Definitions
Breakdown equipment refers to the headrig saw centre and accompanying conveying
systems which may be manual or semi-automated.
Corrective action may include actions such as communication to management,
communication to on-site technical person, communication to off-site technical
support person, cleaning, communication with maintenance staff, recalibration, or
changes made to the operating system in accordance with worksite documentation.
Worksite policies and procedures refer to documented policies and to documented or
other directions provided to staff. These include, but are not limited to, ways of
managing health and safety, environmental considerations, quality, and production,
and must conform to legislation. Examples include standard operating procedures,
company health and safety plans, on-site briefings, and supervisor’s instructions.
