Case Study Overview

Hazard control is vital during all works, but especially when those works are taking place in sensitive environments, such as food production plants. Airborne hazards produced during construction or repair works where no hazard control is in place can leave products contaminated. To avoid this and the shutting down of production during works, effective hazard control must be in place.


A food manufacturing plant on the outskirts of London required emergency floor repairs. However, activities involved in these repairs would generate large amounts of airborne dust. Adequate dust control measures needed to be put in place so that food processing could continue without risk of contamination. Therefore, RVT were approached for a solution.


RVT conducted a site survey to correctly assess the hazard and provide the best possible solution.

The contractor had already contained the area with a temporary enclosure, so RVT decided to install an extraction system that would give the client full assurance that there would be no food contamination.

By using a Ventex® 300CF & Wandafilta within the contained area, RVT effectively captured the dust at source and created a powerful negative pressure that ensured zero dust migration to the live production area. Multiple air changes per hour were also provided within the enclosure for the comfort of the workforce, as this was an exceptionally hot area of the factory.

RVT's extraction and HEPA filtration solution, meant that the food manufacturing plant could continue normal operations during works without fear of contamination.
