The amount of chemical cargoes transported across oceans increases every year and results in the constantly growing awareness of the demands for developing safe and effective spill response arrangements. However, noting the significantly varying physical properties of chemicals and their behavior once they are spilt, and taking into account the potential effects of the chemical spills to the human health and environment, these preparedness and response arrangements are normally more complex in comparison to the arrangements in case of oil spills.
The present publication will provide all interested parties with brief introduction to the major issues concerned with the response to the chemical spills from ships; it is also intended to address the wide range of the common hazards associated with this type of spills. The authors of the booklet have paid particular attention to the behavior of the spilt chemicals in the sea water and reviewed possible response options.
In fact not all chemicals must be treated as hazardous - this term refers only to the so-called HNS, standing for the hazardous and noxious substances. When introduced into the marine environments, e.g. as a result of a spill, they are likely to create significant hazard to human health, marine environment, living resources, damage amenities etc.
