What is the hierarchy of controls in industrial hygiene, from most to least effective?
Answer: Elimination, substitution, engineering controls, administrative controls, PPE
The hierarchy ranks: elimination, substitution, engineering controls, administrative controls, and PPE.
What does TLV-TWA stand for and what does it represent?
Answer: Threshold Limit Value - Time-Weighted Average; the average airborne concentration for a normal 8-hour workday
TLV-TWA represents the time-weighted average concentration for a conventional 8-hour workday and 40-hour workweek.
Which sampling method is preferred for assessing a worker's personal exposure to airborne contaminants?
Answer: Personal sampling using a pump and collection media worn by the worker
Personal sampling with a calibrated air pump and collection media in the worker's breathing zone provides the most accurate assessment.
What is the primary health concern associated with prolonged exposure to respirable crystalline silica?
Answer: Silicosis and increased risk of lung cancer
Prolonged inhalation of respirable crystalline silica causes silicosis and significantly increases lung cancer risk.
What is biological monitoring in occupational health?
Answer: Measuring chemicals or their metabolites in workers' blood, urine, or exhaled air to assess internal dose
Biological monitoring measures biomarkers in workers' specimens to assess the absorbed dose of a substance.
What type of ventilation system captures contaminants at or near their source before they enter the worker's breathing zone?
Answer: Local exhaust ventilation
Local exhaust ventilation captures airborne contaminants at or near the point of generation using hoods, ducts, and fans.
