organo-metallic compounds.

HAZARDOUS DECOMPOSITION OR BYPRODUCTS: Carbon dioxide, carbon monoxide, and

other toxic gases.

==================== SECTION VI - HEALTH HAZARD DATA =======================

INHALATION HEALTH RISKS AND SYMPTOMS OF EXPOSURE: This material is a potential

respiratory sensitizer. Effects vary among individuals and may include

headache, dizziness, nausea, irritation of the nose, throat, and respiratory

tract, and incoordination. Severe overexposure may produce anesthesia or

unconsciousness.

SKIN AND EYE CONTACT HEALTH RISKS AND SYMPTOMS OF EXPOSURE: May cause eczema or

allergic skin reaction. Long term contact has the potential for causing

chemical burns, necrosis, and scar tissue formation. Eye contact may cause

irritation, redness, and tearing, and blurred vision. Skin contact may cause

irritation and redness. Long term skin exposure may dry and defat the skin,

causing cracking, and in severe cases, dermatitis.

INGESTION HEALTH RISKS AND SYMPTOMS OF EXPOSURE: Ingestion can cause

gastrointestinal irritation, vomiting, nausea, and diarrhea.

HEALTH HAZARDS (ACUTE AND CHRONIC): Repeated or prolonged contact with skin may

cause eczema, dermatitis, sensitization, or allergic skin reactions. CORROSIVE!

May cause chemical burns to eyes and skin.

CARCINOGENICITY: NTP: No IARC MONOGRAPHS: No OSHA REGULATED: No

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: May aggravate pre-existing

skin conditions such as eczema, dermatitis, or cause allergic response.

Overexposure to solvent fumes may aggravate anesthesia, respiratory tract

disease or pre-existing lung disorders, nausea, and vomiting.

EMERGENCY AND FIRST AID PROCEDURES: INHALATION OVEREXPOSURE: Remove person to

fresh air, If breathing stops, apply artificial respiration and seek immediate

medical attention. NOTE: Use supplied-air respirator for rescue in enclosed

areas. EYE CONTACT: Flush with large amounts of tepid water for at least 15

minutes, get medical attention. INGESTION: Do not induce vomiting, if aspirated

material can cause chemical pneumonitis or pulmonary edema. Drink 2 glasses of

milk or water to dilute and contact physician or poison center. SKIN: Wash with

soap and water, avoid repeated contact.

=========== SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE ============

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Dike to prevent entry

into sewers or surface waters. Recover free liquid by shoveling into container,

or add absorbant such as sand or earth to spill and sweep up. Provide

ventilation, wear a respirator. Notify proper authorities if spill contaminates

land or waterways.

WASTE DISPOSAL METHOD: Dispose of in chemical landfill or incinerate assuring

conformity to all applicable local, state, and federal governing regulations.

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Do not expose to direct sun or

freezing temperatures, store inside away from extreme temperature variations.

Protect containers from physical damage. Keep containers tightly closed when

not in use. Do not inhale vapors or mists, use with adequate ventilation and

wear a respirator. Do not store with food or animal feed.

OTHER PRECAUTIONS: Do not cut, weld, grind, drill, solder, or braze on or near

containers whether full or empty. Do not reuse containers without professional

reconditioning and testing. Do not remove warning labels from containers.

===================== SECTION VIII - CONTROL MEASURES ======================

RESPIRATORY PROTECTION: Using this product in poorly ventilated areas may

require the use of a respirator. Use Mine Safety Appliance respirator #448849

with organic vapor cartridge and mist filter (or equivalent) if air monitoring

demonstrates that the concentration of listed hazardous materials exceeds the

recommended TLV's. In enclosed areas where ventilation is not used, wear a Mine

Safety Appliance #475217 pressure/demand air-supplied respirator or equivalent.

VENTILATION: Use good general mechanical ventilation and local exhaust adequate

to reduce the concentration of vapors or mists of the listed hazardous materials

to below the Threshold Limit Value(s) and the Lower Explosion Limit.

Ventilation equipment must be explosion proof.

PROTECTIVE GLOVES: Use of gloves is recommended, use chemically resistant type.

EYE PROTECTION: Use is recommended, use splash goggles or full face shields as

necessary.

OTHER PROTECTIVE CLOTHING: Use impervious apron or coveralls to prevent

contaminating street clothes which may result in prolonged exposure. The use of

head caps or helmets is recommended.

WORK AND HYGIENIC PRACTICES: Eye washes and safety showers in the workplace are

recommended. Practice good industrial hygiene when using this product: After

using this product, do not smoke or eat until washing thoroughly. Remove

saturated clothing or shoes at once and launder before reuse.
