SECTION 6: HEALTH HAZARD DATA
Battery is considered as sealed non-spillable one. Under normal operating conditions, the materials sealed inside should not be
hazardous to people’s health. Only when these materials exposed during production or under case broken condition or being
extremely heated (fired), they may be hazardous to people’s health.
Routes of Entry:
Sulfuric Acid: Harmful by all routes of entry.
Lead Compounds:
Hazardous Exposure can occur only when product is heated, oxidized, or otherwise processed or damaged
to create dust, vapor or fume.
Inhalation:
Sulfuric Acid:
Breathing sulfuric acid vapors and mists may cause severe respiratory problems.
Lead Compounds:
Dust or fumes may cause irritation of upper respiratory tract or lungs.
Skin Contact:
Sulfuric Acid:
Severe irritation, burns and ulceration.
Lead Compounds:
Not absorbed through the skin.
Ingestion:
Sulfuric Acid:
May cause severe irritation of the mouth, throat, esophagus, and stomach.
Lead Compounds:
May cause abdominal pain, nausea, vomiting, diarrhea, and severe cramping. Acute ingestion should be
treated by a physician.
Acute Health Hazards:
Sulfuric Acid:
Severe skin irritation, burns, damage to cornea may cause blindness, upper respiratory irritation.
Lead Compounds:
May cause abdominal pain, nausea, headaches, vomiting, loss of appetite, severe cramping, muscular aches
and weakness, and difficulty sleeping. The toxic effects of lead are cumulative and slow to appear. It affects the kidneys,
reproductive and central nervous systems. The symptoms of lead overexposure are listed above. Exposure to lead from a
battery most often occurs during lead reclamation operations through the breathing or ingestion of lead dust or fumes.
Chronic Health Hazards:
Sulfuric acid:
Possible scarring of the cornea, inflammation of the nose, throat and bronchial tubes, possible erosion of tooth
enamel.
Lead Compounds: May cause anemia, damage to kidneys and nervous system, and damage to reproductive system in both
males and females.
Medical Conditions Generally Aggravated by Exposure
Inorganic lead and its compounds can aggravate chronic forms of kidney, liver, and neurological diseases. Contact of battery
electrolyte (acid) with the skin may aggravate skin diseases such as eczema and contact dermatitis. Overexposure to sulfuric
acid mist may case lung damage and aggravate pulmonary conditions.
