FAQ

ANSI B11.0 — Safety of Machinery

The ANSI B11.0 standard (Safety of Machinery) is the foundational “Type A” standard of the B11 series of American National Standards for machine safety.
It is intended to apply broadly to power-driven machines (new, existing, modified or rebuilt) and to machinery systems, not portable tools held in the hand. :contentReference[oaicite:0]{index=0}
ANSI B11.0 provides the essential framework: definitions, lifecycle responsibilities, risk assessment methodology, acceptable risk criteria, and guidance for using Type-C standards in conjunction with this general standard. :contentReference[oaicite:1]{index=1}

Scope & Purpose

ANSI B11.0-2020 covers machines and machinery systems used for material processing, moving or treating when at least one component moves and is actuated, controlled and powered. :contentReference[oaicite:2]{index=2}
The standard’s purpose is to help suppliers, integrators, and users of machinery identify hazards, estimate and evaluate risks, and implement sufficient risk reduction to achieve an “acceptable risk” level. :contentReference[oaicite:3]{index=3}
It also clarifies responsibilities across the machine lifecycle (supplier, user, modifier) and addresses legacy equipment, prevention through design (PtD) and use of alternative methods for energy control. :contentReference[oaicite:4]{index=4}

Key Concepts & Requirements

• Terminology & Definitions: Establishes key machine-safety terms (e.g., machine, hazard zone, safeguarding, risk, risk reduction). :contentReference[oaicite:5]{index=5}
• Risk Assessment Methodology: Describes how to identify hazards, estimate risk severity and probability, evaluate risk, and decide on corrective safeguards. :contentReference[oaicite:6]{index=6}
