Overview & Statutory Scope
Refrigeration and air conditioning work in 2026 faces new safety regulations regarding low-GWP mildly flammable A2L refrigerants (R32, R454B), heavy rooftop condenser unit rigging, high-pressure nitrogen testing, and electrical controls.
Hierarchy of Hazard Control Measures (2026 Standards)
- A2L Refrigerant Recovery: Spark-proof recovery machine, continuous refrigerant gas sensor, exclusion zones.
- High-Pressure Nitrogen: Regulated pressure testing with safety relief valves up to 40 bar.
- Roof Rigging: Crane lift plan and edge protection for roof packaged units.
Risk Assessment Matrix: Primary Hazards & Mandatory Controls
| Identified Hazard | Mandatory Control Measure |
|---|---|
|
Ignition of mildly flammable A2L refrigerant vapors
|
Use spark-free brushless recovery equipment |
|
Pressure vessel rupture during nitrogen decay testing
|
Always use double-gauge pressure regulator with burst disc |
|
Fall from roof while servicing rooftop chillers
|
Secure rooftop edge guardrails or inertia fall arrestors |
|
Electrocution from 3-phase compressor power
|
Lockout/Tagout 3-phase AC isolator switch |
Mandatory Personal Protective Equipment (PPE) Register
Thermal cryogenic gloves for refrigerant handling
Safety glasses with side shields
Hearing protection during recovery
Hard hat and steel-toe boots
