IV. FIRST AID
INHALATION
Symptom: - Inhalation of this powder in sufficient quantities may cause
irritation of the upper respiratory passages, nose & throat. Gross over
exposure may cause ulceration of mucous membranes.
Treatment: - Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
SKIN CONTACT
Symptom: - If allowed to become moist the dry powder may cause severe
irritation and in cases of prolonged contact may cause burns or ulceration.
Contact with the dry powder may cause skin irritation with discomfort or rash,
or allergic skin reactions in sensitive individuals.
Treatment: - Flush skin with plenty of water. Remove contaminated clothing
& shoes after use. Call a physician. Wash contaminated clothing before
reuse.
EYE CONTACT
Symptom: - Eye contact with the powder may cause eye corrosion or ulceration;
eye irritation with discomfort, tearing or blurring of vision. Severe eye damage may
result if not treated immediately.
Treatment: - In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Call a physician.
INGESTION
Symptom: - Ingestion of this product in sufficient quantities may cause
gastritis, with stomach pain, nausea, vomiting, diarrhoea, headache or
weakness; possibly progressing to necrosis or haemorrhage with gross
overexposure.
Treatment: - If swallowed, do not induce vomiting. Give 2 glasses of water
immediately. Never give anything by mouth to an unconscious person. Call a
physician.
V. FIRE FIGHTING MEASURES
Flammable properties: Not applicable
Extinguishing media: Water, dry powder (sand or Met-L-X), CO2.
Fire Fighting instructions: Evacuate personnel to a safe area. Wear self-contained
breathing apparatus (SCBA) & full protective equipment. When heated above 70oC,
decomposes with evolution of corrosive gas (SO2). Virkon S itself is not flammable or
oxidizing, but may assist combustion of other materials under exceptional circumstances.

VI. ACCIDENTAL RELEASE PROCEDURES
Safeguards (Personnel).
Review FIRE FIGHTING MEASURES & HANDLING sections. Use appropriate
Personal Protective Equipment during clean- up.
Environmental precautions: Do not allow the powder concentrate to enter
drains. Infrequent disposal of small quantities (<0.5kg) may be diluted to waste
with large quantities of water, subject to local waste disposal regulations. Do not
allow entry to surface waters.
Methods for clean up: Sweep up carefully, preferable with the aid of a suitable
dry anti-dusting agent if available. Place in suitable containers for disposal.
Prevent powder from becoming moist while awaiting disposal, if possible. Moist
product awaiting disposal must be kept away from combustible material & stored
in a manner that allows suitable ventilation of the waste.
VII. HANDLING AND STORING
Handling Personnel: Avoid inhalation. Do not get in eyes and avoid contact with
skin. Wear Personal Protective Equipment in accordance with section 8.
Handle with sufficient care to prevent dust generation.
Storage: Keep containers tightly sealed & avoid coming into contact with
moisture during storage. Keep containers tightly Keep away from combusti ble
material. Avoid contamination of the product.
1% solution: Store in a clean, loosely capped plastic container at room
temperatures, and away from direct sunlight. Do not allow solution to freeze.
Discard any used or contaminated solution & dispose o f any stock solutions after
7 days from date of preparation.
VIII. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls:
Appropriate Local Exhaust Ventilation may be necessary for handling the product
where dust formation is a problem, i.e. product in bulk quantities, or operations in
small and/or poorly ventilated areas. Not normally necessary for preparation of
solutions from small pack sizes (10lb or less).
Personal Protection Equipment:
Respiratory: Where a Health and Safety assessment shows the dusting levels
to be sufficiently high when handling the powder product, wear a NIOSH
approved respiratory mask against fine particles. Respiratory protection is not
normally considered necessary when handling solutions of diluted product.
However, when working with spray mists of Virkon S, respiratory protection in the
form of a NIOSH approved respirator unit in conjunction with an organic vapor 鈥?
fine particle filter cartridge.
Protective clothing:
Eye: Chemical splash goggles.
Skin: Overalls.
Hand: Rubber gloves.

Exposure Guidelines & Applicable Exposure Limits:
Potassium peroxomonosulfate
PEL (OSHA): None Established
TLV (ACGIH): None Established
AEL* (DuPont): 1 mg/m3, total dust, 8 & 12 hr. TWA
Sulfamic Acid
PEL (OSHA): None Established
TLV (ACGIH): None Established
AEL* (DuPont): 0.5 mg/m3, 8 & 12 Hr. TWA
1.5 mg/m3, 15 minute TWA

IX. PHYSICAL AND CHEMICAL PROPERTIES
Boiling point: Decomposes on heating
Solubility in water: Approximately 8.3oz/gal
Form: Free flowing powder
Color: Yellow
Specific gravity: ~1.07
X. STABILITY AND REACTIVITY
Chemical stability: Stable at normal temperatures & storage conditions.
Incompatibility with other materials: Incompatible with strong alkalis. In contact
with halogen salts (e.g. KC1, KBr, K1, NaCl), Virkon S may react to release toxic
halogen gases, such as chlorine, bromine & iodine. In exceptional cases Virkon S
may support combustion; avoid contact with combustible materials.
Decomposition: Under certain extreme conditions sulphur dioxide & chlorine may
be generated if the powder is allowed to become mois t.
Polymerisation: Polymerisation will not occur.
XI. TOXICOLOGICAL INFORMATION (Animal Data- VIRKON-S POWDER)
Acute Dermal Toxicity: LD50 >2.0g/kg (rabbit).
Acute Oral Toxicity: LD50 = 1.70g/kg (male rats) & 1.16g/kg (female rats)
Acute Inhalation Toxicity: 4 hour LC50 > 6.147mg/1 (male & female rats).
Guinea Pig Dermal Sensitisation: Virkon S displayed no fatiguing or sensitising
effects.
Primary Skin Irritation: The powder is corrosive to the skin of rabbits with an
irritation index of 7.00. A dilution of 5% results in an irritation index of 0.08 in
rabbits.
Primary Eye Irritation: The powder is corrosive to rabbit鈥檚 eyes. A dilution of 5%
produces conjunctival irritation.
Effects of Overexposure: Inhalation of dust may cause choking, coughing or
wheezing. A 1% solution is normally non-irritating.
