**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes and skin. Very toxic to
aquatic organisms.Dangerous for the environment.Hygroscopic (absorbs
moisture from the air).
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Contact of the eye with resorcinol has caused necrosis and
corneal perforation.
Skin:
Causes moderate skin irritation. 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. If
absorbed, may cause symptoms similar to those for ingestion.
Resorcinol has been known to cause hyperemia (an excess of blood in a
part), itch, dermatitis, edema, and corrosion.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns. May cause methemoglobinemia, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), convulsions, and death.
Inhalation:
Dust is irritating to the respiratory tract. Causes irritation of
the mucous membrane and upper respiratory tract.
Chronic:
May cause liver and kidney damage. Repeated exposure may cause
sensitization dermatitis. Repeated exposure may cause damage to the
spleen.
**** 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, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Persons with skin problems or liver, kidney, lung, or blood diseases
may be at increased risk from exposure to 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. If cyanosis is severe,
intravenous injection of Methylene Blue, 1mg/kg of body weight may be
of value.
**** 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. Dusts at sufficient
concentrations can form explosive mixtures with air. Vapors may be
heavier than air. They can spread along the ground and collect in
low or confined areas.
Extinguishing Media:
Water spray may cause frothing. Cool containers with flooding
quantities of water until well after fire is out. In case of fire,
use carbon dioxide, dry chemical powder or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Do not
get in eyes, on skin, or on clothing. Store protected from light.
Store protected from air. Use only with adequate ventilation. Avoid
breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not expose
to air. Store protected from light.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.

**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Fish: Fathead Minnow: LC50 = 88.6 mg/L; 24Hr; UnspecifiedFish:
Fathead Minnow: LC50 = 72.6 mg/L; 48 Hr; UnspecifiedFish: Fathead
Minnow: LC50 = 53.4 mg/L; 96 Hr; UnspecifiedIf released to soil or
water, biodegradation is expected to be an important fate process
based on the results of a number of biological screening studies
which have suggested that resorcinol is readily biodegradable.
Resorcinol may react relatively rapidly in sunlit natural water with
photochemically produced oxidants such as hydroxyl and peroxy
radicals. Resorcinol is expected to leach readily in soil; however,
leaching may not be important if concurrent biodegradation occurs at
