Conclusion: The 2nd Edition of the Mines Rescue, Gas Detection and Emergency Preparedness Manual was released in June 2014.
Conclusion: As a result of the research conducted the following outcomes have been achieved:
The device developed by Emission Reduction Products Engineering Pty Ltd (ERP) to collect a suitable sample from the gas sampling point appears to work, but further evaluation is required over a range of in-service vehicles.
Conclusion: The Coal Services Occupational Hygiene database is an invaluable resource. To improve the use and quality of reporting back to stakeholders we put forward an alternative standardised report which presents the sampling data in a more user friendly way.

Conclusion: The study established an acceptable EC correlation between data using the MAHA MPM-4M aerosol DPM analyser for samples collected from the manifold exhaust sample point and samples collected from the vehicle exhaust.
The study also showed an acceptable correlation between EC data using the MAHA MPM-4M LLS device and the NIOSH 5040 quartz filter analysis from samples collected at both the manifold and the engine exhaust.
The study also showed an acceptable correlation between EC data using the MAHA MPM-4M LLS device and the NIOSH 5040 quartz filter analysis from samples collected at both the manifold and the engine exhaust.
Although it was thought that a revised correction factor would be required for different engine types, this was not found to be the case based on the data produced from this study. Despite the fact that the sample size for some engine types was small, these engines exhibited a similar degree of variance in EC between the MAHA MPM-4M LLS device and the NIOSH 5040 quartz filter analysis to that of engine types with a larger sample size.
Based on the results of this research, the current correction factor used in LLS devices such as the MAHA MPM-4M requires updating from 0.46 to 0.65 when sampling from the exhaust and 0.67 when sampling from the manifold exhaust.
The ability to take samples directly from the manifold exhaust for EC analysis has advantages over taking samples from the vehicle exhaust. These include eliminating issues relating to water vapour in the sample, control over probe insertion and position and more realistic data in relation to engine emissions and condition prior to other devices that may be fitted to the engine.
There seems to be an unfounded perception within the coal mining industry that the accuracy of the LLS and other DPM devices that are currently is use is absolute. Given the equipment and testing variables that can occur during the routine EC and TPM engine testing, results will vary between operators. While an acceptable correlation between LLS devices and the NIOSH 5040 quartz filter analysis has been established during this study, the focus should remain with good engine maintenance and perhaps the adoption of EC value ranges as opposed to a specific concentration as an upper limit.
While a number of analysis outliers were evident from the results, the number was relatively small and did not impact on the overall findings.
The use of the ERP chamber vessel for engine manifold sampling and the Freudenberg sampling system for quartz filter sampling confirmed the observations by Dr Brian Davies in the 2013, Wollongong University, Coal Services Health and Safety Trust research as being suitable devices for this type of testing.
