Talk Overview

Over the last five years Chris Davis has worked tirelessly to improve the awareness and health practices of miners in Australia by persuading others to reduce the amount of very fine carbon particles in the underground air. Managing micro particles goes beyond mine ventilation, it is an emerging issue for awareness in all work and social environments where micro particles impact on air quality.

  • The WA Mines department (DMIRS) led the world’s biggest survey of nano diesel particulates in diesel fumes in an underground mine and their effect on miners’ health.
  • This led to the Western Australian government bringing forward legislation to lower the amount of carbon allowed in the underground air and tightening monitoring. The NSW government has already implemented similar legislation.
  • At least one equipment manufacturer has changed their equipment to emit less carbon particles.
  • Filter suppliers are making available filters that are 100 times better than previous (and still sold) filters.
  • Some mining companies understand that they can improve the breathed environment of their workers for no additional cost.

‘DPM is the next Asbestos’. In 2012 diesel emissions were classified as a Class 1 Carcinogen by the World Health Organisation, which is the same classification as asbestos. Carcinogenic pollutants have no harmless dosage, ideally zero is the target.

As diesel engines have evolved to become the highly efficient machine that they are today, they have created a huge problem. The problem being engines now produce particulate matter well below 1-micron diameter, these particles are now small enough to reach the alveoli. Nanoparticulate (50-1nm) are fine enough to translocate through the subtle respiratory membrane.

Aletek supply diesel particulate filters to suit all makes and models. DPF’s can be designed in varying configurations including; Wall Flow (>99%), Partial Flow (<66%) and active regenerating systems. All housings are designed, engineered and manufactured in house, in addition to Canadian manufactured cordierite substrates inserted.

Aletek is Australia’s leader in providing innovative solutions for the mining, oil & gas, transport, construction & marine sectors.
