F-Gas Regulation: Safety exemptions require clear and shared criteria
The safety exemptions provided for in the F-Gas Regulation require clear criteria to ensure a safe transition to low-GWP refrigerants.
The revision of the EU F-Gas Regulation 2024/573 is accelerating the transition to low-GWP refrigerants , introducing more stringent limits, new marketing bans, and a progressive reduction in available quotas. For the HVAC/R industry, this represents a profound change that affects manufacturers, designers, installers, maintenance technicians, distributors, and end users.
In this scenario, one of the most sensitive issues concerns exemptions related to safety requirements . The transition to alternative refrigerants, in fact, cannot be assessed solely based on GWP: it must also take into account actual installation conditions, applicable technical standards, operator safety, and compatibility with the characteristics of the building or application.
Safety exemptions: why operational guidelines are needed
The new F-Gas Regulation provides for progressive bans for certain categories of equipment , with increasingly lower GWP thresholds. In some cases, however, exemptions may be provided when site or application safety requirements do not allow the use of alternative solutions below the indicated threshold.
The key is to clearly define when and how these exemptions can be applied . Without shared criteria, there is a risk of differing interpretations among Member States, competent authorities, manufacturers, and industry operators, with consequences for the market, installations, and intervention planning.
For professional refrigeration, clarity becomes essential especially in cases where the use of flammable, natural or very low GWP refrigerants requires specific assessments of ventilation, maximum charge, intended use, presence of people, accessibility of the system and maintenance procedures.
Not just GWP: the choice of refrigerant depends on the application context
Reducing the climate impact of refrigerants remains a priority, but safety must be a key consideration. Choosing the most suitable fluid must be part of a broader technical assessment that considers the entire system and not just the GWP value.
Elements to be analyzed include:
- refrigerant safety class ;
- charge limits set by technical standards;
- characteristics of the premises or installation area ;
- presence of ventilation and leak detection systems ;
- accessibility for maintenance and service ;
- compatibility with available equipment and components ;
- actual operating conditions of the plant.
This approach is particularly important in HVAC/R systems where the use of certain alternatives may be difficult for technical or safety reasons. In these cases, the exemption should not be interpreted as a way to slow down the transition, but rather as a tool to ensure that the transition to low-GWP refrigerants occurs in a safe, documented, and technically sustainable manner.
Installers and operators: the burden of technical documentation is growing.
Applying exemptions also requires greater attention to documentation . Installers, maintenance personnel, and operators must be able to demonstrate why a given alternative solution is not safe to use in a specific context, citing technical standards, design assessments, and site conditions.
This requires a more structured role for the entire supply chain . The manufacturer must provide clear information on the equipment and refrigerants that can be used; the designer must correctly assess the application context; the installer must comply with requirements and procedures; the operator must maintain the necessary documentation and ensure consistent management of the system over time.
The F-Gas transition, therefore, does not simply mean new limits and bans. It also brings with it greater technical and documentation responsibility, especially in cases where safety requires specific assessments.
An effective transition requires harmonization and expertise
To avoid application uncertainty, the sector is calling for clear and harmonized operational guidance at the European level . A fragmented management of exemptions could create disparities between markets, slow down decision-making, and complicate investment planning.
For the refrigeration supply chain, the direction remains clear: progressively reduce the use of high-GWP refrigerants and accelerate the adoption of more sustainable solutions . However, the rapid transition must be accompanied by technical expertise, training, availability of suitable products, and clear criteria for cases where safety imposes objective limits.
Safety exemptions therefore represent a technical and regulatory issue that must be carefully managed. If properly applied, they can help make the F-Gas transition more orderly, avoiding both overly permissive interpretations and rigidities that could compromise safety, operational continuity, and plant quality.

FAQ
Because exemptions should remain technical tools for specific cases, not shortcuts to delay the transition to low-GWP refrigerants. Clear criteria help authorities, manufacturers, designers, and installers distinguish situations where a low-GWP alternative is truly unsafe from those where the problem can be solved with appropriate design, certified components, ventilation, charge limits, or mitigation measures.
A derogation can only be justified when the application conditions make the safe use of flammable, toxic, high-pressure, or other specific refrigerants impractical. The assessment must consider the intended use of the premises, the presence of people, accessibility for maintenance, available volumes, ventilation, ignition sources, charging limits, fire safety requirements, and compatibility with applicable technical standards. It is not sufficient to declare that an alternative is more complex: the residual risk and the impossibility of managing it with reasonable technical measures must be demonstrated.
A risk analysis, review of available technical alternatives, justification for refrigerant selection, references to product and installation standards, and data on refrigerant charge, ventilation, compartmentation, leak detection, and emergency procedures are all required. It's also helpful to document the responsibilities of all parties involved, from the manufacturer and designer to the installer and system operator, so that the technical decision can be traced and compliance can be verified.
