Refrigerant charging: energy sources and direct controls

Charging refrigerant handles pressurised chemical under pressure with asphyxiation and cold-burn exposure.

High-energy check

Treat refrigerant work as high energy. Pressure and chemical energy are both present and neither is calculated by this tool.

This task's main energy sources are not calculated by this tool. Use the trigger checks below and competent-person verification.

Trigger checks

Chemical
Harmful, reactive, flammable, corrosive or toxic substances.
Pressure
Compressed gas, liquid, hydraulic, pneumatic or vacuum energy.
Thermal
Heat, cold, flame, steam, sparks or thermal stress.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Ventilation and gas detection are confirmed in the space.
Charging equipment is rated for the refrigerant and pressure.
PPE for cold burns and chemical contact is worn.
Cylinder restraint and valve protection are in place.
Escape route and emergency response are known before starting.
Stop if detection alarms or ventilation fails.

For your SPA or pre-start

State the refrigerant type and quantity, the ventilation and detection in the space, the PPE requirement and the emergency response arrangement.

Limitations: This tool supports planning and verification only. It does not replace competent risk assessment, legal duties, employer procedures, client requirements or competent supervision.
