Job Setup and Scope

Verify whether the job is service, repair, recovery, leak check, installation, or commissioning, and confirm the scope matches the work order and site conditions.
Confirm the system refrigerant is identified as R-454B, R-32, or another approved A2L refrigerant before opening the circuit.
Verify the equipment nameplate, service manual, and refrigerant documentation are available at the job site.
Confirm the person leading the job is qualified to work on A2L refrigerant systems and understands the site-specific hazards.

Area Hazard Controls

Check for open flames, smoking, hot work, energized nonessential equipment, sparking tools, and other ignition sources in the immediate work area.
Verify temporary lighting, fans, vacuums, and portable equipment are appropriate for the area and positioned to avoid ignition risk.
Confirm the space has sufficient natural or mechanical ventilation to prevent refrigerant accumulation during service.
Verify the work zone is barricaded, posted, or otherwise controlled to keep untrained persons away from the hazard area.

PPE and Tools

Verify eye protection, gloves, and any additional PPE required by the task and site risk assessment are being used.
Confirm hoses, gauges, recovery machine, cylinders, and leak-detection equipment are approved for the intended refrigerant and in good condition.
Check for frayed cords, damaged plugs, cracked housings, or other defects that could create an ignition or electrical hazard.
Verify the job has appropriate leak detection equipment and that it has been checked for operation before use.

Refrigerant Charge and System Limits

Confirm the installed or planned refrigerant charge is within the applicable limit for the equipment, room volume, and occupancy conditions.
Record the room or enclosure volume used to evaluate refrigerant charge limits and leak accumulation risk.
Verify the technician has reviewed the applicable charge-limit method and understands the controls required if the limit is approached or exceeded.
Confirm the team knows how to stop work, isolate the area, ventilate, and notify supervision if a refrigerant release occurs.

Pre-Job Safety Actions

Verify electrical and mechanical energy sources are isolated before service begins when the task requires de-energization.
Confirm fire extinguisher, first aid supplies, and any required emergency shutoff or communication devices are immediately accessible.
Verify the team reviewed hazards, controls, stop-work authority, and communication expectations before starting the task.
