Which statement about EC is true regarding mixing hazards?

• A. Flammable
• B. Amount of AI increases mixing hazard
• C. Easily absorbed through skin
• D. Non-abrasive

Answer: (B)

The risk in mixing ECs is driven by how concentrated the active ingredient is. Emulsifiable concentrates are concentrated liquids that are diluted with water for use, and the more active ingredient present, the greater the potential harm if there’s splashing, skin contact, or inhalation during the mixing process. Higher AI means a more potent dose can affect you or bystanders, so the mixing hazard rises with the amount of active ingredient. That’s why this option is the best: it directly ties the hazard level to the concentration you’re handling, which is the core factor when you’re preparing these products. Other statements aren’t reliable across all ECs. Flammability can depend on the solvent system used in a particular product, so not every EC is inherently flammable. Skin absorption varies by chemical, so you can’t assume ECs are easily absorbed through skin in all cases. And “non-abrasive” isn’t a relevant measure of mixing hazard. The key point for safety is that increasing AI concentration increases the potential harm during mixing, reinforcing the need for proper PPE, ventilation, and careful handling.
