In terms of safety ratings, what does a high toxicity letter indicate?

• A. Less dangerous substance
• B. More dangerous substance
• C. Lower flammability
• D. Higher evaporation rate

Answer: (B)

A high toxicity letter refers to the classification of a substance based on its potential hazards to human health. When a substance is rated with a high toxicity letter, it signifies that the material poses greater risks and can have severe health effects, even in relatively small quantities. This can include acute effects such as poisoning or chronic effects, such as long-term health issues upon exposure. Understanding toxicity is essential for ensuring safety in environments where such substances are used or stored. It emphasizes the importance of using protective equipment and following safety protocols effectively to minimize exposure and potential harm. Other options misinterpret the safety implications. For instance, less dangerous substances would warrant a low toxicity rating, while flammability relates to the likelihood of a substance igniting rather than its toxicity. Similarly, evaporation rate pertains to how quickly a liquid turns to vapor, which does not directly correlate with a substance's toxicity rating.
