SECTION 6 鈥? HEALTH HAZARD INFORMATION
Route of Entry Eye Hazardous Eye
Skin absorption Skin
Inhalation
Ingestion
Acute exposure Central nervous system (CNS) depression, with symptoms of headache, nausea, dizziness, &
drowsiness. Aspiration into the lungs can cause severe pneumonitis (serious lung irritation), with
coughing, gagging, shortness of breath, chest pain, and/or pulmonary edema (fluid collection and
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 Dry cracked skin. Rare cases of 鈥渃hronic organic solvent syndrome鈥?, with symptoms of CNS
exposure depression, memory impairment, joint pain, tiredness, sleep disturbances, decreased manual
dexterity, emotional instability, and reduced ability to concentrate. Aplastic anemia. Rare cases of liver or
kidney impairment. Fatigue, and severe nervous and respiratory system symptoms may follow survival

SECTION 7 鈥? FIRST AID
Do not attempt rescue of an H 2S 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 & gently blot away excess chemical. Remove & isolate contaminated clothing & shoes. Flush skin with
water for at least 10 minutes. Wash gently & thoroughly with water & non-abrasive soap. Obtain medical help.
SECTION 8 鈥? PRECAUTIONARY MEASURES
Personal Gloves Nitrile, Viton鈩?, or Barrier (PA/PE/PA) preferred.

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
procedures & non-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 igniti on. 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 Consult local authorities for advice.
Storage May be stored at ambient temperatures. Containers should be vented and equipped with a flame
