Question 1

In occupational health, 'secondary prevention' of work-related conditions refers to:

Accepted Answer

Early detection and prompt treatment of work-related conditions to minimize disability before they become disabling

Answer

Secondary prevention focuses on identifying work-related conditions early through health surveillance and screening, then intervening promptly to stop progression and prevent permanent disability.

Question 2

At what occupational noise exposure level does OSHA require employers to implement a hearing conservation program?

Accepted Answer

85 dB time-weighted average over an 8-hour work shift (OSHA action level)

Answer

OSHA requires hearing conservation programs — including monitoring, audiometric testing, hearing protection, and training — when TWA noise exposures reach the 85 dB action level.

Question 3

What is the primary goal of an occupational health surveillance program in an industrial setting?

Accepted Answer

To monitor workforce health trends at a population level to detect and control work-related illnesses early

Answer

Occupational health surveillance systematically collects and analyzes health data across the workforce to identify patterns of work-related illness and inform targeted prevention and control strategies.

Question 4

Which US federal agency is responsible for setting and enforcing legally binding workplace exposure limits for toxic substances?

Accepted Answer

OSHA — Occupational Safety and Health Administration

Answer

OSHA is the federal agency with authority to set, enforce, and update mandatory permissible exposure limits and other workplace safety and health standards under the OSH Act of 1970.

Question 5

What does OSHA's 'incidence rate' metric measure in occupational injury and illness recordkeeping?

Accepted Answer

The number of new injury or illness cases per 100 full-time equivalent workers during a year

Answer

OSHA's incidence rate formula normalizes injury and illness data to 100 full-time equivalent workers, enabling valid comparisons of safety performance across facilities of different sizes.
