## Section 3: Hazards Identification

Potential Acute Health Hazards: High vapor concentrations are irritating to the eyes and respiratory tract and may be a central nervous system ( CNS ) depressant (headaches, dizziness and anesthetic effects). In addition, brief contact with liquid may result in a minor irritation. This material may also cause irritation of the eyes upon contact with the liquid.

Potential Chronic Health Hazards: Repeated skin exposure can lead to de

- oiling of the skin. This can c ause dermatitis. Skin absorption is also possible. Continual skin absorption may result in internal organ damage (blood, CNS, kidneys, lungs).


## Section 4: First Aid Measures
Eye Contact: Should eye contact occur, i mmediately flush eyes with large amou nts of water (preferably in an eye wash facility). Flush eyes for at least 15 minutes. A medical evaluation should be obtained as soon as possible. In severe cases, permanent eye damage may result.
Skin Contact: Should skin contact occur, flush the skin with large amounts of water (preferably in a safety shower facility) for at least 15 minutes. Any contaminated clothing should be removed. A local evaluation of the exposed individual should be made by a trained person. If deemed necessary, medical atte ntion should be obtained.
Inhalation: If inhalation of the vapors of this material occurs , the exposed individual must be removed from the area of the exposure. If the victim is not breathing, give artificial respiration. If breathing is difficult, give oxygen. If the victim is having difficulty breathing, get the victim to medical attention immediately. Ingestion: Do not induce vomiting! Get medical attention immediately! Ingestion of large amounts may have systemic effects. 

## Section 5: Fire Fighting Measures
Flammability: Flammable. Keep away from ignition sources and take precautions to prevent a static discharge. This material may present a static accumulating liquid hazard. Vapors may travel along the ground for some distance or be moved by ventilation and ignited by ignition sources at locations distant from the location of the material handling. Flash

- backs can occur at any point along the vapor trail!
Flash Point: <58 ° C

Auto

- ignition Temperature: Not available.

### Flammable Limits in Air: LFL = 1.0%; UFL = 7% (Estimated Values) Suitable Extinguishing Media: For small fires, a Class B extinguishing media (such as dry chemical, CO 2, or AFFF/ATC foam ) or water spray may be used. For larger fires, water spray, water fog AFFF/ATC or

a co mbination of these should be used. Personnel engaged in fire fighting should be properly trained and equipped with proper PPE. NFPA Rating: Health = 1 Flammability = 4 Reactivity = 0



## S ection 6: Accidental Release Measures

Protective Measures: If the spill is large, consider evacuating personnel in the area. Eliminate all ignition sources in the vicinity of the spill. To minimize the area of the spill, plug all drains in the area of the spill. Stop the source of the release if possi ble without risks to the responders. Contain the release to prevent further contamination of soil, surface water and ground water. Wear the proper personal protective equipment while engaged in the spill response. Cover the contaminated area with an ine rt absorbing material such as vermiculite or a commercially available absorbing material. Place the used absorbent material in a suitable container for disposal in a manner consistent with applicable regulations. 

## Section 7: Handling and Storage

Precautio ns: A static electric charge can accumulate when the material is flowing through pipes, nozzles or filters. Always bond receiving container to the fill pipe before and during loading. Always keep the nozzle in contact with container during loading proce ss. Keep in a tightly closed container. Ground/bond all equipment containing the materi al or the equipment that this naphtha is being used in. This material will likely present a static accumulating liquid hazard. Do not ingest the material or breathe the vapor or sprays of the material. Avoid contact with the skin or eyes. Wear the appropriate personal protective equipment when handling this equipment. Treat empty vessels the same as full ones. Empty vessels that have contained this naphtha, becaus e of the residual material in them, could have a flammable

### atmosphere in them. Heating these “empty” vessels could result in an explosion!
Storage: Store in a cool, dry, well ventilated area that is away from ignition sources. Do not store in direct sun light or near other sources of heat. Storing near sources of heat may result in a pressure increase inside the container. Do not store near incompatible materials such as oxidizers. Store containers in a manner that prevents them from suffering physical damage. 

## Section 8: Exposure Control/Personal Protection
Engineering Controls: Use process enclosures, local exhaust ventilation or other engineering controls to keep airborne contamination levels to a safe level . If user operations generate vapors, use ventilation to keep exposures at a level to where they are not a health hazard or where a flammabl e atmosphere will not exist. In ope rations such as these, the use of hazardous classified equipment should be considered. Respiratory Protection: Where va pors are present and engineering controls have been unsuccessful or not available, use NIOSH approved respiratory protection to mitigate potential respiratory exposures. In situations where the levels of the airborne contamination are unknown, use a suppl ied air respirator or a self

- contained breathing apparatus (SCBA). Respirators should be used in accordance with OSHA requirements (29 CFR 1910.134). Eye Protection: For general work, use a minimum of safety glasses with side shields. Where a spray, mis t or heavy vapor may exist, use chemical safety goggles or a full

- face respirator. Although face shields can be used to supplement the level of protection, they should never be used instead of primary eye protection.
Skin Protection: Wear impervious prot ective clothing, including boots, gloves apron or coveralls, as appropriate, to prevent skin contact. Exposure Limits:

- 2) Skin irritation : Repeated or prolonged contact with the preparation may cause removal of natural fat from the skin resulting in desiccation of the skin. The product may be absorbed through the skin. Eye Irritation : The liquid splashed in the eyes may cause irritation and reversible damage. Strong lachrymation can make it difficult to escape Further information : This product contains benzene. Human health studies indicate that prolonged and/or repeated overexposure to b enzene may cause damage to the blood

- forming system (particularly bone marrow), and serious blood disorders such as aplastic anemia and leukemia. Benzene is listed as a human carcinogen by the NTP, IARC, OSHA and ACGIH. Acute toxicity of benzene results pr imarily from depression of the central nervous system (CNS). Inhalation of concentrations over 50 ppm can produce headache, lassitude, weariness, dizziness, drowsiness, or excitation. Exposure to very high levels can result in unconsciousness and death. Sy mptoms of overexposure may be headache, dizziness, tiredness, nausea and vomiting. Ingestion may cause gastrointestinal disturbances, including irritation, nausea, vomiting and diarrhea, and central nervous (brain) effects similar to alcohol intoxication. In severe cases, tremors, convulsions, loss of consciousness, coma, respiratory arrest and death may occur.
