Custom-Made Spill Response Barriers

During the response to many oil spills in coastal or inland waters, the use of manufactured booms has often been supplemented by the use of devices put together by response teams in emergency situations.

In many cases, due to the site characteristics, the pollutant's behaviour or insufficient or even a complete lack of specific response means, responders build makeshift devices with
locally available resources to contain, deflect or trap the pollutant or to protect sensitive areas.
The efficiency of these custom-made barriers is highly variable according to the materials and techniques employed.
The use of custom-made barriers may therefore be considered, however these barriers should not be improvised in an emergency but rather should have been designed, tried and tested, as part of a response planning and preparedness effort.
 
The second section of this guide comprises practical datasheets for various custom-made barriers.
These datasheets present the deployment conditions, equipment required, benefits and limitations observed in the field for each type of barrier. This is in no way an exhaustive inventory of what could be imagined. On the basis of the
information presented and the many illustrations provided, readers will be able to determine the most appropriate equipment for the situation in hand, and then to assess the chosen solution during exercises.
 
This guide is mainly intended for public and private personnel in charge of spill response preparedness, but also for response teams, who will find practical advice on building devices that can then be adapted to the given situation.
