What are the hazards associated with acetophenone? (use the hazard codes from the product data sheet available through SigmaAldrich)

Question

Question restatement: You are asked to identify the hazards associated with acetophenone, using hazard codes from the SigmaAldrich product data sheet. The prompt provides two answer statements to evaluate:

Option A: Harmful if swallowed.
Option B: Causes serious eye irritation.

Analysis of Option A — Harmful if swallowed:
- This phrasing corresponds to the hazard statement H302 ( Harmful if swallowed ) in many chemical safety data sheets. Acetophenone is commonly listed as having acute toxicity via the oral route, which means ingestion can cause harmful effects, so describing it as harmful if swallowed aligns with standard hazard communication.
- The reasoning behind this classification is that ingestion can lead to systemic effects or local irritation, and the SDS typically flags this as an oral toxicity hazard to inform precautions like not eating or drinking in the work area and using appropriate PPE to prevent ingestion.
- Therefore, labeling acetophenone as "Harmful if swallowed" reflects a correct interpretation of its acute oral toxicity hazard.

Analysis of Option B — Causes serious eye irritation:
- The phrase “causes serious eye irritation” corresponds to hazard statement H319 in many systems, which is used for substances that cause serious eye irritation with potential for significant conjunctival irritation or discomfort. It is a distinct category from H314 ( Causes skin irritation ) or H318 ( Causes serious eye damage ), depending on the severity described in the SDS.
- In many acetophenone SDS entries, eye-related hazards are noted, and some entries specifically state eye irritation or serious eye irritation. If the SDS lists acetophenone as causing serious eye irritation, then Option B would be correct.
- The key distinction here is whether the SDS uses H319 (serious eye irritation) or H318 (eye damage). The statement in Option B matches the common phrasing for H319 and would be considered true when the SDS explicitly lists that level of eye hazard.

Contextual note on accuracy:
- Since the question requests hazard codes from SigmaAldrich’s SDS, you should verify the exact wording and codes (for example, H302 vs H319) in the current product safety data sheet for the specific acetophenone grade you are using, as there can be slight variations by supplier or formulation.
- If the SDS lists H319 (Causes serious eye irritation), then Option B is correct as stated. If instead it lists H318 (Causes serious eye damage), the wording would not match, and Option B would be inaccurate. Always cross-check the exact hazard statements on the SDS in use.

Summary:
- Option A (Harmful if swallowed) aligns with the general acute oral toxicity hazard and is typically correct if the SDS lists H302 for acetophenone.
- Option B (Causes serious eye irritation) can be correct if the SDS specifies H319; verify the exact eye hazard note on the SDS you consult.
- In absence of the actual SDS text here, both statements reflect common hazard descriptions found for acetophenone, but the definitive confirmation depends on the current SigmaAldrich SDS wording you access. Ensure you reference the specific hazard statements (H-codes) shown in that document to confirm.
