What is EN ISO 13850:2021?

EN ISO 13850:2021 is a technical standard that addresses the safety of machinery and equipment by providing guidelines for the design and implementation of emergency stop systems. This standard, published by the International Organization for Standardization (ISO), aims to ensure that emergency stop devices are effective in minimizing risks to operators and others in the vicinity of machinery.

Understanding Emergency Stop Systems

Emergency stop systems are crucial safety features in machinery and equipment. They provide an easily accessible means for operators to quickly halt machine operations in emergency situations. The purpose of these systems is to prevent or mitigate potential harm to personnel, safeguarding their well-being and protecting them from accidents caused by malfunctioning machinery.

In order to comply with EN ISO 13850:2021, emergency stop systems must be designed and implemented correctly. This includes considering various factors such as operational requirements, potential hazards, and the characteristics of the machinery involved. The standard outlines specific requirements for the functionality, reliability, and placement of emergency stop devices.

Key Requirements of EN ISO 13850:2021

EN ISO 13850:2021 outlines several key requirements for emergency stop systems. One important aspect is the need for emergency stop devices to be easily recognizable and distinguishable from other controls. They should have a distinctive design or color, making them readily identifiable to operators, even in stressful situations.

The standard also emphasizes the importance of emergency stop systems being fail-safe. This means that activating the emergency stop device should immediately initiate a safe stop of the machinery. Furthermore, it requires that once the emergency stop system has been activated, a manual reset is necessary before resuming normal operations.

Implementing EN ISO 13850:2021

Implementing the requirements of EN ISO 13850:2021 involves a systematic approach to ensure the safety of machinery and equipment. It is important to conduct a thorough risk assessment, identifying potential hazards and determining the appropriate emergency stop measures based on their severity.

Additionally, organizations should provide proper training for operators on the correct use of emergency stop systems. This includes familiarizing them with the location, function, and operation of these devices, as well as explaining the importance of promptly activating them in emergencies.
