3. Hazard Identification
Appearance and Odor: Opaque, off-white liquid with mild odor.
Primary Health Hazards: Irritant
Primary Route(s) of Exposure:
Ingestion: Not a likely source of exposure
Skin: Brief contact is not expected to be harmful. Prolonged or repeated contact may cause
moderate irritation.
Inhalation: Not a likely source of exposure due to low vapor pressure. Product dispersed as a fog or
mist may cause irritation.
Eye: Mild irritant, temporary redness or burning may occur.
Medical Conditions Generally Aggravated by Exposure: Dermatitis.
Signs and Symptoms of Exposure:
Acute Health Hazards: NAP
Chronic Health Hazards: Information available on the chronic health effects from long-term exposure is
limited. Repeated or prolonged skin contact cause moderate irritation and possibly dermatitis.
Carcinogenicity Listing:
NTP: Not Listed
IARC Monographs: Product ingredient, severely solvent refined heavy paraffinic petroleum
distillate, is not classifiable as to its carcinogenicity to humans (Group
3). Severely solvent-refined heavy paraffinic oils have undergone
processing which significantly reduces or removes potentially
carcinogenic 3-7 ring polycyclic aromatic hydrocarbons (polynuclear
aromatic hydrocarbons [PAHs]). 鈥淐hemical Profile 鈥? CHEMINFO

4. Emergency and First-Aid Procedures
Ingestion: If swallowed, give two glasses of water (pint/0.5 liter) if victim completely conscious/alert. Do
not induce vomiting unless directed to do so by medical personnel. Seek medical attention if
symptoms develop. Provide copy of this MSDS to medical personnel.
Eye Contact: Flush with water to remove. Seek medical attention if irritation or discomfort persists.
Skin Contact: Immediately remove contaminated clothing. Wash skin with mild soap and water. Seek
medical assistance if irritation or discomfort persists. Provide copy of this MSDS to medical
personnel.
Skin Absorption: Not expected to occur. Wash with soap and water.
Inhalation: Remove to fresh air. Seek medical assistance if persistent irritation, severe coughing, or
breathing difficulty occurs. Provide copy of this MSDS to medical personnel.
Note to Physician: This material, if aspirated in to the lungs, may cause chemical pneumonitis.
Treatment of over-exposure should be directed as the control of symptoms and the clinical condition
of the patient.

safety glasses and chemical resistant gloves to minimize exposure.
7. Handling and Storage
Precautions to be Taken In Handling and Storage: Follow standard industrial practices when handling
this product or empty containers. Avoid getting product on skin, eyes, or clothing. If contact with the
product occurs, remove effected clothing and wash with soap and water. Store in a cool, dry, well-
ventilated area away from incompatible materials. Avoid excessive hot or cold temperatures. Keep
containers tightly closed when not in use.
8. Exposure Control Measures, Personal Protection
Personal Protective Equipment:
RESPIRATORY PROTECTION 鈥? Under normal conditions of use, respiratory protection is not required.
If a fog or mist is produced, use NIOSH/MSHA approved respirator with organic vapor absorbing
cartridges. The respirator program must comply with OSHA and ANSI standards.
EYE PROTECTION 鈥? Chemical safety glasses recommended.

PROTECTIVE GLOVES 鈥? Chemically resistant gloves are recommended.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT 鈥? Eye wash station.
WORK/HYGIENE PRACTICES 鈥? Wash hands before eating, drinking, smoking, and at the end of the
shift.
Ventilation:
LOCAL EXHAUST 鈥? If handling results in mist or aerosols, local exhaust ventilation may be needed so
that exposure limits are met.
MECHANICAL (GENERAL) 鈥? Provide general ventilation in processing and storage areas so that
exposure limits are met.
SPECIAL 鈥? None
OTHER 鈥? None
