Lab safety and SDS
Identify core lab safety rules, PPE, and how to read a Safety Data Sheet before completing the PLTW intro task.
SDS lookup card: for one assigned chemical, record the name, hazard class (Section 2), required PPE (Section 8), first-aid steps (Section 4), and disposal method (Section 13).

💡 Big idea: Proper PPE and SDS literacy are non-negotiable prerequisites before anyone enters a biomedical lab.
- 0:00Overview: why handling, preparation, storage, and disposal is one of the largest parts of the WebXam; real consequences of PPE failure
- 0:10Teacher-led notes: four PPE categories, when each is required, and how to select glove type
- 0:25SDS walkthrough: navigate all 16 sections; students highlight Sections 2, 4, 6, 8, and 13 (disposal)
- 0:45Chemical pictogram matching activity: match three chemicals to GHS hazard pictograms
- 0:55myPLTW: open lab-safety contract task, read, and complete online signature
- 1:10Exit: write one independent variable and one control for a future experiment; collect contracts
- • Before we touch anything in this lab all year, we have to talk about safety. Not as a formality, but because in biomedical science, a mistake with chemicals or a specimen can genuinely harm you.
- • OSHA, the Occupational Safety and Health Administration, requires anyone working with hazardous chemicals to have access to a Safety Data Sheet. We will learn to read one today.
- • Every chemical in this lab has an SDS. The SDS tells you exactly what protective equipment to wear, what to do if you spill it, and how to dispose of it properly.
- • By the end of today you will sign your lab safety contract, which means you are making a commitment to your own safety and your partners'.
- 1Take teacher notes on the four PPE categories and when each is required.
- 2Walk through the 16 sections of an SDS and find the hazard and first-aid sections.
- 3Match three common lab chemicals to their hazard pictograms.
- 4Open the PLTW launch lesson and complete the lab-safety contract task online.
- 5Write one independent variable and one control you will track in any experiment.
- • I can name the PPE required for a given hazard.
- • I can locate hazard and first-aid info on an SDS.
- • The four PPE categories are eye/face protection, gloves, protective clothing, and respiratory protection.
- • An SDS has 16 standard sections; hazard identification is Section 2, first aid is Section 4.
- • Controlled variables are kept constant so that only the independent variable causes changes in results.
