Ever wonder how to justify the time it takes to do hazard and risk assessment on your work? The American Chemical Society just posted this short video discussing the why of hazard and risk assessment (and what the difference is between them).
Have a look at the video–and learn how crossing the street relates to lab experimentation.
Hazard assessment is an important part of the overall process of controlling hazards in the laboratory. The American Chemical Society recently developed a website that gives detailed information and tools for doing hazard assessments–tools that apply not only to chemistry but to all laboratory research.
I encourage all researchers to look at the ACS’s site to see what lessons can be learned. If you would like an introduction to the resources available or a “teach-in” on a particular part (e.g., standard operating procedures–what we call “experimental protocols” in academia), please contact me at email@example.com.
The safety posters below may be used by any JHU laboratory–just print them out and post!
Be sure to choose a poster suitable for your lab. A poster about lab coats is not appropriate in a mechanical lab where lab coats are forbidden (because they might catch on something). A poster about compressed gases might be a better choice in that case.
Rotate safety posters at least quarterly. Research shows that posters start to lose effectiveness quickly, so “switching them up” is a good way to keep your fellow researchers safety-aware.
Do you dispose of different types of chemicals? If so, you run the risk of mixing incompatible chemicals together in your waste containers. Refer to this chart (EPAChemicalCompatibilityChart) to help determine what you can put in the same waste container. The chart is fairly complex, but the topic is also fairly complex. Always be sure to use secondary references such as Safety Data Sheets to verify that your chemicals are compatible–the EPA chart is general, not specific.
