First, note that the question asks for hazards associated with polyphosphoric acid and references hazard codes from the product data sheet. Since the provided answer list contains a single option, we will analyze that option in isolation.
Option: 'Causes severe skin burns and eye damage.' This statement corresponds to a classic hazard classification for strong acids. In hazard terminology, this is typically captured by the hazard statement H314: 'Causes severe skin burns and eye damage.' Such a descriptor indicates corrosive properties that can damage skin and ocular tissue on contact. The rationale here is that polyphosphoric acid is a concentrated inorganic acid; like other strong acids, it can be corrosive to skin and eyes, leading to burns and irritation or more serious injury if exposure occurs.
Why this is plausible: The SDS for polyphosphoric acid generally lists corrosion as a key hazard, and H314 is a common code used across many inorganic acids to communicate this risk. This aligns with general chemical hygiene principles that corrosive acids require protective equipment and handling precautions to avoid skin and eye contact.
Why this might be incomplete if there were other options: If there were multiple hazard statements or codes (for example, categories related to environmental toxicity, flammability, or inhalation hazards), those would address other dimensions of risk not captured by H314 alone. However, for polyphosphoric acid, the most direct and widely applicable hazard is its corrosivity to skin and eyes, which is precisely what the option states.
In summary, the assertion that polyphosphoric acid 'Causes severe skin burns and eye damage' matches the core corrosive hazard associated with concentrated acids and aligns with hazard coding conventions like H314 in many SDS documents.
