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 at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
1 Scope
This document, together with EN 474-1:2022, deals with all significant hazards, hazardous situations and
events relevant to scrapers as defined in 3.1, except towed scrapers, when used as intended and under
the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A), associated
with the whole life time of the machine as described in EN ISO 12100:2010, 5.4.
This document does not provide performance requirements for safety related functions of control
system(s).
The following significant and relevant hazards are not covered in this document:
— Transmission of power between self-propelled machinery (or tractor) and recipient machinery;
— Laser;
— Lightning.
The requirements of this document are complementary to the common requirements formulated in
EN 474-1:2022. This document does not repeat the requirements of EN 474-1:2022 but supplements or
modifies the requirements for scrapers.
This document is not applicable to scrapers which are manufactured before the date of publication of this
document by CEN.

4 Safety requirements and/or protective/risk reduction measures
4.1 General
4.1.1 Context
Scrapers shall comply with the safety requirements and/or protective/risk reduction measures of this
clause. In addition, the machines shall be designed according to the principles of EN ISO 12100:2010 for
relevant but not significant hazards which are not dealt with by this document.
4.1.2 Specific relation to EN 474-1
Scrapers shall comply with the requirements of EN 474-1:2022, as far as not modified or replaced by the
requirements of this part.
There are general requirements specified in EN 474-1:2022 that are not applicable because the risk
assessment has shown that for scrapers the corresponding hazard does not exist. For scrapers 4.4.2,
4.5.10, 4.6.3, 4.7.3, 4.12, 4.23, 4.24, Annex B, Annex C and Annex D in EN 474-1:2022, are not applicable.
4.2 Operator’s seat
EN 474-1:2022, 4.4.1 shall apply with the addition that the seat shall meet the input spectral class EM2
according to EN ISO 7096:2020.
4.3 Operator’s Controls and Indicators
4.3.1 General
EN 474-1:2022, 4.5 shall apply with the addition stated in 4.3.2 below.
