Overview of Standards

US Standards • OSHA - The law “ have to comply” • States must meet or exceed • OSHA Regulations defined in C ode of F ederal R egulations Title 29 • Reference to Standards such as ANSI and NFPA • ANSI – Coordinates Voluntary Standards • ANSI – Official representative to ISO/IEC • TUV – OSHA recognized NRTL

OSHA Standards on LOTO Part 1910: Occupational Safety and Health Standards Subpart O: Machinery and Machine Guarding 1910.147(a)(2)(ii) The minor servicing exception 1910.211: Definitions provides that minor tool changes and adjustments and other minor servicing activities which take 1910.212: General Requirements for place during normal production all Machinery operations may be exempt from the LOTO standard if the activity is 1910.213-190.219: Machine Specific routine, repetitive, and integral to Regulations the use of the equipment for production purposes, provided that the work is performed using Subpart J: General Environment Controls alternative measures which provide effective employee 1910.147: The Control of Hazardous protection.

European Standards • Goal to achieve free movement of goods and protecting its citizens • EU-Directives define: • Basic product Requirements • Basic requirements for safe Machinery Work operation Directive Equipment • Minimum requirements for safety 2006/42/EC 2009/104/EC at work • Technology neutral • Standards Not Mandatory – is a legal obligation to keep to the EU-Directives • “Declaration of Conformity”

Global Convergence Global Machine Safety Standard Convergence

Three-tier Safety Standards Structure EXAMPLES: Type A ISO 12100 Safety of machinery. Basic terminology and methodology ISO 14121 Safety of machinery. Risk assessment Type B ISO 13849-1 - Safety related parts of control systems ISO 13850 - Emergency stop function IEC 62061 - Functional safety of electrical control systems IEC 60204-1 - Safety of machinery. Electrical Fundamental safety standards applicable to all Equipment Type A machine. Type A standards deal with basic concepts, principles for design, and general ANSI/NFPA 79 – Electrical standard for Industrial aspects. Machinery Standard applicable to a wide range of machinery. Type C Type B is divided into two categories: EN 12012 – Safety requirements - Plastics and Rubber Type B B1: Specific safety aspects (i.e., safety distance, machines surface temperature, and noise.) B2: Safety related devices (i.e., two-hand controls, ISO 10218 - Safety requirements – Industrial Robots interlocking devices, pressure sensitive devices and guards) ANSI/B155.1 - Safety Requirements for Packaging Machinery and packaging-Related Converting Type C Detailed standards applicable to a specific machine Machinery or a particular group of machines Source: Rockwell Automation

Standard EN/IEC 62061 • Specific to the machine sector within the framework of EN/IEC 61508:  gives rules for the integration of safety-related electrical , electronic and electronic programmable control systems (SRECS)  does not specify the operating requirements of non-electrical control components in machine (ex.: hydraulic, pneumatic) • The probability of failure associated to the required SIL (Safety Integrity Level) depends on the frequency of usage of the safety function to be performed Safety of Machinery application EN/IEC 62061

Standard EN/ISO 13849-1 • The Standard gives safety requirements for the design and integration of safety-related parts of control systems, including software design. • The Risk Graph helps to determine the required PLr (Performance Level Required) of each safety function

Risk Assessment Risk Define Design Implement Validate Assessment • Importance of performing a Risk Assessment  Risk Assessment is referenced throughout US safety standards • ANSI Z244.1 • ANSI B11.19 • ANSI/RIA R15.06 • NFPA 79  Note that ANSI/RIA 15.06 requires a risk assessment starting January 2015.  Risk Assessment in the EU is a requirement to obtaining a CE label

Risk Assessment Identification of Hazards

Risk Assessment Risk Estimation

Risk Assessment Risk Reduction Protective Measures Examples • Design It Out Eliminate the Risk • Process Substitution Most Effective • Fencing or Barriers Physical Guarding • Fixed Covers • Interlocks, Light Curtains, Safety Mats Engineering Controls • Monitoring Relays, Safety PLCs (Safeguarding Technology) • Signs, Warnings, Annunciation Lights Awareness Means • Safety Glasses, Gloves & Footwear (Personal Protective Equipment) Least • Work Procedures Training & Procedures Effective • Lockout / Tagout (LOTO) (Administrative Controls)

Addressing Residual Risk • After safeguarding measures, the standard ISO 12100:2010 refers to complementary measures to further reduce the residual risks to an acceptable level through such measures as training, signage and warning equipment (i.e. Beacons). Residual Risk : “Risk that remains after the protective measures have been implemented.”

Risk Assessment Risk Define Design Implement Validate Assessment • RISK Assessment Exercise  WHO – is involved  WHAT – is the machine’s function  HOW – can someone get injured  WHAT – Type of injury can occur  What – is the risk of the injury  HOW – to protect against the injury  IS – the risk reduction acceptable for the hazard
