- Evaluate laboratory infrastructure requirements based on the thermodynamic and physical properties of reagents.
- Interpret Safety Data Sheets and GHS pictograms to mitigate acute and chronic exposure risks.
All 10 Questions
- When neutralizing a concentrated sulfuric acid spill on a stone benchtop, which protocol demonstrates the highest level of risk mitigation?A) Rapidly pouring concentrated sodium hydroxide directly onto the spill site.B) Encircling the spill with an inert absorbent before adding sodium bicarbonate slowly.C) Wiping the area immediately with paper towels to prevent surface etching.D) Diluting the acid with a high-volume water spray before using a floor drain.
- Nitric acid may be safely stored in the same secondary containment tray as glacial acetic acid, provided both are labeled as 'Acids'.A) TrueB) False
- A student is synthesizing an organometallic compound that is highly pyrophoric. The most critical safety infrastructure required for this procedure is a/an ____.A) Standard vertical sash fume hoodB) Inert atmosphere glove boxC) Biological safety cabinet (Class II)D) Recirculating ductless workstation
