    """A safety incident, near-miss, or environmental event.

    The incident register is the central log of anything that did, or
    almost did, harm a worker or the environment. Each record walks
    through draft → investigation → closed and captures who was hurt,
    where, what happened, the immediate response, the investigation
    findings, the root cause and the corrective action.

    For Ontario operations the WSIB Form 7 fields flag whether the
    incident is reportable to the Workplace Safety and Insurance Board
    and whether the form has actually been filed.
