Question

A disposable cylinder should be reduced to what pressure before scrapping?

1) 0 psig
2) 20 psig
3) 50 psig
4) 80 psig

Answer 1

A disposable cylinder should be held to 0 psig before scrapping to ensure it is fully depressurized and to avoid any explosive hazards during disposal.

Step-by-step explanation:

Before scrapping a disposable cylinder, it is critical to ensure it is depressurized fully for safety reasons. The cylinder must be brought to 0 psig, which stands for pounds per square inch gauge, to ensure there is no residual pressure that could cause harm during the disposal process. This is the safest pressure for scrapping a cylinder to avoid any potential explosive hazards. It is good practice to follow all regulatory guidelines and safety protocols when disposing of such materials to minimize risks.
