Lab safety and SDS
Thu, Sep 3, 2026 · Week 2 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Identify core lab safety rules, PPE, and how to read a Safety Data Sheet before completing the PLTW intro task.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Chemical: Hydrogen peroxide, 3 percent solution
Hazard class (Section 2): Mild eye and skin irritant; oxidizer
Required PPE (Section 8): Splash goggles and nitrile gloves
First aid (Section 4): For eye contact, rinse with water for at least 15 minutes and seek help if irritation continues. For skin contact, wash with soap and water.
Disposal (Section 13): Dilute with water and flush down the drain only if local rules allow, otherwise collect in the labeled waste container.
Note: I found hazards in Section 2 and first aid in Section 4, exactly where the SDS standard puts them.
| SDS Section | What it tells you |
|---|---|
| Section 2 | Hazard identification |
| Section 4 | First-aid measures |
| Section 8 | Exposure controls and PPE |
| Section 13 | Disposal considerations |
This model shows the level of evidence and organization needed to complete: A reference card that records the key safety information a student pulls from a Safety Data Sheet for one assigned chemical, used to complete the launch safety task.
- Define the term in plain scientific language.
- Connect it to the current investigation.
- Use it accurately in a new example or contrast.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Hand in your completed SDS card at the end of class. Also complete the online lab-safety contract task.
Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Locating hazard and first-aid information in the standard SDS sections.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
