Vehicle cabins are a critical control, isolating operators from harmful airborne dusts in the outside environment. To ensure cabins are protecting workers, they require regular maintenance. Generally, this involves regularly replacing seals, cabin filters and maintaining positive pressure within the cabin.
Currently, there is a shift occurring which is increasing regulation around cabins, focusing on improving the effectiveness of the cabin in filtering and reducing dust exposure.
Regulatory requirements for cabin air quality control
Regulation of cabin air quality has increased through 2020 and is projected to continue into 2021 as the International Organization for Standardization (ISO) is nearing completion and release of ISO 23875 – Operator enclosures — Air quality control systems and air quality performance testing.
The Standard provides requirements, best practices, and information to achieve sustained quality in the design, manufacture, performance testing, use, and maintenance of the operator enclosure air quality control system. In also includes information on control of airborne particulates in operator enclosures, along with recommendations are made for operational integration of the air quality control system.
It is anticipated that ISO 23875 will introduce requirements for the monitoring of cabin pressure.
ISO 23875 is expected to be released in early 2021, and introduce requirements for the monitoring of cabin pressure. This is anticipated to be similar to the requirements previously released by NIOSH and those incorporated in DIN EN 474-1: 2014 Earth-Moving Machinery – Safety – Part 1: General Requirements.
GCG will be monitoring the release of ISO 23875 and will keep you up to date with information as it is released.
Watch this space
Testing the effectiveness of seals and the air-conditioning system historically requires the plant to be parked up for additional maintenance time.
By measuring air pressure inside versus outside of the cabin, you can determine how effective the cabin is at controlling dust from entering the cabin. This is a recognised method that can replace traditional subjective cabin testing with an objective, real-time solution that informs planned maintenance.
GCG will soon be releasing a new service which supports our clients in meeting their requirements of the upcoming international standard and state-based legislation.
If you are interested in being involved in a trial of our new service please contact Adam O’Malley, GCG’s Senior Innovation Projects Lead via adam@gcg.net.au
Stay up to date with the latest in WHS and occupational hygiene news.
Real-time dust monitoring has really come into its own in the last few years. The ubiquity of real-time monitoring devices and the recent emergence of intelligent dust exposure control applications and platforms like GCG’s ‘Exposi’ system have taken monitoring and management of dust exposure to a new level. Hygienists and safety professionals now have the ability to make smarter, faster decisions around dust control management. Real-time hardware devices capture data…
Increased awareness of silicosis and other occupational lung diseases caused by exposure to hazardous levels of respirable crystalline silica has prompted employers and workers to seek ways to reduce the potential for worker exposure to hazardous dust. This has driven a rise in the uptake of dust monitoring technologies including Remote Real-time Dust Monitoring (Fixed Point Monitoring) in workplaces across Australia. In Australia, silicosis has been known to cause…
How can a work health and safety management system help my business?
A work health safety management system (WHSMS) A WHSMS is a systems-based approach to help companies manage their work health and safety risks and maintain compliance with current legislative requirements. What is a work health and safety management system? A WHSMS is a collective set of procedures, plans, and associated documents that align with business operations and support the process of managing workplace health and safety.
Is your WA principal mining hazard management plan up to date?
The terms and definitions used in reference to ‘principal mining hazards’ vary across Australia. In Western Australia new Work Health and Safety (WHS) laws and accompanying regulations came into effect on 31 March 2022, introducing a meaning for, and a list of, principal mining hazards (PMHs). While it’s likely your risk management framework already identifies principal mining hazards, they may not be addressed as comprehensively as…
What’s next on the journey to eliminate silicosis?
The re-emergence of occupational lung diseases across Australia, such as silicosis and coal worker pneumoconiosis, has received significant focus from industry, regulators, and unions alike. Since 2016, a series of government reviews, task forces, and parliamentary inquiries have identified gaps in hazard awareness, compliance, and regulatory frameworks relating to airborne dust. These documents also identify that preventing occupational lung disease is a complex problem to solve. Occupational…
