SHS Ergonomics & Musculoskeletal Disorders 3

Question 1

Which body systems are primarily affected by musculoskeletal disorders (MSDs)?

Accepted Answer

Muscles, tendons, ligaments, nerves, and bones

Answer

MSDs affect the musculoskeletal system, including muscles, tendons, ligaments, nerves, cartilage, and intervertebral discs.

Question 2

Vibration-induced white finger (VWF) is primarily associated with exposure to:

Accepted Answer

Segmental vibration from hand-held power tools

Answer

VWF (Hand-Arm Vibration Syndrome) is caused by segmental vibration transmitted through hand-held power tools, damaging blood vessels and nerves in the fingers.

Question 3

In the hierarchy of controls for ergonomic hazards, which method is considered MOST effective?

Accepted Answer

Engineering controls (elimination/substitution)

Answer

Engineering controls, particularly elimination and substitution, are most effective because they remove or reduce the hazard at its source rather than managing worker exposure.

Question 4

Lateral epicondylitis (tennis elbow) is characterized by pain and inflammation at the:

Accepted Answer

Lateral epicondyle of the elbow

Answer

Lateral epicondylitis involves inflammation of the tendons attached to the lateral epicondyle of the humerus, commonly caused by repetitive wrist extension and gripping.

Question 5

In the absence of a specific OSHA ergonomics standard for general industry, which regulatory mechanism is used to cite ergonomic hazards?

Accepted Answer

The OSHA General Duty Clause (Section 5(a)(1))

Answer

The General Duty Clause requires employers to provide a workplace free from recognized hazards, including ergonomic hazards, and is used by OSHA in the absence of a specific ergonomics standard.
