Question 1

The 'hierarchy of controls' in occupational health, from most to least effective, begins with:

Accepted Answer

Elimination of the hazard

Answer

Elimination — physically removing the hazard — is the most effective control because it prevents exposure entirely rather than managing it.

Question 2

Which route of exposure is most important for most occupational chemical hazards?

Accepted Answer

Inhalation

Answer

Inhalation is typically the primary route of occupational chemical exposure because workers breathe workplace air for extended periods.

Question 3

Sick Building Syndrome (SBS) refers to:

Accepted Answer

Acute health symptoms linked to time spent in a building without identified cause

SBS describes situations where occupants experience acute health symptoms associated with time spent in a building, yet no specific cause can be identified.

Question 4

What is the primary purpose of a Material Safety Data Sheet (MSDS/SDS)?

Accepted Answer

To provide chemical hazard and handling information to workers

Answer

Safety Data Sheets communicate the hazards, safe handling procedures, and emergency response information for chemical substances in workplaces.

Question 5

Noise-induced hearing loss (NIHL) in occupational settings is:

Accepted Answer

Permanent and preventable through exposure controls
