Some dangerous chemicals (hemicellulosis), with high vapor pressure, can develop concentrations of explosive gases (IPA=isopropanol) above the lower explosion level (LEL).
Such chemicals are traditionally transported in expensive reefer containers at low temperature.

The risk of exposition can be controlled using gastight bags treated with low vacuum, even in an no-cooled container.

Solutions & results
Hemicellulosis was packaged in vacuum liners and flushed with Nitrogen (N2). The atmosphere in the testing containers was monitored and registered during 45 days, which is the time that a transoceanic voyage takes.
No dangerous concentrations were found and after this trial two more containers were shipped from Antwerp to the USA. At arrival, the cargo was complaint with all safety security measurements. Overall result was a success and represented costs savings of more than 600€ per container.
