1. Which of the following is the primary factor contributing to fatigue
in mine workers?
A. Loud noise exposure
B. Long working hours
C. Poor lighting
D. Wearing personal protective equipment
B. Long working hours
Long working hours increase physical and mental strain, reducing
alertness and reaction time, which is the primary contributor to fatigue
in mining operations.
2. Fatigue can impair a worker’s ability to:
A. Follow safety procedures
B. Recognize hazards
C. Operate machinery safely
D. All of the above
D. All of the above
Fatigue affects cognitive function, decision-making, and physical
performance, making workers less able to follow procedures, identify
hazards, and operate equipment safely.
3. Which physiological process is most affected by sleep deprivation?
A. Muscle growth
, B. Cognitive processing
C. Bone density
D. Skin elasticity
B. Cognitive processing
Sleep deprivation primarily impacts cognitive processes such as
attention, memory, and decision-making, all crucial for safe work in
mining.
4. What is a common symptom of fatigue among miners?
A. Increased energy
B. Drowsiness
C. Heightened alertness
D. Rapid reflexes
B. Drowsiness
Drowsiness is a direct and observable symptom of fatigue, often leading
to slower reaction times and increased risk of accidents.
5. Which factor can exacerbate fatigue in night-shift workers?
A. Regular exercise
B. Exposure to daylight
C. Irregular sleep patterns
D. Adequate hydration
C. Irregular sleep patterns
Irregular sleep disrupts circadian rhythms, making it harder for workers
to maintain alertness during night shifts.
6. Microsleeps are best described as:
A. Short periods of deep sleep during work
B. Brief, involuntary lapses in attention due to fatigue
, C. Naps longer than two hours
D. Sleep that occurs only on weekends
B. Brief, involuntary lapses in attention due to fatigue
Microsleeps are brief moments where a fatigued person’s brain shuts
down temporarily, causing attention lapses without conscious
awareness.
7. Which of the following strategies helps reduce fatigue during long
shifts?
A. Skipping meals
B. Taking scheduled breaks
C. Avoiding hydration
D. Reducing sunlight exposure
B. Taking scheduled breaks
Scheduled breaks allow the body and mind to recover temporarily,
reducing cumulative fatigue and maintaining alertness.
8. Which factor can negatively influence sleep quality for miners?
A. Quiet, dark sleeping environments
B. Irregular shift schedules
C. Maintaining consistent bedtime
D. Limiting caffeine intake at night
B. Irregular shift schedules
Irregular shifts disturb natural sleep patterns, making it harder to obtain
restorative sleep, which increases fatigue risk.
9. Which of the following is considered a long-term effect of chronic
fatigue?
A. Improved concentration
, B. Cardiovascular problems
C. Increased reaction speed
D. Enhanced physical endurance
B. Cardiovascular problems
Chronic fatigue is associated with increased stress on the cardiovascular
system, higher blood pressure, and elevated risk of heart disease.
10. Fatigue management programs in mines primarily aim to:
A. Reduce production costs
B. Increase worker alertness and safety
C. Replace machinery with automation
D. Minimize paperwork
B. Increase worker alertness and safety
The primary goal of fatigue management programs is to maintain
alertness and reduce the likelihood of accidents due to tiredness.
11. How does caffeine affect fatigue?
A. It permanently eliminates fatigue
B. It temporarily increases alertness
C. It causes immediate sleepiness
D. It has no effect on the nervous system
B. It temporarily increases alertness
Caffeine stimulates the central nervous system, temporarily reducing
perceived fatigue, but does not replace adequate sleep.
12. Which environmental factor can contribute to fatigue in
underground mines?
A. Adequate ventilation
B. Excessive heat
