Safety of Machinery—Principles for Risk

For example, the hazard analysis and risk assessment requirements of the European Standard ISO 14121, Safety of Machinery—Principles for risk assessment (formerly EN 1050), have been adequately met in some companies in the design or redesign stages by applying an adaptation of the preliminary hazard analysis technique. 

Safety of Machinery—Principles for risk assessment. International Standard ISO 14121 (formerly EN 1050). Geneva, Switzerland International Organization for Standardization, 1999. 

But EN 292 does not include a methodology to identify hazards and assess risks. To clarity the intent of EN 292 and to provide a framework manufacturers could consider, standard EN1050 was developed and published in 1997. Its title is Safety of machinery—Principles for risk assessment. In 1999, EN 1050 was adopted by the International Committee for Standardization as International Standard ISO 14121, without change. ISO 14121 does what it purports to do It sets forth a hazard identification and risk assessment methodology. 

For example, a European standard adopted by the International Organization for Standardization (ISO) requires that risk assessments be made for all machinery to go into a workplace within the European Community. That standard is ISO 12100-1, Safety of Machinery—Basic Concepts, General Principles for Design Part 1, Basic Terminology, Methodology. The risk assessment process is outlined in ISO 14121, Safety of Machinery—Principles for Risk Assessments. These risk assessment requirements have been met in some companies by applying an adaptation of the PHA technique. 

For example, it has been used with minor modification by at least one U.S. company to meet the European Community risk assessment requirements as set forth in ISO 14121, the Safety of Machinery—Principles for Risk Assessment Standard. As will be illustrated later, this risk-scoring system has major shortcomings.

The checklist in Addendum B at the conclusion of Chapter 8 is adapted from ISO 14121, the Safety of Machinery—Principles of Risk Assessment Standard. It is to serve as a guide for those who design and manufacture equipment and machinery that goes into European workplaces.

This checklist is an adaptation of information that appears in the ISO s Safety of Maehinery—Principles of Risk Assessment, Standard, IS014121. The checklist is a guide for companies located throughout the world who design and manufacture machinery and equipment that would go into European workplaces. Although the checklist pertains to a broad range of equipment, those who use it as a reference must understand that it could not possibly include all hazards and all hazardous situations. 

EN ISO 12100-2010. Safety of Machinery. General Principles for Design. Risk Assessment and Risk Reduction.This standard combines three previously issued ISO standards (including item 8 in this hsting) and replaces them. Risk assessments are explicitly required. 

Emergency stopping facilities must be provided where they will contribute to risk reduction. Therefore, they are not needed where they will not lessen the risk of injury or in hand-held portable and hand-guided machines. The particular requirements for the equipment are laid out in BS EN 418 Safety of machinery - Emergency stop equipment, functional aspects - Principles for design.

Description The standard establishes general principles for risk assessment, and gives guidance on the information required to allow risk assessment to be carried out. The purpose of the standard is to provide advice for decisions to be made on the safety of machinery. 

Basic standards (type A). These fundamental standards contain general principles for safe design or measurement techniques/levels for EMC and may be applied to products when appropriate. The A and B standards are especially important for EMC and machinery. Some examples of basic safety standards for machinery are EN 292-1/-2 (Design Concepts), and EN 1050 (Risk Assessment). The EN 61000-4-X series (lEC 801-X) for immunity levels is an example of basic standards for EMC.
