Introduction
The adoption of refrigerants with low Global Warming Potential, in response to concerns about the
effect of some fluorocarbons on climate, has raised the profile of fluids which were previously limited in
their use due to flammability. As the industry moves towards greater use of low GWP flammable
refrigerants, in particular from flammability class A3, it is important to ensure that operation, service
and decommissioning practices also change to support this technology transition.
The need for technical specifications for all stakeholders in operation and service is particularly
important.
The purpose of this document is to provide information to ensure acceptable risk levels when applying
flammable refrigerants.
This document therefore provides technical specifications to the companies and individuals directly
involved in activities at the worksite; the owner, his operational staff that provide routine maintenance,
subcontractors that undertake specialist service work of various types and decommissioning
contractors.

4 General
The instructions shall be followed for the operation, servicing, maintenance, repair and
decommissioning of refrigeration, air conditioning and heat pump equipment.
The manufacturer and the installer of the equipment transfer the responsibilities for the equipment to
the operator, according to the contract conditions between those parties.
The operator also assumes the responsibilities of the manufacturer when:
— the intended function of the equipment, already placed on the EU market, is modified; or
— the technical details are modified, in particular with regards to respecting charge size limits and
associated risk mitigation measures; or
— the compliance is impacted because the instructions provided for the equipment were not followed.
The following documents contain useful information:
— EN 378-2 provides information on instructions regarding operation and maintenance;
— EN 60335-2-40:2003 provides information on procedures additional to usual information for air
conditioning and heat pump equipment repair, maintenance and decommission procedures when
an appliance with flammable refrigerants is affected. (EN 60335-2-40:2003, Annex A);
— EN 378-4 provides information regarding the operation, maintenance, repair and recovery;
— EN 60079-14 contains the specific requirements for the design, selection, erection and initial
inspection of electrical installations in, or associated with, explosive atmospheres;
— EN 60079-17 covers factors directly related to the inspection and maintenance of electrical
installations within hazardous areas only, where the hazard could be caused by flammable gases,
vapours, mists, dusts, fibres or flyings.
The employer of the worker shall carry out a risk assessment.
NOTE Further information can be found in Directive 99/92/EC.
It is the responsibility of the employer to ensure the safety and health of workers in every aspect
related to the work. The employer shall provide instructions, training, and personal protective
equipment to enable workers to work safely with flammable refrigerants.
Persons working on refrigerating systems containing flammable refrigerants shall have competence in
safety aspects of flammable refrigerant handling. The personnel charged with the operation,
supervision and maintenance of the refrigerating system shall be adequately instructed and competent
with respect to their tasks, as well as the risk mitigation measures to be observed, and the p
