227
What is the difference in equipment line-up between Q-1 and Q-2?
The difference in equipment line-up between Q-1 and Q-2 typically depends on the operational requirements and readiness levels of the ship. While specific details can vary by ship class and mission, here are some general distinctions:
Q-1 (Full Power): This configuration is used when the ship requires maximum propulsion and power generation capabilities. All main engines, generators, and auxiliary systems are online to ensure redundancy and peak performance.
Q-2 (Split Plant): This setup is used during less demanding operations to conserve fuel and reduce wear on equipment. Only a portion of the main engines and generators are online, while others remain in standby mode.
These configurations are part of the ship's engineering doctrine to balance operational readiness with efficiency.
228
Discuss current Temporary Standing Orders in the engineering plant / ship
Temporary Standing Orders (TSOs) in the engineering plant or ship are directives issued to address specific situations or operational needs that fall outside the scope of standard procedures. These orders are typically issued by the Commanding Officer (CO) or Chief Engineer (CHENG) and are designed to ensure safety, compliance, and operational readiness.
229
Discuss current Departure From Specifications in the engineering plant / ship.
Departure From Specifications (DFS) refers to situations where equipment, systems, or operations deviate from established standards or specifications. These departures are typically documented and approved by the appropriate technical authority to ensure safety and compliance.
230
What are the two different types of DFS? Differences between the two?
Major DFS: This type affects critical aspects such as performance, durability, reliability, maintainability, interchangeability, or safety. It can also impact system design parameters like schematics, flow pressures, temperatures, or compartment arrangements. Major DFS requires higher-level approval due to its potential impact on the ship's operational capabilities.
Minor DFS: This type involves deviations that do not affect the above critical factors. It typically pertains to less significant issues that can be resolved without compromising the ship's performance or safety.
The key difference lies in the severity and impact of the deviation. Major DFS has a significant effect on the ship's functionality or safety, while Minor DFS involves less critical deviations
231

232
What is the governing instruction for submitting DFS? What section?
The governing instruction for submitting a Departure From Specifications (DFS) is NAVSEA Instruction 5400.95G. The specific details regarding the DFS process, including submission and approval, are outlined in Enclosure (4).
233
Requirements for dry-bulb thermometer positioning?
The positioning of dry-bulb thermometers onboard ships is crucial for accurate heat stress monitoring. Here are the key requirements:
Location: Thermometers must be placed at watch and workstations where heat-stress conditions may exist.
Height: They should be mounted at a height that represents the temperature experienced by personnel, typically at chest level.
Ventilation: Thermometers can be placed in or out of the ventilation air stream but must be at least 2 feet away from any supply ventilation terminal or opening.
Material: They should be hung using non-heat-conducting materials like plastic or string, avoiding metal wires.
Avoidance of Heat Sources: Position them to minimize the influence of adjacent heat or cold sources, ensuring they are not in direct contact with hot or cold structural surfaces.
234
What PHEL curves does FSH use for Sounding and Security? In-space watchstanders? Scullery?
The Physiological Heat Exposure Limits (PHEL) curves used onboard Fleet Support Ships (FSH) vary depending on the type of work and environmental conditions. Here's a breakdown:
Sounding and Security: Typically, PHEL Curve II or III is applied, as these roles involve moderate physical activity in potentially warm spaces.
In-Space Watchstanders: Depending on the specific space and activity level, PHEL Curve III or IV may be used, especially in areas with higher heat exposure.
Scullery: Due to the combination of physical activity and heat from dishwashing equipment, PHEL Curve IV or V is often applied.
235
Impact of stack gases and fuel vapors to personnel stay times?
The presence of stack gases and fuel vapors significantly impacts personnel stay times in heat-stress environments. These substances can exacerbate heat stress by reducing air quality and increasing the physiological strain on individuals.
236
Symptoms of heat stress casualties?
Heat Stroke (most severe):
Confusion or disorientation.
Loss of consciousness.
Seizures.
Red, hot, dry skin or excessive sweating.
Very high body temperature.
Heat Exhaustion:
Heavy sweating.
Cool, moist skin.
Headache.
Nausea or vomiting.
Dizziness or lightheadedness.
Weakness or fatigue.
Rapid heartbeat.
Heat Cramps:
Painful muscle cramps, often in tired muscles.
Excessive sweating.
Low salt levels in the body.
Heat Rash:
Skin irritation or "prickly heat."
Red bumps or rash caused by sweat not evaporating properly.
237
How do you calculate Time Weighted Mean?
To calculate the Time Weighted Mean (TWM), you use the formula:
๐๐๐=โ(๐ถ๐ร๐๐)/โ๐๐
Where:
๐ถ๐ is the concentration of the factor (e.g., noise level, chemical exposure) during a specific time interval.
๐๐ is the duration of that time interval.
โ๐๐ is the total duration of all intervals.
Steps:
Divide the workday into intervals: Break the exposure period into smaller time intervals where the concentration is consistent.
Multiply concentration by time: For each interval, multiply the concentration (๐ถ๐) by the duration (๐๐).
Sum the products: Add up all the products from step 2.
Divide by total time: Divide the sum by the total duration of exposure (โ๐๐).
237
What is Time Weighted Mean?
The Time-Weighted Mean (TWM) is a statistical measure used to calculate the average exposure to a particular factor (like noise, heat, or a chemical) over a specified period, typically an 8-hour workday. It accounts for variations in exposure levels during that time by weighting each level according to the duration of exposure.
For example, in industrial hygiene, the TWM is used to determine whether a worker's exposure to noise or hazardous substances complies with safety standards. It ensures that short periods of high exposure are balanced against longer periods of lower exposure to provide an accurate overall assessment.
238
Are surveys required at the hottest part of the day? Why/Why not?
Surveys are not necessarily required at the hottest part of the day, but conducting them during this time can be beneficial for certain assessments, such as heat stress evaluations. Here's why:
Heat Stress Monitoring: The hottest part of the day provides the most extreme conditions, which are critical for evaluating the effectiveness of cooling systems, ventilation, and protective measures.
Realistic Exposure Assessment: Conducting surveys during peak heat allows for a more accurate understanding of personnel exposure and the adequacy of preventive measures.
Operational Impact: Surveys at this time can help identify areas where adjustments are needed to maintain safety and efficiency.
239
What is an Initial Voltage Verification check?
An Initial Voltage Verification (IVV) check is a safety procedure used to confirm the absence of voltage in electrical equipment before performing any work on it.
The IVV process typically involves:
Testing the equipment with a voltage meter to verify it is live.
De-energizing the equipment.
Retesting to confirm the absence of voltage.
Finally, rechecking the meter on a known live source to ensure its accuracy
240
What voltage range is considered a medium risk? High risk?
Medium Risk: Voltages in the range of 50 to 1,000 volts AC or 120 to 1,500 volts DC are generally considered medium risk. These levels can cause serious electrical shocks or burns if proper precautions aren't taken2.
High Risk: Voltages above 1,000 volts AC or 1,500 volts DC are classified as high risk. These levels pose significant dangers, including severe electrical burns, arc flashes, and even fatalities
241
What is a safe-to-start voltage check? When is it required?
A safe-to-start voltage check is a procedure used to verify that electrical equipment is operating within its expected voltage range before starting or energizing it. This ensures the equipment is safe to use and prevents potential damage or hazards caused by abnormal voltage levels.
