**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. Irritating to respiratory system.
Potential Health Effects
Eye:
May cause irreversible eye injury. Vapor or mist may cause
irritation and severe burns. Contact with liquid is corrosive to the
eyes and causes severe burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration. The severity of injury depends on the concentration of
the solution and the duration of exposure.
Ingestion:
Causes severe digestive tract burns with abdominal pain, vomiting,
and possible death. May cause corrosion and permanent tissue
destruction of the esophagus and digestive tract.
Inhalation:
May be fatal if inhaled. May cause severe irritation of the
respiratory tract with sore throat, coughing, shortness of breath
and delayed lung edema. Causes chemical burns to the respiratory
tract. Causes corrosive action on the mucous membranes.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Repeated
exposure may cause erosion of teeth. Repeated exposure to low
concentrations of HCl vapor or mist may cause bleeding of nose and
gums. Chronic bronchitis and gastritis have also been reported.
**** 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:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
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:
Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
**** 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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. Not flammable, but reacts with
most metals to form flammable hydrogen gas. Use water spray to keep
fire-exposed containers cool. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Containers may explode when heated.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Isolate area and deny entry. Provide ventilation.
Spill may be carefully neutralized with lime (calcium oxide, CaO). A
vapor suppressing foam may be used to reduce vapors. Approach spill
from upwind.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Contents may develop pressure upon prolonged
storage. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Do not ingest or inhale. Discard contaminated shoes.
Keep away from strong bases and metals. Use caution when opening. Do
not use with metal spatula or other metal items. Do not breathe
vapor or mist. Use only with adequate ventilation or respiratory
protection.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Corrosives area. Do not store in metal containers. Store
away from alkalies. Separate from oxidizing materials.
**** 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. Use a corrosion-resistant ventilation
system.
