Tsunami warning system. A tsunami warning system (TWS) is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas.
The law also requires nursing facilities to maintain medical records for each patient. The records must be kept for seven years after the patient is discharged from the facility. If the patient is a minor, the records must be kept for one year after the patient reaches the age of 18, but for at least seven years.
Unless another OSHA rule specifically provides a different period of time, you must keep the following: 1  Employee medical records for at least the duration of the employee's employment plus 30 years, except for Health insurance claims records that you maintain separately from your medical program and its records.
