Good practice to avoid overfilling of recovery cylinders


Overfilling of cylinders presents a number of risks, the first of which is loss of the contents. In addition to the environmental impact related to the leak into the atmosphere, the dispersion of the refrigerant may cause asphyxiation or other effects related to its escape (e.g. frost burns). A reminder of the precautions to be taken.



1/ Know the regulations in force and respect them (F-Gas II and Waste).

2/ Use an appropriate recovery cylinder : make sure the test pressure of the cylinder is suitable for the fluid to be recovered and when recovering flammable gases, the correct cylinder is used.

3/ Check the allowed maximum fill. Do not exceed the weight stencilled on the cylinder.

4/ Define the maximum quantity that can be introduced into the bottle, and carry out the recovery using scales to be able to control the amount recovered into the bottle.

5/ Fill in the documents identifying the fluid and the quantity recovered in accordance with local regulations.

Caution: Do not heat the bottles (especially with a blowtorch), protect the packaging from direct sunlight, check the ventilation of the vehicle, do not smoke and do not use the telephone (especially with bottles containing flammable fluid).

*Fill factor of used fluid = 80% of the fill factor of new fluid defined by ADR.
