**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Possible risks of irreversible
effects.Air sensitive.Light sensitive.
Potential Health Effects
Eye:
Causes eye irritation and burns.
Skin:
May be absorbed through the skin in harmful amounts. May cause skin
sensitization, an allergic reaction, which becomes evident upon
re-exposure to this material. Causes severe skin irritation and
burns. Contact with skin may cause discoloration and eczema.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. Causes gastrointestinal tract burns.
Rapidly absorbed from the gastrointestinal tract. Ingestion may
cause weakness, muscular incoordination, fine tremors, loss of
reflexes, convulsions and possible death from circulatory collapse.
Inhalation:
May cause respiratory tract irritation. May cause methemoglobinemia,
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), convulsions, tachycardia, dyspnea (labored breathing),
and death. May cause severe irritation of the respiratory tract with
sore throat, coughing, shortness of breath and delayed lung edema.
May be harmful if inhaled. May be absorbed through the lungs.
Chronic:
May cause liver and kidney damage. Absorption into the body leads to
the formation of methemoglobin which in sufficient concentrations
causes cyanosis (bluish discoloration of skin due to deficient
oxygenation of the blood). Repeated exposure may cause sensitization
dermatitis. May cause reproductive and fetal effects. Laboratory
experiments have resulted in mutagenic effects. Pyrogallol has a
tremendous affinity for oxygen of the blood and may cause death by
respiratory failure.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
Notes to Physician:
Persons with pre-existing skin disorders or eye problems, or
impaired liver, kidney, or respiratory function may be more
susceptible to the effects of this substance. Absorption of this
product into the body may cause cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood). Moderate degrees of
cyanosis need to be treated only by supportive measures: bed rest and
oxygen inhalation. For methemoglobinemia, administer oxygen alone or
with Methylene Blue depending on the methemoglobin concentration in
the blood.
**** 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation. Place under an inert atmosphere.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Do not breathe
dust, vapor, mist, or gas. Do not get in eyes, on skin, or on
clothing. Do not ingest or inhale. Store protected from light. Handle
under an inert atmosphere. Store protected from air.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area. Do not expose to air. Absorbs oxygen from the air and will
darken upon exposure. Store protected from light. Store under an
inert atmosphere.
**** 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.

**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Fish: Goldfish: LC50 = 18 mg/L; 48 Hr; CAS# 87-66-1: UnspecifiedWater
flea Daphnia: EC50 = 54 mg/L; 24 Hr; CAS# 87-66-1: UnspecifiedFish:
Mosquito Fish: LC50 = 80.0 mg/L; 24 Hr; CAS# 1310-58-3
UnspecifiedCAS# 87-66-1: Estimated Koc value = 3.2. This value
indicates that pyrogallol will show very high soil mobility and will
not adsorb to sediment or particulate matter in water. Volatilzation
from moist or dry soils and water sources is not expected. Estimated
BCF value = 0.37. This value suggests that bioconcentration of
pyrogallol in aquatic organisms should be low.
Other
Harmful to aquatic life in very low concentrations.
