SECTION 4: First aid measures
4.1. Description of first aid measures
4.1.1. General information
Corrosive effects on the skin and eyes may be delayed, and damage may occur without pain sensation. Speed is
essential. OBTAIN MEDICAL ATTENTION IMMEDIATELY
4.1.2. Following inhalation
If inhaled, remove the victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Do not use mouth- to- mouth method if victim ingested or inhaled the acid. Give cardiopulmonary resuscitation if there
is no pulse and no breathing. GET IMMEDIATE MEDICAL ATTENTION. Maintain observation of the patient for delayed
onset of pulmonary oedema
4.1.3. Following skin contact
In case of contact, remove contaminated clothing and immediately flush skin with plenty of water for at least 15 minutes,
repeating flushing if irritation persists. OBTAIN MEDICAL ATTENTION IMMEDIATELY. If the patient has to be
transported to a medical facility, apply compresses of cold water. Creams or ointments should not be applied. Wash
contaminated clothing separately before reuse.
4.1.4. Following eye contact
Immediately flush eyes with plenty of running water for at least 15 minutes, keeping eyelids open. SEEK MEDICAL
ASSISTANCE IMMEDIATELY
4.1.5. Following ingestion
Do not induce vomiting. If victim is conscious, rinse mouth and give large amounts of water or milk. Never attempt to
neutralize the acid with weak bases (the exothermic reaction may extend the corrosive injury). If spontaneous vomiting
occurs, keep head below hips to avoid aspiration, rinse mouth and give more water. If victim is convulsing or
unconscious, do not give anything by mouth. OBTAIN IMMEDIATE MEDICAL ATTENTION.
4.2. Most important symptoms and effects, both acute and delayed
Inhalation may cause severe irritation of the respiratory tract with sore throat and coughing. Very dangerous in case of
inhalation at high concentrations: may cause delayed lung edema.
Ingestion may cause burns of the mouth, throat, esophagus and stomach with severe pain and risk of perforation. Can
cause nausea, vomiting, diarrhoea.
Through contact with the eyes: possibility of burns with irreversible injury of the optic nerve (blindness may result)
Through contact with the skin: causes burns.
Repeated or prolonged exposure (mist) may result in eye irritation (with tearing, pain and blurred vision) and chronic
conjunctivitis. Repeated or prolonged exposure to mists may cause corrosion of teeth and skin irritation with itching,
burning, redness, swelling or rash.
Sulphuric acid is not listed as a carcinogen by OSHA, the National Toxicology program (NTP) or the International
Agency for Research on Cancer (IARC). IARC has concluded that there is sufficient evidence that occupational
exposure to strong acid mists containing sulphuric acid is carcinogenic to humans, resulting in an increased incidence
of laryngeal cancers. IARC has classified “strong acid mist containing sulphuric acid” as a known human carcinogen,
(IARC category 1). This classification applies only to sulphuric acid mists, not to sulphuric acid or sulphuric acid
solutions. Did not show teratogenic effects in animal experiments (IUCLID).
4.3. Indication of any immediate medical attention and special treatment needed
Not applicable
SECTION 5: Fire-fighting measures
5.1. Extinguishing media
5.1.1. Suitable extinguishing media
Suitable fire extinguishing media: Use dry chemical or carbon dioxide extinguishers. If only water is available, use in
the form of a fog. Use water spray to cool containers exposed to fire. Evacuate personnel to a safe area and prevent
unauthorized entry to fire area. Keep people removed and upwind of smoke and fumes.
5.1.2. Unsuitable extinguishing media
Do not use water directly on acid (a violent reaction may occur resulting in spattering of the acid).
5.2. Special hazards arising from the substance or mixture
Sulphuric acid is not flammable or combustible. However, fires may result from the heat generated by contact of
concentrated sulphuric acid with combustible materials. In the event of fire SO X may be formed. Sulphuric acid reacts
with many metals to liberate hydrogen gas, which can accumulate to explosive concentrations inside confined spaces.

present. For fires close to a spill or where vapours are present, use acid-resistant personal protective equipment.
Prevent fire extinguishing water from contaminating surface water or the ground water system.
SECTION 6: Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
Remove all ignition sources. Ventilate area. Keep unnecessary and unprotected personnel from entering. Keep people
away from and upwind of spill/leak. Wear appropriate personal protective equipment during clean up: acid resistant
clothing and gloves, close-fitting safety goggles and respiratory protection equipment if acid mists are present.
6.2. Environmental precautions
Contamination of soil and water should be prevented. Prevent liquid from entering sewers or waterways.
6.3. Methods and material for containment and cleaning up
Contain and recover liquid when possible. Neutralize with alkaline material, then absorb with an inert material. Do not
use combustible materials
6.4. Reference to other sections
Please refer to section 8 and 13 for more information
SECTION 7: Handling and storage
7.1. Precautions for safe handling
Avoid all unnecessary exposure. Handle in accordance with good industrial hygiene and safety procedures. Keep
ignition sources away from sulphuric acid storage, handling and transportation equipment. Locate safety shower and
eyewash station close to chemical handling area. Take precautionary measures against static discharges.
7.2. Conditions for safe storage, including any incompatibilities
Store in a cool, dry, ventilated storage area with acid resistance floors and good drainage. Keep away from heat, water
and incompatible materials such as alkaline substances. Sulphuric acid must be stored in containers or tanks that have
been specially designed for use with sulphuric acid. Hydrogen gas can accumulate to explosive concentrations inside
