What information do you need to make decisions?


Think about these, too:

  • Defining the restriction area should be based on the updated HNS information on-scene. If results from the measurements are not available, information concerning the substance can be found in different databases and use of predictive tools, cargo information etc. What will you do to define the restriction area, if there is a question of several substances involved?
  • You are the SMC in your national MRCC. A vessel has given an emergency call due to a leaking chemical container. The crew of the distress vessel is safe, but the nature of the leaking substance is still not known. How do you command the SRU members to protect themselves before entering the distress vessel?
