What is EN ISO 12100:2021?

EN ISO 12100:2021 is a comprehensive standard that provides guidelines and requirements for machinery safety. It aims to ensure the safety of operators, maintenance personnel, and other individuals who interact with machinery during its entire lifecycle.

This technical article will delve into the key aspects of EN ISO 12100:2021, including its scope, principles, and risk assessment methods.

Scope of EN ISO 12100:2021

EN ISO 12100:2021 applies to all types of machinery, regardless of its complexity or application. It covers various stages of the machinery lifecycle, from design and construction to operation, maintenance, and decommissioning.

The standard focuses on providing guidance for eliminating or minimizing risks associated with machinery. It encompasses potential hazards such as mechanical, electrical, thermal, and noise-related dangers. By following the requirements outlined in EN ISO 12100:2021, manufacturers can ensure that their machinery meets the necessary safety criteria.

Principles of EN ISO 12100:2021

EN ISO 12100:2021 is based on several fundamental safety principles. These principles serve as a basis for assessing and reducing risks associated with machinery:

1. Hazard Identification: The standard emphasizes the importance of identifying and understanding potential hazards associated with machinery. This includes considering both the intended use and foreseeable misuse of the machinery.

2. Risk Assessment: EN ISO 12100:2021 promotes a systematic approach to risk assessment. It guides manufacturers to identify, analyze, and evaluate risks during all stages of machinery implementation.

3. Risk Reduction: The standard highlights the need to reduce risks by implementing appropriate protective measures. This involves applying safety measures at the design level, such as enclosure of hazardous areas or installation of safety interlocks.

Risk Assessment Methods

EN ISO 12100:2021 introduces two primary risk assessment methods:

1. Qualitative Risk Assessment: This method involves evaluating risks based on their severity, probability, and detectability. It utilizes qualitative scales to assess each aspect and helps prioritize risk reduction measures.

2. Quantitative Risk Assessment: In addition to qualitative evaluation, this method involves numerical analysis. It assigns values to risks and determines whether they meet acceptable levels defined by relevant standards and regulations.

Both methods aim to provide a structured approach towards risk assessment, enabling manufacturers to make informed decisions regarding safety measures implementation.
