pose an explosive risk in an enclosed space/container.
5.3 Advice for firefighters
Wear self-contained breathing apparatus and full firefighting turnout
gear.
Evacuate personnel to a safe area. Wear full protective clothing.
Runoff from fire control may cause pollution. Wear self-contained
breathing apparatus if fumes or mists are present.

When material is not involved in fire, do not use water on
material itself.
SECTION 6: ACCIDENTAL RELEASE MEASURES
6.1 Personal precautions, protective equipment and emergency procedures
Ensure adequate ventilation, especially in confined areas. Ventilate
affected area. Personnel involved in clean-up should wear
protective gloves/protective clothing and eye/face protection.

Prevent further leakage or spillage if safe to do so. Do not
contaminate water. Place waste in an appropriately labeled sealed
container for disposal. Special care should be taken to avoid
environmental release.
6.3 Methods and materials for containment and cleaning up
Cleaning/Collecting measures:
Contain the source of spill if it is safe to do so.
Sweep up as much as possible and transfer to plastic containers for
recovery or disposal.
6.4 Additional consideration for large spills
Non-essential personnel should be removed from affected area.
Clean up operators should be undertaken by trained personnel.
SECTION 7: HANDLING AND STORAGE
7.1 Precautions for safe handling
Avoid contact with eyes and prolonged skin contact. Avoid
breathing mist. Use appropriate personal protective equipment.
Do not add water to acid. When diluting, always add acid to
water cautiously, and with agitation. Use only with adequate
ventilation.
See section 8 of the SDS for personal protective equipment.
7.2 Conditions for safe storage, including any incompatibilities
Store in a cool, wee-ventilated area away from combustibles and

SECTION 10: STABILITY AND REACTIVITY
10.1 Reactivity
React violently with water, organic materials and base solutions with
generation of heat and hazardous mists.
10.2 Chemical stability
Stable under normal conditions.
10.3 Possibility of hazardous reactions
Hazardous polymerization does not occur.
10.4 Conditions to avoid
Sources of ignition, heat, humidity.
10.5 Incompatible materials
Avoid contact with Water, alkaline solutions, metals, metal powders,
carbides, chlorates, fulminates, nitrates, picrates, strong oxidizing
agents, reducing or combustible organic materials.
Hazardous gases are evolved on contact with chemicals such as
cyanides, sulfides, and carbides. Sulfuric acid reacts with metals to
produce hydrogen, a flammable and potentially explosive gas.
Hydrogen reacts with sulfides and generates hydrogen sulfide
(Highly toxic gas). Never add water and strong bases directly to
sulfuric acid because a violent exothermic reaction may occur.
10.6 Hazardous decomposition products
Thermal decomposition will yield sulfur oxides (SO2, SO3).
