Question restatement: What are the hazards associated with polyphosphoric acid? (use the hazard codes from the product data sheet available through SigmaAldrich)

Given answer: "Causes severe skin burns and eye damage."

Option-by-option analysis:

- Option provided: "Causes severe skin burns and eye damage." This statement aligns with standard hazard statements used for corrosive acids in SDS documents. Specifically, many hazardous acids carry the hazard statement H314, which reads: 'Causes severe skin burns and eye damage.' This reflects the corrosive nature of polyphosphoric acid and its ability to cause tissue injury upon contact with skin or irritation to the eyes. Therefore, this option is consistent with the expected hazard classification for a corrosive acid and is correct as a descriptor of the key hazard.

- Absence of other options: The prompt indicates there should be multiple answers, but no answer options are provided. Because no other risk statements or codes are listed to evaluate, we cannot assess alternative or additional hazards (for example, statements that might reference inhalation hazards, environmental hazards, or specific GHS codes beyond H314). In a complete SDS-based assessment, one would compare all listed hazard statements (e.g., H314 for skin and eye corrosion, possibly H290 if capable of releasing/producing corrosive vapors, etc.) to determine a full hazard profile.

Rationale on why this type of hazard is plausible: Polyphosphoric acid is a strong inorganic acid with high corrosivity, which typically results in local tissue damage upon exposure. The primary and most universally applicable hazard statement for such substances is the risk of severe skin burns and eye damage, which is captured by H314 in the GHS framework.

Why the statement could be insufficient on its own: While H314 captures the most conspicuous hazard, a complete hazard communication often includes additional statements about flammability, inhalation risks, environmental hazards, or compatibility concerns with water or bases, depending on the composition and concentration. Since those other statements are not present in the provided data, we cannot enumerate them here.

In summary, the given statement accurately reflects the core corrosive hazard expected for polyphosphoric acid as indicated by standard SDS hazard classifications. The missing options prevent a full, multi-statement analysis, but the stated hazard is a valid and central descriptor of its hazards.
