ISO 23875 Standardises Mining Cabin Air Quality Control System Requirements. 

For more nearly 2 x decades, LSM Technologies has provided a "loud voice" advocating and contributing to the evolution of the ISO 23875 and other OH&S Standards.

The implementation of the ISO 2387 will provide:

  • Maximise protection of operators / occupants of enclosed fixed and mobile plant cabins from harmful dust particulate and fibre.
  • Increased operator comfort, reduce fatigue and increase concentration.
  • Extend HVAC Service life and reliability / efficiency.
  • Enhance Production and Machine availability.
  • Provide significant cost- downs in reduced maintenance. 

What is the ISO 23875?

ISO 23875 is currently a draft international standard, with the final standard expected to be published by Q4/ 2021.

The standard creates a consistent approach to designing, testing, operating and maintaining operator enclosures with respect to air quality in the mining industry. Adoption of the practices outlined in the standard protect personnel inside operator enclosures from harmful respirable particulates / fibre, through:

  • Maintaining safe levels of CO2.
  • Conducting routine performance testing of air quality control systems to maintain compliance, including testing. Cabin pressure, operating CO2 concentration, and Fresh and Recirculation Filtration effectiveness.
  • Performing preventative maintenance throughout the life cycle of the Cabin.

Life-cycle standard creates consistency across the life of a machine

A life-cycle standard follows a machine from the date that it is certified compliant - either at the factory or upon successful retro-fitting- ensuring compliant design, testing, and maintenance over time.

The standard promotes operational integration, bringing stakeholders together from different functional areas and seniority levels to focus on operator air quality and maintaining compliance

The benefits of ISO 23875- Health, Safety, and Trade Benefits

  • Reduces the incidences of lower-lung chronic health conditions of machine operators in the work force
  • Establishes requirements that can be consistently monitored, tested, and managed by industrial hygienists
  • Improves employee retention and recruiting by addressing a key environmental hazard, creating a safer workplace
  • Lowers equipment maintenance costs; HVAC system will run longer and more effectively with the reduction of particulate building up on the evaporator core
  • Defines maintenance practices and service intervals to maintain required Cabin performance
  • Creates consistent global standard and approach to Cabin air control systems, reducing impacts of regional regulations and multiple iterations of machines, platforms, and parts

Standardising Cabin Air Quality through Performance requirement- ISO 23875 Performance Requirements
The goal of an air quality control system is to protect a machine Operator from harmful particulates / fibre coming from the outside of the Cabin through filtration and Cabin pressurisation.


Support of ISO 23875 recommendations gaining traction around the world

  • ISO TC-82 Mining, Working Group 9 currently piloting elements of ISO 23875
  • Bringing OEMs, industrial health, mining companies, regulators, service and maintenance functions together to generate support and adoption
  • Additional industries revising standards to gain alignment with ISO 23875 (SAE, ANSI, EN) Gaining Acceptance from Stakeholders

**The US Occupational Health and Safety Administration has expressed significant interest in making ISO 23875 a normative standard in the OSHA silica rule, Table One”

Timeline and next steps

  • ISO 23875 is in the final stages of balloting and approval
  • International standard set to be finalised and published in Q4 2020 – Q1 2021
  • Leading working group currently piloting ISO 23875 installations for mining companies in North America, with
  • Installations set to begin soon in Australia, Africa, and Central America
