3. HAZARDS IDENTIFICATION
POTENTIAL HEALTH EFFECTS:
Eye: Contact may cause mild eye irritation including stinging, watering, and redness.
Skin: Contact may cause mild skin irritation including redness and burning. No harmful effects from skin
absorption have been reported.
Inhalation (Breathing): No information available. Studies by other exposure routes suggest a low
degree of toxicity by inhalation.
Ingestion (Swallowing): No harmful effects reported from ingestion.
Signs and Symptoms: Effects of overexposure may include irritation of the nose, throat and digestive
tract, headaches, coughing, nausea, vomiting, and transient disorientation.
Cancer: Inadequate evidence available to evaluate the cancer hazard of this material.
Target Organs: No data available.
Developmental: Inadequate evidence available for this material.
Pre-Existing Medical Conditions: None known.

4. FIRST AID MEASURES
Eye: If irritation or redness develops, move victim away from exposure and into fresh air. Flush eyes with
clean water. If symptoms persist, seek medical attention.
Skin: Remove contaminated shoes and clothing and cleanse affected area(s) thoroughly by washing
with mild soap and water. If irritation or redness develops and persists, seek medical
attention.
Inhalation (Breathing): If respiratory develop, move victim away from source of exposure and
into fresh air. If symptoms persist, seek medical attention. If victim is not breathing, clear
airway and immediately begin artificial respiration. If breathing difficulties develop, oxygen
should be administered by qualified personnel. Seek immediate medical attention.
Ingestion (Swallowing): First aid is not normally required; however, if swallowed and symptoms
develop, seek medical attention.
5. FIRE FIGHTING MEASURES
Flammable Properties: Flash Point: None to boiling
OSHA Flammability Class: Not applicable
LEL/UEL: No data
Autoignition Temperature: No data
Unusual Fire & Explosion Hazards: Closed containers exposed to extreme heat can rupture due
to pressure buildup.
Extinguishing Media: Use extinguishing agent suitable for type of surrounding fire.
Fire Fighting Instructions: For fires beyond the incipient stage, emergency responders in the
immediate hazard area should wear bunker gear. When the potential chemical hazard is
unknown, in enclosed or confined spaces, or when explicitly required by DOT, a self-
contained breathing apparatus should be worn. In addition, wear other appropriate
protective equipment as conditions warrant (see Section 8). Isolate immediate hazard area
and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk.
Move undamaged containers from immediate hazard area if it can be done with minimal
risk. Water spray may be useful in minimizing or dispersing vapors. Cool equipment exposed
to fire with water, if it can be done with minimal risk.

6. ACCIDENTAL RELEASE MEASURES
Stop the source of the release if it can be done without risk. Immediately isolate the hazard area
and restrict access to authorized personnel only. Wear appropriate protective equipment
including respiratory protection as conditions warrant (see Section 8). To prevent spilled material
from entering sewers, storm drains or natural watercourses, contain material with a dike or with
appropriate absorbent materials such as sand, clay, soil or commercially available absorbent.
Place reclaimed liquid and absorbent into recovery or salvage drums for disposal. Refer to
Section 12 for appropriate disposal.
7. HANDLING AND STORAGE
Handling: Do not enter confined spaces such as tanks or pits without following proper entry
procedures such as ASTM D-4276 and 29CFR 1910.146. The use of appropriate respiratory
protection is advised when concentrations exceed any established exposure limits (see
Section 2 and 8). Wash thoroughly after handling. Do not wear contaminated clothing or
shoes. Use good personal hygiene practice.
Storage: Keep container(s) tightly closed. Do not heat or contact with strong oxidizers. Use and
store this material in cool, dry, well- ventilated areas. Do not store at temperatures below
40癋. Store only in approved containers. Keep away from any incompatible material (see
Section 10). Protect container(s) against physical damage.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls: If current ventilation practices are not adequate to minimize exposure,
additional ventilation or exhaust systems may be required.
Personal Protective Equipment (PPE):
Respiratory: Respiratory protection is not usually required. If significant spray or mist
occurs, wear a NIOSH approved or equivalent dust respirator.
Skin: The use of gloves impermeable to the specific material handled is advised to
prevent skin contact, possible irritation, and absorption (see glove manufacturer for
information on permeability)
.
Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, or
injury is recommended. Depending on conditions of use, a face shield may be
necessary.
Other Protective Equipment: A source of clean water should be available in the work
area for flushing eyes and skin. Impervious clothing should be worn as needed.

12. DISPOSAL CONSIDERATIONS
This material, if discarded as produced, is not a RCRA "listed" or "characteristic" hazardous waste.
Use resulting in chemical or physical change or contamination may subject it to regulation as a
hazardous waste. Along with properly characterizing all waste materials consult state and local
regulations regarding the proper disposal of this material.
Disposal: If this product becomes a waste, it does not meet the criteria of a hazardous waste as
defined under the Resource Conservation and Recovery Act (RCRA) 40 CFR 261, since it does not
have the characteristics of Subpart C, nor is it listed under Subpart D. As a non-hazardous liquid
waste, it should be solidified with stabilizing agents such as sand, fly ash, or clay absorbent, so that
no free liquid remains before disposal to an industrial waste landfill.
