Safety of machinery - Minimum gaps to avoid crushing of parts of the human body
ISO 13854:2017 enables the user (e.g. standard makers, designers of machinery) to avoid hazards from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method.
ISO 13854:2017 is applicable to risks from crushing hazards only and is not applicable to other possible hazards, e.g. impact, shearing, drawing-in.
NOTE For impact, shearing, drawing-in hazards, additional or other measures are to be taken

This document is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety:
Others can be affected by the level of machinery safety achieved with the means of the document by the abovementioned stakeholder groups:
- machine users/employers (small, medium and large enterprises);
- machine users/employees (e.g. trade unions, organizations for people with special needs);
- service providers, e.g. for maintenance (small, medium and large enterprises);
- consumers (in case of machinery intended for use by consumers).
The abovementioned stakeholder groups have been given the possibility to participate at the drafting process of this document.
In addition, this document is intended for standardization bodies elaborating type-C standards.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requirements of that type-C standard take precedence.
According to ISO 12100, in general, machinery is said to be safe if it can perform its function, be transported, installed, adjusted, maintained, dismantled and disposed of under the conditions of its intended use without causing injury or damaging health.
One method of avoiding the hazard of crushing of parts of the human body is to make use of the minimum gaps of this document.
In specifying minimum gaps, a number of aspects have to be taken into consideration, such as
