces; and
- in good environmental conditions.
|If item is placed
on the ground or at height reassess
If more than two steps are taken
If object lifted while kneeling
If lifting occurs in restricted
If lifting occurs on slippery floors
If precision placement of the object
is required - reassess
If lifting occurs in an unfavourable
environment (i.e. 1926oC, relative humidity 35-50%) - reassess
|If object slid
close to the body before lifting use weights for first box.
Lifting and lowering is conducted
at a slow speed.
|If lifting or lowering
occurs at a speed of 75cm per second or more - reassess
Object lifted from shelf and placed
without precision onto a belt or pallet or trolley at knuckle
height while close to the body.
|Object placed to
a position below knee height or above elbow height reduce
