Substitution is defined as which hazard-control approach?

• A. Replacing a hazardous chemical with a less hazardous one
• B. Using PPE to manage hazard
• C. Increasing ventilation
• D. Training employees

Answer: (A)

Substitution means removing the hazard at its source by swapping the hazardous chemical or material for a less hazardous alternative. By making the change at the source, you reduce or eliminate the potential for exposure before it happens, which is why this approach is prioritized in risk control. So replacing a hazardous chemical with a less hazardous one is substitution. Using PPE, increasing ventilation, or training employees are important controls, but they act after the hazard exists or exposure is possible rather than eliminating the hazard itself.
