Marking up an Emergency SMB
There is a standard protocol in tech diving for certain DSMB colours to be used for notifying surface support (land or shore based) of whether life is peachy or if help is needed. In Europe Orange /Red is good and Yellow means assistance. A lot of USA operations are reversed. It doesn’t really matter to me as long as the protocol is pre-agreed with surface support beforehand and everyone knows what’s expected.
Configuring the Orange should be easy. Choose a DSMB as per our video here https://www.youtube.com/watch?v=eBJD1ubMd08&list=PLQdtd4uMGwGVCbJ-VWSBYPbPDbdw7HqgE on choosing and launching an SMB, and then for the Orange or non emergency, write your name on it.
For the emergency there are a couple of things you can do to make your life easier and reduce launch time and stress levels in case of emergency.
- Write your name and help on the top – both sides of the SMB
- Cable tie a wetnote as per the illustration to the top. Make sure its secure. A piece of duct tape over the top of the wetnote through which the hole is punched adds a lot of strength.
- Note gases that you most commonly use and that the skipper or you have got made up as either drop sets or ready for a diver to bring down.
- Make sure the skipper and surface support is briefed on checking the note if they see a yellow SMB and that they are setup and capable of responding as requested
- The ‘other’ section is for you to write anything extra you need. If you have one of those clear pockets on the smb, stick a pencil in it so you don’t need to look for that when deploying.
The Keep it Simple principle applies.
Least number of actions, performed simply is best. That’s why you don’t pre tie the smb to a reel or spool – in case you have to take off one and put on the other or take off and send up an existing line.
