Final answer:
The claim that corrosive class chemicals are the most commonly used and transported hazardous materials is false; while corrosives are hazardous, they are not the most common type.
Step-by-step explanation:
The statement that corrosive class chemicals are the most commonly used and transported group of hazardous materials is false. Corrosive substances are indeed hazardous and can cause immediate damage to tissues they contact or destroy other materials through chemical reactions. However, they are one type among various categories of hazardous materials, which include toxic, flammable, and reactive substances as well. According to the US Environmental Agency (US EPA), the characteristics of hazardous wastes also include these categories.
Corrosives like hydrochloric acid can be extremely dangerous, causing burns to skin and eyes, and damage to clothing on contact. They are required to be handled with extreme care. While corrosives are significant, they are not the most commonly used or transported hazardous materials as there are many different types of hazardous materials that are more frequently used and transported depending on the industry and application.
