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

It is essential in this unit that competence be demonstrated in:

applying personal safety principles

interpreting atmospheric conditions using atmospheric monitoring equipment

recommending appropriate action

maintaining monitoring equipment

Consistency in performance

Evidence should be gathered over a range of variables, all using different types of monitoring equipment

Context of and specific resources for assessment

Context of assessment

A demonstration activity using workplaces/atmospheres with detectable but safe levels of contaminants should be used

Specific resources for assessment

For the demonstration of competence in this unit it will be necessary to provide a real life environment and/or simulations based on possible incidents. This should be done with access to a range of personal protective clothing and equipment, range of detection equipment as well as suitable simulation and/or sites.

Underpinning knowledge may be assessed through written assignments, and observation at simulated incidents

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.

Required Skills and Knowledge

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

Required Skills

Don, operate in, decontaminate and remove personal protective clothing and equipment

Analyse and communicate results of sampling

Required Knowledge

use and limitations of protective clothing and equipment

risk assessment

applicable exemptions for emergency services

purging agents

common chemical asphyxiants including: hydrocarbons, carbon dioxide, carbon monoxide, hydrogen cyanide, and hydrogen sulphide

common irritants and corrosives including: chlorine, ammonia and acid bases

common flammable gases including: acetylene, petroleum, methane, ethane, propane and butane

narcotics

(explosive range, upper and lower explosive limits)

exposure standards (time weighted average, short term exposure limits, peak limitation values, examination of toxic effect at the level of a range of flammable gases

conditions under which atmospheres become hazardous

organisational procedures for entering hazardous atmospheres

toxic effects on humans exposed to commonly encountered combustion gases

units of measurement used to express concentration of atmospheric contaminants (mg/cubic m. ppm, % v/v)

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.

Working environment may be

hazardous, unpredictable, subject to time pressure, chaotic and expose responders to risk, on land or water, by day or night

Safety information and procedures must include

relevant legislation, Australian Standards, codes of practice, manufacturer's instructions and organisational procedures

Procedures may include

safe working

permit entry plan

entry testing procedures

appropriate rescue and first aid plans

risk management

measurement

computer plume modelling

Response situations must include

confined spaces

enclosed and partially enclosed spaces

and may also include

storage tanks, silos, pits, pipes, shafts, ducts, transport vehicles and ships

obstructed entry/exit points

low visibility or lack of illumination

unsound or insecure structures

single and multi agency response

Equipment must include

breathing apparatus, chemical protective clothing and equipment, portable instruments, radiation detectors, sampling tubes and pumps, oxygen level meter, carbon monoxide detector and combustible gas detectors

Workplace atmospheres may

include visible and invisible hazards

include hazardous surfaces

range from safe to unsafe

Incidents may include

all fire, Hazmat or rescue incidents
