Refrigerants and Fire Suppression

Fugitive Emissions from Refrigerants & Fire Suppression Equipment

Refrigeration systems, such as air conditioners, chillers and refrigerators in most buildings and facilities usually contain or consist of hydrofluorocarbon (HFC) compounds, which is a potent GHGs. Refrigerant leaks occur during installation, use and disposal of these systems.

In addition to refrigerants in refrigeration systems, some fire suppression equipments, including hand-held fire extinguishers and total flooding applications, also contain HFCs. HFC leaks occur during testing and deployment of fire suppression equipments.

Refrigerant leaks from refrigeration systems and HFC leaks from fire suppression equipments, both of which are considered Scope 2 fugitive emissions, must be quantified and reported under the LGO Protocol.

The LGO Protocol uses three methodologies for calculating fugitive buildings emissions from HFCs:

Recommended Approach: Mass Balance Method

Alternate Approach 1: Simplified Mass Balance

Alternate Approach 2: Estimation Based on Equipment Inventory and Refrigerant Use
