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.
How long does an employer have to keep worker medical records? Unless another OSHA rule specifically provides a different period of time, you must keep medical records for at least the duration of the workerâs employment plus 30 years, except for: Health insurance claim records that the employer maintains separately from the employerâs medical program and its records.
