European foreword
This document (prEN 17969:2023) has been prepared by Technical Committee CEN/TC 151
“Construction equipment and building material machines - Safety”, the secretariat of which is held by
DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
Introduction
This document is a type C standard as stated in EN ISO 12100.
This document is of relevance in particular for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned 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 above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document. When provisions of this type C standard are
different from those which are stated in type A or B standards, the provisions of this type C standard take
precedence over the provisions of the other standards, for machines that have been designed and built
according to the provisions of this type C standard.
When operating earth-moving machinery used in contaminated areas, the operator can be exposed to
hazardous agents such as chemical agents in the form of dust, aerosols, gases or vapours or biological
agents in the form of aerosols. Protective ventilation systems of earth-moving machinery providing
protection against these hazardous agents can reduce operator exposure to airborne contaminants
present in contaminated areas.
The objective of this document is to improve the operator protection by using the protective ventilation
systems of earth-moving machinery used in contaminated areas. For this purpose, this document
specifies requirements, test procedures and the operator information to be provided, in particular with
regard to installation, use and maintenance operations.
1 Scope
This document is applicable to protective ventilation systems to provide breathing air to operator's
stations on earth-moving machinery used in contaminated areas. Its purpose is to limit the exposure of
the operator (driver) to hazardous agents when earth-moving machinery is used in contaminated areas.
This document describes requirements, test procedures and information to be provided by the
manufacturer for protective ventilation systems to provide breathing air to operator's stations on earth-
moving machinery used in contaminated areas.
This document gives additional requirements to the common safety requirements of EN 474-1 “Earth-
moving machinery – Safety – Part 1: General requirements” and to the machine specific parts of the
EN 474 series.
This document does not repeat the requirements from the EN 474 series but adds or replaces the
requirements as applicable for Earth-moving machinery.
This document does not cover:
— the safety requirement to be used for any specific application;
— the relevant filter performance or filter class for any particular application;
— the actual cab performance in the field application;
— the filtration performance in the field application;
— the field durability of filters.
This document is not applicable to protective ventilation systems which are manufactured before the
date of its publication as an EN.
