Gas Measurement

It is not uncommon that containers arriving from overseas contain fumigants and/or production gases in concentrations exceeding the “Maximum Allowable Concentration” (MAC-value). As a consequence these gas concentrations can damage health either through one or repeated exposures.

It is difficult to predict the presence of residual gases as it depends on factors such as the fumigant used, the fumigation process, the materials and production processes used to manufacture the cargo.

EWS can monitor the levels of residual gases and can ventilate containers when concentrations exceed allowed limits. Once the residual gases are removed we declare the container “Gas Free” and issue a gas monitoring report that includes gas concentration levels detected.

Ventilation by means of natural airflows by simply leaving container doors open can take days. Forced ventilation is an economical choice as it reduces the time necessary to remove high concentration of residual gas. EWS uses patented NORDIKO VENTILATION & GAS RECAPTURE SYSTEMS
