Final answer:
The statement is true as the corrosive pictogram indicates both a physical danger and a potential threat to health. Corrosive substances can harm materials and living tissues, and some can also be poisonous. The NFPA 704 diamond symbol helps identify these hazards, including corrosivity, in the workplace or laboratory.
Step-by-step explanation:
True or false: the corrosive pictogram can identify a physical danger, but also as a threat to health? The statement is true. A corrosive substance is capable of causing damage to tissues, materials or the environment by chemical action. The corrosive pictogram is used to signal this physical danger but also serves as a warning for potential health risks. In fact, a substance that is corrosive can also be a poison, presenting serious health threats upon contact or inhalation.
The National Fire Protection Agency (NFPA) 704 Hazard Identification System uses a diamond symbol to classify hazards associated with various substances. This includes providing information on flammability, reactivity, health risks, and more. Specifically, the blue diamond indicates health hazards, while the white diamond at the bottom can mark a material as corrosive amongst other special hazards. The hazards are rated from 0 (no hazard) to 4 (extremely hazardous), reflecting their potential for causing harm or damage.
