Which body systems are primarily affected by musculoskeletal disorders (MSDs)?
Answer: Muscles, tendons, ligaments, nerves, and bones
MSDs affect the musculoskeletal system, including muscles, tendons, ligaments, nerves, cartilage, and intervertebral discs.
Vibration-induced white finger (VWF) is primarily associated with exposure to:
Answer: Segmental vibration from hand-held power tools
VWF (Hand-Arm Vibration Syndrome) is caused by segmental vibration transmitted through hand-held power tools, damaging blood vessels and nerves in the fingers.
In the hierarchy of controls for ergonomic hazards, which method is considered MOST effective?
Answer: Engineering controls (elimination/substitution)
Engineering controls, particularly elimination and substitution, are most effective because they remove or reduce the hazard at its source rather than managing worker exposure.
Lateral epicondylitis (tennis elbow) is characterized by pain and inflammation at the:
Answer: Lateral epicondyle of the elbow
Lateral epicondylitis involves inflammation of the tendons attached to the lateral epicondyle of the humerus, commonly caused by repetitive wrist extension and gripping.
In the absence of a specific OSHA ergonomics standard for general industry, which regulatory mechanism is used to cite ergonomic hazards?
Answer: The OSHA General Duty Clause (Section 5(a)(1))
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.
Anti-fatigue mats are primarily used in the workplace to:
Answer: Reduce discomfort and fatigue from prolonged standing
Anti-fatigue mats reduce leg and back fatigue by providing cushioning that encourages subtle muscle movement, improving circulation for workers who stand for extended periods.
What does the acronym 'CTD' stand for in occupational health?
Answer: Cumulative Trauma Disorder
CTD (Cumulative Trauma Disorder) refers to injuries caused by repeated microtrauma over time, encompassing conditions such as carpal tunnel syndrome, tendinitis, and bursitis.
