3 Hazard identification
Eyes: Silica gel can cause irritation, Iodine Pentoxide or sulphuric acid can cause severe
irritation or burns
Skin: Avoid contact with silica dust. The drying action of silica can cause irritation. Iodine
Pentoxide or sulphuric acid can cause severe irritation or burns.
Inhalation: Avoid prolonged exposure to silica dust. Iodine pentoxide can cause irritation of
nose and mouth. Iodine pentoxide can cause irritation of the upper respiratory tract. Inhalation
of sulphuric acid can cause severe irritation or burns of respiratory system, pulmonary edema
and lung inflammation.
Ingestion: Can cause nausea, vomiting, severe burns to mouth, throat, and stomach, and
kidney dysfunction.
Medical Conditions Aggravated: Inhalation can aggravate respiratory system disease.
Chromic Overexposure: Chronic inhalation can cause lung damage.
Acute Overexposure: see above
Carcinogenicity: None
4 First aid measures
Eye contact: Immediately wash from eyes with large amounts of water, occasionally lifting
upper and lower eye lids, for at least 15 minutes. If irritation persists seek medical attention.
Inhalation: Remove to fresh air. If not breathing give artificial respiration. If breathing is difficult
give oxygen.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse..

Ingestion: Call a physician. If swallowed, do NOT induce vomiting. If conscious, give large
amounts of water..
5 Fire-fighting measures
Special risks
Non-Flammable.
Suitable extinguishing media and instructions
Use dry chemical or carbon dioxide
Firefighting Instructions: Firefighters should wear proper protective equipment and selfcontained breathing apparatus with full-face piece, operated in positive pressure mode. Move
containers from fire area if it can be achieved without risk. Use water to keep fire-exposed
containers cool. Do not get water inside containers. Iodine pentoxide is a strong oxidiser.
Contact with combustible materials, flammable materials or powdered metals can cause fire
and explosion. A violent exothermic reaction occurs with water. Sufficient heat may be
generated to ignite combustible materials
Hazardous decomposition: Iodine pentoxide emits iodine and highly toxic and irritating fumes.
Sulphuric acid emits sulphur dioxide and hydrogen..
6 Accidental release measures
Wear full protective clothing and breathing apparatus.
Stop leak if you can without risk. Do NOT use water. Keep combustibles (wood, paper, oil etc)
away from spilled material. With a shovel carefully place into a clean, dry container and cover;
remove from area
7 Handling and storage
Handling:
Keep from contact with clothing or other combustible materials. Do not get in eyes, or on skin
or clothing. Avoid breathing dust. Use with adequate ventilation. Wash thoroughly after
handling.
Storage:
Keep container closed. Do not store near flammable or combustible materials.
8 Exposure controls/personal protection
As appropriate to the situation and the quantity handled.
Respirator: If airborne concentration is high, a dust/mist respirator is recommended. If
concentration exceeds capacity of respirator, self-contained breathing apparatus is advised. .
Ventilation: Use general of local exhaust ventilation to keep fume/dust levels as low as
possible.
Skin and Hand protection: Select glove appropriate for the specific operation, wear an apron.
Eye protection: Safety goggles.
Other precautions: Not available.
9 Physical and chemical properties
Form: Pale yellow granules
Odour: None

Melting temperature: Not established.
Boiling temperature: Not established
Solubility in water: slightly soluble
Flash point: Not established
Ignition temperature: N/A
Specific Gravity: Not established
10 Stability and Reactivity:
Chemical stability: Stable
Incompatibility: Silica gel reacts with hydrofluoric acid. Iodine pentoxide reacts with light,
moisture, organic materials, strong reducing agents and combustible materials. Sulphuric acid
is incompatible with moisture, heat, water, most common metals, organic materials, strong
bases, carbonates, sulphides, cyanides, strong oxidising agents and carbides
Hazardous Decomposition Products: Iodine pentoxide can release iodine. Sulphuric acid can
release oxides of sulphur and hydrogen.
Hazardous Polymerisation: None
11 Toxicological information
Silica gel finely ground
1-hour Rat LC50:>2mg/l 48-hour Rat Oral LD50:est.>31,600 mg/kg
48-hour Rabbit Dermal LD50: est.>2,000 mg/kg Not considered an ocular irritant.
Silica gel is a synthetic amorphous silica not to be confused with crystalline silica
Epidemiological studies indicate low potential for adverse health effects. Silica gel is
considered to be a nuisance dust.
Sulphuric Acid:
Oral Rat LD50: 2140mg/kg 2hr Mouse inhalation LC50: 320 mg/m3
2hr Rat inhalation LC50: 510 mg/m3

13 Disposal considerations
Chemical residues are generally classified as special waste, and as such are covered by
regulations which vary according to location. Contact your local waste disposal authority for
advice, or pass to a chemical disposal company.
