**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Causes
burns.Stench.
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
May be fatal if absorbed through the skin. Causes skin burns.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns.
Mercaptans may cause nausea and headache. Exposure to high
concentrations of mercaptans can produce unconsciousness with
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), cold extremities and rapid pulse.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema.
Olfactory fatigue may occur. Exposure to high concentrations of
mercaptans can produce unconsciousness with cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood),
cold extremities and rapid pulse. Mercaptans may cause nausea and
headache.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
POISON material. In case of contact, get medical aid immediately.
Immediately flush eyes or skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash
clothing before reuse. Destroy contaminated shoes.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Approach fire from upwind to avoid hazardous vapors
and toxic decomposition products.
Extinguishing Media:
Water or foam may cause frothing. Use water spray, dry chemical, or
carbon dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing.
Discard contaminated shoes. Do not breathe vapor or mist. Use only
with adequate ventilation or respiratory protection.
Storage:
Keep refrigerated. (Store below 4C/39F.) Keep container closed
when not in use. Corrosives area. Store in a cool, well-ventilated
area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
