Conditions Aggravated by Exposure
This material or its emissions may aggravate pre-existing eye disease.
SECTION 4: FIRST AID MEASURES
General
After adequate first aid, no further treatment is required unless symptoms reappear.
Skin
Remove contaminated clothing as needed. Flush with lukewarm water for 15 minutes. Wash skin thoroughly with mild soap
and water. If sticky, use waterless cleaner first. Seek medical attention if ill effect or irritation develops.
Inhalation
If overcome by exposure, remove victim to fresh air immediately. Give oxygen or artificial respiration as needed. Obtain
emergency medical attention.
Eye
Immediately flush the eyes with large amounts of clean low-pressure water for at least 15 minutes, occasionally lifting the
upper and lower lids. If pain or irritation persists, promptly obtain medical attention.
Ingestion
If large quantity swallowed, give lukewarm water (pint/ 1/2 litre) if victim completely conscious/alert. Do not induce vomiting.
Risk of damage to lungs exceeds poisoning risk. Obtain emergency medical attention.
Note to Physician
Treat symptomatically. Treatment of overexposure should be directed at the control of symptoms and the clinical condition
of the patient.

92.2 掳C (197.96 掳F) (SETA)
Auto-Ignition Temperature
~ 269 掳C (516.2 掳F)
Lower Flammable Limit
No Data Available.

MSDS No.: BN0014
Variant: U.S.A.-EN
Material Safety Data Sheet Version No: 1.3
Validation Date: 07/07/2003
DPTB-90
Unsuitable: Do not use solid water stream/may spread fire.
Protection of Firefighters
Protective Equipment/Clothing: Use only approved supplied air or self-contained breathing apparatus operated in
positive pressure mode.
Fire Fighting Guidance: When heated above the flash point, releases flammable vapors. When mixed with air and
exposed to ignition source, vapors can burn in open or explode if confined. Vapors may be heavier than air. May travel long
distances along the ground before igniting and flashing back to vapor source. Fine sprays/mists may be combustible at
temperatures below normal flash point. Fight fire from a safe distance/protected location. Heat may build enough pressure
to rupture closed containers/spreading fire/increasing risk of burns/injuries. Do not use solid water stream/may spread fire.
Burning liquid may float on water. Use water spray/fog for cooling. Avoid frothing/steam explosion. Although water soluble,
may not be practical to extinguish fire by water dilution. Notify authorities immediately if liquid enters sewer/public waters.
Hazardous Combustion Products: Thermal decomposition may produce carbon monoxide and other toxic vapors.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Release Response
Liquids/vapors may ignite. May contaminate water supplies/pollute public waters. Evacuate/limit access. Equip
responders with proper protection extinguish all ignition sources. Stop release; prevent flow to sewers/public waters. Notify
fire and environmental authorities. Restrict water use for cleanup. Slippery walking/spread granular cover or soak up.
Impound/recover large land spill. Contain/collect rapidly to minimize dispersion. Soak up small spill with inert solids; use
suitable disposal containers. On water, material is soluble and may float or sink. Disperse residue to reduce aquatic harm.
Report per regulatory requirements.
SECTION 7: HANDLING AND STORAGE
Handling
For industrial use only. Keep container tightly closed when not in use. Flammable/combustible residue remains after
emptying. Handle empty containers with care. Use only non-sparking tools. Properly ground containers before beginning
transfer. Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair.
Storage
This product will absorb water if exposed to air. Store only in tightly closed, properly vented containers away from heat,
sparks, open flame and strong oxidizing agents. Some plastics/rubbers are attacked by Glycol Ethers/Ether Esters. Store
in properly lined steel/stainless steel to avoid slight discoloration from mild steel/copper. For fixed site operations,
ARCOSOLV products and other propylene glycol ethers with flash points at or below 60 潞C (140 潞F) should be stored under
nitrogen blanketing. Storage under nitrogen atmosphere is recommended to minimize potential for moisture condensation
in the vapor space, and the formation of peroxides.
SECTION 8: EXPOSURE CONTROLS AND PERSONAL PROTECTION
Engineering Controls
No special ventilation is recommended under anticipated conditions of normal use beyond that needed for normal comfort
control.
Personal Protection
Inhalation No occupational exposure limit(s) have been established for this material or its components. Where exposure
through inhalation may occur from use, approved respiratory protection equipment is recommended. A respiratory
protection program that meets OSHA's 29 CFR 1910.134 or ANSI Z88.2 requirements must be followed whenever
workplace conditions warrant respirator use.
Skin Wear chemical resistant gloves such as: Neoprene. Depending on the conditions of use, protective gloves, apron,
boots, head and face protection should be worn.
Eye Use splash goggles when eye contact due to splashing or spraying liquid is possible.

Selection of appropriate personal protective equipment should be based on an evaluation of the performance
characteristics of the protective equipment relative to the task(s) to be performed, conditions present, duration of use, and
the hazards and/or potential hazards that may be encountered during use. Emergency eye wash fountains and safety
showers should be available in the immediate vicinity of any potential exposure. Use good personal hygiene practices.
Wash hands before eating, drinking, smoking, or using toilet facilities. Promptly remove soiled clothing/wash thoroughly
before reuse.
