Standards and Regulations

Air Quality Standards and Regulations nationally and internationally.

Air Quality Standards

 

Dust has a significant effect on the health, comfort and safety of workers and machines in mining, quarrying, construction and other adjacent industries worldwide. General working activities generate hazardous and harmful airborne particulates and gases.

Governments and working bodies have introduced standards of air quality to be maintained. These standards focus on cabin air quality to define design, performance, maintenance, operation and testing methods. These standards and regulations include the new international ISO 23875 standard released in 2021 and the Australian RS20, emphasising the air quality inside operator cabins.

The new ISO 23875 standard places a greater emphasis on the air quality inside the cabin than has been previously addressed.

ISO 23875:2021

One of the latest developments in regulations is ISO 23875 for the mining industry. BreatheSafe systems meets and exceeds this standards with our new INPRESS TS.

There are 5 performance requirements in ISO 23875

  1. Maximum sustained CO2 levels
  2. Maximum respirable particulate matter
  3. Speed of particulate matter filtration
  4. Minimum sustained pressurisation is 20Pa
  5. Maximum sustained pressursation is 200Pa

RS20

Dust control in Queensland surface mines.

Generally conventional HVAC systems are not adequate to handle high volumes of dust for long periods of time.

It is also likely that standard cabin filters do not sufficiently protect operators from airborne mine dust.

RS20 gives consideration to:

  1. Filtered air with minimum H13 HEPA filters
  2. Maintain pressurised cabin at minimum 20Pa
  3. Continuous monitoring of pressure with auto alarms for events
  4. Removing dust brought in by operators and use through return air filters and HEPA vacuum systems, with minumum H13 filters
  5. Ensure effective cabin sealing
  6. Design of operator cabin for ease of visibility to lessen need to exit vehicle
  7. Means of ensuring cabin doors remain closed, such as self-closing cabin doors.
  8. Covering seats in mobile plant with less porous materials to minimise the harbouring of dust.
  9. Design the cabin to minimise potential for dust accumulations. Position blowers / vents / outlets such that dust is not blown around the cabin (eg from floors).
  10. Shrouding to minimize latent dust build up above cabin doors

ISO 10263

Earth-moving machinery operator enclosure environment for HVAC.

Prior to the publication of ISO 23875, ISO/TC 127 (ISO Technical Committee 127 – Earthmoving Machinery), had published a standard series which also covered some of the same subject matter.

The performance requirements in ISO 10263

  1. Maintaining 50 to 200 Pascals
  2. Fresh airflow requirement of more than 43m3/hr
  3. 96% efficiency of external air filter
  4. Heating system with windscreen defrosting features
  5. Focus on airflow vs CO2
