This is level 1 – try again. Move through the scene and try to identify as many health and safety hazards, or examples of poor practice, as you can. Look for the key within the scene and this will allow you to progress to the next level (see right). More guidance on each level further below.
General guidance on the levels: Each level is slightly different with decreasing levels of guidance as you progress. All levels offer points for discussion between learners.
Level 1: You will see 3 or 4 images within the scene without any hints. As you progress, you will see the same images containing blue numbered dots to highlight the areas with health and safety issues. The blue numbered dots correspond to the hint button below.
Level 2: Same as level 1 except the blue dots do not contain any numbers and there is no additional hints.
Level 3: The scene presented offers no specific hints except to indicate the extent of health and safety issues.
1. Keep the sash down when the fume hood is not in use.
2. All flasks and beakers should be labelled.
3. Is a beaker the best option here? Particularly if heating? Should it clamped?
4. Spilled chemicals should be immediately cleaned up.
5. Food or drink should not be consumed within a lab.
6. There should never be open bottles of chemicals on the bench, especially when they are a serious health hazard (see the CLP hazard pictograms).
7. Flask should be labelled. If the chemicals inside are hazardous it should be kept in the fume hood.
8. TLC plates should not be cut up outside of the fume hood as silica dust can be hazardous if inhaled. If completing TLC on the bench, there must be a consideration of eluent hazards.
Additional activity: Can you spot any additional synthetic chemistry lab health and safety issues that have not been highlighted?
Disclaimer: We have deliberately introduced health and safety issues into these synthetic chemistry lab scenes for educational purposes. We do not condone bad lab practice, but allowing learners to see such scenarios can help develop hazard perception skills and a general appreciation of health and safety. We have not highlighted all hazards in these exercises. Best practice may differ in your institution so please discuss this with a local instructor.
