What is BS EN ISO 13850:2013?

In this article, we will explore the technical standards and specifications outlined in BS EN ISO 13850:2013. This standard, titled "Safety of machinery - Emergency stop - Principles for design," provides guidelines for the design and implementation of emergency stop systems for various machinery.

Key Components of BS EN ISO 13850:2013

The standard emphasizes several key components that are essential for an effective emergency stop system. First and foremost, it highlights the importance of a clearly identifiable emergency stop control device, which should be in close proximity to the operator and easily accessible in case of an emergency.

An emergency stop control device is typically designed as a large, red mushroom-shaped button. Its purpose is to ensure immediate and safe shutdown of machinery or equipment when a hazardous situation occurs or when human intervention is necessary.

Principles for Designing an Effective Emergency Stop System

BS EN ISO 13850:2013 also outlines a series of principles that should be followed when designing an emergency stop system. These include:

Stop Category: Machinery should be classified into one of three stop categories, depending on the level of risk associated with it. This classification determines the performance levels required for the emergency stop system.

Stop Functionality: When activated, the emergency stop system must ensure the immediate cessation of all hazardous movements. The system should override other control functions and prevent accidental reactivation.

Resetting and Restarting: After the emergency stop has been activated, it's crucial to have a defined procedure for resetting and restarting the machinery. This should involve a deliberate action from the operator to ensure safe resumption of operation.

Benefits and Importance of BS EN ISO 13850:2013 Compliance

Complying with BS EN ISO 13850:2013 brings several benefits for both machinery manufacturers and operators. By implementing this standard, manufacturers can enhance the safety features of their machinery, reducing the risk of accidents and injuries in the workplace.

For operators, having an emergency stop system that adheres to these guidelines provides peace of mind and a sense of control. In case of any emergencies or unexpected situations, they can quickly and easily halt the machinery, potentially saving lives and preventing further damage.

In conclusion, BS EN ISO 13850:2013 plays a crucial role in ensuring the safety of machinery by providing clear and concise guidelines for designing and implementing effective emergency stop systems. By following these standards, manufacturers and operators can create a safer working environment and prevent accidents that can have severe consequences.
