3 HAZARDS IDENTIFICATION
Emergency Overview
Water white liquid with gas-like odor
DANGER!
EXTREMELY FLAMMABLE LIQUID AND VAPOR. VAPOR MAY CAUSE FLASH FIRE.
MAY CAUSE EYE IRRITATION.
MAY CAUSE RESPIRATORY TRACT IRRITATION.
MAY CAUSE NAUSEA, HEADACHE OR DIZZINESS.
Potential Health Effects
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. This
material has a strong objectionable odor that may cause nausea, headache, or dizziness. Vapor may be irritating to the
eyes, nasal and respiratory tract and, with extreme overexposure, may cause a sense of coldness at the extremities,
rapid heartbeat, cyanosis and respiratory paralysis.

4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water. Get medical attention if irritation persists.
IF ON SKIN, immediately flush with plenty of water. Remove contaminated clothing and shoes. Get medical
attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
IF SWALLOWED, induce vomiting as directed by medical personnel. Get medical attention. NEVER GIVE
ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If breathing is difficult, get medical attention.

Flash Point <0 F Flash Point Method TCC
Flammable Limits- Upper NE
NE
Lower
Extinguishing Media
Use water spray, carbon dioxide, foam or dry chemical.
Fire Fighting Instructions
Water may be ineffective. Use water spray or water fog to cool surrounding surfaces and prevent fire damage
or rupture of containers. Fire fighters and others who may be exposed to products of combustion should wear
full fire fighting gear (full Bunker Gear) and self-contained breathing apparatus (pressure demand NIOSH
approved or equivalent). Fire fighting equipment should be thoroughly decontaminated after use.
Fire and Explosion Hazards
When burned, the following hazardous products of combustion can occur:
Hydrogen sulfide
Oxides of carbon
Sulfur oxides
Vapors can travel to a source of ignition and flash back.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Extinguish or turn off ignition or combustion sources. Contain spill. Stop leak at source if this can be done
safely. Ventilate area only if odor control is not an issue. Nonessential personnel should leave the area until
cleanup is completed. Cover spill area with closed-cell foam to reduce odors (use of Aqueous Film Forming
Foam (AFFF) with polymeric layer is acceptable). If foam is unavailable, absorb spill with liquid-binding
material (e.g. diatomaceous earth, saw dust universal binder) and deodorize residue on ground with 3-10%
hydrogen peroxide. If spill is contained within a large containment area, add 5% bleach solution (sodium
hypochlorite) in a 50 parts bleach solution to one part product dilution ratio. Swimming pool chemicals
(hypochlorite compounds) work effectively in deodorizing product. If these are applied to product, the crystals
must be accompanied by sufficient water of dilution so that the considerable heat of reaction will be
absorbed. Enzyme or bacteria based deodorizers are also acceptable for use. Place waste materials into
Department of Transportation (DOT)-approved drums for disposal. Where practicable wash area down with
water. Keep concentrate and wash water from entering sewers or waterways. Consult a regulatory specialist

to determine appropriate state or local reporting requirements, for assistance in waste characterization and/or
hazardous waste disposal and other requirements listed in pertinent environmental permits.
7 HANDLING AND STORAGE
Handling
Keep away from heat, sparks and flame.
Keep container closed.
Use only with adequate ventilation.
Avoid contact with eyes.
Wash thoroughly after handling.
CONTAINER HAZARDOUS WHEN EMPTY. Emptied container retains vapor and product residue. Follow
labeled warnings even after container is emptied. RESIDUAL VAPORS MAY EXPLODE ON IGNITION. DO
NOT CUT, DRILL GRIND OR WELD ON OR NEAR THIS CONTAINER. Improper disposal or reuse of this
container may be dangerous and/or illegal.
Storage
Store in well ventilated area away from heat and sources of ignition such as flame, sparks and static
electricity. Ensure that all storage and handling equipment is properly rated, grounded and installed to satisfy
electrical classification requirements. Static electricity may accumulate and create a fire hazard. All storage
containers, including containers such as drums, cylinders and IBC鈥檚, must be bonded and grounded during
filling and emptying operations. Store away from oxidizers and reactive materials. Keep container tightly
closed. Observe all federal, state and local regulations and National Fire Protection Association (NFPA)
Codes which pertain to the specific local conditions of storage and use, including OSHA 29 CFR 1910.106
and NFPA 30, 70, 77, and 497.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures. Provide ventilation if necessary to minimize
exposures. If practical, use local mechanical exhaust ventilation at sources of air contamination such as
open process equipment. Consult ACGIH ventilation manual or NFPA Standard 91 for design of exhaust
systems.
Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.
Skin Protection
Minimize skin contamination by following good industrial hygiene practice. Wearing rubber gloves is
recommended. Wash hands and contaminated skin thoroughly after handling.
Respiratory Protection
Avoid breathing vapor or mist. Where airborne exposure is likely, use NIOSH approved respiratory
protection equipment appropriate to the material and/or its components. If exposures cannot be kept at a
minimum with engineering controls, consult respirator manufacturer to determine appropriate type equipment
for given application. Observe respirator use limitations specified by NIOSH or the manufacturer. For
emergency and other conditions where there may be a potential for significant exposure, use an approved full

face positive-pressure, self-contained breathing apparatus or positive-pressure airline with auxiliary self-
contained air supply. Respiratory protection programs must comply with 29 CFR 搂 1910.134.
Airborne Exposure Guidelines for Ingredients
The components of this product have no established Airborne Exposure Guidelines
-Only those components with exposure limits are printed in this section.
-Skin contact limits designated with a "Y" above have skin contact effect. Air sampling alone is insufficient to accurately quantitate
exposure. Measures to prevent significant cutaneous absorption may be required.
-ACGIH Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic reactions.
-WEEL-AIHA Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic skin reactions.

Inhalation - Practically Non-toxic to Rats (4-hr LC50 >18.44 mg/l)
Eye Irritation - Practically Non-irritating to Rabbits
DOT Skin Corrosion - Non-corrosive to Rabbits (4-hr exposure)
Acute effects in rats during exposure to sublethal vapor concentrations of 18.44 mg/l or less for 4-hours were
attributed to the irritant nature of the vapors.
