What does SDS stand for? What type of information is typically contained in an SDS?
Safety Data Sheet, chemical hazards, hazard class, shipping/transportation information, incompatibilities, composition, medical countermeasures, etc.
300
What is the flashpoint of a liquid? What does it mean if something has a low flash point?
The lowest temperature at which liquid produces enough vapor to support combustion. Low flashpoint is a serious fire hazard - remains flammable at low temperatures
300
List one corrosive chemical we have in the lab and what to do if you spill it on yourself
lye (NaOH/sodium hydroxide), muriatic, sulfuric, wash with copious amounts of water
300
List 3 common HME fuels
acetone, sugar, diesel, aluminum, nitromethane, etc.
300
How many protons, neutrons, and electrons does oxygen have?
protons/electrons: 8
neutrons: 8
300
What is the depth of compressions for CPR for an adult?
1.5-2"
400
Define volatility
How readily a liquid vaporizes (evaporates)
400
List 3 flammable liquids we have in the lab
acetone, alcohols, ethers, etc.
400
List one water-reactive chemical
WP, alkali metals (lithium, sodium, K,etc.), DC, DF, SOCl2, PCl3, PCl5, metal hydrides (sodium borohydride, lithium aluminum hydride), etc.
400
Which column of the periodic table is the "Noble gases,"? What does this mean?
The furthest column to the right; they are unreactive and don't like to form bonds with anything. They don't 'associate' with the commoners (other elements)
400
What does this placard mean? What hazard class is this?
oxidizer
500
Define LD50 and LCt50. Do these numbers depend on route of exposure?
measures of a substances acute or short-term toxicity
LD50: dose (liquids or solids in mg/kg) which when administered within a certain time period, results in death of 50% of the test population
LCt50: concentration (gases in mg/m3)
500
List something acids react with to produce toxic or flammable gases (i.e. we don't want this in the acidic waste drum)? There are several answers
cyanides, sulfides, phosphides, metals, etc.

500
If a chemical is described as 'halogenated' or having a 'halogen,' list one element it might include. Are halogens typically hazardous?
fluorine, chlorine, bromine, iodide
Yes, they are typically hazardous. They are often carcinogenic, toxic, and persistent. They also react with common chemicals such as acids to produce toxic gases
