Container Fumigation

Sea containers will be shipped all over the world. To make sure pests of unwanted animals and bacteria don't stand a chance, containers will be fumigated with highly toxic gases, that usually attack the nerve system. Some gases are also used to prevent cargo from rotting. When sea containers arrive at harbors, the harbor workers should measure the air inside the container on these gases, before they open it. Every year people die, get wounded or disabled because of lack of safety.

Besides fumigation gases, there could also occur other air pollution in these containers :

   -    This polluted air could be released by the cargo that is shipped, like evaporating paint, leaking packages, wood or other biological freight.
   -    A chemical reaction could have taken place during the shipment.
   -    The packages of products that contains toxic content could leak, what can cause chemical and toxic vapours in the of the container.

The following gases can be encountered:
Methyl Bromide, Acetaldehyde, Ammonia, Benzene, HCN, Butylacetate, Chloropicrine, 1,2 Dichloroethane, Dichloromethane, Formaldehyde, Phosphine, Carbon Dioxide, Carbon Monoxide, Pinene, Styrene, Toluene, Trichloroethylene, Vinyl Acetate, Xylene, Hydrogen Sulphide.

For safe measurements inside fumigated containers, use the UNIPHOS™ Fumigation Container Probe.





Below you will find a list of toxic gases that have been encountered with all different kinds of freight. This list has been determined in association with container fumigation companies all over the world.

Toluene - PID 80 or higher
Styrene - LEL 5 or higher
1,2 Dichloroethane - Reading on pentane tube 800 ppm or higher
