The Colorado WC 1 form, officially known as the Employer’s First Report of Injury, serves as a critical document in the workers' compensation process. This form must be completed by employers when an employee sustains a work-related injury or illness, ensuring that all necessary details are accurately reported. Key information required includes the employee's personal details, such as name, address, and social security number, as well as specifics about the injury, including the date it occurred, the nature of the injury, and the circumstances surrounding the incident. Employers must also provide information about the average weekly wage of the injured employee, which can include additional benefits like tips and health insurance. The form further requires details about the employer, including their name and federal ID number, and whether they are self-insured. It is crucial to note that all injuries, regardless of severity, must be reported within a specific timeframe, especially those resulting in lost time from work or permanent impairment. By adhering to these guidelines, employers can ensure compliance with Colorado's workers' compensation laws while facilitating timely support for injured employees.
