4. FIRST AIDMEAST]RES
EYES: Immediately flush with plenty of water, After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Get
medical advice/attention if irritation develops.
SKIN: Immediately wash skin with soap and plenty of water. Remove contaminated clothing. Get medical advice/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 *re
patient is conscious, wash out mouth with water. Never give anything by mouth to an unconscious person.
INHAI-ATION: Remove to fresh air. Seek medical advice/attention if breathing becomes difficult or if respiratory irritation develops.
NOTES TO PIfYSICIAN: Symptomatic and supportive therapy as needed. Following severe exposure medical follow-up should be monitored
for at least 48 hours.
5. FIRE FIGHTING MEAST]RES
EXTINGLIISHING MEDIA: Carbon dioxide, dry chemical, or alcohol-resistant foam.
HAZARDOUS COMBUSTION PRODUCTS: Carbon monoxide, carbon dioxide, formaldehyde, and silicon dioxide.
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 EQLIIPMENT: Firefighters should wear positive pressure self-contained breathing apparatus (S CBA) and consider use of
unmanned hose holders or monitor nozzles for fighting large fires.
6. ACCIDENTAL RELEASE MEASURES
SPILL AllD LEAK PROCEDURBS: 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 fiom entering sewers or waterways

TC-5030 PART A
Neutralize small spills with a decontaminant.
LARGE SPILL: Contain and absorb lmge spills onto an inert, non-flammable adsorbent camier (such as earth or sand). Shovel into open{op
drums or plastic bags for further decontamination, if necessary. Wash the spill area clean with a liquid decontaminant. Remove and properly
dispose of residues. Notifo applicable govemment authorities if release is reportable. (See CERCLA in Section 15).
EN4R ONMEN TAL PRECA UTIONS
WATER SPILL: Do not discharge into drains, sutface waters, or groundwater.
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. HAIDLING AND STORAGE
GENERAL PROCEDURES: Avoid contact with eyes, skin and clothing. Use only with adequate ventilation. Avoid breattring 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 industriaVmanufacturing 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 (l 8-27’C)
SHELF LIFE: 12 months from date of shipment under manufacturers recommended storage conditions.

E)POSURE LIMITS
ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation, or other engineering controls to control airbome levels below
recomm ended 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 287.1 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 cartidge 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 respiratoruse (29 CFR 1910. 134).
PROTECTfVE CLOTHING: Protective clothing should be selected and used in accordance with “Guidelines forthe Selection of Chemical
Protective Clothing” published by ACGIH.
WORK HYGIEMC 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.
