    Serious Injury or FatalitySIF

    Also known as: Serious incident and fatality, Potential SIF (pSIF)

    Definition

    Serious Injury or Fatality — a term used to distinguish severe outcomes and, in potential-SIF reviews, events that could have caused them.

    Editorial definition: The QHSE Standard, updated 3 October 2026 · https://qhsetech.com/glossary/sif

    Scope: Define the actual and potential severity criteria before comparing records.

    How the term is used, and how it differs from legal reporting

    SIF has no single legal definition. The National Safety Council (NSC) says it stands for serious incidents and fatalities, which is why the same abbreviation is sometimes expanded as serious injury or fatality. NSC describes potential SIFs, or pSIFs, as near misses or lower-severity incidents that could have resulted in a SIF if one or two factors were different, and says they show where critical safeguards and controls are weak or missing. The distinction matters for records: the label attaches to what could have happened as well as to what did.

    A published recording guide exists. NSC's statement of 2 February 2026 welcomed the updated ASTM E2920-26, titled as a standard guide for recording priority occupational injuries and illnesses and SIF-related serious injuries, illnesses and fatalities. ASTM's summary describes levels of incident, with Level One for actual SIF cases that have life-ending, life-threatening or life-altering consequences, and it covers potential SIFs separately as events with a clear workplace connection and a likelihood of such consequences. It is a guide, not a regulation, and it is a paid document, so read its text before writing it into a procedure.

    Legal reporting is a separate question. OSHA's rule at 29 CFR 1904.39 requires an employer to report a work-related fatality within eight hours, and an in-patient hospitalisation, an amputation or a loss of an eye within 24 hours. A fatality counts if it occurs within 30 days of the incident; the other three count only if they occur within 24 hours of it. That list serves OSHA's purposes and need not match an organisation's own SIF criteria, so a record should carry both an internal classification and a regulatory decision, each with an owner.

    What a SIF record holds in software

    • The actual outcome and the potential outcome as two separate fields, each with the criteria or scale used.
    • A classification step with a recorded reason, so that a decision to rate an event as a potential SIF, or not, can be reviewed later.
    • The control that failed, was absent or worked, named from the organisation's own list of critical controls where one exists.
    • The depth of investigation that followed from the classification, with the people involved and the date it began.
    • A regulatory reporting decision kept apart from the internal classification, with the time limit that applied.

    SIF, recordable injury and lost-time injury

    These are three ways of cutting outcomes that overlap but do not nest neatly. A recordable case is defined by recording rules such as OSHA's and can be minor; a lost-time case depends on days away from work; a SIF is defined by severity or potential severity. A minor recordable injury is not a SIF, and a near miss with no injury at all may be a potential SIF and not recordable. Mixing the labels in one count produces numbers that cannot be compared with anyone else's, so state which definition each number uses.

    A hypothetical example: a pipe slips over an open walkway

    This case is invented and describes no real site. A crew lowers a length of pipe from a platform while a walkway below is open to traffic. The load slips and lands on the walkway, where nobody happens to be. The actual outcome is no injury and minor damage to a handrail. On a records-only view it is a near miss of low consequence.

    The reviewer rates the potential outcome using the site's written criteria, which ask what would have happened if a person had been on the walkway. The answer is a life-threatening injury, and the load was handled with no exclusion zone, so the event is classified as a potential SIF. That classification sends it to a deeper review than its actual result would have earned. The review finds that the exclusion zone was a planning step nobody owned, the actions assign it to the lift plan, and the record names the control that was absent. Some weeks later the same control is checked across other lifts. The event counts in no injury rate; it appears in a separate count of potential SIFs with its own definition.

    Common misunderstandings about SIF

    • Serious is not a matter of feel. Without written criteria, two reviewers rate the same event differently, and the trend then reflects who reviewed rather than what happened.
    • A falling injury rate does not show that serious harm is falling. A rate built on all recordable cases is dominated by minor injuries, and the cases that decide whether someone is killed or disabled are far rarer, so the two measures can move apart.
    • A potential SIF is a judgement, not a measurement. It depends on what the reviewer thinks could have happened, so write down the test (which control failed, what exposure existed) and have a second person check it.
    • SIF is not a legal category. OSHA and other regulators publish their own lists of what must be reported, and an internal SIF label does not replace the reporting decision.
    • Counting SIFs is not preventing them. The value lies in the controls that a review identifies as weak, and in checking those controls before the next event.

    How SIF relates to other glossary terms

    SIF cuts across the usual injury measures, so the closest terms are the rates it is set against and the methods used to understand a serious event.

    • TRIR: the rate for all recordable cases, which does not separate serious outcomes from minor ones.
    • LTIFR: a rate built on lost-time cases, a different cut that also says nothing about the potential of an event.
    • Near miss: the raw material of potential SIFs, once events are classified by what could have happened.
    • Bowtie analysis: a method for mapping the controls between a hazard and a serious outcome, and for showing which one failed.

    Records and evidence that usually exist for SIF

    • Written definitions of serious injury, fatality and potential SIF, with examples and the person or group who applies them.
    • For each event, the actual outcome, the potential outcome and the reasoning behind the rating.
    • The critical controls considered, and which of them failed or were missing.
    • The investigation, its depth, its findings and its actions.
    • Regulatory reporting decisions with their times, kept apart from the internal classification.
    • Verification records showing that the controls named in actions were checked later.

    What a software tool needs to capture for SIF

    • Separate actual and potential severity fields with defined scales and help text, not free text.
    • A classification workflow that records who rated the event, the reason and any second review.
    • Routing that follows potential severity, so that a no-injury event with serious potential reaches the right investigator.
    • Fields to name the control involved and to link to a critical-control list where the organisation keeps one.
    • A regulatory reporting step with its own clock and owner, independent of the SIF label.
    • Reports that count actual SIFs and potential SIFs separately and never fold them into a recordable rate.

    Frequently asked questions

    Is a SIF the same as a recordable injury?

    No. A recordable case is defined by recording rules such as OSHA's and can be minor, while a SIF is defined by severity or potential severity. An event can be one without the other.

    Who decides that an event is a potential SIF?

    The organisation, using written criteria. Judgement is involved, so record the reasoning and check ratings for consistency.

    Does a SIF label change what I must report to a regulator?

    No. Reporting duties come from the law that applies, for example OSHA's 29 CFR 1904.39 in the United States. Treat the internal label and the reporting decision as separate.
