What should be done if your Personal Monitor alarms high on H2S?
-
Ignore it. We do not have H2S.
-
Evacuate the area, inform the control room operator, supervisor, and control access to the area.
-
Reset your Monitor.
-
Run as fast as you can.
Correct Answer
A. Evacuate the area, inform the control room operator, supervisor, and control access to the area.Explanation
If your Personal Monitor alarms high on H2S, it is important to evacuate the area immediately to ensure safety. You should inform the control room operator and supervisor about the situation so that they can take appropriate measures. Additionally, controlling access to the area is necessary to prevent others from entering and being exposed to the high levels of H2S. Resetting your monitor or running away is not the correct response in this situation.Rate this question:

What hazard is associated with Iron Sulfide in the powder form?
-
Reacts with Oxygen to spontaneously combust
-
Reacts with Oxygen to release Cyanide
-
Reacts with Water to spontaneously combust
-
Reacts with Water to release Cyanide
Correct Answer
A. Reacts with Oxygen to spontaneously combustExplanation
Iron sulfide in powder form is associated with the hazard of reacting with oxygen to spontaneously combust. This means that when iron sulfide powder comes into contact with oxygen, it can ignite and burn without the need for an external ignition source. This combustion reaction can occur rapidly and without warning, making it a significant hazard in certain environments.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:

A breaker in the PDC trips, what do you do?
-
Open the panel and inspect.
-
Rack breaker to energized position.
-
Call I and E tech to verify breaker is operable and have them reset it. Never reset a tripped breaker without assistance from an I and E tech.
Correct Answer
A. Call I and E tech to verify breaker is operable and have them reset it. Never reset a tripped breaker without assistance from an I and E tech.Explanation
The correct answer suggests that when a breaker in the PDC (Power Distribution Center) trips, it is important to call an I and E (Instrumentation and Electrical) technician to verify if the breaker is operable and have them reset it. It emphasizes the importance of not resetting a tripped breaker without assistance from an I and E technician, indicating that it could be potentially dangerous to do so.Rate this question:

After removing a LOTO what must be done with the valves?
-
Place valves in normal operating position.
-
Leave closed until someone says to operate the valves.
-
Open all valves.
Correct Answer
A. Place valves in normal operating position.Explanation
After removing a LOTO (Lockout-Tagout), it is important to place the valves in their normal operating position. This ensures that the equipment or system can resume its regular functioning. Leaving the valves closed until someone instructs to operate them may cause delays or disruptions in the workflow. Opening all valves immediately after removing the LOTO can be dangerous if there are any residual pressures or hazardous materials present. Therefore, placing the valves in their normal operating position is the appropriate step to take.Rate this question:
