What is the difference between acute and chronic health effects?
Answer: Acute occur from short-term high exposure; chronic develop from prolonged repeated exposure
Acute effects result from short-term high exposure; chronic effects develop from prolonged or repeated exposure.
What does synergistic effect mean in industrial hygiene?
Answer: Combined effect is greater than sum of individual effects
A synergistic effect means the combined toxic effect exceeds the sum of individual effects.
What is the primary purpose of capture velocity in ventilation?
Answer: Providing sufficient air movement to draw contaminants into the exhaust hood
Capture velocity is the air velocity sufficient to draw contaminants into the hood at the point of generation.
Which respirator provides highest protection in IDLH atmospheres?
Answer: Pressure-demand self-contained breathing apparatus
Pressure-demand SCBA has the highest assigned protection factor of 10,000.
What is the action level concept in exposure monitoring?
Answer: A concentration typically half the PEL triggering monitoring and medical surveillance
The action level at 50 percent of PEL triggers monitoring, medical surveillance, and other protective measures.
How does humidity affect heat-related illness risk?
Answer: High humidity increases risk by impairing sweat evaporation
High humidity impairs the primary cooling mechanism of sweat evaporation.
