3. HAZARDS IDENTIFICATION/EMERGENCY OVERVIEW:
Routes of Entry: Absorption, inhalation, ingestion, skin contact, and eye contact.
Effects of Acute Exposure: This material has a strong corrosive effect on the skin and eyes.
The material can rapidly absorb through the skin and may cause death. Nausea, headache,
respiratory failure, muscular weakness, gastroenteric disturbances, severe depression, collapse, and
death. Minor to severe chemical burns. Redness or blisters to dermatitis. Although the effects are
primarily on the central nervous system, edema of the lungs and injury of the kidneys, liver,
pancreas, and spleen may occur. DANGER ! ! ! Rapid DEATH may occur from gross
contamination of the body.
Effects of Chronic Exposure: Organs affected by long term exposure may include the
respiratory system, central nervous system, skin, eyes, lungs, kidneys, and liver. Chronic exposure
may cause gastrointestinal disturbances (vomiting, anorexia), nervous disorders (headache,
dizziness), dermatitis, or pigmentary disorder. Serious and sometimes fatal systemic injury can
result from chronic exposure.
Odor character/threshold: Has a sweet, medicinal, irritating odor.
Odor Threshold: 0.00060 ppm.
POTENTIAL HEALTH EFFECTS:
EYE CONTACT: This material has a strong corrosive effect on the eyes. Eye irritation has
been noted following brief exposures to concentrated vapors.
SKIN CONTACT: This material has a strong corrosive effect on the skin. Death has
occurred from 64 sq. in. of skin exposure. Burns will result from skin
contact. Even dilute solutions may cause severe burns if contact is
prolonged. Systemic toxicity can result from skin or eye exposures.
INHALATION: Edema of the lungs, and respiratory failure. Ingestion can be fatal. Will
act as a respiratory irritant when inhaled as a concentrated aerosol.
Levels causing irritation have not been reliably documented. Exposure to
Product Name: Cresylic Acid - Dephenolized Page 2 of 9
Revision Date: 08/03/07
concentrations of 1.5 ppm may cause mucosal irritation symptoms
including dryness, nasal constriction, and throat irritation.
Gastroenteric disturbances. Ingestion can be fatal.
INGESTION:
4. FIRST AID MEASURES
EYES: Remove the victim from the source of contamination and take him to the
nearest eyewash, shower, or other source of clean water. Immediately
but gently brush, blot, or wipe away any liquid or powdered chemical
remaining on the face, being careful not to get it on your skin. Gently
rinse the affected eye(s) with clean, lukewarm water for at least 15
minutes. Have the victim lie or sit down and tilt his head back. Hold the
eyelid(s) open and pour water slowly over the eyeball(s) at the inner
corners, letting the water run out of the outer corners. The victim may be
in great pain and want to keep his eyes closed but you must rinse the
chemical out of his eye(s) in order to prevent permanent damage. Ask
the victim to look up, down and side to side as you rinse in order to better
reach all parts of the eye(s). Seek medical attention immediately.
SKIN: Rapid skin decontamination is critical. Skin exposure of 64 sq. in. has
caused fatality. Skin contact can be life threatening. The victim may not
be aware of initial skin contact because of local anaesthetic effect of
phenol. Remove clothing, shoes, socks, and jewelry from the affected
areas as quickly as possible, cutting them off if necessary. Be Careful
not to get any chemical on your skin or clothing. Blot excess chemical
from the skin very gently. In case of extensive splashing, wash the victim
down under a shower under cold or luke-warm water while protecting the
victim's eyes. Rinse the skin area for at least 15 minutes. Keep victim
quiet and maintain normal body temperature. If burns develop, such as
inflammation or blisters, apply a dry sterile dressing or use a clean dry
cloth. Elevate the affected area above the level of the victim's heart if
possible. If the victim is in pain, immerse the painful area in cold water or
apply cold wet dressings. DO NOT break open blisters or remove skin. If
clothing is stuck to skin after flushing with water, do not remove it. DO
NOT use hot water. Seek medical attention immediately.
INHALATION: Remove victim to fresh air at once. Initiate artificial respiration and supply
oxygen if needed. Keep victim warm and at rest. Seek medical attention.
If patient is conscious, the irritation of the throat may be relieved by water
in the mouth. Seek medical attention immediately.
INGESTION: A conscious victim should immediately drink 4 to 8 ounces of water, and
then a slurry of activated charcoal to reduce the concentration of the
chemical. Have him rinse his mouth several times with cold water and
spit out. Do not induce vomiting. Do not give sodium bicarbonate or
carbonated drinks. Keep victim warm and quiet. Seek medical attention
immediately.

PROCEDURES: water into an appropriate chemical drain. Employees not
wearing protective equipment and clothing should be restricted
from areas of spills or leaks until cleanup has been completed.
Remove all ignition sources. Ventilate area of spill or leak.
Small quantities of liquid can be absorbed onto paper towels
and placed in an appropriate container. Place in a lab hood for
evaporation. Larger quantities of liquids may be absorbed in
vermiculite, dry sand, earth or similar material and placed into
a removable head steel drum. Do not wash material into
sewers or confined space because of the possibility of an
explosion.
WASTE DISPOSAL METHOD: Spills or releases should be reported, if required, to the local,
state, and federal regulatory agencies. The materials resulting
from clean-up operations of a spill may be hazardous and
therefore subject to specific regulations.
Package, store, transport, and dispose of all clean-up
materials and any contaminated equipment in accordance with
all applicable local, state, and federal regulations. Shipments
of waste materials may be subject to manifesting requirements
per applicable regulations. Appropriate disposal will depend
on the nature of the waste and should be performed by
competent personnel.

AFFECTED BY
LONG-TERM
EXPOSURE:
12. ECOLOGICAL INFORMATION
Cresols degrade rapidly in the environment and concentrations in water, even in worst case
conditions, would not approach the levels that would pose a chronic aquatic toxicity hazard. Their
half-life is 70 days or less.
For benthic crustaceaus concentrations below 0.525-0.70 mg cresols/liter of water were not acutely
toxic. The 24hr - LC50 values for fish are 15-30, 21-25, and 14-21 mg/liter. Of the three isomers, m-
cresol appears to be the least toxic to fish.
The vapor pressure of the isomeric cresols suggests that these compounds will evaporate slowly.
The relatively high water solubility of the cresol isomers indicates that wet deposition may remove
them from the atmosphere. This is confirmed by the detection of cresols in rainwater.
The short atmospheric residence time expected for the cresols suggests that cresols will not be
transported long distances from their initial point of release.
All cresol isomers appear to be rapidly removed from environmental media.
13. DISPOSAL CONSIDERATIONS
Containers of this material may be hazardous when emptied, since emptied containers retain
product residues (vapors and liquid). Do not cut, puncture, or weld on or near the container. Do not
reuse "empty" containers without first commercially cleaning, triple rinsing, or equivalent.
Please be advised that state and local requirements for waste disposal may be more restrictive or
otherwise different from federal regulations. Consult state and local regulations regarding the proper
disposal of this material.
