Concentrated sensitive supplies must be diluted before use. What potential reaction should you be aware of?

• A. Allergic reactions
• B. Thermal burns
• C. Chemical burns
• D. Respiratory distress

Answer: (A)

The main idea is that dilution reduces the overall hazard of concentrated supplies, but allergic reactions remain a possible risk for people who are sensitized to ingredients in those products. Some components, such as fragrances, preservatives, or other sensitizers, can trigger immune responses in susceptible individuals even at diluted levels or after repeated exposure. This means signs like itching, hives, swelling, or even more severe reactions can occur despite proper dilution. In practice, we should still use appropriate PPE and ventilation, monitor for any allergic reactions after use, and respond quickly if symptoms develop. While chemical or thermal burns and respiratory irritation can result from exposure or poor handling, the question highlights allergic reactions because they can occur even when the product is properly diluted and handled.
