PUADEFLS002B Maintain and fit helmets

Modification History

Not applicable.

Unit Descriptor

Unit Descriptor	This unit covers the competency required to maintain and fit helmets that are capable of housing communications equipment. Maintaining a helmet includes inspecting, testing, isolating faults, replacing or sending away for repair, cleaning and testing prior to placing the item back into service. Fitting a helmet includes adjusting the helmet to fit the individual because the item is not an off-the-shelf issue. Maintaining and fitting ancillary helmet equipment is undertaken independently of the helmet and consequently is not covered by this Unit of Competency.

Application of the Unit

Application of the Unit	The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package. This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a Unit of Competency.	Performance Criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the Required Skills and Knowledge and/or the Range Statement. Assessment of performance is to be consistent with the Evidence Guide.

Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Maintain helmet	1.1 Helmet is inspected for serviceability in accordance with standard procedures 1.2 Helmet is tested for serviceability in accordance with standard procedures and manufacturers' specifications 1.3 Identified faults beyond own authority to rectify are reported to supervisor and faulty helmet is quarantined 1.4 Unserviceable parts of the helmet are replaced to render helmet serviceable 1.5 Communication system components are tested in accordance with standard procedures 1.6 Helmet is cleaned in accordance with standard procedures 1.7 Helmet suit is presented for inspection by supervisor and work is not progressed until supervisor has completed inspections in accordance with standard procedures 1.8 Relevant documentation is completed in accordance with standard procedures
2. Fit helmet	2.1 Fitting process is explained to the participant so that optimal fit can be achieved through relevant feedback 2.2 Participant is measured to select appropriate size helmet 2.3 Components of helmet are adjusted to optimise fit 2.4 Helmet fit is verified through participant feedback and supervisor approval 2.5 Relevant documentation is completed in accordance with standard procedures

Evidence Guide

EVIDENCE GUIDE
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessment must confirm the ability to correctly fit helmets to a minimum of three different people with no corrective action required by supervisor; to recognise limits of own authority; to recognise a range of faults including incorrect manufacture; and to correct a minimum of three unserviceable helmets. Consistency in performance Competency should be demonstrated over time with a range of different fittings and maintenance activities.
Context of and specific resources for assessment	Context of assessment Competency should be assessed in the workplace or in a simulated workplace environment. Specific resources for assessment Access to helmets, three live participants, ancillary equipment, tools and equipment for fitting and maintaining helmets.
Guidance information for assessment	Information that will assist or guide assessment will be written during Phase II of the Review of the PUA00 Public Safety Training Package.
