Incidents in Northern Ireland should be reported by contacting the local office of the enforcing authority (usually HSENI) by telephone. They will ask for brief details about your business, the injured person and the accident. You must follow this up with a completed HSENI report form, which can be obtained, from the HSENI website.
You must keep a record of any reportable injury, disease or dangerous occurrence. This record must include the date, time and place of the event, personal details of those involved and a brief description of the nature of the event or disease. You can keep the record in any form you wish.
