What this is
What is a refrigerant leak record?
What is a refrigerant leak record?
A refrigerant leak record documents a loss of refrigerant: how it was detected, the quantity lost, the safety response, the effect on product, the repair and its verification, and whether the loss is reportable. A leak is a safety event, a product event and an environmental release at once, and no single team owns all three unless one record ties them together.
Why does refrigerant loss matter beyond the cost of the gas?
Most commercial refrigerants are potent greenhouse gases, with warming potentials hundreds to thousands of times that of carbon dioxide by mass. A modest leak from a large system can be a meaningful direct emission on its own, and on a cold-chain site it is often the largest scope one source, which is why the record has to reach the GHG inventory rather than stop at the repair.
What has to happen after a refrigerant leak is repaired?
The repair has to be carried out or verified by a certified technician, recovered and recharged quantities recorded, and the system leak-tested again and re-tested within a follow-up window, commonly around thirty days, to confirm the repair held. An un-rechecked repair has fixed a symptom without confirming the cause.
Scope
When is a refrigerant leak record required?
This record covers a loss of refrigerant from an existing system. It is not the place to record emissions from a permitted stack, a stack test result, or the site's overall greenhouse gas position, each of which has its own record.
Use this template when
- A leak is detected by fixed detection, a routine check, a charge shortfall, or by smell or ice formation
- Refrigerant is added to top up a system, itself evidence a leak occurred
- A repair has been carried out and needs its verification test and certification recorded
- A leak needs a call on whether it clears a refrigerant-rule or environmental-release reporting threshold
- The loss needs to be added to the site's greenhouse gas inventory as a direct emission
Do not use it for
- Air Emissions Log, which records emissions from permitted stack sources and control equipment status, not refrigerant systems
- Stack Test Record, which records measured stack emissions against permit limits
- Greenhouse Gas Inventory, which aggregates emissions across scopes; this record feeds it rather than replacing it
- Environmental Complaint Record, for a complaint about site conditions rather than an internal leak event
- Anything outside KnowEnviro, which belongs in the workspace that owns that process
Compliance mapping
Which EPA 40 CFR 82 requirements does this satisfy?
EPA's rules under 40 CFR Part 82 and the F-Gas Regulation attach specific duties to specific moments in the life of a leak, and the record's sections map onto those moments.
| Clause | Requirement | Where it lands |
|---|---|---|
| EPA 40 CFR Part 82, Subpart F | Recordkeeping for refrigerant added, recovered and lost from covered equipment | The leak |
| F-Gas Regulation | Leak check obligation scaled to the CO2-equivalent size of the charge, at a set frequency | Regulatory |
| EPA 40 CFR Part 82, Subpart F | Repair of a leak exceeding the applicable threshold within the required timeframe | Repair and verification |
| EPA 40 CFR Part 82, Subpart F | Follow-up verification test confirming the repair was effective | Repair and verification |
| F-Gas Regulation | Repair, installation and service carried out only by certified personnel | Repair and verification |
| General duty / process safety | Assessment and control of exposure where the refrigerant is toxic or an asphyxiant | Safety response |
| GHG reporting practice | Direct refrigerant emissions included in the scope one inventory | Regulatory |
What it does not cover
- Air Emissions Log, which covers emissions from a permitted combustion or process source, not a refrigeration system.
- Stack Test Record, a measured result against a permit limit, not a fugitive loss from a sealed system.
- Confined space or ammonia release procedure, which governs the immediate safety response and sits alongside this record.
- Work order for the repair itself, which belongs in the maintenance system; this record cites it rather than replacing it.
- Greenhouse Gas Inventory, the aggregated position this record feeds, not a substitute for the individual event.
Global
Refrigerant Leak Record requirements by country
The duty to check for and repair refrigerant leaks is well established across the largest cooling footprints, though the trigger thresholds and certification regimes differ.
40 CFR Part 82, Subpart F
Owners of covered refrigeration and air-conditioning appliances above a charge threshold must repair leaks exceeding a set rate within a set period and verify the repair.
The obligation runs to the owner or operator, and recordkeeping of leak rate calculations and repairs is inspectable evidence of compliance.
F-Gas Regulation
Leak checks at a frequency scaled to the CO2-equivalent tonnage of the charge, with prompt repair and certified personnel required throughout.
Larger, higher-GWP systems are checked more often, and the regulation increasingly pushes installations toward lower-GWP refrigerants.
Retained F-Gas Regulations
Substantially mirrors the EU regime post-transition: scaled leak checks, certified technicians, and recordkeeping of quantities handled.
A UK site cannot assume EU guidance applies unmodified; the retained instrument is the one to cite even where the substance is near-identical.
How to complete it
How to complete a refrigerant leak record, step by step
The fields prompt for a quantity and a repair. What makes the record defensible sits slightly outside what the form asks directly.
A charge shortfall found at service tells you gas is missing, not how much or when. Use metered recharge quantity and a system log to build the percentage-of-charge figure rather than backing into an estimate; the threshold decision depends on that number being right.
Recording that a certified technician did the work is only useful if the certification number is checkable. Entering it at the time, rather than reconstructing it later, is what makes the field worth having when an auditor asks.
