Reconsider the lifting operations in Example 10.6, but consider the whole operation including the worker onboard the ship, the crane operator, and the worker on the quay who positions the containers and removes the hooks. Note the assumptions you have to make to carry out the analysis. (a) Break down the job into a sequence of tasks and list the tasks in the sequence they have to be done. (b) Carry out a JSA and record the results in a suitable JSA worksheet.
A number of heavy containers are to be lifted from a ship to a quay. The containers are lifted by a large crane. A worker attaches four hooks to each container. To attach the hooks, he has to climb a portable ladder, fetch a hook, and attach it to the container. The hook is rather heavy, and the work position is awkward. It is therefore easy to get back problems. It is further possible to crush fingers and hands between the hook and the container. When the hooks are attached, the worker signals the crane operator to start lifting the container. During this operation, the container may swing and hit the worker. Other hazards are related to falls on the same level and from the ladder. Consider a hot water kettle that is used to make hot water for tea. Choose a model you are familiar with and carry out an FMECA analysis of the kettle.
