What is ISO 23875? New Cab Air Quality Standard

Workplace exposure to airborne dust is a critical issue for Australian mine sites. Exposure to asbestos, silica, coal and other respirable dust can increase occurrences of chronic lower lung diseases.

In addition to occupational health and safety (OH&S) factors, dust and debris can increase mining companies’ heating, ventilation, and air conditioning (HVAC) maintenance costs due to accumulation on evaporator cores, degrading performance.

To address these issues and the challenge of navigating multiple regional standards, ISO convened TC-82 Mining Working Group 9 to assess air quality system requirements in the mining industry.

TC-82 Mining Working Group 9 drafted a new international standard outlining air quality engineering and performance requirements, ISO/DIS 23875: “Operator enclosures – Air quality control systems and air quality performance testing”, expected to be published in early 2021.

ISO 23875 creates a consistent and international approach to designing, testing, operating and maintaining air quality in operator enclosures in the mining industry.

Working group chair and Sy-Klone International executive vice president Jeff Moredock was recruited following his involvement in the International Society of Environmental Enclosure Engineers (ISEEE), which focusses on operator enclosure air quality and standards development.

“It was exciting to see the global body of knowledge around operator enclosure engineering and performance testing come together in such a powerful way,” Moredock tells Safe to Work. “When adopted, this standard will make a huge difference in operator health and safety.

“The working group brought in stakeholders from over 10 countries to ensure we captured feedback and created a standard with global buy-in to guide the design and testing of air quality control systems.

“Bringing mining companies, OH&S officers and original equipment manufacturers (OEMs) together resulted in a collectively beneficial and uniform standard that would help protect operator health and facilitate increased trade around the world.”

ISO 23875 differs from past standards because it is a lifecycle standard, addressing cabin air control systems from the time of design, to when the equipment arrives onsite and throughout its operating life. ISO 23875 outlines specific engineering and ongoing testing to ensure compliance.

Sy-Klone International is well-positioned to help mining companies meet ISO 23875 requirements. As Sy-Klone vice president of marketing and business development Austin Browne explains, Sy-Klone helps Australian mining companies address dangerous respirable dust with its advanced heavy equipment cabin air quality systems.

“With over 30 years of experience and over 100 patents and trademarks in air filtration and precleaning, Sy-Klone is the world’s leader in heavy equipment air quality and control systems,” Browne says.

“Sy-Klone has an extensive global reach, working in the world’s most extreme environments. Sy-Klone’s leadership in air filtration and cabin precleaning has been recognised internationally, including via a recent award from the United States Centers for Disease Control and Prevention for the development of a smart cab operating system that blends internet-of-things-enabled sensor capabilities with Sy-Klone’s state-of-the-art technology in air quality systems.”

Sy-Klone’s RESPA system keeps dust and debris outside of operator cabins, allowing workers to breathe easy and stay safe on the job. The RESPA system includes a precleaner, pressuriser, high-efficiency filtration and an in-cabin monitoring system.

“Sy-Klone’s HEPA filters outperform the competition, delivering a higher filter efficiency, while maintaining needed airflow levels,” Browne explains.

“The Sy-Klone HEPA filter is 99.991 per cent efficient at 0.3 microns versus other HEPA filters evaluated at 99.97 per cent at 0.3 microns. This difference is meaningful. Sy-Klone’s filter can stop much smaller particles and prevent additional dust from reaching the operator cabin.”

United States-headquartered Sy-Klone has a team of Australian-based partners with in-depth expertise of the Australian mining industry: LSM Technologies and Lyons Airconditioning Services.

LSM chief executive and managing director Peter Woodford shares that with over 40 years of experience, his company, a Sy-Klone master dealer, has influenced Australia’s air quality knowledge, including by partnering with the Queensland Department of Mines and Energy to write a case study on occupational hygiene monitoring for airborne particulate matter.

“We have worked with mining companies across Australia to shape our country’s understanding and approach to air quality, installing Sy-Klone solutions that deliver cleaner air for machine operators,” Woodford says.

Lyons Airconditioning Services general manager Emmanuel Lardis adds that with 35 years’ experience in providing HVAC solutions to the Australian market, his team are Sy-Klone RESPA installation experts.

“My team has witnessed an increased demand for air filtration and air quality systems,” he says. “We have become experts in helping mining companies address the toughest dust issues through Sy-Klone RESPA installations.”

