Risk management is not a lifecycle process! I totally agree to this that company should take care of risk management not only in the beginning of the production but during entire time of the production. Biggest example of this is TATA Steel:

The metal giant was fined £1.98m after two workers suffered injuries to their hands in two separate incidents involving machinery. One lost two thirds of his left hand and his middle and ring fingers while trying to clear a blockage on a line manufacturing steel tubes, which had unsuitable guarding; elsewhere a team leader lost part of his little finger when his left hand was caught in a lathe.
