While preparing solutions for your experiment you accidentally drop a glass flask with solvent. Select the appropriate course of action from the following options (more than one option may be correct):

Question

BlackTom AI · Accepted Answer

Solvent spills require immediate area control, communication, and a trained response because they can create inhalation, fire, slipping, and broken-glass hazards.

1. Relevant knowledge points and concepts
- Chemical safety hierarchy: remove people from harm, isolate the hazard, then engage trained responders.
- Solvent hazards: many solvents are volatile (inhalation risk), flammable, and can spread on surfaces.
- Glass breakage hazards: broken glass can cut and contaminate cleanup materials.
- Appropriate cleanup requires PPE, a chemical spill kit, and knowledge from the Safety Data Sheet (SDS).

2. Step-by-step reasoning
- First priority is human safety: prevent others from entering the area (reduce exposure).
- Next, alert responsible personnel (teaching staff/lab tech) who are trained, have access to spill kits, PPE, and knowledge of the specific solvent/SDS.
- Do not personally attempt an ad-hoc cleanup (e.g., paper towels) unless you are trained and have appropriate PPE and spill absorbents; improper cleanup can spread the solvent or cause a fire or injury from glass.

3. Calculations
- None required for this scenario.

4. Why the correct answers are correct
- b (Notify other students and avoid the area): Correct because you must prevent additional people from being exposed and avoid contaminating more of the lab.
- c (Immediately inform teaching/lab tech staff): Correct because trained staff will assess the chemical, consult the SDS, use the right PPE and cleanup materials, and manage disposal.

5. Why the other option is incorrect
- a (Take paper towels and mop up the spill): Incorrect because paper towels are not a proper spill control method for solvents, can spread contamination, may catch fire if the solvent is flammable, and expose you to broken glass and vapors. Only trained personnel using a spill kit should clean up.

6. Conclusion
The appropriate actions are b and c, which matches the provided correct answers.
