ANSI B11.0-2023 Task-Based Machinery Risk Assessment Form
ANSI B11.0-2023 requires machinery suppliers and users to conduct task-based risk assessments covering all lifecycle phases before placing machinery in service. Non-compliance directly implicates the OSHA General Duty Clause (29 USC 654(a)(1)), exposing employers to willful citations up to $165,514 per violation.
- Industry: Manufacturing
- Frequency: Before each new machine is placed in service; revalidated every 5 years or following any significant change to the machine, its use, or its environment
- Estimated Time: 45-90 minutes
- Role: Safety Engineer
- Total Items: 20
- Compliance: ANSI B11.0-2023 Clause 5.2 (Limits of the Machinery), ANSI B11.0-2023 Clause 6.4 (Risk Estimation and Evaluation), ANSI B11.0-2023 Clause 8 (Hierarchy of Risk Reduction), ANSI B11.0-2023 Clause 9 (Verification and Validation), OSHA General Duty Clause 29 USC 654(a)(1)
Step 1: Set the Limits and Scope (ANSI B11.0-2023 Clause 5.2)
Establish the boundaries of the machinery before any hazard identification begins. Defines intended use, reasonably foreseeable misuse, all lifecycle phases, and the operating environment.
- Is the intended use and reasonably foreseeable misuse of the machinery documented in the assessment scope?
- Are all lifecycle phases covered in the scope: installation, setup, normal operation, maintenance, cleaning, troubleshooting, and decommissioning?
- Is a qualified, cross-functional assessment team assembled, including operator and maintenance representation?
- Attach photo of the assessment scope and limits documentation:
Hazard Identification and Risk Register (ANSI B11.0-2023 Clause 6)
Identify all task-hazard pairs across every lifecycle phase. Apply the Clause 6.4 severity and probability scales consistently to each pair.
- Have all task-hazard pairs been identified across every lifecycle phase listed in the scope?
- Is the Clause 6.4 severity/probability risk matrix applied consistently using the documented criteria for every task-hazard pair?
- Total number of task-hazard pairs in the risk register:
- Attach photo of the completed task-hazard risk register:
Three-State Risk Scoring: Initial, Existing, and Residual
Score each task-hazard pair at three states per ANSI B11.0-2023 Clause 6.4. This three-state structure is what OSHA compliance officers and insurance auditors look for.
- Is each task-hazard pair scored at all three states: initial (no safeguarding), existing (current controls in place), and residual (after planned measures are validated)?
- Do all residual risk levels meet the organization's defined acceptable risk threshold?
- Number of task-hazard pairs with residual risk still above the acceptable threshold (requiring further action):
- Attach photo of residual risk scoring and open action items:
Hierarchy of Risk Reduction and Verification (Clauses 8 and 9)
Confirm risk reduction measures follow the Clause 8 hierarchy in correct order. Verify and validate each implemented measure per Clause 9.
- Are risk reduction measures applied in the correct Clause 8 hierarchy: (1) elimination/substitution, (2) engineering controls, (3) awareness means, (4) administrative controls, (5) PPE?
- Has each implemented risk reduction measure been verified and validated to confirm it performs as intended and does not introduce new hazards?
- Attach photo of verification and validation records for implemented risk reduction measures:
- Assessment facilitator sign-off (confirming assessment methodology, team composition, and V&V records are complete):
Corrective Actions and Sign-Off
Document any task-hazard pairs with residual risk above the acceptable threshold and the assigned corrective actions.

Frequently Asked Questions
What should an ANSI B11.0-2023 task-based machinery risk assessment form include?
An ANSI B11.0-2023 compliant risk assessment form must cover seven elements. First, Step 1 limit-setting: documented intended use, reasonably foreseeable misuse, all lifecycle phases (installation through decommissioning), physical boundaries, and operating environment per Clause 5.2. Second, a qualified cross-functional assessment team with operator and maintenance representation per Clause 5 responsibilities. Third, systematic hazard identification across all lifecycle phases per Clause 6.2. Fourth, a documented severity-probability risk matrix applied consistently to every task-hazard pair per Clause 6.4. Fifth, three-state scoring for each pair: initial, existing, and residual risk. Sixth, risk reduction measures applied in the Clause 8 hierarchy order. Seventh, verification and validation records per Clause 9 confirming each measure performs as intended without introducing new hazards.
