3 HAZARDS IDENTIFICATION

Emergency Overview
Pale straw liquid with amine odor

WARNING!
CAUSES EYE IRRITATION.


Potential Health Effects

Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, it is considered to be slightly toxic if swallowed, practically non-toxic if absorbed through
skin, severely irritating to eyes and practically non-irritating to skin.

4 FIRST AID MEASURES

IF IN EYES, immediately flush with plenty of water for at least 15 minutes. Get medical attention.

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, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.

IF INHALED, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.


5 FIRE FIGHTING MEASURES

Fire and Explosive Properties
Auto-Ignition Temperature 770 F (410 C)
Flash Point 240 F Flash Point Method PMCC
Flammable Limits- Upper 8.8
1.4
Lower
Extinguishing Media
Use water spray, carbon dioxide, foam or dry chemical.

Fire Fighting Instructions
Fire fighters and others who may be exposed to products of combustion should wear full fire fighting turn out
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:
Oxides of carbon and nitrogen

6 ACCIDENTAL RELEASE MEASURES

In Case of Spill or Leak
Small spills may be flushed away with large volume of water. 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
Avoid contact with eyes.
Wash thoroughly after handling.

Emptied container retains vapor and product residue. Observe all labeled safeguards until container is
cleaned, reconditioned or destroyed.

Storage
This material is not hazardous under normal storage conditions; however, material should be stored in

7 HANDLING AND STORAGE

closed containers, in a secure area to prevent container damage and subsequent spillage.



8 EXPOSURE CONTROLS / PERSONAL PROTECTION

Engineering Controls
Investigate engineering techniques to reduce exposures. Provide ventilation if necessary to minimize
exposure. Dilution ventilation is acceptable, but local mechanical exhaust ventilation preferred, if practical, at
sources of air contamination such as open process equipment.

Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment
immediately 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
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 a 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.

11 TOXICOLOGICAL INFORMATION

Toxicological Information
Data on this material and/or its components are summarized below.

Single exposure (acute) studies indicate:
Oral - Slightly Toxic to Rats (LD50 4,780 mg/kg)
Dermal - Practically Non-toxic to Rabbits (LD50 6,300 mg/kg)
Inhalation - No deaths in rats following exposure to saturated vapor for 8-hours
Eye Irritation - Severely Irritating to Rabbits (59/110)
Skin Irritation - Practically Non-irritating to Rabbits (4-hr exposure, 0.2/8.0)
No skin allergy was observed in guinea pigs following repeated exposure. Severe irritation, but no systemic
effects, were observed following repeated application to the skin of rats. No birth defects were observed in the
offspring of rats following application to the skin during pregnancy, even a doses which produced adverse
effects on the mothers. No genetic changes were observed in tests using bacteria or animals.
