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.
Medical records must be retained for seven years for adults. For minors, the medical record must be retained for seven years or two years past the time when the minor reaches the age of majority, whichever is longer. All medical records are the facilityâs property, and may be removed from the facility under very limited circumstances.3.
