Are you unpacking, inspecting or fumigating shipping containers?

Stay safe – Avoid exposure to harmful gases

Hazardous gases are often emitted from seemingly harmless goods or may be a result of fumigation. Accumulation during transport may present harmful levels upon arrival.

The CTU Code of Practice states “…any CTU should be ventilated before allowing personnel to enter, preferably by mechanically forced ventilation” (ILO/IMO/UNECE §12.1.6).

Using the Evaqvent method, you will ensure safer work environment in a cost-effective way.

Evaqvent pre-ventilation

Easy, fast and efficient

Advantages using the Evaqvent method:

  • Easy to handle.
  • Ventilation before opening the container saves time.
  • Harmful gases are reduced by at least 80% in one hour.
  • Faster ventilation than using open doors, particularly in tightly packed containers.
  • The initial high peak exposure when doors are opened is eliminated.
  • Extracted air is evacuated to the outside.
  • No contamination inside the warehouse.

The videos below show two ways to position the Evaqvent suction plate over a corner vent. It is held in place by the vacuum created by the extraction turbine. The turbine must be positioned in a dry place, normally inside the warehouse, in a protective cabinet or in the optional mini trailer.

The videos show two ways to position the Evaqvent suction plate (patent pending) over a corner vent. It is then held in place by the vacuum created by the extraction turbine. The turbine must be positioned in a dry place, normally inside the warehouse, in a protective cabinet, or in the optional mini trailer.

We provide all you need to get started

Basic parts;

  • Evaqvent suction plate (patent pending)
  • Extraction fan
  • Sampling probe
  • Differential vacuum meter
  • Suction and exhaust hoses

 Optional parts;

  • Carbon fiber telescopic kit. This kit is used when the suction plate is positioned from the ground as shown in the second video above. The kit is here shown the with the suction plate for clarity.
  • Mini trailer that will hold all items during storage but also serves as weather protection during ventilation. Suction and exhaust houses are routed through the open tailgate. It is only 140 cm long and can easily be moved manually. In Sweden it is delivered registered for legal road speed 80 km/h.

Based on solid research

We investigated randomly selected containers arriving in Sweden and identified nearly 50 chemicals in the container air. One out of eight containers had levels above the occupational exposure limit and many had cancer-causing chemicals far over the limit. The figures are likely higher in warmer climates.
