Recovery & RecyclingQuestion 234 of 240
Storing a filled recovery cylinder in a hot vehicle trunk in summer is dangerous mainly because:
a.The refrigerant will lose purity
b.Rising temperature raises cylinder pressure and can lead to rupture
c.The color will fade
d.The valve will corrode
Explanation
Heat raises the pressure inside a cylinder, and an overfilled or very hot cylinder can rupture, which is why cylinders must stay below 125°F and be filled to no more than 80 percent. Store cylinders cool, upright, and secured. A hot trunk can push a marginal cylinder past its safe limit.
