Alarm systems have proven to be very effective in alerting people to potential dangers in their environment whether in the home or workplace. For example, a fire alarm which goes off on the detection of smoke enable people to evacuate a building and the fire department to be called in to contain the situation.
Plans for evacuation and shelter in the event of a disaster cannot be underestimated. For example, the evacuation of people living near and around nuclear reactor sites or chemical plants should be planned for.
Regular inspection by licensed inspectors, of man-made structures goes a long way in helping determine whether those structures are still durable and reliable. For instance, regular inspection of old architectures like buildings and bridges enable us see warning signs about a potential disaster and take steps to stop it.
Implementation of a fail-safe mechanism recognises potential failures in system designs and protects against such failures resulting in a fatality.
