A membrane having means for indicating rupture or breach thereof, the membrane comprising:a) a plurality of first microcapsules each having a shell and encapsulating a first effector component;b) a plurality of second microcapsules each having a shell and encapsulating a second effector component which is capable of reacting with said first effector component to form a lytic agent; andc) a plurality of third microcapsules each having a shell and encapsulating an indicator substance;whereby, when said membrane is ruptured, at least one of said plurality of first microcapsules is caused to release said first effector component, and at least one of said plurality of second microcapsules is caused to release said second effector component to form a lytic agent to dissolve the shell of at least one of said plurality of first microcapsules and of said plurality of second microcapsules, and of said plurality of third microcapsules.
