Potential Health Effects
----------------------------------

Inhalation:
Inhalation of vapor or mist is irritating to the respiratory tract. May produce headache, nausea, vomiting. High concentrations can produce central nervous system depression. The predominant reaction of overexposure from the naphthalene component is delayed intravascular hemolysis with symptoms of anemia, fever, jaundice and kidney or liver damage.
Ingestion:
May cause nausea, headache, vomiting and intragastric discomfort. Major hazard (from the decahydronaphthalene component) is aspiration into lungs, which may result in pulmonary edema or chemical pneumonia.
Skin Contact:
Causes skin irritation with discomfort, rash. Sensitized individuals (from naphthalene exposure) may suffer a severe dermatitis.
Eye Contact:
Vapor causes irritation, redness and pain. The naphthalene component, at very high concentrations, can damage the nerves of the eye.
Chronic Exposure:
May cause cataract and kidney and liver damage. Chronic naphthalene exposure has led to cataract formation and may cause skin allergy.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin, eye, kidney or liver, blood or vascular disorders or impaired respiratory function may be more susceptible to the effects of the substance. Particularly susceptible individuals (for naphthalene exposure) are found in the general population, most commonly in dark skinned races.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion:
Do NOT induce vomiting. Give large amounts of water. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of soap and water. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

5. Fire Fighting Measures

Fire:
Flash point: 71C (160F) CC
Autoignition temperature: 385C (725F)
Flammable limits in air % by volume:
lel: 0.8; uel: 5.0
Combustible Liquid and Vapor!
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Vapors can flow along surfaces to distant ignition source and flash back. Can form explosive peroxides which may be concentrated by evaporation or distillation.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide. Water may be ineffective. Water spray may be used to keep fire exposed containers cool.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! For the naphthalene component: US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802.

J. T. Baker SOLUSORB(tm) solvent adsorbent is recommended for spills of this product.

7. Handling and Storage

Protect against physical damage. Outside or detached storage is preferred. Inside storage should be in a standard flammable liquids storage room or cabinet. Separate from oxidizing materials. Storage and use areas should be No Smoking areas. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
For Naphthalene:
-OSHA Permissible Exposure Limit (PEL):
TWA = 10 ppm, 50 mg/m3

-ACGIH Threshold Limit Value (TLV):
TWA = 10 ppm, 52 mg/m3;
STEL = 15 ppm, 79 mg/m3

Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face respirator with an organic vapor cartridge and dust/mist filter may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece respirator with an organic vapor cartridge and dust/mist filter may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.

10. Stability and Reactivity

Stability:
Stable under ordinary conditions of use and storage. Contact with air may cause formation of tetralin peroxide. Potentially explosive peroxides can form on long-term storage in contact with air. Light and heat accelerate peroxide formation.
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition. Under pyrolysis at 700C yields tars that contain 3,4-benzopyrene.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Strong oxidizers.
Conditions to Avoid:
Heat, flame, ignition sources, air, light and incompatibles.
