Operating a Diesel-Powered Machine Within an Enclosed Space at Brisbane International Airport

Project Overview

A contractor operating at Brisbane International Airport required a safe and compliant way to move diesel-powered equipment (an elevated work platform) through an enclosed area of the airport. With limited natural ventilation and workers operating nearby, there was concern around the build-up of hazardous diesel exhaust emissions — particularly carcinogenic diesel particulate matter (DPM).

The client approached RVT Group seeking a practical engineering control solution that would allow work to continue safely while reducing airborne diesel fumes.

Challenge

The enclosed environment presented several key risks and operational challenges:

• Diesel-powered machinery needed to travel through the space as part of ongoing operational works.
• Exhaust emissions had the potential to accumulate quickly due to restricted airflow.
• Workers, nearby personnel and airport visitors required protection from harmful diesel fumes and particulate exposure.
• The project team needed a compliant solution that would minimise disruption while allowing operations to continue efficiently.

With increasing industry focus on diesel particulate exposure and workplace air quality, the client required a proven hazard control measure that could be deployed quickly and effectively.

Solution

Following consultation with the client, RVT Group recommended the implementation of a specialised RAVEX® Diesel Particulate Filter (DPF) system to reduce exhaust emissions directly at the source.

The filtration system was selected to:

• Capture hazardous diesel particulate matter before it entered the enclosed workspace.
• Reduce visible diesel smoke and harmful airborne contaminants.
• Support safer operation of diesel-powered machinery in a restricted-airflow environment.
• Assist the client in maintaining a healthier and more compliant worksite.

RVT Group’s Technical Consultants worked closely with the project team to ensure the solution integrated effectively with the equipment and operational requirements of the airport environment. We also provided a MONITEX® Area Gas Monitor to ensure carbon monoxide levels were minimal.

By implementing a diesel particulate filtration solution, the client was able to:

• Continue moving equipment safely through the enclosed area.
• Significantly reduce diesel exhaust exposure risks for workers and nearby personnel.
• Improve overall air quality within the workspace.
• Maintain operational continuity while prioritising health and safety.

The project demonstrated the importance of controlling diesel emissions at the source when operating machinery in enclosed or poorly ventilated environments.g consistently clear effluent suitable for controlled discharge in line with environmental and regulatory expectations.
