4. FIRST AID MEASURES
EYES: Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes.
Get immediate medical attention.
SKIN: Immediately wash skin with soap and plenty of water. Remove contaminated clothing. Get medical attention if irritation or rash
develops. Wash clothing before reuse.
INGESTION: If swallowed, call a physician immediately. Do not induce vomiting unless directed to do so by medical personnel. Provided the
patient is conscious, wash out mouth with water. Never give anything by mouth to an unconscious person.
INHALATION: Remove to fresh air. Seek medical attention if breathing becomes difficult or if respiratory irritation develops.
NOTES TO PHYSICIAN: Symptomatic and supportive therapy as needed. Following severe exposure medical follow-up should be
monitored for at least 48 hours.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Water spray, carbon dioxide, dry chemical, or foam.
HAZARDOUS COMBUSTION PRODUCTS: Carbon monoxide, carbon dioxide, and nitrogen oxides.
FIRE FIGHTING PROCEDURES: Cool fire exposed containers with water spray. Remove containers from the fire area if possible. Do not
release runoff from fire control methods to sewers or waterways.
FIRE FIGHTING EQUIPMENT: Firefighters should wear positive pressure self-contained breathing apparatus (SCBA) and consider use of
unmanned hose holders or monitor nozzles for fighting large fires.
6. ACCIDENTAL RELEASE MEASURES
SMALL SPILL: Evacuate the area. Clean-up should only be performed by trained personnel. People dealing with a major spill should wear
full protective clothing including appropriate respiratory protection. Prevent product spill from entering sewers or waterways. Neutralize
small spills with a decontaminant.
LARGE SPILL: Contain and absorb large spills onto an inert, non-flammable adsorbent carrier (such as earth or sand). Shovel into open-top
drums or plastic bags for further decontamination, if necessary. Wash the spill area clean with a liquid decontaminant. Remove and properly
dispose of residues. Notify applicable government authorities if release is reportable. (See CERCLA in Section 15).
ENVIRONMENTAL PRECAUTIONS
WATER SPILL: Do not discharge into drains or rivers.
GENERAL PROCEDURES: Refer to section 8 of SDS for personal protection details.
RELEASE NOTES: Composition and extent of any spill should be evaluated against local regulations and reported to the proper agencies, if
necessary.
7. HANDLING AND STORAGE
Page 2 of 6
TC-277 PART B

GENERAL PROCEDURES: Avoid contact with eyes, skin and clothing. Use only with adequate ventilation. Avoid breathing vapor over
open containers. Avoid open container exposure to damp air. Avoid breathing aerosols, mists, and vapors.
HANDLING: Use appropriate personal protective equipment as specified in Section 8. Handle in a well ventilated area. Handle and use in a
manner consistent with good industrial/manufacturing techniques and practices.
STORAGE: Store in a dry and well-ventilated place, away from excessive heat, in original or similar container. Avoid unnecessary contact.
Protect from freezing. Containers should be tightly sealed to prevent contamination with foreign materials.
STORAGE TEMPERATURE: 65-80 F (18-27 C)
SHELF LIFE: 6 months from date of shipment under manufacturers recommended storage conditions.

OSHA TABLE COMMENTS:
1. NIOSH REL
ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels
below recommended exposure limits.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Safety goggles or glasses are recommended. Plastic face shields should be used for complete face protection to protect
against possible splashing or spraying of material. ANSI Z87.1 or approved equivalent.
SKIN: Chemical-resistant gloves and chemical goggles, face-shield, and synthetic apron or coveralls should be used to prevent contact with
eyes, skin, or clothing. Wear nitrile or neoprene gloves. Chemical resistant gloves lined with polyethylene offer maximum protection.
RESPIRATORY: Exhaust ventilation recommended. An organic vapor cartridge or fresh air supplied respirator (NIOSH approved) may be
necessary for certain applications. Consider the type of application, environmental concentrations, and other materials being used
concurrently when determining respirator use and selection. Observe OSHA regulations for respirator use (29 CFR 1910.134).
PROTECTIVE CLOTHING: Protective clothing should be selected and used in accordance with ‘Guidelines for the Selection of Chemical
Protective Clothing’ published by ACGIH.
WORK HYGIENIC PRACTICES: Contaminated clothing should be changed and washed before reuse. Eating, drinking and smoking in
immediate work area should be prohibited. Wash hands before eating.
OTHER USE PRECAUTIONS: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Training is important. Follow all label precautions.
