Material20033 3. HAZARD SYMBOLS!2003 4 4. 1 of 22003 5 5. 2 of 2
Compressed Gas(Class A):Poses an explosion dangerbecause the gas is
under pressureContainer may explode if heated ina fire, or dropped
20036 6. 1 of 22003 7 7. 2 of 2 Combustible and Flammable
Materi(Class B):Will burn and is therefore a potential fire
hazardMay burn at relatively low temperatures;flammable materials
catch fire at lowertemperatures than combustible materialsMay burst
into flame spontaneously in air, orrelease a flammable gas on
contact with waterMay cause a fire when exposed toheat, sparks, or
flames, or as a result of friction20038 8. 1 of 22003 9 9. 2 of 2
Oxidizing Material (Class C):Poses a fire and/or explosion risk in
thepresence of flammable or combustiblematerialMay react violently
when it comes intocontact with combustible materials such asfuels
or woodMay burn skin and eyes upon contact 2003 10. 1 of 22003 11.
2 of 2 Poisonous and Infectious Material (Class D, Division 1):Is a
potentially fatal poisonous substanceMay be fatal or cause
permanent damageif it is inhaled or swallowed or if it enters
thebody through skin contactMay burn eyes or skin upon contact 2003
12. 1 of 22003 13. 2 of 2 Poisonous and Infectious Material: Other
Toxic Effects (Class D, Division 2):Not immediately dangerous to
healthMay cause death or permanent damage as aresult of repeated
exposure over timeMay be a sensitizer, which produces anallergyMay
cause cancer, birth defects, or sterility2003 14. 1 of 22003 15. 2
of 2 Poisonous and Infectious Material: Biohazardous, infectious
material(Class D, Division 3):May cause a serious diseaseresulting
in illness (AIDS, Hepatitis)or deathCan also include
tetanusprotection2003 16. 1 of 22003 17. 2 of 2 Corrosive Material
(Class E):Causes severe eye and skinirritation upon contactCauses
severe tissue damagewith prolonged contactOften produces vapor or
fumesthat may be harmful if inhaled2003 18. 1 of 22003 19. 2 of
2Dangerously Reactive Material (Class F):Is very unstableMay react
with water to release a toxicor flammable gasMay explode as a
result ofshock, friction or an increase intemperatureMay explode if
heated when in a closedcontainer2003 20. DANGER 21. WARNING 22.
CAUTION 23. A pure substance is a material whose properties are not
a blend and are always the same Ex. Gold, SilverApure substance
must be HOMOGENEOUS 24. Allpure substances are homogeneous, but all
homogeneous mixtures are not pure substances There are two types of
materials; Homogeneous Heterogeneous 25. Homogeneous Mixture that
looks like it is one material Coke Cola, Milk Heterogeneous when
the parts are visibly different Chocolate Chip Cookie 26. A mixture
that looks like one material butis very difficult to separate
Ketchup, Milk 27. is a heterogeneous fluid containing solid
particles 28. The solubility of a substance is the amount of that
substance that will dissolve in a given amount of solvent Has two
parts; Solute -- What is being dissolved Solvent The dissolving
substance 29. Thepoint where no more solute can be dissolved into a
given solvent at room temperature Super-Saturation When more solute
is dissolved in a solvent than normal 30. Temperature When the
temp. goes up in a liquid so does thesolubility When temp goes up
in a gas, the solubility goesdown 31. ACRONYMNto remember itS
Spaces between particles P Particles all matter is made of it A
Attraction attracted or bonded to each other M Movement of
particles (alwaysmoving) 32. Thehigher the viscosity the thicker
the substance is Thelower the viscosity the thinner the substance
is 33. Liquidcannot be as compressed as much as gas because the
spaces between the particles are not as far apart. 34. Dividethe
amount of your solute into your amount of solvent Ex.13g of salt is
dissolved into 50ml of water 13g/50ml 35. TOsolve for density you
must use the following equation; Density = mass/volume 36. When in
a liquid, the force of gravity pulls itdown, The liquid releases an
opposite force to gravity called BUOYANT FORCE, pushing the object
upwards Ifthe liquid the object is in is more densethe buoyant
force is greater than gravityand the object floats 37. Means high
pressure 38. KNOW ALL OF THE ORGAN SYSTEMS Digestive Respiratory
