Inhalation:
Electrolyte: Breathing of sulfuric acid vapors or mists may cause severe
respiratory irritation.
Lead compounds: Inhalation of lead dust or fumes may cause irritation of upper
respiratory tract and lungs.
Ingestion:
Electrolyte: May cause severe irritation of mouth, throat, esophagus, and stomach.

Medical Conditions Generally
Aggravated by Exposure:
Overexposure to sulfuric acid mist may cause lung damage and aggravate pulmonary conditions. Contact of
electrolyte (water and sulfuric acid solution) with skin may aggravate skin diseases such as eczema and
contact dermatitis. Contact of electrolyte (water and sulfuric acid solution) with eyes may damage cornea
and/or cause blindness. Lead and its compounds can aggravate some forms of kidney, liver, and neurologic
diseases.
