Harmful chemicals in arriving containers

An estimated 250 million shipping containers are unpacked in the world every year, requiring approximate 260,000 man-years. Unpacking or inspecting shipping containers may cause involuntary exposure to many types of harmful chemicals, emitted from the goods or added for fumigation purposes. Due to the limited natural ventilation in closed containers, accumulation in the air will occur during transport and may have reached harmful levels upon arrival. 

Our solution

evaQvent AB has developed a method and tools to facilitate pre-ventilation of shipping containers before opening and unpacking or inspecting their contents. Our specially developed evaQplate (UK patent pending) is simply connected to a dedicated extraction turbine. Turn on the turbine and position the evaQplate over one of the corner vents of the container. The arrival concentrations of harmful levels of chemicals can be reduced by 90% within 4 hours, often faster.

Our ventilation package

All you need to get going. An extraction turbine, our evaQplate suction plate, a differential vacuum meter to check for taped vents and monitor vacuum inside the container. A gas sampler probe to facilitate vacuum and gas measurements. It is inserted between the rubber seals between the doors as shown in a picture below.  Hoses are ordered in required lengths depending on how close the extraction turbine is positioned, typically between 5 and 25 meters. Long hoses are supplied in 5-meter sections with easy to use screw connectors.

Our research

We have investigated several hundred randomly selected containers arriving in Swedish ports and distribution centers. We identified close to 50 different chemicals. About 12% of all containers had levels in the air of harmful chemicals above the occupational exposure limits and 4% had carcinogens over the limits. The figures are likely higher in warmer climates.