Former Rio Tinto chief advisor for industrial hygiene, Liam Wilson, was one of several hygienists who provided input to the working group on the new standard.

“The working group was active in trialling the standard in field applications to ensure it was written in a way that can be practically applied for either OEMs or operators,” Wilson explains.

Wilson shares how Sy-Klone’s products will help companies address the updated standard and control dust in operator enclosures in a better way.

“Sy-Klone is very proactive and continually evolves their technologies to effectively manage dust exposure inside operator cabins,” Wilson says.

To ensure an Australian perspective was captured, the working group engaged the Earth Moving Equipment Safety Round Table (EMESRT) and the Minerals Council of Australia to discuss future equipment design to meet the standard in Australia.

Aside from not wanting workers to become ill, mining companies are liable for insurance costs or workers’ compensation, so improved worker health offers both intrinsic value and cost avoidance potential.

“Prevention is better, and if a business can effectively manage and reduce dust, it’s stopping people from getting hurt at work and eliminating long-term costs to the business as well,” Wilson concludes.

Testimonials: OPTIMAX

What our customers are saying…

“We really like the OPTIMAX. We’ve gone from blowing the filters every second day and changing the filters once a week, to changing the engine filters every 300 hours, without ever opening the air filter housings to blow out the filters. The operators are really sold on the systems, and so am I.”

South Carolina Landfill Operations Supervisor

“We ran the OPTIMAX equipped Harvester next to the factory equipped Harvester during the wheat harvest and there was a very marked difference between how long the filters would go between cleanings. I was so pleased with the OPTIMAX that I installed one on the newer harvester at the end of the wheat season.”

T. H., Middle Georgia Farmer

“We got 60 hours of filter life with the factory installed tube body precleaner and 361 hours after we installed the OPTIMAX systems on the front and rear engines of our CAT 657 We changed the filter when the restriction light went on.

There were 361 hours on the last set of filters they changed out. This is a great improvement and will let you know when the next set are changed.

Updates:

Alan Winstead, Service Manager, Whayne Supply, Evansville, Indiana, USA

“I was a participant in the first field test of the OPTIMAX-AG. I didn’t know what to expect. When the filter housing was opened after over 40 hours of harvesting, I expected to see a lot of debris in the filter housing. What we found was shocking, there wasn’t any debris in the filter housing. The wheat chaff in our area contained a lot of black mold spores this year because of wet conditions just prior to harvest. These black mold spores were jamming up the filters in the other harvester. In the OPTIMAX-AG equipped machine, we were very surprised to see that the filter pleats did not have an accumulation of black mold, the machine owner commented, “it is doing something with the black mold?” as he looked at the filter with surprise in his face. He was right it was ejecting it before it got the filter”

D.M. Field Service Technician

“We have never seen a precleaning system that performs like the Sy-Klone OPTIMAX. With the recent change in engine design, our tube body equipped filter boxes were not performing as they had previously and we were getting significant customer complaints about our intake systems . . . it was simply not getting the job done. Not only have we restored our customer’s confidence in our intake system design but we have also saved money on our first fit installations with the OPTIMAX System. We would never have looked for a better solution had we not had this failure. It has turned out to be a Win-Win for our customer and for our company”

OE Engineer, Large Mining Equipment Manufacturer

“I have never seen anything that keeps the filters clean like this OPTIMAX. I am very skeptical; if it were not on my machine I would not believe it”

D.S., Machine operator

“We were blowing air filters out at least once a day and replacing elements every three days. Now we go 300 to 500 (hours) before replacing the elements, without blowing out the air filters.

Sy-Klone has provided technology that saves us money, increases our productivity and makes for happier operators.”

Landfill Site Manager, South Carolina

“The opportunity to participate in Sy-Klone’s field study for the OPTIMAX-AG and RESPA has been a real eye-opener for us. Running hard all day with cold air in the cab a fully powered engine, day after day, well we just did not think that was possible. We now have a new normal, we were unaware of the solutions available to us, and we really did not understand the problems we had. I have to hand it to Sy-Klone, their systems work”

D.S., Farmer

“The OPTIMAX® works really good! At the 250-hour service interval on the D6R we opened the engine filter housing to check the filter and it looked great. We reinstalled the cap and put the tractor back to work.”

Landfill Site manager, Louisiana
