Serious Injury and Fatality, the ASTM activity for 2026–2027 is a major shift from traditional injury-counting toward SIF classification, pSIF identification, SIF risk prioritization, safeguard verification, and leadership/worker engagement.

Bottom line

Three SIF-related ASTM standards are already active in 2026, and one related engagement standard remains the principal 2026–2027 watch item.

1. ASTM E2920-26 — revised injury/illness and SIF recording standard

ASTM E2920-26 is active as of January 26, 2026. It revises the prior injury/illness recording guide to expressly address SIF-related serious injuries, illnesses, and fatalities. The important change is that it now classifies incidents into benchmarkable Level One and Level Two incidents, nonmandatory lower-level incidents, potential SIFs (pSIFs), and SIFRisk conditions.

The legal/practical significance is that employers using ASTM E2920-26 will be expected to look beyond OSHA-recordable rates and ask whether an event had life-ending, life-threatening, or life-altering potential, even where the actual injury was minor or avoided by safeguards.

2. ASTM E3519-26 — new standard for non-injury SIF events

ASTM E3519-26 is active as of May 27, 2026. It covers serious incident and fatality events other than employee work-related injuries and illnesses, including serious fires, environmental impacts, operational disruptions, and similar high-consequence events.

This is a significant expansion of SIF thinking. It means an organization’s SIF program should not stop at employee injuries. Serious fires, chemical releases, business interruption, community impacts, and major asset-damage events may now be classified and benchmarked as SIF-related events if they meet the standard’s criteria.

3. ASTM E3529-26 — new SIF risk identification and reduction standard

ASTM E3529-26 is active as of June 3, 2026. It provides a systematic approach to identify, prioritize, reduce, and control workplace risks specific to serious incidents and fatalities, including hazard identification, risk assessment, safeguards, performance monitoring, and leadership review.

This is the most operationally important of the new standards. It moves SIF management from “record what happened” to “identify where catastrophic potential exists, verify safeguards, and reduce risk before the event occurs.” ASTM states that the guide is intended to align with safety management system principles such as ISO 45001.

4. ASTM WK92350 — worker and executive engagement standard still in development

ASTM WK92350 remains a work item for a new guide on evaluating worker and executive engagement in occupational safety and health management. Its scope includes involvement from frontline workers through executives, with keywords including employee engagement, worker involvement, and safety culture.

This appears to be the key 2026–2027 pending item. ASTM’s E34.80 subcommittee lists WK92350 along with the SIF risk and non-injury SIF work items, and ASTM’s May 2026 update identifies related proposed standards on assessing SIF risks and engaging leaders and teams in SIF prevention.

What this means for IHMM / EHS programs

The ASTM SIF package is moving the profession toward a more defensible SIF prevention framework built around:

  1. standardized SIF and pSIF classification;
  2. recognition of non-injury catastrophic events;
  3. risk prioritization based on severity, likelihood, energy, and safeguard reliability;
  4. documented safeguard verification;
  5. leadership and worker engagement as part of SIF prevention.

These are voluntary consensus standards, not OSHA regulations by themselves, unless adopted by contract, policy, procurement requirement, regulation, or litigation standard-of-care arguments. ASTM describes itself as a developer of voluntary consensus standards, and ASTM standards can become mandatory when incorporated into laws, regulations, codes, contracts, or procurement requirements.

For 2026–2027, we should treat ASTM’s SIF standards as a new benchmark for modern safety management systems and begin aligning incident reporting, near-miss review, root cause analysis, serious event classification, and executive safety dashboards to E2920-26, E3519-26, and E3529-26, while monitoring WK92350 for final publication.

Overall meaning for IHMM credentials

The standards should be treated as an emerging standard-of-care development. ASTM standards are voluntary consensus standards, but ASTM itself notes that agencies often use such standards for regulatory or procurement purposes. For IHMM, that means SIF should become part of the credential ecosystem through:

  1. blueprint review;
  2. study guide updates;
  3. CMP/professional development courses;
  4. exam-item review where job-task analysis supports it;
  5. employer-facing messaging showing that IHMM certificants understand modern SIF prevention.

This does not mean IHMM must immediately rewrite every exam. It means IHMM should document that SIF is now a material competency area and then determine, through SMEs and blueprint review, where it belongs.

