With more online ordering than ever and customers expecting goods to be delivered rather than picked up, warehouses and logistics centres have never been busier. From a health and safety perspective, this can cause problems when staff are sharing workplaces with vans, trucks and other fume-producing vehicles on a daily basis. Adequate ventilation in these centres is absolutely crucial.
The case study below demonstrates how Colt helped create a safe, healthy atmosphere for the staff at the DHL warehouse in Lincoln with a tailored fume detection and hybrid ventilation solution.
SCOPE: VENTILATION SYSTEM FOR THE DETECTION AND REMOVAL OF NO²
DHL is the world’s leading logistics company. With 380,000 people in over 220 countries they provide logistics services to help businesses cross borders, reach new markets and grow. The Lincoln DHL Service point operates as a hub for international logistics and as such is of significant importance to their UK and worldwide activities. With continuous movement of vehicles within the building, the risk to health arising from deteriorating air quality as a result of emissions in enclosed spaces are significant. Colt was requested to design a ventilation system which would monitor and detect the build-up of nitrogen dioxide in the air within the building produced by the delivery vehicles.
Care needs to be taken to ensure that ventilation systems for this type of application are designed in accordance with appropriate guidance and the latest regulations.
The fume extract solution Colt proposed used a hybrid ventilation approach comprising 5 no. Colt Tornado mechanical extract fans positioned in the North elevation, and 3 no. Colt Seefire natural louvred ventilators positioned opposite on the South elevation. Hybrid ventilation combines the strengths of both mechanical and natural ventilation approaches to ensure a specific amount of extraction is provided, balanced by fresh air, whilst minimising energy consumption. A Colt designed Control Panel with integrated battery backup provides complete control of the system, with 9 no. detectors to detect levels of nitrogen dioxide around the building.