The verification window runs from the repair date, not from when someone remembers to check. Raising the follow-up test as a dated task the moment the repair is logged is what stops it becoming overdue.
A small, quickly-repaired seep and a large loss with product and safety consequences do not deserve the same depth of cause analysis. Match investigation level to what happened, and record the reasoning, not just a category.
What auditors find
Most common refrigerant leak record findings
The form nearly always gets completed once a leak is found. The findings concern what happens after the gas is back in.
| Finding | Clause | What fixes it |
|---|---|---|
| Leak rate calculated inconsistently, using estimated shortfall rather than measured recharge quantity. | EPA 40 CFR Part 82, Subpart F | Use metered recharge quantity against full charge to calculate percentage lost. |
| Follow-up verification test not scheduled, or overdue with no record of why. | EPA 40 CFR Part 82, Subpart F | Raise the follow-up test as a dated task the moment the repair is logged. |
| Repair carried out without a certified technician, or certification not recorded. | F-Gas Regulation | Record the technician's certification number at the time of the repair. |
| Cause of the leak recorded as a category with no supporting reasoning. | Investigation practice | Match investigation depth to the size of the loss, and record the reasoning behind the cause. |
| Refrigerant loss not added to the greenhouse gas inventory because it fell below a reporting threshold. | GHG reporting practice | Add every loss to the inventory as a direct emission regardless of any reporting threshold. |
| Leak check frequency not increased for the system after a leak, so the next loss is caught just as late. | F-Gas Regulation | Increase check frequency on the affected system after any confirmed leak, and record the new interval. |
Case in point
Case in point: the leak that was reported twice, in two different registers
A cold store recorded a leak from a chill unit as a maintenance work order: gas topped up, unit isolated, technician certified, follow-up test booked. Environment separately ran its quarterly reconciliation of refrigerant purchased against refrigerant expected in service, spotted the shortfall, and opened a second investigation into the same event without knowing maintenance already had one open.
The two records disagreed on quantity lost, because maintenance used the recharge amount and environment used a purchasing reconciliation covering a wider period with other systems mixed in. Reconciling the figures took longer than the repair had, and the GHG inventory entry was delayed until it settled. Neither number was wrong; there was no single record either team trusted, which is the gap a shared leak record closes.

From a document you fill in to a programme that runs itself
The record is straightforward to fill in once the gas is back in the system. What slips is the follow-up test, the certification evidence, and the GHG inventory entry that depends on it existing.
Holds the leak record against the site's refrigerant register, checks quantity against reconciliation figures, and pushes confirmed losses into the GHG inventory.
Watches for toxic or asphyxiant refrigerants and confirms the safety response, evacuation, detection, exposure, was worked through before the record closes.
Checks the certification claimed against the technician's competency record, so a certified-repair field is backed by something checkable.
Raises the follow-up test as a dated task at the point of repair, and flags a record where the window has passed with no result entered.

Refrigerant Leak Record definitions and key terms
- Leak rate
- The quantity of refrigerant lost expressed as a percentage of the system's full charge, used to test against a regulatory or internal threshold.
- F-Gas
- Fluorinated greenhouse gas, the family of high-global-warming-potential refrigerants covered by leak check, certification and phase-down rules.
- Global warming potential (GWP)
- How much a given mass of gas warms the atmosphere relative to the same mass of carbon dioxide over a set time horizon.
- Refrigerant recovery
- Removing refrigerant from a system and capturing it rather than venting it, required before most service work and always after decommissioning.
- Verification test
- A leak test carried out after a repair, and again after a follow-up interval, to confirm the fix held under normal operating conditions.
FAQ
Frequently asked questions about refrigerant leak record
Does every top-up of refrigerant need a leak record?+
Yes in substance, because a top-up is evidence a leak occurred even if the point has not yet been found. Recording only confirmed, located leaks misses the small losses a leak-rate threshold exists to catch before they become large ones.
How is the leak rate threshold decided?+
Thresholds are typically set against the annual leak rate as a percentage of the system's full charge, with the rate and route depending on jurisdiction and CO2-equivalent charge size. The record should hold both the raw quantity lost and the percentage so the threshold call can be checked later.
Why does the follow-up test matter if the initial repair test passed?+
A repair can hold under conditions immediately after the work and fail once the system returns to normal running load. The follow-up window exists to catch that failure mode, and skipping it converts an apparent repair into an unverified one.
Is a small ammonia leak still a major event?+
Potentially, yes. Ammonia is toxic at low concentrations, and the safety response, evacuation, detection, exposure assessment, has to be worked through regardless of the eventual quantity lost. The environmental and product questions come after.
Does a leak below the reporting threshold still need to be reported anywhere?+
It still needs to reach the greenhouse gas inventory as a direct emission, and the check frequency on the affected system should be reviewed, even with no external notification triggered. Below-threshold is not the same as without consequence.
Who should be the second signature on the record?+
Pairing the engineering signature with an environmental lead reflects that a refrigerant leak is both a maintenance event and an environmental release, needing sign-off from both perspectives rather than either alone.
