	using flammable liquids until all containers and surfaces are cool to the touch.		- Mention of a fume hood is a moot point, since we don't have one and we likely will never use one while presenting at a school.
	* Any volunteers must also wear approved safety gear (goggles/gloves/coat if needed)		- Talking in regards to flammability is redundant. instead summarize it as "if the substance is flammable, please see the Fire Safety section of the Demonstration Safety page".
	* If a minor wet chemical spilled:		- The points above could be used as a starting point for talking about the different types of liquid chemicals. When doing so, be sure to define the categories, and any specific terms that new volunteers/officers might not be familiar with. Be sure to cover safety topics when it comes to the following categories:
	** Protect yourself and alert others		1. Volatile Chemicals: Chemicals with high volatility, and are often flammable as well (Methyl/Ethyl/Isopropyl alcohols, Acetone, etc.)
	** Contain spill and secure the area		2. Reactive Chemicals: chemical solutions that are highly reactive. This would include catalytic, acid and base solutions (Sodium Hydroxide solutions, Sulfuric Acid solutions, Hydrogen Peroxide 30%, etc.)
	** clean up the spill using a chemical spill kit or vermiculite		3. Inert Chemicals: solutions that are non-reactive and pose no sort of threat to the audience (Baking soda & vinegar, Sodium Acetate AKA "Hot Ice", Oobleck, etc.) -->
	** Place spill material in compatible container and label it		* Any volunteers must also wear approved safety gear (goggles/gloves/coat if needed) <!-- I feel that this point should be listed at the top with all the other safety gear points. -->
	* If a major wet chemical spilled:		<!-- "* If a minor wet chemical spilled:"
			"** Protect yourself and alert others"
			"** Contain spill and secure the area"
			"** clean up the spill using a chemical spill kit or vermiculite"
			"** Place spill material in compatible container and label it"
			- Keep in mind while writing these steps that they will be read by students who are not familiar with basic Chemistry. using phrasing as "protect yourself and alert others" could scare new recruits, and can leave some students feeling overly concerned about experiments that are perfectly safe for them to present.
			- You may want to write a few different sets of spill cleanup steps for different categories of liquid chemicals.
			-- Volatile chemicals (acetone, various alcohols) are handled differently from reactive solutions (diluted sodium hydroxide, diluted sulfuric acid, hydrogen peroxide, etc.), which are handled differently from inert solutions (oobleck, sodium acetate AKA "Hot Ice").
			-- Volatile chemicals need to be absorbed quickly to minimize fire risk (if applicable) and vaporization, so for a small spill you can use a paper towel and a large spill can use a spill agent such as vermiculite or baking soda.
			-- A reactive solution may need to be neutralized, so a spill agent such as baking soda would work efficiently for a spilled acid, but not for a spilled base. Also, depending on the concentration, the presenter may need to wear rubber/latex gloves while cleaning up a reactive solution. Lastly, a presenter would NOT want to use paper towels for a spilled reactive solution if it is concentrated; concentrated strong acids can cause paper to ignite, and the concentrated hydrogen preoxide we use will cause it to turn black and deteriorate in your hand. the spilled solutions would need to be diluted or neutralized before attempting to wipe it up.
			-- Inert solutions don't usually need a spill agent, and might actually need to have water added to dilute them and help clean up. not only that, but inert solutions don't pose a risk to anyone, so it shouldn't be necessary to "protect yourself and alert others" or "contain the spill and secure the area" for spilled Oobleck.
			- For these steps, you need to list them simply. An example list of steps is:
			Volatile liquid chemicals: these are chemicals which readily vaporize into the air around them. some of these chemicals are flammable, and so a spilled volatile chemical can pose a fire risk.
			1. If it is a small spill (amount spilled is less than 100mL) then use paper towel or similar to quickly absorb it. Dispose of the towel in a trash bag or bin.
			2. If the amount spilled is larger than 100mL, then use the spill agent from the Safety Box to absorb it quickly. Once absorbed, scoop it with a dust pan or similar and dispose of it in a trash bag or bin.
			3. If the chemical spilled was a flammable chemical, please follow the appropriate guidelines listed in the Fire Demonstration section of the Safety page.-->

			<!-- * If a major wet chemical spilled:
	** Get everyone out of the environment		** Get everyone out of the environment
	** contact ORCBS as soon as possible at (517) 355-0153 or www.orcbs.msu.edu		** contact ORCBS as soon as possible at (517) 355-0153 or www.orcbs.msu.edu
			- You need to clarify what would constitute as a "Major wet chemical spill" (MWCS). Also, This does not look like the kind of issue that we will ever need to be concerned with, so I'm unsure on if it needs to be stated in here at all. This is a statement that should be included on a separate safety form for those who prepare the diluted solutions.
			- We would only follow these guidelines for a MWCS if it happened on MSU's campus. If we were at an event and it happened, we would want to make sure that 911 was called before anything else, so that they can get a local chemical containment partner to come in. In any case, I cannot conceivably think of a scenario that this would be a concern, and so it seems unnecessary to list.
			- We never bring anything to schools that would require a response to this degree. The most hazardous solution we bring to events would be the Hydrogen Peroxide solution, which can be easily neutralized on the spot if spilled by pouring a small amount of the catalyst straight into the spill, and otherwise using the spill absorbent that is in the safety box to take care of it. Although we have some strong chemicals in the planetarium, we don't bring them to schools, and they are only used to prepare diluted solutions for demonstrations. -->

			***Cryogen liquids must be kept in a cryogen approved container. Do not overfill the container. Store and use the cryogenic liquid in a well ventilated area.
			**2.How to contain a spill.
			***Liquid Cryogens will vaporize rather quickly. Make sure to block off the area around the spill to prevent people from coming in contact with the liquid nitrogen.
			**3.What to do if you spill on yourself.
			***If the spill occurs on exposed skin, remove your skin from the liquid nitrogen immediately. If the spill occurs on clothing, pull the clothing away from your skin, while it vaporizes. If the spill was severe enough to soak your clothing so you cannot create space between the cryogen soaked cloth and your skin, you should remove that article of clothing.
			**4.How to clean up a spill
			***Objects around the spill should be moved to all the cryogen to spread and vaporize more quickly. Make sure that the area is well ventilated and the cryogen liquid dos not come into contact with people or sensitive materials.
			*''SOLIDS''
