The responsible machine or process designer no longer considers the production requirements and adds safety systems later, but addresses the two issues as a whole. Legislation demands that the machine or process design meets the necessary safety standards and regulations – it is a legal requirement.
Different types of machines will have different levels of associated risk. These risk levels need to be addressed for the whole machine life span. In particular the requirements at commissioning, application/usage and decommissioning of the machine must be considered.
Risk assessment according to ISO14121 is a series of logical steps that enables designers and safety engineers to examine in a systematic way the hazards arising from the use of machinery so that appropriate safety measures can be selected.
