Recovery & RecyclingQuestion 218 of 240
To fill a recovery cylinder accurately to the 80 percent limit, a technician should:
a.Watch only the pressure gauge
b.Weigh the cylinder on a scale
c.Feel the cylinder temperature
d.Judge by the sound of liquid
Explanation
The fill level must be determined by weighing the cylinder on a scale, since the 80 percent limit is by weight. Pressure, sound, and temperature do not reliably show how full a cylinder is. Overfilling risks a hydrostatic rupture, so accurate weighing is essential.
