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 the 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.
While producing this document it was assumed that, due to the European regulations on the approval of
vehicles for use on public roads, fire fighting vehicles still comply with:
— EMC requirements;
— cyber security requirements.
Therefore, EMC and cyber security are not further considered in this document.
1 Scope
1.1 This document specifies the minimum requirements for safety and performance of some optional
specific permanently installed equipment on firefighting and rescue service vehicles, operated by trained
persons, as designated in EN 1846-1:2011 and specified in EN 1846-2:2024.
NOTE 1 Categories and mass classes of these vehicles are given in EN 1846-1:2011.
NOTE 2 Vehicle means ground vehicles which can also drive on rails and amphibious vehicles.
The permanently installed equipment covered by this document is given below:
— water installation;
— additive installation;
— monitor;
— equipment gantries;
— demountable systems.
This document covers also the use of wireless control systems.
NOTE This document is assumed to be read in conjunction with any national regulations in force for vehicles
using the public roads and with any EU Directives and associated EFTA regulations in force relevant to vehicles and
their equipment.
For the purposes of this document, the normal ambient temperature range is - 15 °C to + 40 °C.
For equipment to be used at temperature outside this temperature range, the particular temperature
range is specified by the user. A risk assessment determines any need for additional precautions.
1.2 This document does not deal with the following types of equipment:
— all control systems outside of the cabin related to hook arm system;
— provisions for non-firefighting removable equipment driven by PTO.
1.3 This document deals with the technical requirements to minimize the hazards listed in Annex A which
can arise during operational use, routine checking and maintenance of firefighting and rescue service
vehicles.
It does not cover the hazards generated by:
— non-permanently installed equipment i.e. portable equipment carried on the vehicle;
— use in potentially explosive atmospheres;
— commissioning and decommissioning;
— noise (as permanently installed equipment cannot be operated separately from the vehicle, this
hazard is covered in EN 1846-2:2024);
— electromagnetic compatibility;
— cyber security;
— cyber safety.
Additional measures not dealt with in this document can be necessary for specific use (e.g. fire in natural
environment, flooding, etc.).
