VI. HEALTH HAZARD DATA (Continued)
CHRONIC HEALTH HAZARDS:
The following chronic (long-term) effects can occur at some time after exposure to
Dodecylbenzene Sulfonic Acid and can last for months or years:
CARCINOGENICITY: has not been tested for its ability to cause cancer in animals.
NTP (National Toxicology Program)? No.
IARC (International Agency for Research on Cancer)? No.
OSHA REGULATED? No.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Asthma, other respiratory
disorders (bronchitis, emphysema, bronchial hyperreactivity), skin allergies, eczema.
EMERGENCY & FIRST AID PROCEDURES:
INHALATION- Move to an area free from risk of further exposure. Administer oxygen or
artificial respiration as needed. Obtain medical attention. Asthmatic-type symptoms may develop and
may be immediate or delayed up to several hours. Consult physician should this occur.
SKIN- Remove contaminated clothing. Wash affected skin thoroughly with soap and water.
Wash contaminated clothing thoroughly before reuse. For severe exposures, get under safety shower after
removing clothing, then get medical attention. For lesser exposures, seek medical attention if irritation
develops or persists after the area is washed.
EYE- Flush with copious amount of water, preferably, lukewarm water for at least 15 minutes,
holding eyelids open all the time to ensure that the eyes are being irrigated. Refer individual to physician
or ophthalmologist for immediate follow-up.
INGESTION- DO NOT INDUCE VOMITING. Wash mouth out with water. DO NOT GIVE
ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. Consult physician.
NOTE TO PHYSICIAN:
INHALATION / RESPIRATORY- This compound is a known pulmonary sensitizer. Treatment is
essentially symptomatic. An individual having a pulmonary sensitization reaction to this material should
be removed from exposure to any isocyanate.
SKIN- This compound is a known skin sensitizer. Treat symptomatically as for contact dermatitis
or thermal burns. If burned, treat as thermal burn. An individual having a skin sensitization reaction to
this material should be removed from exposure to any isocyanate.
EYE - Stain for evidence for corneal injury. If cornea is burned, instill antibiotic steroid
preparation frequently. Workplace vapors have produced reversible corneal epithelial edema impairing
vision.

VII. PRECAUTIONS FOR SAFE HANDLING & USE
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
o Identify the material.
o Evacuate 鈥渋mmediate鈥? spill area and keep nonessential or unprotected personnel away.
o Remove any ignition sources.
o Contact your supervisor.
o Ventilate spill area.
o Equip clean-up personnel with full protective equipment (recommend eye & face protection,
permeation-resistant gloves, permeation-resistant suit, permeation-resistant boots, & respirator.)
o Control the source by stopping the spill, leak, or other flow of product.
o Contain or dike the spilled product, creating a barrier around the spill and the inlet to any sewers
or drains.
o Prevent spilled material from entering soil, sewers, surface water, ground water, streams, or any
other bodies of water.
o If temporary control of isocyanate vapor is required, a blanket of protein foam (available at most
fire departments) may be placed over the spill.
o Retain any contaminated water for removal and treatment.
o Absorb small spills with inert absorbent material (e.g. vermiculite, saw dust, clay earth, sweeping
compound, sand, etc.).
o Large spills may be pumped or vacuumed into a closed, but not sealed container for disposal and
then finished off with dry absorbent, followed by neutralizing solution.
o Apply neutralizing solution (see below) over spill area & absorbent.
o Scoop up absorbed material and remaining absorbent/decontaminant mixture and place in a metal
drum or other approved chemical waste container (a closed, but not sealed container).
o Transport container to well-ventilated area (outside, etc.)
o Apply neutralizing solution to the absorbed material in the waste container to ensure adequate
decontamination. Lid should remain loose but not sealed or tightened as dangerous pressures may
result from the neutralization process.
o Monitor the drum frequently for the next 48-72 hours in case overpressurization results from
continued reaction and while carbon dioxide escapes.
