The NFPA (National Fire Protection Agency) has established a
|\ |\ |\ |\ |\ |\ |\ |\ |\
coded system of labeling that enables firefighters to identify the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
hazards of a substance or area quickly. This consists of 4 small,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
blank, color-coded diamonds on 1 label. The left blue diamond
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
signifies:
a. flammability
|\
b. health
|\
c. reactivity
|\
d. properties and categories not explained by other sections
|\ |\ |\ |\ |\ |\ |\ |\
b
(The rating system within each section of the NFPA is numbered
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
0-4, ranging from the least serious to extremely dangerous. In
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
general a rating of 0 = no hazard, 1 = slight hazard, 2 =
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
moderate hazard, 3 = severe hazard, and 4 = extreme hazard.)

Which of these is recommended for use in the tissue processor
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
for demonstration of small biopsies?
|\ |\ |\ |\
a. eosin
|\
b. methylene blue
|\ |\
c. hematoxylin
|\
d. picric acid
|\ |\
b
(Eosin is NOT recommended for use in the tissue processor due
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
to the dye's fluorescent capability.)
|\ |\ |\ |\
Which of these should be used for solution preparation?
|\ |\ |\ |\ |\ |\ |\ |\
, a. volumetric glassware
|\ |\
b. Erlenmeyer flasks
|\ |\
c. beakers
|\
d. all of the above
|\ |\ |\ |\
a
(Volumetric glassware is used for accurately dispensing variable|\ |\ |\ |\ |\ |\ |\ |\
volumes of liquids or solutions. Calibrated Erlenmeyer flasks or
|\ |\ |\ |\ |\ |\ |\ |\ |\
beakers are too inaccurate.) |\ |\ |\
T/F: Strongly alkaline solutions should NOT be stored in glass.
|\ |\ |\ |\ |\ |\ |\ |\ |\
T
(These concentrated alkalis will react with the acidic oxide that is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
glass and dissolve the glass from the inside wall.)

A method of compensating for variances in the actual dye
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
content of dry dyes used in preparation of staining solutions.
|\ |\ |\ |\ |\ |\ |\ |\ |\
a. molarity
|\
b. normality
|\
c. gravimetric factor
|\ |\
d. none of the above
|\ |\ |\ |\
c
(Formula for gravimetric factor: |\ |\ |\
Concentration of present dye / Concentration of new dye = |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Gravimetric factor) |\
