For which of the following is grease on the hands or gloves most hazardous?

Question

Quizplus · Accepted Answer

Grease or oil on the hands or gloves is most hazardous when handling oxygen cylinders because oxygen supports combustion. If grease or oil comes into contact with high concentrations of oxygen, it can ignite spontaneously, leading to a fire or explosion. This is not as significant a risk with fuel gases like acetylene, MAPP gas, or propane, where the primary hazard is the fuel itself, not the oxidizer.