CHMM®

For the CHMM, the ASTM SIF changes strengthen the credential’s relevance to high-consequence hazardous materials work. IHMM describes the CHMM as a professional able to identify and assess hazardous materials risks, mitigate or eliminate those risks, and manage impacts to human health and the environment.

The SIF connection is direct: hazardous materials incidents often involve the exact conditions ASTM is now emphasizing—fires, releases, explosions, acute toxic exposures, environmental releases, and business-disrupting events. E3519-26 is especially important because it addresses serious non-injury events, including environmental protection and operational stability concerns.

Credential implication: CHMM materials should include SIF/pSIF classification, catastrophic potential, safeguard verification, release scenarios, emergency response linkage, and root-cause analysis for high-consequence hazmat events.

CHMP®

For the CHMP, SIF is a practical field-competency issue. IHMM materials describe the CHMP as focused on technical knowledge and expertise in handling hazardous materials and applying controls through the hazardous materials life cycle, including handling, transportation, storage, recycling, and disposal.

The ASTM changes give CHMPs a stronger framework for recognizing when a near miss is not “minor” but a potential SIF. A dropped cylinder, incompatible chemical storage, forklift impact to hazmat containers, or failed secondary containment may now require SIF-level attention even if no one was hurt.

Credential implication: CHMP training should emphasize frontline recognition of pSIFs, escalation protocols, control verification, incident preservation, and reporting serious potential events before they become fatalities or major releases.

CSHM®

The CSHM is the credential most directly affected. IHMM describes the CSHM as recognizing knowledge of occupational safety and health, business and financial principles, hazard analysis, accident investigation, safety audits, workers’ compensation, product safety, environmental laws, labor relations, and related management subjects.

ASTM E2920-26 is expressly aimed at improving management systems, measuring safety performance, identifying and preventing serious injuries/illnesses/fatalities, and supporting comparison and benchmarking. That is squarely within the CSHM’s management role.

Credential implication: CSHM should become IHMM’s lead credential for SIF prevention leadership. The blueprint and study guide should address SIF governance, executive dashboards, leading indicators, pSIF review, incident classification, serious-risk registers, safeguard effectiveness, contractor accountability, and management review.

CSMP®

For the CSMP, the significance is operational. IHMM describes CSMP as recognizing workplace safety and health professionals who may have less formal education but can demonstrate mastery of workplace safety and labor-law regulations through training and experience.

The CSMP population is often closest to the work. ASTM SIF concepts give those professionals a disciplined way to identify high-energy hazards, weak controls, and near misses with fatal potential.

Credential implication: CSMP materials should focus on practical implementation: job hazard analysis, pre-task planning, field observations, stop-work authority, pSIF reporting, corrective action tracking, and verifying whether controls actually work in the field.

CSSM®

For the CSSM, SIF should be adapted to the school environment. IHMM describes the Certified School Safety Manager as responsible for overseeing and supporting key operational and safety functions in educational facilities, with focus on the security and safety of the institution and everyone who works and studies there.

In schools, SIF thinking applies to severe but preventable events: laboratory chemical incidents, shop/classroom machinery, transportation, athletics, slips/falls from height, violence prevention, emergency response failures, fires, and facility hazards.

Credential implication: CSSM should incorporate SIF concepts into school hazard assessments, emergency action planning, facilities inspections, incident review, threat/risk prioritization, and leadership reporting.

IHMM action plan

IHMM should treat ASTM SIF as a cross-credential enhancement, not as a standalone credential requirement. I would recommend:

  1. create a short IHMM Foundation course: “ASTM SIF Standards and Serious Risk Prevention for IHMM Certificants”;
  2. add SIF/pSIF learning objectives to CHMM, CHMP, CSHM, CSMP, and CSSM professional development;
  3. ask each credential’s SMEs whether SIF belongs in the next JTA/blueprint revision;
  4. prepare employer-facing language explaining that IHMM certificants are trained to recognize serious-risk potential, not merely record injuries after harm occurs.

The strongest legal point is this: ASTM SIF moves professional competence from lagging injury rates to foreseeable serious-risk prevention. That is exactly where IHMM credentials should be positioned.
