Which option is NOT a recommended way for employees to control exposure routes?

• A. Refusing to work in areas you're uncomfortable with
• B. Using ventilation
• C. Wearing PPE
• D. Substituting materials to reduce toxicity

Answer: (A)

Controlling exposure routes means using measures that actively reduce how workers come into contact with hazards—by removing or lowering the hazard itself, removing contaminated air, or providing a protective barrier. Using ventilation is an engineering control that reduces inhalation exposure by moving or diluting fumes away from the worker. Wearing PPE creates a barrier to skin, eyes, and sometimes inhaled contaminants, lowering the risk of exposure. Substituting materials to reduce toxicity tackles the hazard at the source, so the level of risk is inherently lower for everyone. Refusing to work in areas you’re uncomfortable with, while an important personal safety decision in hazardous situations, isn’t a standard exposure-control method; it doesn’t actively reduce exposure routes across the work environment or the process.
