Chipped or Cracked Glassware: Safe to Use? True or False
This quiz helps you judge when chipped or cracked glassware must be taken out of service and how to handle it safely. Answer quick questions on hot vs. cold glass, cleanup, and tool care to sharpen your lab routine. For more practice, explore experiment glassware safety and a broader glass knowledge test.
Study Outcomes
- Determine Glassware Safety -
Decide when chipped or cracked glassware is okay to use versus when it must be removed from service to prevent injury or contamination.
- Distinguish Hot and Cold Glass -
Assess whether hot glass looks the same as cold glass and apply proper checking techniques to avoid burns.
- Apply Chemical Waste Protocols -
Follow correct procedures for "after completing an experiment all chemical waste should be" disposed of safely and in compliance with regulations.
- Handle Flammable Materials Safely -
Implement best practices for working with flammable substances, including storage, transfer, and ignition control.
- Execute Emergency Steps -
Recall and perform immediate actions for common lab emergencies, such as spills, fires, and injuries.
Cheat Sheet
- Inspecting Glassware Integrity -
Chipped or cracked glassware is okay to use? Absolutely not: even a tiny nick can turn into a full break under heat or pressure. Follow NIH Lab Safety Guide recommendations to inspect every piece before and after use.
- Recognizing Hot vs. Cold Glass -
Hot glass looks the same as cold glass. true false? Though it's a classic quiz twist, the correct answer is true. A common quiz question even asks "does hot glass looks the same as cold glass," so always assume it's hot and use thermal gloves or a probe (OSHA Heat Stress Guide).
- Chemical Waste Disposal Protocols -
After completing an experiment all chemical waste should be labeled, segregated by hazard class, and placed in approved waste containers - never poured down the sink. Following EPA and university disposal rules prevents contamination and regulatory violations.
- Safe Handling of Flammable Substances -
Know each substance's flash point and store flammables below that temperature in a fire cabinet. Use the mnemonic "Know Your Flash, Close the Cap" to keep vapors contained and reduce ignition risk (NFPA 45).
- Emergency Glass Breakage Response -
For broken glassware, use a brush and dustpan - never your bare hands - to collect shards. If a chemical splash occurs, flush the area at an eyewash station or safety shower for at least 15 minutes (CDC Laboratory Safety Manual).
