Scope of Work:

(a) Hygiene Monitoring Program

(i) Occupational Hygiene Monitoring is required at MRM as per the Health and Hygiene Monitoring Procedure (HHMP).

(ii) The Contractor is to deliver this monitoring programme over a period of 4 years (2024- 2028). Similar Exposure Group (SEG) distribution and sample requirements will be provided by the Principal.

(iii) The Contractor must provide an Occupational Hygienist or an experienced Occupational Hygiene Technician (Technician to be approved by the Principle’s Representative) to conduct all on Site monitoring for airborne particulates, vibration and noise. These must be conducted while the personnel monitoring equipment is in the field during the scheduled monitoring campaign and must be directed by the Principal.

(iv) The Contractor must be on Site for roster cycle of a 5-day swing per month to achieve monitoring targets. Two (2) additional days are allowed for travel (excluding Perth). This totals 84 days per year. Any additional days required must obtain prior approval from the Principal’s Representative. One (1) full day is allowed at the Commencement of the Contract for the Contractor’s Personnel to attend the Site-specific inductions for metallurgy and mining, which is included in the Contract Price.

(v) The Site safety coordinator must provide guidance and approve the monitoring plan for each monthly campaign. This must be discussed and confirmed on the first morning of the Occupational Hygienist’s Site visit.

(vi) The Contractor must use the Principal’s owned equipment for the collection of data including:

(A) Dust pumps (x5)

(B) Noise dosimeters (x5)

(C) Sound Level Meter (x1); and

(D) Associated calibration equipment and software.

(vii)The Contractor must ensure that hygiene monitoring equipment is within calibration date and in a serviceable condition to function correctly. Any issues are to be reported to the Site safety coordinator.

(viii) Monitoring consumables (filters, sampling heads, tubing etc.) must be provided by the Contractor. Hygiene monitoring equipment can be hired from the Contractor with prior approval by the Principal’s Representative.

(ix) The Contractor must package and send all samples to a National Association of Testing Authorities (NATA) accredited laboratory for analysis. The lab report must be provided to the Principal’s Representative on receipt.

(x) On Site supervision and transportation of the Contractor’s personnel will be provided by the Principal.

(xi) A sample tracking spreadsheet and a quantitative and qualitative results spreadsheet will be provided by the Principal. The Contractor must use these spreadsheets to track samples and results. A live version of these spreadsheets must be available to the Principal and the Contractor via an online file hosting service or similar. The Contractor is to facilitate this.

(xii)All data entry (other than laboratory results) must be completed during the allocated Site time.

(xiii) All Occupational Exposure Limit (OEL) exceedances will be managed by the Principal. The Contractor must alert the Site safety coordinator by phone or email on receipt of lab results showing exceedances.

(xiv) The Contractor is to provide monthly updates of progress in a detailed executive summary report. All laboratory results from monitoring must be provided in this report to allow the Site safety coordinator to interrogate data and deliver information to internal stakeholders. Reporting must consist of:

(A) air contaminant database

(B) laboratory reports

(C) noise dosimetry database

(D) noise download reports

(E) feedback letters

(F) notification of exceedances.

(xv)At the completion of the monitoring programme, the Contractor must provide a statistical review of results and a full review of the programme, including recommendations for inclusions and exclusions for ongoing monitoring.

(xvi) The Principal will provide personal hygiene monitoring results and feedback to all monitoring participants.

(xvii)The Contractor must provide monthly monitoring reports for distribution around Site.

(xviii) Whilst conducting hygiene monitoring on Site, the Contractor is reportable to the Site safety coordinator.

(b) Annual Statistical Review

The Contractor is to provide annual reviews in a full report to the Principal. This report is a statistical analysis of the monitoring program data across the year.

(c) Human Vibration Survey Whole Body Vibration (WBV) and Hand-Arm Vibration (HAV) The objective of the survey is to:

(i) Measure WBV exposure experienced by the Principal’s personnel within the Similar Exposure Groups (SEGs) where there is a risk of exposure due to mobile equipment or fixed plant

(ii) Measure HAV exposure experienced by the Principal’s personnel within the Similar Exposure Groups (SEGs) where there is a risk of exposure due to hand tools

(iii) Identify the Similar Exposure Groups (SEGs) who are at a high risk of adverse health effects due to long term exposure to whole-body vibration or hand-arm vibration. New SEGs may need to be identified from the previously identified SEGs.

(iv) Identify items of equipment and processes contributing to high vibration exposures in personnel or SEGs; (v) Develop a WBV or HAV exposure profile for SEGs for the various types of mobile equipment used at the operations

(v) Where there is a risk to health from exposure to WBV and/or HAV,

(vi) Provide suitable recommendations for control;

(vii)Provide a draft operational procedure and presentation for initiating a discussion within the business to address the Human Vibration risk

(viii) To ensure a valid assessment is undertaken, representative items of mobile plant and hand tools are required to be surveyed

(ix) The assessment is to be undertaken against the Principal’s WBV and HAV performance requirements in the Principal’s Health Standard

(x) The site wide survey is to be conducted every 2 – 3 years at a time agreed with the Principle

(d) Annual Respirator Fit testing

(i) The Principal’s personnel have designated environments requiring respiratory protection, as per legislative requirements within AS 1715

(ii) Face fit testing is a requirement of the Australian Standard 1715:2009 "Selection, use and maintenance of respiratory protective equipment", which ensures that the specifically selected respiratory protective device is suitable for an individual to use in specific environment with airborne contaminants

(iii) The Contractor must perform quantitative fit testing according to AS 1715:2019, using the TSI PortaCount Respirator Fit Tester on Site. The fit test includes training on the use of the respiratory protection, a fit test report and a fit test card for the Principal’s personnel to keep.

(iv) The Works are to be carried out over 3 cycles of 9/5 (9 days on, 5 days off) rosters at a time of the year agreed by the Principle to achieve the capturing of all candidates

(v) The Principal’s personnel are required to come to the fit-test clean shaven as per the requirements of AS 1715:2019. Where this is not done, the Principal’s personnel cannot be fit-tested, and the fit-test cost will be forfeited by the Principal. The Principal’s personnel are required to bring with them all facial/head PPE that would normally be worn to ensure they do not adversely impact on the Respiratory Protective Equipment (RPE). The Principal’s personnel are required to be prompt for their appointment and not have smoked within the 40 minutes prior to the fit test.

(vi) The Contract Price includes consumables for the instrument and a fit test on the 3M Aura 9300+ Series disposable respirator. If other disposable respirators require fit testing they must be supplied by the Principal, or the type should be advised to the Contractor 2 (two) weeks prior to the fit test to ensure the Contractor obtains the required respirators.

(vii)The Contract Price does not include the supply of reusable respirators. They are to be supplied by the Principal. Where reusable respirators are to be fitted, the type should be advised 5 (five) weeks prior to the fit test to ensure the correct adaptor is available. Where insufficient time is allowed to obtain the adaptor then relevant re-usable respirators must be purchased for modification, at cost +5%.

(viii) The fit test should be repeated on an annual basis or if the face shape changes, whichever is sooner.

(ix) Each fit testing event takes approximately 20 minutes to complete. This may be extended in cases where the Principal’s personnel must redo the test, due to personnel being asked to shave or does not turn up on time. However, 3 persons per hour can be used as a general guideline with respect to how many fit tests can be undertaken in a given day.

(x) It may be possible that an approved fit for disposable RPE is not achieved. If this is the case it may mean that a higher level of RPE may need to be assessed, such as reusable half-face or full-face RPE, or positive pressure RPE.
