PUAFIR307B
Monitor hazardous atmospheres

Assessment tool

Version 1.0
Issue Date: May 2024


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.

This unit covers competence in monitoring atmospheric conditions to measure contaminants, interpret readings, recommend action to take based on the interpretation, and the effects on humans exposed to hazardous atmospheres.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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)

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
