Section 4 - First Aid Measures
Inhalation: Immediately move victim to fresh air. If victim is not breathing, immediately begin rescue breathing. If heart has
stopped, immediately begin cardiopulmonary resuscitation (CPR). If breathing is difficult, 100 percent humidified oxygen
should be administered by a qualified individual. Seek medical attention immediately.
Eye Contact: Check for and remove contact lenses. If irritation or redness develops, flush eyes with cool, clean, low-pressure
water for at least 15 minutes. Hold eyelids apart to ensure complete irrigation of the eye and eyelid tissue. Do not use eye
ointment. Seek medical attention immediately.
Skin Contact: Remove contaminated shoes and clothing. Flush affected area with large amounts of water. If skin surface is
damaged, apply a clean dressing and seek medical attention. Do not use skin ointments. If skin surface is not damaged, clean
affected area thoroughly with mild soap and water. Seek medical attention immediately.
Ingestion: Do not induce vomiting. If spontaneous vomiting is about to occur, place victim’s head below knees. If victim is
drowsy or unconscious, place on the left side with head down. Never give anything by mouth to a person who is not fully
conscious. Do not leave victim unattended. Seek medical attention immediately.
Note to Physicians: INHALATION: Inhalation overexposure can produce toxic effects. Monitor for respiratory distress. If
cough or difficulty breathing develops, evaluate for upper respiratory tract inflammation, bronchitis and pneumonitis.
Administer supplemental oxygen with assisted ventilation, as required.
This material sensitizes the heart to the effects of sympathomimetic amines. Epinephrine and other sympathomimetic drugs
may initiate cardiac arrhythmias in individuals exposed to this material. Administration of sympathomimetic drugs should be
INGESTION: If ingested, this material presents a significant aspiration and chemical pneumonitis hazard. Induction of emesis
is not recommended. Consider activated charcoal and/or gastric lavage. If patient is obtunded, protect the airway by cuffed

Section 5 - Fire-Fighting Measures
Flash Point: 65 °F (18 °C)
Flash Point Method: TCC
Autoignition Temperature: 450 °F (232 °C)
LEL: 0.9% v/v
UEL: 6.7% v/v
Flammability Classification: NFPA Class – 1B flammable liquid.
Extinguishing Media: SMALL FIRE: Use dry chemicals, carbon dioxide, foam, water fog or inert gas (nitrogen).
LARGE FIRE: Use foam, water fog or water spray. Water fog and spray are effective in cooling containers and adjacent
structures. However, water can cause frothing and/or may not extinguish the fire. Water can be used to cool the external walls
of vessels to prevent excessive pressure, autoignition or explosion. DO NOT use a solid stream of water directly on the fire as
the water may spread the fire to a larger area.
Unusual Fire or Explosion Hazards: Flammable Liquid! This material releases vapors at or below ambient temperatures.
When mixed with air in certain proportions and exposed to an ignition source, its vapor can cause a flash fire. Use only with
adequate ventilation. Vapors are heavier than air and may travel long distances along the ground to an ignition source and flash
back. A vapor and air mixture can create an explosion hazard in confined spaces such as sewers. If container is not properly
cooled, it can rupture in the heat of a fire.
Hazardous Combustion Products: Carbon dioxide, carbon monoxide, smoke, fumes and/or unburned hydrocarbons may be
released in a fire.
Fire-Fighting Instructions: Firefighters must use full bunker gear including NIOSH-approved positive pressure self-contained
breathing apparatus (SCBA) to protect against potential hazardous combustion or decomposition products and oxygen
deficiencies. Evacuate area and fight the fire from a maximum distance or use unmanned hose holders or monitor nozzles.
Cover pooling liquid with foam. Containers can build pressure if exposed to radiant heat; cool adjacent containers with
flooding quantities of water until well after the fire is out. Be aware that burning liquid will float on water. Notify appropriate
authorities if liquid enters sewers or waterways.
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.

