Minimizing Risks in Chemistry Laboratory Practices

This video focuses on lab safety techniques, emphasizing the RAMP process: Recognize hazards, Assess risks, Minimize risks, and Prepare for emergencies. It covers the importance of personal protective equipment (PPE), organizing lab spaces, safe titration and chemical synthesis practices, and proper waste management. The video concludes with a reminder to always be mindful of safety and to follow RAMP guidelines.

What does RAMP stand for in lab safety?

• Recognize, Avoid, Manage, Prepare

• Recognize, Assess, Manage, Prevent

• Recognize, Avoid, Minimize, Prevent

• Recognize, Assess, Minimize, Prepare

Why is it important to keep your workspace clean and organized?

• To impress your instructor

• To minimize the risk of trips, spills, or using the wrong reagent

• To avoid getting a bad grade

• To make it easier to find your equipment

What should you do with unused chemicals during an experiment?

• Mix them with other chemicals

• Leave them on the bench

• Dispose of them immediately

• Store them in a labeled container

What is a safe way to handle a pipette?

• Use it to stir the solution

• Place it directly into the stock solution

• Grasp it close to the end and gently insert it into the bulb

• Insert it forcefully into the bulb

Why should you label beakers and flasks temporarily during titrations?

• To avoid confusion and prevent mixing the wrong chemicals

• To make them look professional

• To keep track of the experiment's progress

• To ensure they are clean

What should you do if you spill a solid at the balance?

• Clean it up immediately and put the spilled solid into a waste container

• Leave it for the next person to clean

• Mix it with other solids

• Ignore it and continue weighing

How should you handle hot glassware in the lab?

• With bare hands

• By blowing on it to cool it down

• With beaker tongs or crucible tongs

• With a paper towel

What should you do with leftover solids, solvents, or solutions at the end of an experiment?

• Pour them down the sink

• Leave them on the bench

• Mix them together

• Share them with lab mates or dispose of them in the proper waste container

Why is it important to close the waste container after adding your solution?

• To prevent evaporation

• To save space

• To keep the lab clean

• To avoid mixing incompatible chemicals

What should you always do after removing disposable gloves?

• Throw them on the floor

• Put them in your pocket

• Reuse them

• Wash your hands
