PPE and notebook practical
Wed, Sep 2, 2026 · Week 2 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Set up a lab notebook to SOP standard and demonstrate correct PPE selection in a hands-on station rotation.
What a finished product looks like
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.
Date: 2026-08-26 Station: Measuring mass of an unknown powder
Purpose: Measure the mass of three samples of an unknown powder following the station SOP.
Materials: Digital balance, weigh boats, scoopula, unknown powder, goggles, nitrile gloves.
PPE chosen: Splash goggles and nitrile gloves, because the SDS lists the powder as a mild irritant.
SDS lookup: Hazard (Section 2) mild irritant; First aid (Section 4) rinse skin with water.
Steps: 1) Tare the balance with the weigh boat. 2) Add one scoop of powder. 3) Record mass. 4) Repeat for three trials.
Data:
- Trial 1: 2.41 g
- Trial 2: 2.38 g
- Trial 3: 2.45 g
Source of error: The balance drifted slightly between readings, so I tared before each trial. Limitation: a single balance cannot detect mass below 0.01 g.
| Trial | Mass (g) |
|---|---|
| 1 | 2.41 |
| 2 | 2.38 |
| 3 | 2.45 |
Also due today: Show your notebook page to your teacher before leaving; a photo will be uploaded to the tracker.
