Chemistry Lab Safety Practice Test

Damaged glassware is a safety risk because cracks and chips create hidden weaknesses that can fail suddenly during use, heating, or handling, leading to cuts, spills, or exposure to hazardous materials. Attempting to patch or repair it isn’t reliable—adhesives and tape can fail under solvents or heat and do not restore structural integrity or a leak-proof seal. Reusing damaged glassware increases the chance of injury and contamination, even if the damage seems minor. The correct practice is to discard damaged glassware in the designated glass waste container and replace it as needed, after inspecting equipment for integrity before use.
