Question 7 (1 point)

What are some safety precautions that you will need to make sure you are aware in this lab?

Question 7 options:

	You will be working with organic solvents and solids. These solvents are highly flammable. Keep solvents away from very high heat.
	Naphthalene and iodine give off very strong vapors – work under the hood or snorkels with these solids.
	You will be working with organic solvents and solids. These solvents are should be kept by the sink at all times.
	CAREFULLY dispose of all solutions and remaining solids in the waste container labeled Hexanes and acetone.    Use small aliquots of water from a rinse bottle to clear the test tubes if needed; this waste also goes into the waste container.  Make sure to wipe down your work space and return all other cleaned glassware to the correct locations within your drawers.  Do not leave drying glassware by the sinks.
	CAREFULLY dispose of all solutions and remaining solids in the waste container labeled non-hazardous waste.    Use small aliquots of water from a rinse bottle to clear the test tubes if needed; this waste also goes into the waste container.  Make sure to wipe down your work space and return all other cleaned glassware to the correct locations within your drawers.  Do not leave drying glassware by the sinks.
	CAREFULLY dispose of all solutions and remaining solids down the sink with lots of water.    Use small aliquots of water from a rinse bottle to clear the test tubes if needed; this waste also goes into the waste container.  Make sure to wipe down your work space and return all other cleaned glassware to the correct locations within your drawers.  Do not leave drying glassware by the sinks.
