Washington Self-Insurer Accident Report (SIF-2) is a form used by employers and their insurers to report workplace injuries and illnesses that are covered by the Washington State Industrial Insurance Act. It is used to report the incident to the Department of Labor & Industries (L&I) and to collect information about the injured worker, the incident, and the employer. The SIF-2 form includes two types of reports: the initial report (SIF-2A) and the follow-up report (SIF-2B). The SIF-2A initial report is used to notify L&I about an accident or illness, and must be completed within seven days of the incident. The report includes information about the employer and the injured worker, as well as details of the incident, such as date, location, and type of injury or illness. The SIF-2B follow-up report is used to provide additional information about the injured worker’s medical care, and must be completed within 28 days of the incident. The report includes information about the injured worker’s medical treatment, including doctor or hospital visits, medications, and other services. The report also includes information about the employer’s compliance with safety regulations or other requirements.
