What is EN ISO 12100:5-2021?

EN ISO 12100:5-2021 is a technical standard that addresses the safety requirements for machinery. It is part of the ISO 12100 series that provides guidelines for the design, risk assessment, and risk reduction processes of machinery. This article aims to provide a thorough understanding of EN ISO 12100:5-2021 and its significance in ensuring the safety of machinery.

The Scope of EN ISO 12100:5-2021

The scope of EN ISO 12100:5-2021 encompasses the identification of hazards and the estimation of risks associated with machinery. It applies to all activities and phases of the machine lifecycle, from concept development to disposal. The standard establishes principles for risk assessment and risk reduction to protect both machine operators and maintenance personnel against potential risks.

Risk Assessment and Hazards Identification

In accordance with EN ISO 12100:5-2021, risk assessment is an integral part of the machine design process. It involves identifying and evaluating potential hazards to determine their likelihood and consequences. Hazards may include mechanical, electrical, thermal, or chemical risks that can cause harm to individuals interacting with the machinery.

To identify hazards, a comprehensive analysis of the machinery's components, functions, and operating conditions is conducted. This analysis helps to define protective measures necessary to reduce risks to an acceptable level. The information obtained during hazard identification serves as a basis for further risk reduction measures.

Risk Reduction Measures and Safety Requirements

EN ISO 12100:5-2021 outlines various risk reduction measures required to minimize identified hazards. These measures include both inherent design characteristics and safeguarding techniques implemented during the construction of the machinery.

Designers and manufacturers should follow specific safety requirements specified in the standard, such as ensuring appropriate access to controls, avoiding sharp edges or protrusions, providing clear warning signs, and implementing emergency stop devices. Additionally, the standard emphasizes the importance of providing proper instructions for use, maintenance, and dismantling of machinery.
