combustible and reducing substances, strong oxidants, strong bases,
food and feedstuffs, incompatible materials. See Chemical Dangers.
May be stored in stainless steel containers. Store in an area having
corrosion resistant concrete floor.
COLOURLESS, OILY, HYGROSCOPIC LIQUID, WITH NO ODOUR.
The substance is a strong oxidant and reacts violently with combustible
and reducing materials. The substance is a strong acid, it reacts
violently with bases and is corrosive to most common metals forming
a flammable/explosive gas (hydrogen - see ICSC 0001). Reacts violently
with water and organic materials with evolution of heat (see Notes).
Upon heating, irritating or toxic fumes (or gases) (sulfur oxides)
Occupational exposure limits
TLV: 1 mg/m³ (as TWA);
3 mg/m³ (as STEL) A2 sulfuric acid contained in strong inorganic
acid mists (ACGIH 2000).
MAK: 1 mg/m³; inhalable fraction of aerosol (1999).
The substance can be absorbed into the body by inhalation of its aerosol
and by ingestion.
Evaporation at 20°C is negligible; a harmful concentration
of airborne particles can, however, be reached quickly on spraying.
Effects of short-term exposure
Corrosive. The substance is very corrosive to the eyes the skin
and the respiratory tract. Corrosive on ingestion. Inhalation of
an aerosol of this substance may cause lung oedema (see Notes).
Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolonged exposure to an aerosol
of this substance. Risk of tooth erosion upon repeated or prolonged
exposure to an aerosol of this substance. Strong inorganic acid
mists containing this substance are carcinogenic to humans.

of lung oedema often do not become manifest until a few hours have
passed and they are aggravated by physical effort. Rest and medical
observation are therefore essential.
NEVER pour water into this substance; when dissolving or diluting
always add it slowly to the water.
