Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability:

identify laser safety issues, apply safe work practices and monitor and report on workplace incidents.

demonstrate knowledge of relevant work health and safety legislative frameworks

identify inspection tools and methods appropriate to the workplace

demonstrate the application of the principles and practices of work health and safety when working with lasers

identify intervention points for advice to assist in work and to guide problem solving

Consistency in performance

Evidence for competency in this unit must be gathered over time and across a range of workplace or simulated situations.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or under conditions that accurately simulate a realistic workplace in accordance with all relevant legislation and organisation requirements.

Evidence should be gathered while observing the individual working with lasers in an actual or simulated workplace. A record of all relevant reports, interviews and tests should also be submitted as evidence for assessment.

Specific resources for assessment

There are no special resource implications for this unit.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Required Skills

access, read, interpret and apply information on laser operations

identify laser sources

Required Knowledge

work health and safety (WHS) requirements relevant to laser emissions in the workplace

organisational policy and standards relevant to laser operations emissions

Range Statement

The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the Performance Criteria is detailed below.

Extended source viewing

Irradiance and radiant exposure

Point source and intrabeam viewing

Specular reflections

Use of magnifying optics

Laser safety controls may include:

Establishment of nominal ocular hazard areas (NOHA)

Exclusion zone/specification of laser hazard areas

Maintenance of a laser register

Protective eye wear specified in accordance with perceived laser threat

Use of interlocks to prevent inadvertent discharge of laser when safety features are not in place

Use of keys to activate laser

Warnings to avoid observation of source

Laser warning signage may include:

Labelling/signage on equipment

Notification of responsibilities and provision of safety information

Warning signage/notices surrounding exclusion zone or work areas where lasers may be operating

Laser exposure situations may include:

Laboratories, medical and dental clinics where laser equipment is in use

Maintenance workshops

Military training and field operations where laser devices are in use

Personal protective equipment may include:

Protective clothing

Specific eye protection goggles

Incident reporting may include:
