On  the 13th  we went to sullom voe I learned that you have to go through security to get into sullomvoe  just in case  a person gets in and puts the  gas tanks on fire  and it will cause a huge fire  and it could  cause an explosion. People could get hurt. I learned what a electric  fire extinguisher looked like it has a black strip around the  top and a normal  one is  plain red I also learned that if you  put  Water on electic fire you will get electricuted.  In the control  they were lots of  computers.We went to the canten I had beef mince and tatties we put our  trays on a carousel  after lunch we went to  Sellaness   in sellaness  we saw the pollution unit and we saw skimmers the skimmers were made to  get the oil out  of the water.
