the _________ of embalming fluid refers to the length of time the fluid
maintains its functionality before it is used.
Ans: Shelf Life
what are 4 factors that affect the shelf life of embalming chemicals?
Ans: Temperature, Time, pH, Light
________ temperatures accelerate polymerization of formaldehyde
into paraformaldehyde, a solid that precipitates out of the solution.
This has an overall effect of reducing the index of the remaining fluid.
Ans: Elevated
elevated temperatures cause ________ of other disinfectant and
preservative components in the fluid.

Ans: Depressed
the average shelf life for embalming chemicals is ___-___ years.
Ans: 2, 5
this will cause polymerization of many of the components of
embalming fluid especially formaldehyde.
Ans: Time
on average you shouldn't keep more than a ____ month supply of
embalming fluid on hand.
Ans: 6
this is routinely used as an antipolymerizing agent for formaldehyde.
Given enough time it can be oxidized to formaldehyde which will then
turn into paraform.
Ans: Methanol
this refers to the acidity or alkalinity of the solution.
Ans: pH

Ans: Buffers
some dyes maybe _______ when exposed to light which causes a color
change of the fluid.
Ans: Oxidized
some dyes maybe oxidized when exposed to ________ which causes a
color change of the fluid.
Ans: Light
_______ can also increase polymerization of formaldehyde.
Ans: Light
______ fluid is the concentrated, preservative embalming chemical
that will be diluted with water or another appropriate vehicle such as
