ASCP Histology Exam questions with
|\ |\ |\ |\ |\
answers
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.)
