The Maine Employers First Report of Occupational Injury or Disease is a document that employers in the state of Maine must complete in order to comply with the state's Occupational Injury and Illness Recording and Reporting (OI IRR) regulations. The report must be filed within three working days of the employer becoming aware of a work-related injury or illness. The report must contain information such as the date of the incident, the location, the type of injury or illness, the affected employee's name and contact information, the name and contact information of the employer, and a description of the event. The report is used to collect data on workplace injuries and illnesses, which is used to create safety programs to reduce the risk of similar incidents in the future. There are two types of Maine Employers First Report of Occupational Injury or Disease: Form OIIRR-1, which is used for non-fatal injuries or illnesses, and Form OIIRR-2, which is used for fatal injuries or illnesses.
