(Main)Refrigerating systems and heat pumps - Safety and environmental requirements - Part 3: Installation site and personal protection
General Information
- Abstract
This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.
The term "refrigerating system" used in this European Standard includes heat pumps.
This Part 3 of the European Standard is applicable to the installation site (plant space and services). It specifies requirements on the site for safety, which may be needed because of, but not directly connected with, the refrigerating system and its ancillary components.
This standard applies:
a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. ISO 13043;
b) to secondary cooling or heating systems;
c) to the location of the refrigerating systems;
d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity.
Systems using refrigerants other than those listed in of FprEN 378-1:2016, Annex E are not covered by this standard.
This standard does not apply to goods in storage.
This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.
This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.
This standard also applies in the case of the conversion of a system for another refrigerant type, in which case conformity with the relevant clauses of parts 1 to 4 of the standard shall be assessed.

For gas fired refrigeration systems specific measures may be required including local regulations. 5.7 Exterior openings of the machinery room Exterior openings shall not be situated within 2 m of building emergency exit staircases or other building openings, e.g. windows, doors, ventilation inlets. 5.8 Piping and ducting All piping and ventilation ducting that passes through walls, ceiling and floors of machinery rooms, shall be sealed where it passes through the walls ceiling or floors. The seal shall have at least the same fire resistance as the walls, ceiling or floor. NOTE 1 Discharge pipes from relief devices may diffuse the charge into the air by adequate means but away from any air intake to the building or discharge into an adequate quantity of a suitable absorbing material. NOTE 2 Relief devices for refrigerants in group A1 can discharge into the machinery room provided the system charge is less than the limits set in EN 378–1:2016, Annex C. Such discharges of refrigerant should take place so that persons and property are not endangered. 5.9 Normal lighting Fixed lighting shall be selected and positioned in spaces containing refrigerating equipment to provide adequate illumination for safe operation. The illumination level and location shall be as required by national regulations. Filament light bulbs shall be protected by “splash safe“ covers (EN 60529 IPX 4) in machinery rooms containing R-717 refrigerating systems. 5.10 Emergency lighting A fixed or portable emergency lighting system shall be provided, adequate to allow operation of controls and evacuation of personnel, when normal lighting fails. The illumination level and location shall be as required by national regulations. 5.11 Dimensions and accessibility The dimensions of the machinery room shall allow easy installation and sufficient room for service, maintenance, operation, repair and disassembly of the refrigerating equipment, including sufficient space for persons wearing personal protection equipment. If necessary, catwalks and fixed ladders shall be provided in order to avoid standing or walking on piping, fittings, their supports and supporting structures and on components during the operation, maintenance, inspection and repair of the refrigerating system. There shall be clear headroom of at least 2,1 m below equipment situated over gangways and permanent work places. The requirements for work staging shall be according to EN ISO 14122-2. NOTE Headroom is defined by 2,1 m above the walking surface. SIST EN 378-3:2017
The assessment according to EN 60079-10-1 considering the LFL and type of release may conclude that the hazardous area is of negligible extent. Refer to Clause 7 for requirements regarding electrical installation. 5.14.2 Location 5.14.2.1 General The machinery room shall be located in accordance with local and national regulations. NOTE
Requirements may depend on the amount of charge in the refrigerating system. SIST EN 378-3:2017
