Our commitment

To work with industry to reduce serious accidents and incidents, and provide tangible support in achieving a positive cultural change.

Resources Safety’s focusSlide4

What is risk-based hygiene management planning and how does it relate to CONTAM?

4Slide5

Why the change from CONTAM?

CONTAMWas initiated to get sites conducting personal exposure monitoring for certain contaminants –

specifically dusts and

respirable

silica

Targeted contaminants known to be present or generated in the majority of Western Australian mining operations5Slide6

Was it risk-based?

CONTAM did not require the identification or investigation of exceedances, nor the implementation or effectiveness monitoring of controlsdidn’t allow for changes in mining operations and work populationsSEG formation

recognition of health hazards other than particulate-form atmospheric contaminants

*SEG = similar exposure groups

6Slide7

So what do we need to do now (May 2015)?

CONTAM will remain as a results database in the short-termOver the next 12 months, sites will enter their health- and hygiene-related data directly into the Safety Regulation System (SRS)7Slide8

What else do we need to do now (May 2015)?

Continue to use the financial year as your time gauge for sampling programsThat means, getting ready over the next month for the 2015-16 program8Slide9

Risk-based Hygiene Management Plan (RBHMP)

Termed management planning to align with the ‘principal hazard management planning’ of the proposed new legislationBeing risk-based means:non-prescriptiveits effectiveness is wholly based on the knowledge, competence, and commitment of the people involved in its development and implementation9Slide10

RBHMP is an opportunity to …

work out exactly what is going on in your workplacesWhat are your personnel actually and potentially exposed to?How are they protected (or not) from those exposures?What needs to be done for their protection in the short-term and long-term?How do you confirm whether you got it right (or not) in relation to control implementation?What do you have in place to continuously monitor and review?10Slide11

What is your role?

You have a choice – do it right the first time or don’t Worst thing you can do is to shirk your responsibility by going for something generic, and missing out on an opportunity to identify and manage the health hazards specific to your site11Slide12

Establish the goals

What does your site want to achieve from RBHMP?Where is your site in relation to its mine life and maturity of health and hygiene management?Role and responsibility identification Depending on the size of your site and its hierarchical structure, you might be doing all things, one thing, or nothing

Exposure assessment – Define SEGs

26Steps to defining SEGs:ObservationClassification by task and environmental agentClassification by task, process and environmental agentClassification by task, process, job description, and environmental agent

Classification by work teams

Classification by non-repetitive work tasks or jobsSlide27

Define SEGs

SamplingRelies on the review of previously collected data to classify the workforceRequires sufficient sample data and high degree of statistical confidenceOften difficult to do well, particularly where monitoring records are poor and information collected about the sampling environment is sparseA combined observation and sampling approach is the most PRACTICAL method of defining a SEG27Slide28

Exposure assessment – exposure profiles

Summarises and judges exposures to health hazards in the workplaceCombine information from the basic characterisation with the SEG informationExposure rating – use your site criteriaEstimate of exposure relative to the OELConsiders monitoring data, surrogate data, prediction 28Slide29

Results strategy

You have to know from the start what you are going to do in the event that:You receive an anomalous result or exceedanceYour baseline data confirms acceptable or unacceptable exposuresYour baseline data confirms SEG unacceptability Your maintenance data contradicts baseline32Slide33

SEG acceptability

Confirmation of SEG by statistical analysisReview and redefining the SEG where necessary33Slide34

34Slide35

Controls

The list provided in the procedure does not represent all health hazards and associated controls, and should only be used as an example… and what about monitoring and review?35Slide36

RBHMP approval, re-assessment and quota proposal

What do you do when you have generated a RBHMP document?When should you review and update it?And what about the sampling numbers?Contact MinesSafety@dmp.wa.gov.au if you need to know the answers to these questions36Slide37
