2. true or false: eye wash stations are designed to treat both eyes at the same time.
3. what should you do with your hands when using the eyewash station?
4. how long should the eye wash station be used?
5. what safety equipment should be used for a large chemical spill on your body?
6. what are the three main components of a fire?
7. true or false? solvents that are not in use should be capped and stored in the fume hood.
8. how should you extinguish a small laboratory fire?
9. how should you put out a bunsen burner fire?

10.what should you do if your clothing catches on fire?
11.what type of fire extinguisher is likely in your chemistry lab?
12.what is the cardinal rule for responding to emergencies?

Explanation:

1. Without watching the video, it's hard to say the two - focused lab emergencies. But common ones are chemical spills and fires.
2. Eye - wash stations are often designed to treat both eyes simultaneously to ensure quick and effective rinsing.
3. When using an eyewash station, you should hold your eyelids open to ensure the eyes are properly rinsed.
4. Eye - wash stations should be used for at least 15 minutes to thoroughly flush out any contaminants.
5. For a large chemical spill on the body, a safety shower should be used immediately.
6. The three main components of a fire are fuel, oxygen, and an ignition source (the fire triangle).
7. Solvents not in use should be capped and stored in a fume hood to prevent vapors from spreading and potential fire or health hazards.
8. A small laboratory fire can often be extinguished using a fire extinguisher appropriate for the type of fire (e.g., Class B for flammable liquids).
9. To put out a Bunsen burner fire, turn off the gas supply.
10. If clothing catches on fire, stop, drop, and roll to smother the flames.
11. In a chemistry lab, a Class B or Class ABC fire extinguisher is likely to be present.
12. The cardinal rule for responding to emergencies is to ensure personal safety first.
