How Diesel Particulate Filters Can Help You Meet New Amendments by Ontario Ministry of Labour

There has been some proposed amendments recently to the Occupation Health and Safety Act. With new equipment and safety standards coming out, it is necessary for the laws to reflect that.


The Ontario Ministry of Labour recently came out with a proposed amendment to the current Occupation Health and Safety Act. The amendment is currently making rounds across the industry, as experts and operators are asked to comment on it.


Many mine owners and industry experts believe that this amendment was long overdue and will simplify the work they put in. But, is their current equipment up for the change?




Overview of the Amendment


The new amendment suggests and recommends the following:

  • Amend or add the requirements related to independent conveyances, ventilation, explosives for security, equipment for mine hoists, eye wash facilities, ladders positioned on the surface and emergency showers. The updates should also reflect on how electronic devices are used within the mines to assist in drilling and blasting.
  • The amendment is set to include basic recommendations from the Safety and Prevention Review Department, the Mining Health Department and other forces related to airborne hazard management, change management, seismic monitoring, supervisors of unremedied dangers and much more.
  • The amendment will continue to modernize all regulatory requirements and make sure that all terminology and salient features are updated to manage mining requirements and updates.

What It Means for Miners


The proposal put forth by the department goes on to suggest that all undiluted NO2 emissions from the tailpipe should be 60ppm or less. Some mines do not report on their NO2 requirements, as older equipment that hasn’t been updated for a while does lead to higher NO2 levels.


The new proposal also updates the ground reality to set CO levels at less than 600ppm in all undiluted exhaust systems. Mining firms will find this a lot easier to meet since they already have scrubbers and DOC on underground equipment to remove over 90 percent of all CO.


Most mines are required to meet current regulatory requirements to keep DPM exposure for workers below 0.4mg/m3 over an 8-hr period. The proposed amendment looks to reduce this to under 0.12/m3 per 8 hours. This is a massive drop, and many mines will be caught napping here.






How Mammoth Helps



Mammoth is here to help, as our new and advanced diesel particulate filters allow mines to continue operations with their current equipment. Your existing equipment fleet can comply with this proposal by adding DPFs to them.


Call Mammoth to discuss how our machine-specific, direct fit emissions systems can bring you into compliance with the new proposed regulations and clean up the underground air quality.
