can be dissolved in water as a colorless solution. In the
primary batteries, potassium hydroxide is in solution. In
solution, potassium hydroxide is corrosive and may potentially
generate explosive hydrogen gas upon contact with aluminum,
tin, lead, or zinc. Density of this material in solution is
12.8 pounds per gallon.
TOXICITY TO HUMANS: Potassium hydroxide is corrosive to bodily
tissues by all routes of exposure. Contact with concentrated
solution may result in severe burns of the skin or eyes.
Breathing concentrated mists in air from a potassium hydroxide
solution may result in irritation of the upper respiratory
tract, inflammation of the lungs, and possibly pneumonitis.
EXPOSURE LIMITS:
The exposure levels are as follows:
ACGIH TLV:
2.0 mg/cu m
ACGIH STEL:
None
F.2.c. LEAD SULFATE: Lead Sulfate (PbSO4; CHRIS Code: LSF; CAS 7446-
14-2) is a constituent of secondary (lead acid) batteries.
During the operation of secondary batteries, the lead plates in
these batteries react with sulfuric acid to produce lead
sulfate as a by-product. Lead sulfate may be present in each
secondary battery and may, depending upon the condition and
structural integrity of the batteries, be present on the
exterior of the batteries.
GENERAL DESCRIPTION: Lead sulfate appears as white crystals in
solid form. It is practically insoluble in water, but is
soluble in acid.
HEALTH HAZARDS: Lead sulfate is a corrosive irritant to the
skin, eyes, and mucous membranes. It is moderately toxic by
ingestion. Ingestion of lead sulfate may result in abdominal
pain, diarrhea, constipation, loss of appetite, muscular
weakness, headache, blue line on gums, metallic taste, nausea,
and vomiting.
EXPOSURE LIMITS:
The exposure levels to lead sulfate are as
follows:
