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. The prescence of nascent
hydrogen may generate highly toxic arsine gas.
Inhalation: Sulfuric Acid: 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: Sulfuric Acid: May cause severe irritation of mouth, throat, esophagus and stomach. Lead Compounds: Acute
ingestion may cause abdominal pain, nausea, vomiting, diarrhea and severe cramping. This may lead rapidly to systemic
toxicity and must be treated by a physician.
Skin Contact: Sulfuric Acid : Severe irritation, burns and ulceration. Lead Compounds: Not absorbed through the skin.
Arsenic Compounds: Contact may cause dermatitis and skin hyperpigmentation.
Eye Contact: Sulfuric Acid: Severe irritation, burns, cornea damage, and blindness.
Lead Compounds: May cause eye irritation.
Effects of Overexposure Acute: Sulfuric Acid : Severe skin irritation, damage to cornea, upper respiratory irritation. Lead
Compounds: Symptoms of toxicity include headache, fatigue, abdominal pain, loss of appetite, muscular aches and
weakness, sleep disturbances and irritability.
Effects of Overexposure – Chronic: Sulfuric Acid : Possible erosion of tooth enamel, inflammation of nose, throat &
bronchial tubes. Lead Compounds: Anemia; neuropathy, particularly of the motor nerves, with wrist drop; kidney damage;
reproductive changes in males and females. Repeated exposure to lead and lead compounds in the workplace may result in
nervous system toxicity. Some toxicologists report abnormal conduction velocities in persons with blood lead levels of
50µg/100 ml or higher. Heavy lead exposure may result in central nervous system damage, encephalopathy and damage to
the blood-forming (hematopoietic) tissues.
Carcinogenicity: Sulfuric Acid : The International Agency for Research on Cancer (IARC) has classified “strong inorganic
acid mist containing sulfuric acid” as a Category I carcinogen, a substance that is carcinogenic to humans. This classification
does not apply to liquid forms of sulfuric acid or sulfuric acid solutions contained within a battery. Inorganic acid mist (sulfuric
acid mist) is not generated under normal use of this product. Misuse of the product, such as overcharginging, may result in
the generation of sulfuric acid mist. Lead Compounds: Lead is listed as a 2B carcinogen, likely in animals at extreme doses.
Proof of carcinogenicity in humans is lacking at present. Arsenic: Listed by National Toxicology Program (NTP), International
Agency for Research on Cancer (IARC), OSHA and NIOSH as a carcinogen only after prolonged exposure at high levels.
Medical Conditions Generally Aggravated by Exposure: Overexposure to sulfuric acid mist may cause lung damage and
aggravate pulmonary conditions. Contact of sulfuric acid with skin may aggravate diseases such as eczema and contact
dermatitis. Lead and its compounds can aggravate some forms of kidney, liver and neurologic diseases.
Additional Health Data:
All heavy metals, including the hazardous ingredients in this product, are taken into the body primarily by inhalation and
ingestion. Most inhalation problems can be avoided by adequate precautions such as ventilation and respiratory protection
covered in Section 8. Follow good personal hygiene to avoid inhalation and ingestion: wash hands, face, neck and arms
thoroughly before eating, smoking or leaving the work site. Keep contaminated clothing out of non-contaminated areas, or
wear cover clothing when in such areas. Restrict the use and presence of food, tobacco and cosmetics to non-contaminated
areas. Work clothes and work equipment used in contaminated areas must remain in designated areas and never taken
home or laundered with personal non-contaminated clothing. This product is intended for industrial use only and should be
isolated from children and their environment.
The 19
th
Ammendment to EC Directive 67/548/EEC classified lead compounds, but not lead in metal form, as possibly toxic to
reproduction. Risk phrase 61: May cause harm to the unborn child, applies to lead compounds, especially soluble forms.
