Much like the procedure involved in an accident, many places of business require that an incident report be filed when a dangerous, scandalous, or otherwise significantly unusual event takes place. The incident report serves the purpose of documenting all details of the incident for later reference, especially for use in determining liability. Likely, the incident report will include information such as the date of the incident, time, cause, and witnesses. Although not all types of businesses use these incident reports, several use them regularly, including pools, nursing homes, hospitals, schools, and some places of employment. Common examples where an incident report may be necessary include a fire, explosion, unsafe product, patient injury, and harassment.
