The Illinois First Report 45 form is a crucial document that employers must complete when a work-related injury occurs. Designed to capture essential information, this form helps ensure that both employees and employers navigate the complexities of workers' compensation effectively. Key details required include the employer's information, such as the Federal Employer Identification Number (FEIN), business name, and mailing address. It also asks for specifics about the injured employee, including their name, birthdate, and job title. Understanding whether the incident resulted in lost workdays is vital, as this can influence the reporting process. The form delves into the circumstances surrounding the accident, requesting descriptions of what the employee was doing at the time, how the injury occurred, and the nature of the injury itself. Additional inquiries cover medical treatment received, including whether the employee was treated in an emergency room or hospitalized. By gathering this information, the form serves not only as a report to the Illinois Workers' Compensation Commission but also as a means for employers to maintain compliance with legal requirements. Remember, filing this form is a step toward protecting both the rights of the injured employee and the interests of the employer.