o Decontaminate receiving surface (floor, etc.) with neutralizing solution and let it stand for at least
15 minutes.
o Decontaminate tools & protective equipment.
o Remove protective equipment.
o Properly dispose of isocyanate contaminated materials & equipment that cannot be
decontaminated. (Incineration is the preferred method.)
o NOTE: Acceptable neutralizing solutions (ie. decontamination solutions) are:
80% water + 20% non-ionic surfactant such as Dow/Union Carbide Tergitol TMN-10 (or
other non-ionic surfactant which is liquid & mixes well with water)
OR 90% water + 3-8% concentrated ammonia + 2-7% detergent.
o Recommended ratio for thorough decontamination is 1 part of spilled material to 10 parts of
neutralizing solution.
o Report spill per regulatory requirements.
WASTE DISPOSAL METHOD: Waste must be disposed of in accordance with federal, state, and local
environmental control regulations. Incineration is the preferred method.
Revision Date: 8/26/05 MSDS
Product: AD28 Page 4 of 6
EMPTY CONTAINER PRECAUTIONS: Empty containers must be handled with care due to product
residue. Decontaminate containers prior to disposal. Acceptable neutralizing solutions (ie.
decontamination solutions) are:
80% water + 20% non-ionic surfactant such as Dow/Union Carbide Tergitol TMN-10 (or
other non-ionic surfactant which is liquid & mixes well with water)
OR 90% water + 3-8% concentrated ammonia + 2-7% detergent.
Empty decontaminated containers should be crushed to prevent reuse. Do not heat or cut empty
container with electric or gas torch. (See Sections IV-Fire & Explosion Hazard Data and Section V-
Reactivity Data). Vapors and gases may be highly toxic.
VII. PRECAUTIONS FOR SAFE HANDLING & USE (Continued)
PRECAUTIONS TO BE TAKEN IN HANDLING & STORING: Store in tightly closed containers to
prevent moisture contamination. Do not reseal if contamination is suspected. Avoid contact with skin
and eyes. Do not breathe aerosols or vapors. Warning properties (irritation of the eyes, nose and throat or
odor) are not adequate to prevent chronic overexposure from inhalation. This material can produce
asthmatic sensitization upon either single inhalation exposure to a relatively high concentration or upon
repeated inhalation exposure to lower concentrations. Employee education and training in the safe use
and handling of this compound are required under the OSHA Hazard Communication Standard.
SPECIAL SENSITIVITY (HEAT, LIGHT, MOISTURE):
VIII. CONTROL MEASURES (INCLUDING PERSONAL PROTECTION)
VENTILATION:
RESPIRATORY PROTECTION:
SKIN PROTECTION: Permeation resistant gloves (butyl rubber, nitrile rubber, polyvinyl alcohol).
However, please note that PVA degrades in water. Cover as much of the exposed skin area as possible
with appropriate clothing. If skin creams are used, keep the area covered by the cream to a minimum.
EYE PROTECTION: Chemical goggles should be used in a splash hazard environment. For additional
protection, chemical goggles should be used in combination with a full face shield. Contact lenses should
not be worn when working with chemicals.
MONITORING:.
MEDICAL SURVEILLANCE: Medical supervision of all employees who handle or come in contact with
isocyanates is recommended. This should include pre-employment and periodic medical examinations.
The pre-employment exam should include a respiratory health history, a clinical examination, and
baseline pulmonary function testing (FEV, FVC as a minimum). History of adult asthma, respiratory
allergies (such as hay fever), eczema, history of prior isocyanate sensitization, or lack of smell (anosmia)
are possible reasons for medical exclusion from isocyanate areas. Once a person is accurately diagnosed
as sensitized to an isocyanate, no further exposure can be permitted.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Safety showers and eyewash stations should be
available.
WORK/HYGIENIC PRACTICES: Wash hands, forearms, and face thoroughly after handling compounds
and before eating, smoking, using lavatory, and at the end of the day. Educate and train employees in safe
use of product. Follow all label instructions.
