ISO 14118:2017 Compliance Requirements and Safety Guidelines
SN EN ISO 14118:2018
Sicherheit von Maschinen - Vermeidung von unerwartetem Anlauf (ISO 14118:2017)
Safety of machinery - Prevention of unexpected start-up (ISO 14118:2017)
ISO 14118:2017 specifies requirements for designed-in means aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A). ISO 14118:2017 applies to unexpected start-up from all types of energy source, i.e.: - power supply, e.g. electrical, hydraulic, pneumatic; - stored energy due to, e.g. gravity, compressed springs; - external influences, e.g. from wind. ISO 14118:2017 does not specify performance levels or safety integrity levels for safety-related parts of control systems. While available means to prevent unexpected start-up are identified, this document does not specify the means for the prevention of unexpected machine start-up for specific machines. NOTE A type-C standard can define the required means for the prevention of harm arising from unexpected start-up. Otherwise, the requirements for a specific machine need to be determined by risk assessment outside the scope of this document.
The SN EN ISO 14118:2018 standard outlines essential safety requirements aimed at preventing unexpected start-ups of machinery, published by the International Organization for Standardization (ISO). It applies to various machinery to ensure safe human interventions in potentially hazardous situations.
Purpose and objectives
The primary purpose of the SN EN ISO 14118:2018 standard is to enhance the safety of machinery operations by establishing guidelines that prevent unexpected start-ups. This standard aims to protect operators and maintenance personnel by ensuring that machinery does not initiate unexpectedly, thus minimizing the risk of accidents. By implementing these guidelines, companies can foster a safer work environment, reduce potential injuries, and comply with legal safety obligations. The standard emphasizes the importance of identifying risks associated with machinery and developing adequate measures to mitigate those risks effectively.
Scope: who must comply
SN EN ISO 14118:2018 applies to manufacturers, designers, and suppliers of machinery across various industries, including mechanical engineering, electrical engineering, and sectors utilizing pneumatic and hydraulic systems. Companies involved in the design and operation of machinery that poses risks of unexpected start-up must comply with these safety standards. This includes not only large manufacturing firms but also small and medium-sized enterprises (SMEs) that engage in machinery production or maintenance. The standard is particularly relevant within the context of Environment, Health & Safety (EHS) regulations, ensuring that organizations uphold safety and compliance in their operations.
How SN EN ISO 14118:2018 relates to other standards
Several standards complement or relate to SN EN ISO 14118:2018, enhancing overall safety measures in machinery operations:
- ISO 14119: Focuses on the design principles for interlocking devices associated with guards, ensuring that safety measures are integrated into machinery design.
- SN EN 1037+A1:2008: Addresses the prevention of unexpected start-up of machines and provides safety guidelines for specific machinery applications.
- EU Directive 2006/42/EC: Establishes general safety requirements for machinery in the European Union, offering a framework that includes compliance with ISO standards.
Revision history and current status
SN EN ISO 14118:2018 is the latest revision of the standard, published by ISO in 2018. This revision includes updates that reflect current safety practices and technological advancements in machinery design. Changes in this iteration emphasize the need for comprehensive risk assessments and improved energy disconnection methods, ensuring that procedures are aligned with modern industrial practices. The ongoing relevance of this standard highlights its importance in safeguarding human interactions with machinery.
