WARNING
TM 5-6630-215-12
(a) Public Health Service drinking water standards call for
not more than 250 mg/l of sulfate because of its cathartic action.
The taste threshold of magnesium sulfate is 400 to 600 mg/l and for
calcium sulfate is 250 to 800 mg/l.
Sulfate may be either beneficial
or detrimental in water used for manufacturing the domestic supply.
In domestic water systems, sulfates do not appear to cause any
increased corrosion on brass fittings but - concentrations above 200
mg/l do increase the amount of lead dissolved from lead pipes.
(b) This kit provides a quantitative method for determining
the concentration of sulfate in water.
When used in reconnaissance of
raw water sources, a determination can be made as to the type of pro-
cess required; i.e., coagulation, or distillation.
As sulfate concen-
tration approaches 3000 mg/l and calcium hardness exceeds 250 mg/l,
(para 2-22g) a scale insoluble in citric acid will form in the
tubes of distillation unit.
Keep all containers tightly capped.
Do not allow
reagent chemicals to come in contact with skin or
eyes.
Do not ingest.
Most chemical reagents
are either corrosive or poisonous or both.
Hydrochloric Acid.
For test purposes only.
Keep
away from children.
May cause severe burns -
avoid breathing vapors.
Not for internal use.
In case of contact with skin or eyes, flush well
with water, for eyes get medical attention. If
swallowed call a physician at once.
Do not
induce vomiting.
Give milk of magnesia with
large amounts of water.
Follow with milk or raw
egg whites beaten in water.
Isopropyl Alcohol.
For test purposes only.
Flammable.
Keep away from sparks or open flame.
Not for internal use.
Contains toxic material.
Symptoms, vomiting, abdominal pain, depressed
respiration.
Antidote:
if swallowed, call a
physician at once, induce vomiting by giving a
tablespoonful of salt in a glass of warm water,
repeating
until vomit is clear.
Phenolphthalein
Indicator.
Keep out of reach of
children.
For test purposes only.
Flammable.
Keep away from sparks or open flame.
Not for
internal use, contains toxic material. If
swallowed,
call a physician at once.
Induce
vomiting by giving a tablespoon of salt in a
glass of warm water, repeating until vomit is
clear.
