Which of the following is an example of an ergonomic hazard in a workplace?
Proper lighting
Repetitive motions
Comfortable seating
Stable work surface
Repetitive motions create continuous strain on muscles and tendons, increasing the risk of musculoskeletal disorders. Proper lighting, comfortable seating, and stable work surfaces are ergonomic controls rather than hazards.
What is the recommended angle at the elbows when typing at a desk?
135 degrees
45 degrees
90 degrees
180 degrees
An elbow angle of about 90° keeps forearm muscles relaxed and minimizes stress on the elbow joint. Deviation from this angle can lead to increased muscle strain and discomfort.
What is the ideal distance between a computer monitor and the eyes?
1 meter
20 cm
50 to 70 cm
10 cm
The recommended distance of 50 to 70 cm (20 - 28 inches) between eyes and monitor helps prevent eye strain and maintains comfortable visual focus. Distances too close or too far can cause neck or eye fatigue.
Which device helps maintain a neutral wrist posture while typing?
Ergonomic keyboard
Trackball mouse
Standard keyboard
Laptop touchpad
Ergonomic keyboards are designed to support a neutral wrist position, reducing ulnar deviation and wrist extension. Standard keyboards and mouse devices do not provide this specialized support.
Which lifting technique best helps prevent back injuries?
Keeping legs straight
Twisting while lifting
Bending at the waist
Squatting with knees and hips
Squatting by bending at the knees and hips keeps the back straight and engages powerful leg muscles, reducing spinal load. Bending at the waist or twisting increases the risk of back injury.
Which factor is a primary risk for developing repetitive strain injuries?
Adequate rest breaks
Forced exertions
Low repetition
Proper footwear
Forceful exertions require more muscle effort and increase tissue loading, making it a primary risk factor for repetitive strain injuries. Low repetition and adequate rest breaks reduce rather than increase RSI risk.
When adjusting an office chair, which position ensures proper knee placement?
Knees locked straight
Knees below feet
Knees at 90 degrees and feet flat
Knees higher than hips
Setting the chair so that the knees form a 90° angle with feet flat on the floor promotes even weight distribution and reduces strain on the lower limbs. Other positions can lead to discomfort or circulation issues.
To reduce glare on a computer screen, what is the best monitor placement?
Above eye level
Close to a lamp
Directly facing a window
Perpendicular to windows
Positioning the monitor perpendicular to windows minimizes direct reflections and glare on the screen. Facing a window or positioning lights improperly can cause distracting reflections.
What is an effective strategy to minimize wrist strain when using a mouse?
Using a standard non-ergonomic mouse
Placing mouse far from body
Keeping mouse close and at same height as keyboard
Using a heavy mouse
Keeping the mouse close at the same height as the keyboard reduces wrist extension and shoulder reach, lowering strain. Placement too far increases awkward postures.
Which break schedule helps reduce musculoskeletal discomfort during computer work?
1-hour break every 2 hours
5-minute break every hour
30 minutes break every 8 hours
No breaks needed
Frequent short breaks help muscles recover and reduce static posture, which decreases fatigue and discomfort. Long continuous work periods without breaks increase risk of strain.
Which ergonomic principle involves alternating tasks to reduce muscle fatigue?
Job enrichment
Specialization
Job enlargement
Job rotation
Job rotation changes tasks and engages different muscle groups, preventing overuse of the same muscles. Other principles focus on expanding or deepening job content rather than alternating tasks.
What adjustment should be made to a workstation to support good posture?
Lower keyboard below elbow level
Adjust chair so feet are flat on floor
Raise monitor above eye level
Keep feet dangling
Feet flat on the floor stabilize the pelvis and support spinal alignment, promoting good posture. Dangling feet or improper chair height can strain the lower back.
In the NIOSH lifting equation, which variable represents the horizontal distance of the load from the body?
Vertical height
Frequency
Asymmetric angle
Horizontal reach
Horizontal reach distance influences the torque on the spine during lifting, making it a key factor in the NIOSH equation. Other variables measure height, repetition, or twisting.
What is the main benefit of using forearm supports at a workstation?
Reduce foot pressure
Relieve wrist and forearm muscle strain
Increase typing speed
Improve back posture
Forearm supports transfer load from wrists to forearms and elbows, reducing muscle fatigue in the hands. They do not directly affect back posture or foot pressure.
Which workstation design feature helps prevent awkward trunk rotation?
Non-adjustable keyboard tray
Swivel chair and movable surfaces
Fixed chair
Heavy desk anchoring
Using a swivel chair and movable surfaces allows workers to turn without twisting their spine, reducing awkward trunk rotation. Fixed setups force twisting to reach items.
A warehouse worker lifts 15 kg objects at a frequency of 6 lifts/min with a horizontal reach of 60 cm. The NIOSH lifting index exceeds 1. What is the best ergonomic intervention?
Increase lift frequency
Raise lift height above shoulder
Encourage faster lifts
Decrease load weight
Reducing the weight decreases the calculated lifting index and lowers spinal loading to safer levels. Increasing frequency or speed would worsen risk, and raising height above shoulder increases strain.
A worker experiences wrist extension beyond 20° during data entry. Which tool redesign best addresses this issue?
Taller desk surface
Higher monitor stand
Angled wrist rest and split keyboard
Standard mouse pad
Angled wrist rests and split keyboards encourage neutral wrist alignment, reducing excessive extension and ulnar deviation. Monitor height and desk surface do not directly correct wrist angle.
For prolonged overhead assembly work, which equipment most effectively reduces shoulder elevation and fatigue?
Lower workbench height
Height-adjustable lift table
Use handheld mirror
Fixed step stool
A height-adjustable lift table brings work into the optimal height zone, minimizing shoulder elevation and fatigue. Fixed stools and mirrors do not dynamically adjust work height.
Which ergonomic assessment tool systematically evaluates postural risk factors for upper body musculoskeletal disorders?
RULA (Rapid Upper Limb Assessment)
AUDIT
SWOT Analysis
Gantt Chart
RULA assesses upper limb postures, forces, and muscle loads to identify musculoskeletal risk factors. The other tools are unrelated to ergonomic posture analysis.
A manufacturing line has high rates of back pain. Which combined strategy best reduces musculoskeletal disorder risk?
Eliminate breaks
Increase shift length
Reduce task variety
Engineering controls and administrative policies
Engineering controls (like adjustable equipment) adjust physical hazards while administrative policies (like job rotation) limit exposure to high-risk tasks. This combined approach effectively reduces MSD risk.
