Potential Health Effects PPE??
Primary Entry Routes: Skin contact, skin absorption, eye contact, inhalation and ingestion. ?Sec. 8
Target Organs:
Acute Effects
Inhalation: May cause breathlessness, coughing, chest discomfort, reduced pulmonary function, and irritation of nasal
passages.
Eye: May cause irritation, tearing, reddening, swelling and stinging of the eyes.
Skin: May cause irritation (tearing, reddening, swelling, rash or blistering); skin sensitization may develop in some individuals.
Ingestion: May cause irritation to mouth, stomach, and digestive tract.
Carcinogenicity: IARC, NTP, and OSHA do not list this product as a carcinogen.
Chronic Effects: Repeated overexposure may cause sensitization (chest tightness, coughing, shortness of breath, or asthmatic
attack) in certain individuals that can lead to permanent lung damage. Prolonged skin contact can cause reddening, swelling,
rash or blistering, which can develop in some persons after contact with only a small amount of liquid. Prolonged vapor contact
with eyes may cause conjunctivitis.
Section 4 - First Aid Measures
Inhalation: Remove victim to fresh air and provide oxygen if breathing is difficult. Give artificial respiration if not breathing.
Get medical attention immediately.
Eye Contact: Immediately flush eyes with running water for at least 15 minutes. Get medical attention.
Skin Contact: Immediately flush skin with running water and remove contaminated clothing. Wash exposed area with soap and
water. Get medical attention.
Ingestion: Do not induce vomiting. Get medical attention immediately.
Special Precautions/Procedures: Whenever possible, remove the worker from the source of contamination.

UEL: 7.0%v/v (estimated)
Flammability Classification: Division 2
Extinguishing Media: In case of fire, use dry chemical, carbon dioxide, or foam. Water may not be effective as an
extinguishing agent. Water fog or spray may be used to provide a smothering effect on fire and to cool fire-exposed containers
and surrounding combustibles. Do not use a solid stream of water because it can scatter and spread the fire.
Unusual Fire or Explosion Hazards: Combustible liquid-Keep away from sparks and open flame.
Hazardous Combustion Products: Toxic gases or vapors, such as carbon monoxide or carbon dioxide, may be released in a
fire.
Fire-Fighting Instructions: SCBA recommended; smother to exclude air. Handle as an oil fire, Class B fire procedures.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing
apparatus (SCBA) with a full-face piece operated in pressure-demand or positive-pressure mode.
Section 6 - Accidental Release Measures
Spill /Leak Procedures: Remove all sources of ignition. Avoid breathing vapors. Use self-contained breathing apparatus in
enclosed area. Ventilate area. Contain and remove with inert absorbent materials and non-sparking tools.
Large Spills
Containment: For large spills, dike far ahead of liquid spill for later disposal. Do not release into sewers or waterways.
Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).
Section 7 - Handling and Storage
Handling Precautions: Use away from all sources of heat, flame, or sparks. Do not smoke while using. Wash with soap and
water before eating or drinking. Launder contaminated clothing. KEEP OUT OF REACH OF CHILDREN.
Storage Requirements: Keep containers cool, dry, and store way from all sources of heat, flame, and sparks. Keep containers
tightly closed and store with adequate ventilation. Do not pressurize, cut, weld, or grind the containers or empty containers,
which may contain residual product and solvent vapors that may ignite explosively.
Section 8 - Exposure Controls / Personal Protection
Engineering Controls: Do not use in enclosed areas without proper ventilation. General and local exhaust ventilation must be
sufficient to control vapor concentrations and keep the vapor concentration below PEL.
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs
(Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at
its source.
Administrative Controls:
Respiratory Protection: Approved NIOSH respirator recommended if working in very high mist or vapor concentrations.
Protective Clothing/Equipment: Impermeable gloves recommended. Safety glasses or goggles recommended. Industrial shoes
to protect feet from contact with cleaner. Long sleeves, long trousers to protect skin from adhesive contact.
Safety Stations: Make emergency eyewash stations, safety/quick-drench showers, and washing facilities available in work area.
Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this
material from your shoes and clean personal protective equipment.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before
eating, drinking, smoking, using the toilet, or applying cosmetics.
