Approximately -7藲C (20藲F) (cc)
Lower flammable limit Upper flammable limit
~0.9% ~6%
Explosion data: Sensitivity to: Mechanical impact Not expected to be sensitive Static discharge Yes
Means of extinction In general, do not extinguish fire unless flow can be stopped. Use carbon dioxide, dry chemical, or
foam. Cool containers with flooding quantities of water until well after the fire is out.
Special precautions Vapour is heavier than air. It will spread along the ground & collect in low or confined areas (sewers,
basements). Also travels to source of ignition and flashes back. Containers may explode when heated.
Hazardous combustion products Carbon monoxide (CO). Nitrogen oxides (NOx). Aromatic hydrocarbons. H2S and sulphur
dioxide (SO2) if product contains sulphur.
SECTION 5 鈥? REACTIVITY INFORMATION
Stability Stable
Conditions to avoid Sources of ignition. Static discharges. High temperatures.
Incompatible substances Oxidizers such as peroxides, nitric acid, and perchlorates.
Hazardous decomposition products CO. NOx. Aromatic hydrocarbons. H2S and SO2 if product contains sulphur.

SECTION 6 鈥? HEALTH HAZARD INFORMATION
Route of Entry Eye Hazardous Contact Eye
Skin absorption Skin
Inhalation
Ingestion
Acute exposure Headache, nausea, dizziness and other symptoms of central nervous system (CNS) depression. Aspiration
into the lungs can cause severe pneumonitis (serious lung irritation), with coughing, gagging, shortness of
breath, chest pain, and/or pulmonary edema (swelling and fluid accumulation).
H2S is very toxic. At concentrations as low as 1 to 5 ppm, nausea and severe eye irritation may occur.
Sense of smell may be impaired at about 20 ppm, with headache and respiratory tract lung irritation. At 250
to 500 ppm, potentially fatal pulmonary edema (fluid in the lungs) may occur. Dizziness, sudden (often fatal)
collapse, unconsciousness, and death occur at higher concentrations. Note: Pulmonary edema may be
delayed as long as 48 hours after exposure.
Chronic exposure Specific information is not available. However, the following is expected, as for gasoline: Peripheral & CNS
damage, such as tremors, hallucinations, memory loss, & impaired mental capacity. Damage to kidneys
and blood-producing system. Prolonged skin contact may cause dermatitis. Fatigue, and severe nervous
and respiratory system symptoms may follow survival of H2S poisoning.
Carcinogenicity Teratogenicity
Not classified by ACGIH, EPA, NTP, NIOSH, or Not available
Reproductive toxicity Not available
OSHA, as to carcinogenicity. IARC lists stoddard
Sensitization No
solvent (a closely-related product) as unclassifiable.
Mutagenicity Irritancy
Not known to be mutagenic No
Toxicologically synergistic products Other CNS depressants are expected to produce additive or synergistic effects.
SECTION 7 鈥? FIRST AID
Do not attempt rescue of an H2S knockdown victim without the use of proper respiratory protective equipment.
Inhalation Move victim to fresh air Give artificial respiration if breathing has stopped and if a qualified AR administrator is
available. Apply CPR if both pulse and breathing have stopped. Obtain medical attention immediately.
Ingestion Never give anything by mouth if the person is unconscious, rapidly losing consciousness, or convulsing. If the
person is conscious, have them drink 8 to 10 ounces of water or milk to dilute the material in the stomach. Do
not induce vomiting. If vomiting occurs spontaneously, have the person lean forward to avoid aspiration. Obtain
medical attention immediately.
Eye Flush eye with lukewarm, gently flowing fresh water for at least 10 minutes. Obtain medical attention.
Skin Quickly and gently blot away excess chemical. Remove and isolate contaminated clothing and shoes. Flush skin
with water for at least 10 minutes. Wash gently and thoroughly with water and non-abrasive soap. Obtain medical
assistance.
SECTION 8 鈥? PRECAUTIONARY MEASURES
Personal Gloves Nitrile or Viton鈩? preferred.
protective Chemical safety goggle or face shield, as a good general safety practice.
Eye
equipment Respiratory NIOSH-approved. A qualified OHS professional should advise on respirator selection. SCBA or air
line respirator with escape cylinder for confined spaces or work with S-containing product.. If an air-
purifying respirator is appropriate, use a 鈥淧 series鈥? filter & organic vapour cartridges.
Clothing & Coveralls to prevent skin contact. If clothing or footwear is contaminated with product, remove it
footwear immediately & completely decontaminate it before re-use, or discard it as flammable waste.
Engineering Enclose processes. Use local exhaust ventilation to remove vapour at its site of generation. Handle
controls laboratory samples in a fume hood. Use mechanical ventilation in confined spaces.
Handling Avoid heating open containers of product so as to minimize vapour production and accumulation. Use non-
procedures & sparking equipment, explosion-proof ventilation, and intrinsically safe electrical equipment. Ground
equipment handling equipment. Have clean emergency eyewash and shower readily available in the work area.
Leak & spill Keep unauthorized persons away. Eliminate all sources of ignition. Ventilate area. Stop leak if it can be
Procedure done safely. Prevent entry into sewers, waterways, or confined spaces. Vapour-suppressing foam may be
used to reduce vapour. Absorb or cover with dry earth, sand or other non-combustible material and use
clean, non-sparking tools to transfer to container.
Waste disposal Consult local authorities for advice.
Storage May be stored at ambient temperatures. Containers should be vented and equipped with a flame arrester.
Shipping Stable during transport.
