Potential Health Effects PPE鈥?
Primary Entry Routes: Skin contact, skin absorption, eye contact, inhalation, ingestion. 鈥燬ec. 8
Acute Effects
Inhalation: Aspiration into lungs can cause chemical pneumonitis, which can be fatal.
Eye: irritation
Skin: irritation
Ingestion: Ingestion can cause gastrointestinal irritation, vomiting and diarrhea.
Carcinogenicity: IARC, NTP, and OSHA do not list this product as a carcinogen.
Medical Conditions Aggravated by Long-Term Exposure: Respiratory symptoms associated with pre-existing lung disorders, skin
allergies, and pre-existing heart disorders may be aggravated by exposure to this material.
Chronic Effects: Moderate irritation of skin, eyes, and mucous membranes of upper respiratory tract on prolonged/repeated contact.
Dermatitis and defatting of skin. Overexposure may result in headache, dizziness, fatigue, nausea, possible unconsciousness and even
asphyxiation. Chronic exposure may cause reversible kidney and liver injury. Reports have associated repeated and prolonged
occupational overexposure to solvents with permanent brain and nervous system damage.
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.
After first aid, get appropriate in-plant, paramedic, or community medical support.
Special Precautions/Procedures: Whenever possible, remove the worker from the source of contamination.

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: Flammable. Store and use away from all sources of heat, flame, or sparks. Do not smoke while
applying. Vapors are heavier than air and may travel along ground or may be moved by ventilation and ignited by pilot lights, other
flames, sparks, heaters, smoking, electrical motors, static discharge, or other ignition sources at locations distant from material
handling point and flash back. All containers should be grounded when material is transferred.
Hazardous Combustion Products: Carbon Monoxide and Carbon Dioxide
Fire-Fighting Instructions: This product contains solvents that are dangerous fire and explosion hazards when exposed to heat or
flame. Fire fighters should wear self-contained breathing apparatus and full protective clothing with a full face piece operated in the
positive pressure demand mode.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products (fumes, smoke, carbon monoxide, and
carbon dioxide), 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.
Small Spills: For small liquid spills, take up with sand or other noncombustible absorbent material and place into closed containers for
later disposal.
Large Spills: For large spills, dike far ahead of liquid spill for later disposal. Do not release into sewers or waterways.
Regulatory Requirements: This material is considered to be a hazardous under RCRA. 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. Handling equipment must be
grounded to prevent sparking. Handle with non-sparking tools. Wash with soap and water before eating , drinking, or smoking.
Launder contaminated clothing. KEEP OUT OF REACH OF CHILDREN.
Storage Requirements: Keep containers in a cool, dry, well-ventilated area away from all sources of heat, flame, and sparks. Store at
60-95oF and out of sun. Keep containers tightly closed when not in use. 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 explosion-proof 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.
Respiratory Protection: Approved NIOSH respirator must be used if vapor concentration is 50 ppm or above.
Protective Clothing/Equipment: Long sleeves, long trousers to protect skin from sealant contact. Hycron or equivalent solvent
permeation resistant gloves recommended. Protective glasses or goggles recommended, Industrial boots to protect feet from sealant
contact. Protective skin creams or emollients useful.
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.