Flammable Liquid! Release causes an immediate fire or explosion hazard. A vapor-suppressing foam may be used to reduce
vapors. Eliminate all ignition sources. All equipment used when handling this material must be grounded. Stop the leak if it
can be done without risk. Do not touch or walk through spilled material. Remove spillage immediately from hard, smooth
walking surfaces. Prevent spilled material from entering waterways, sewers, basements or confined area. Absorb or cover with
dry earth, sand or other non-combustible material and transfer to appropriate waste containers. Use clean, non-sparking tools to
collect absorbed material.
For large spills, secure the area and control access. Prevent spilled material from entering sewers, storm drains, other drainage
systems and natural waterways. Dike far ahead of a liquid spill to ensure complete collection. Water mist or spray may be used
to reduce or disperse vapors; but it might not prevent ignition is closed spaces. This material will float on water and its run-off
may create an explosion or fire hazard. In an urban area, cleanup spill as soon as possible; in natural environments, cleanup on
advice from specialists. Pick up free liquid for recycle and/or disposal if it can be accomplished safely with explosion-proof
equipment. Collect any excess material with absorbant pads, sand, or other inert non-combustible absorbent materials. Place
into appropriate waste containers for later disposal. Comply with all laws and regulations.
Section 7 - Handling and Storage
Handling Precautions: A spill or leak can cause an immediate fire or explosion hazard. Keep containers closed and do not
handle or store near heat, sparks or other potential ignition sources. Do not contact with oxidizable materials. Do not breath
vapor. Use only with adequate ventilation and personal protection. Never siphon by mouth. Avoid contact with eyes, skin and
clothing. Prevent contact with food and tobacco products. Do not take internally. KEEP OUT OF REACH OF CHILDREN.
Storage Requirements: Store and transport in accordance with applicable laws. Keep containers tightly closed and store in a
cool, dry, well-ventilated place, plainly labeled and out of closed vehicles. Keep away from ignition sources. Ground all
equipment containing this material. Containers should be able to withstand pressures expected from warming and cooling in
storage. This flammable liquid should be stored in a separate safety cabinet or room.

none estab.
350 ppm
none estab.
none estab.
Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapor
and mists below the applicable workplace exposure limits of 300 ppm. All electrical equipment should comply with the
National Electric Code. An emergency eye wash station and safety shower should be located near workstation.
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs. Local
exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source.
Administrative Controls:
Respiratory Protection: Odor is not an adequate warning for potentially hazardous air concentrations. For unknown vapor
concentrations, use a positive-pressure, pressure-demand, self-contained breathing apparatus (SCBA), especially when entering
a confined space or where the oxygen concentrations may be reduced because of an accumulation of vapors. For known vapor
concentrations above the occupational exposure guidelines (see Section 2), use a NIOSH-approved organic vapor respirator, if
adequate protection is provided. Respirators should be used in accordance with OSHA requirements (29 CFR 1910.134).
Eye Protection: Safety glasses equipped with side shields are recommended as minimum protection in industrial settings.
Safety glasses/goggles should be worm during transfer operations or when there is a likelihood of misting, splashing or
spraying of this material. Suitable eye wash water should be readily available.
Hand Protection: Avoid skin contact. Permeation resistant gloves (that meet ANSI/ISEA 105-2005) recommended. Wash
hands with plenty of mild soap and water before eating, drinking, smoking, use of toilet facilities or leaving work.
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.

Section 12 - Ecological Information
Ecotoxicity: This mixture contains components that are potentially toxic to freshwater and saltwater ecosystems.
Environmental Fate: This mixture will normally float on water with its lighter components evaporating rapidly. In stagnant or
slow-flowing waterways, a hydrocarbon layer can cover a large surface area. As a result, this covering layer might limit or
eliminate natural atmospheric oxygen transport into the water. With time, if not removed, oxygen depletion in the waterway
might be enough to cause a fish kill or create an anaerobic environment. This coating action can also be harmful or fatal to
plankton, algae, aquatic life and water birds.
