The telecommunications environment is unique because very few other jobs require such an attention to detail and accuracy performed in an expedited manner. Calls for Police, Fire or EMS response require precision and care. A wrong address, a missed word from the complainant as well as the failure to get pertinent information can spell disaster, not only for the success of the call, but may also pose a threat of potential liability for the department.
