To protect against the possibility of frostbite when working with Cryogenic liquids, what PPE should be used?
-
Leather insulated gloves and approved face shield.
-
Rubber gloves and sun glasses.
-
Cotton gloves and contact lens.
Correct Answer
A. Leather insulated gloves and approved face shield.Explanation
When working with Cryogenic liquids, there is a risk of frostbite due to the extremely low temperatures. Leather insulated gloves provide insulation and protection against the cold, preventing frostbite. An approved face shield is also necessary to protect the face from any splashes or contact with the Cryogenic liquid. Rubber gloves and sun glasses do not provide enough insulation and protection, while cotton gloves and contact lens do not provide adequate protection against the cold temperatures. Therefore, the correct PPE to use in this situation is leather insulated gloves and an approved face shield.Rate this question:

When installing a LOTO for a motor, where do you install the lock?
-
On the HOA.
-
On the motor.
-
In the PDC on the breaker.
Correct Answer
A. In the PDC on the breaker.Explanation
When installing a Lockout/Tagout (LOTO) for a motor, the lock is installed in the PDC (Power Distribution Center) on the breaker. This is because the PDC is the central control panel where the power to the motor is controlled. By installing the lock on the breaker in the PDC, it ensures that the power cannot be accidentally or intentionally turned on while maintenance or repairs are being performed on the motor. This helps to prevent any potential accidents or injuries that could occur from the motor being unexpectedly energized.Rate this question:

Normal valve position for inlet, outlet, vent and bypass of a PSV are:
-
Inlet, outlet, vent and bypass locked open.
-
Inlet, outlet locked open, vent and bypass closed.
-
Inlet, outlet locked closed, vent and bypass open.
Correct Answer
A. Inlet, outlet locked open, vent and bypass closed.Explanation
The correct answer is "Inlet, outlet locked open, vent and bypass closed." This means that the inlet and outlet valves of the pressure safety valve (PSV) are open, allowing the fluid to flow through the system. On the other hand, the vent and bypass valves are closed, ensuring that there is no alternative path for the fluid to escape or bypass the PSV. This configuration ensures that the PSV is operating in its normal position, ready to relieve excess pressure when necessary.Rate this question:

You should never purge hydrocarbons with ________.
-
Nitrogen
-
Fuel Gas
-
Air
Correct Answer
A. AirExplanation
Purging hydrocarbons involves removing any potentially flammable or explosive gases from a confined space. Air contains oxygen, which can support combustion and increase the risk of fire or explosion. Therefore, purging hydrocarbons with air is not recommended as it can be hazardous. Nitrogen, on the other hand, is an inert gas that does not support combustion and is commonly used for purging hydrocarbons. Fuel gas, such as natural gas, can also be used for purging as it is less likely to cause combustion compared to air.Rate this question:

What is the Joule-Thompson Effect?
-
Cooling of Gas upon expansion (moving from high pressure to low pressure)
-
Energy transfer from one electrical source to the next
-
Rapid Heating of gas upon compaction or pressurizing.
-
Separation of liquids through heating and pressurizing.
Correct Answer
A. Cooling of Gas upon expansion (moving from high pressure to low pressure)Explanation
The Joule-Thompson effect refers to the cooling of a gas when it expands from a high pressure to a low pressure. This phenomenon occurs due to the intermolecular forces between gas molecules. As the gas expands, the molecules move further apart, and this causes a decrease in temperature. It is an important concept in thermodynamics and is used in various applications such as refrigeration and liquefaction of gases.Rate this question:

When returning valves to normal position after removing a LOTO, what is the correct way to do this?
-
Open the valve as fast as possible.
-
Slowly crack the valve open until flow has started, allow the piping to pressurize then open fully.
-
Open the 50% and walk away.
Correct Answer
A. Slowly crack the valve open until flow has started, allow the piping to pressurize then open fully.Explanation
When returning valves to normal position after removing a LOTO (Lockout/Tagout), it is important to do so in a controlled manner to prevent any sudden surges or pressure build-up. Opening the valve as fast as possible can lead to sudden flow and potential damage to the piping system. Opening the valve slowly, allowing the flow to start, and allowing the piping to pressurize before fully opening the valve ensures a gradual and controlled restoration of normal flow. This approach minimizes the risk of accidents or damage to equipment.Rate this question:

What position must the inlet and outlet of a PSV be into provide overpressure protection?
-
Closed
-
It doesn’t matter
-
Open
-
Locked Open
Correct Answer
A. Locked OpenExplanation
The inlet and outlet of a Pressure Safety Valve (PSV) must be locked open in order to provide overpressure protection. This means that the valve is held in the fully open position, allowing the excess pressure to be safely released from the system. By locking the valve open, it ensures that the valve cannot accidentally close and prevent the necessary pressure relief.Rate this question:

-
Start opening valves and getting the facility back online.
-
Review first out alarm page to determine what the cause was. Verify system is safe to restart and communicate to supervision.
-
Call your supervisor and ask him to figure it out.
Correct Answer
A. Review first out alarm page to determine what the cause was. Verify system is safe to restart and communicate to supervision.Explanation
The correct answer is to review the first out alarm page to determine what the cause was, verify the system is safe to restart, and communicate to supervision. This is the appropriate course of action because it allows for identifying the cause of the ESD activation, ensuring the system is safe before restarting, and informing the relevant authority to provide necessary guidance or instructions. Simply opening valves and getting the facility back online without understanding the cause or ensuring safety could lead to further issues or potential hazards. Asking the supervisor to figure it out without taking any initial steps would delay the resolution process.Rate this question:
