Case Study

Diesel Emissions Kept Under Control During Emergency Water Mains Repair

Infrastructure

Exhaust fume mitigation in a small basement car park during emergency repairs.

When a leaking water main required emergency repairs, M Group were trusted to carry out vital works.

Challenge

As the leaking 48" trunk main was in a small basement car park with limited access to fresh air, extra care would need to be taken to ensure hazards were controlled and worker health was protected.

Works required a 5 tonne excavator and two diesel pumps, all of which were emitting diesel particulate and toxic gases whilst in use. With minimal access to fresh air to dilute harmful particulate, M Group recognised the need for hazard controls and jumped into action.

Solution

RAVEX® Diesel Filter Kit M30

A small, magnetic exhaust filter to the captured 99% of particulate at the source.

RAVEX® Diesel Exhaust Fume Extraction Kit

Diesel pumps had a high temperature fume extraction system fitted to capture fumes at the source whilst a powerful centrifugal fan forced harmful fumes away from the work area.

VENTEX® Axial Fan 450M

Ventilation was supplied to force fresh air from outside, deep into the space where works were taking place to dilute any remaining harmful particulate and provide a constant flow of fresh air to workers.
