What is ISO 14119:2014?

Introduction

In the world of industrial automation and machinery, safety is of paramount importance. ISO 14119:2014 is a standard that addresses the topic of interlocking devices associated with guards. It provides guidelines for the design, selection, and application of these devices to ensure the safety of personnel working in proximity to hazardous equipment.

The Purpose of ISO 14119:2014

ISO 14119:2014 sets out to establish uniform requirements for the various types of interlocking devices used with guards. These devices are intended to prevent access to hazardous areas while machinery is in operation. The standard outlines five basic principles that should be followed when designing and implementing interlocking devices:

A device shall operate to achieve the desired control function

The control circuitry shall be resistant to defeat

It shall not be possible to initiate a restart of the hazardous process without releasing the device

If the device fails, a failure mode resulting in a state favouring safety shall be provided

The control system shall include self-checking features

Implementing ISO 14119:2014

To adhere to the ISO 14119:2014 standard, manufacturers of industrial machinery must ensure that their interlocking devices comply with the requirements outlined in the document. This involves performing a risk assessment to identify the hazards associated with their equipment and selecting interlocking devices that provide the necessary level of protection.

Additionally, proper installation and maintenance of interlocking devices are crucial. Regular inspections should be conducted to ensure that these devices are operating correctly and have not been tampered with or bypassed in any way.

The Benefits of ISO 14119:2014

By following the guidelines set forth in ISO 14119:2014, organizations can achieve a higher level of safety for their personnel. Interlocking devices that comply with this standard help mitigate risks associated with machinery and prevent unauthorized access to hazardous areas.

Furthermore, adherence to international standards can enhance an organization's reputation and provide reassurance to customers, suppliers, and regulatory bodies that safety is a top priority.

In conclusion, ISO 14119:2014 plays a critical role in ensuring the safety of workers in industrial environments. By setting clear guidelines for interlocking devices associated with guards, this standard helps organizations mitigate risks and prevent accidents. Adhering to ISO 14119:2014 not only protects personnel but also enhances an organization's overall safety culture.
