7 ISO 4413 is a Type B Standard in the Machinery Safety Standards Hierarchy Type A standards (basic safety) Basic concepts and principles applicable to all machinery Type B standards (generic safety standards) One safety aspect or type of safeguard applicable to a wide range of machinery Type C standards (machine safety standards) Detailed requirements for a particular machine or group of machines When a type C standard deviates from one or more provisions of a type B standard, the type C standard takes precedence. (See ISO for complete definitions)

11 Actions to Address Identified Risks Follow ISO hierarchy 1. Inherently safe design measures (Eliminate risks by design where possible) 2. Safeguarding and complementary protective measures 3. Information for use from the supplier Warning signs, signals, or devices at the machine Warnings in the instruction manual 4. Protective measures taken by the user Procedures, supervision, permit to work systems Additional safeguards Training, use of PPE
