QUESTION 4

1. There are several gas cylinders that are under pressure, which are located outside of the

maintenance department. As the safety professional, you have been asked a couple of questions

regarding this issue. Please provide the correct responses, and discuss your recommendations

for any control measures.

a.

The volume of the gas cylinder is 25.7 liters and exerts a pressure of 670 mmHg. If part

of the gas is used, the pressure drops to 595 mmHg. What would be the remaining

volume of gas?

b. One of the cylinder's content is under pressure at 1900 psi (per the gauge) at 70°F. As

the day heats up because of the sun, the temperature increases to 105°F. What is the

pressure at 105°F?