How often must ANSI B11.0-2023 machinery risk assessments be conducted?
ANSI B11.0-2023 Clause 4 requires a risk assessment before each new machine is placed in service. Revalidation is required every five years, or sooner when a significant change is made to the machine, its operating environment, its use, or when a new hazard is identified. ANSI B11.0-2023 also requires reassessment immediately following any serious incident or near-miss involving the machinery. When modifying an existing machine, the assessment must cover the changed elements and any new hazards introduced by the modification. OSHA enforcement practice treats failure to revalidate following a significant change as equivalent to having no assessment, since the original document no longer reflects the current machine state.
What is the three-state risk scoring method in ANSI B11.0-2023?
ANSI B11.0-2023 Clause 6.4 requires each task-hazard pair to be scored at three distinct states. The initial state scores the risk with no safeguarding in place, establishing the baseline hazard level. The existing state scores the risk with current safeguarding already installed, showing what current controls actually achieve. The residual state scores the risk after all planned additional risk reduction measures have been implemented and validated, confirming the final risk level. Each state uses the same documented severity and probability criteria. The three-state structure is specifically what OSHA compliance officers and insurance auditors look for because it proves the assessment team understood the hazard before safeguarding was applied, not just after - preventing the common deficiency of reverse-engineering an assessment around existing controls.
Who is qualified to conduct an ANSI B11.0-2023 machinery risk assessment?
ANSI B11.0-2023 Clause 5 defines responsibilities for both the supplier and the user. The assessment facilitator must have knowledge of risk assessment methodology, the applicable B11 type-C standards for the machine type, and relevant regulatory requirements. The team must be cross-functional and include operator representatives with hands-on machine knowledge, maintenance personnel familiar with the machine systems, engineering or controls expertise, and EHS representation. For complex machinery, certified Functional Safety Engineers (TUV or equivalent) are often needed to determine performance levels for control-based safeguards per ANSI B11.26 or ISO 13849-1. The standard does not prescribe a specific certification but requires that team members be competent for their assigned role in the assessment.
What is the difference between ANSI B11.0-2023 and ANSI B11.0-2015?
ANSI B11.0-2023 introduced several substantive changes from the 2015 edition. The 2023 edition added machinery systems requirements, addressing situations where multiple machines or control systems interact as a system rather than standalone units. The information-for-use requirements were updated with new Clause 7.17 guidance and Annex M on residual risk communication, making documentation of residual risks to users more specific. The 2023 edition also aligned more closely with ISO 12100 methodology and updated cross-references to the revised ANSI B11 type-C standards. Assessments conducted to the 2015 edition are not automatically non-compliant, but OSHA enforcement and third-party auditors increasingly expect the 2023 methodology, particularly the updated information-for-use documentation and the machinery systems provisions, for assessments initiated after the 2023 edition was published.
What happens if a machinery risk assessment is missing or incomplete under ANSI B11.0-2023?
A missing or incomplete ANSI B11.0-2023 risk assessment creates two categories of liability. First, OSHA enforcement: ANSI B11.0 is a RAGAGEP standard incorporated by reference under the General Duty Clause (29 USC 654(a)(1)). Following a serious machinery incident, OSHA investigators examine risk assessment documentation as one of the first steps. Absent documentation, incomplete lifecycle phase coverage, or use of an outdated edition has resulted in willful citations up to $165,514 per violation, compounded by machine-specific B11 type-C standard citations. Second, civil liability: in machinery injury litigation, plaintiff attorneys routinely subpoena risk assessment records. An absent or inadequate assessment becomes direct evidence of negligence, often removing the employer's ability to assert a regulatory compliance defense. Insurance carriers are also increasingly requiring documented ANSI B11.0 assessments for machinery risk coverage.
