    Level 4 Credits 10

    Purpose People credited with this unit standard are able to: explain

    fundamentals of wood veneer drying; operate and maintain a

    wood veneer dryer; and monitor and control the performance of

    a wood veneer dryer for laminated veneer lumber (LVL) and

    plywood manufacture.

    Plywood Manufacturing

Available grade Achieved

Explanatory notes

    1 The following apply to the performance of all outcomes of this unit standard:

     a All work practices must meet recognised codes of practice and documented

    worksite health and safety and environmental procedures (where these exceed

    code) for personal, product and worksite health and safety, and must meet the

    obligations required under current legislation, including the Health and Safety in

    Employment Act 1992, the Resource Management Act 1991, and their subsequent

    amendments.

     b All work practices must meet documented worksite quality management

    requirements. This includes the recording (by electronic or non-electronic means)

    of activities, events, and decisions.

     c All communications must be made in accordance with worksite procedures for

    content, recipient, timing and method.

2 Definitions

    Preventative maintenance refers to the care and servicing of equipment and

    machinery. This may include periodic checks and inspections, testing,

    measurements, adjustments, or parts replacement as required in accordance with

    worksite policies and procedures for the purpose of preventing faults or failures and

    to maintain production requirements.

    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.

    policies and procedures.

    1.2 The operating parameters and capability of veneer dryers are explained in

    accordance with worksite policies and procedures.

    Range may include but is not limited to temperatures, throughput

    speeds, veneer moisture content, redry rate.

    1.3 Operating components and process controls of veneer dryers are identified, and

    their purpose is explained, in accordance with worksite policies and procedures.

    Range may include but is not limited to transport system, heat transfer,

    temperature controls, venting system, moisture content readers,

    cool down section, distributed control system.

    1.4 Hazards associated with the drying of wood veneer are identified, and the role

    of protective equipment and safety features is explained, in accordance with

    worksite policies and procedures.

    Range hazards may include but are not limited to toxic gases, steam,

    heat, confined space, flash points, explosions, moving machinery;

     safety features may include but are not limited to personal

    protective equipment, hold cards, lockouts, stop buttons, guards,

    fire detection and prevention systems.

    1.5 The consequences of non-conformance of veneer drying with worksite

    standards are described in terms of equipment damage, production loss, and

    personal hazard.

Outcome 2
