Safety of machinery - General principles for design - Risk assessment and risk reduction

📅 Issue date:2010 🔄 Effective date:2012 🌍 Type:国际标准 / 国家标准 等同采用

📑 Table of Contents

01 Scope

ISO 12100 specifies the general principles for machinery safety design, including risk assessment (analysis and evaluation) and a three-step hierarchy to reduce risk by inherent design, safeguarding and information for use. It is the basis for most machinery safety product standards.

03 Terms and definitions

Risk
Combination of the probability of occurrence of harm and the severity of that harm.
Inherently safe design
Eliminating or reducing risk by design; the first-priority risk-reduction measure.
Safeguarding
Guards and protective devices that physically separate the hazard zone.
Information for use
Warnings and instructions conveying residual risk and correct operation.

04 Technical requirements

Risk reduction (3-step)
  • Step 1: inherently safe design;
  • Step 2: safeguarding and complementary protective measures (e-stop, two-hand control, etc.);
  • Step 3: information for use.
  • Residual risk shall be reduced to ALARA.
Design principles
Stability, strength, guarding, electrical & thermal safety, ergonomics, SRECS per applicable standards.

05 Test methods

Conformity
Verify design and documentation clause-by-clause; confirm by test/analysis that risk is reduced to acceptable level.
