A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. If a specific volume or frequency is not stated below, then evidence must be provided that the following requirements have been performed on at least one occasion:
stack timber and maintain timber stacks in line with safe work procedure, site standards and organisational requirements
follow organisational policies and procedures relevant to building and maintaining a timber stack
use safety gear and equipment required to build and maintain a timber stack, in line with site requirements
communicate and work safely with others in the workplace
identify and control hazards and risks associated with building a timber stack, in line with workplace requirements
safely build timber stacks appropriate to the needs of the workplace
record and report required timber stack and fault information in line with site requirements
safely repair faults in a timber stack.
A person competent in this unit must be able to demonstrate knowledge of:
work health and safety requirements, site standards and organisational policies and procedures for building and maintaining timber stacks
procedures for conducting a risk assessment which includes:
level and stability of individual packs
type of bearers
width, length and height of stack
weight of packs and stacks
duration of storage
type and strength of timber
type of lifting equipment
ground condition and stability in terms of slope, evenness, contamination and drainage
air-drying structure
unexpected obstacles
slippery or uneven surfaces
pedestrians on or near the timber stack
visibility
powered mobile machinery equipment faults or damage
ground strength to withstand the load of stacks and machinery
location of walkways, pathways and stores
top surface of ground
location of stack:
inside
outside under cover
in the open
monitoring and inspection procedures
storage area organisation
injury due to lifting, bending or crushing
machinery and equipment requirements
weather conditions.
procedures for identifying hazards and risks associated with building and maintaining timber stacks as outlined in the range statement
the use and importance of bearers including these needs:
be straight and not have knots
be identical in length in cross-section
not protrude from the stack
not be shorter than the stack
be laid flat
be in good condition
be able to withstand the environment
be checked for consistent thickness and shape
be correctly positioned
criteria for site surface stability and building a stack
factors contributing to avoidable loss including:
inadequate stack support
packs that are not level
exposing the stack to adverse drying conditions
inadequate stack conditions (poor drainage, stacks close to ground)
inappropriate site layout
inadequate stack protection
pack damage
unstable stacking
timber stacked too high
key components of a traffic management plan including:
ensure pedestrians are separated from powered mobile plants
allow safe entry and exit of mobile equipment and pedestrians
identify the most efficient route of travel
facilitate traffic flows
reduce the frequency of interaction with powered mobile plant
substitute a forklift with other suitable load shifting equipment
methods to visually estimate length of bearers and ratio, grading, colour identification and tagging of stacked timber
lengths, dimensions, tolerances, profiles and names of industry standard cross-sections
communication strategies including hand signals and gestures
common timber stack repair aspects including:
cordon off area from pedestrian access
install danger warning signage
replace damaged racking sticks, bearers or restraints
stabilise ground conditions, including top surface
stabilise packs and stacks
partially or fully rebuild packs and stacks
assess need for additional restraints
tighten loose restraints
timber stacking tools and equipment, and procedures for their safe use and maintenance
procedures for recording and reporting workplace information
‘Fit for work’ requirements, the impact of fatigue, and organisational policy and procedures for fatigue management
standards for height of a timber stack inside, under cover and in the open.
environmental protection requirements, including criteria for recycling and reusing material with faults and safely disposing of waste material.
