================== SECTION 3 - HEALTH HAZARDS IDENTIFICATION ===================

PRIMARY ROUTES OF EXPOSURE:

Skin contact, eye contact, and inhalation.

EFFECTS OF ACUTE EXPOSURE:

EYES: Contact with eyes may cause irritation including burning, watering, and redness.

SKIN: Contact may cause mild skin irritation including redness, burning, and drying and cracking of skin.      Continued exp

may develop into dermatitis.    Solvents can penetrate the skin and cause systematic effects similar to those under

inhalation symptoms.

INHALATION: High vapor concentrations are irritating to the eyes and respiratory tract, may cause headaches,

dizziness, anesthesia, asthma, drowsiness, unconsciousness, and other central nervous system effects, and possibly

death.

INGESTION: Can cause gastrointestinal irritation, nausea, vomitting and diarrhea.   Small amounts aspirated into the

respiratory system during ingestion or vomiting may cause mild to severe pulmonary injury.





CHRONIC HEALTH EFFECTS:

Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous

system damage (Sometimes referred to as Solvent or Painter's Syndrome). Intentional misuse by deliberately

concentrating and inhaling this material may be harmful or fatal. Chronic exposure may also cause damage to the

respiratory system, lungs, eyes, skin, gastrointestinal tract, liver, spleen and kidneys. Repeated skin contact may

cause persistant irritation or dermatitis.

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE:

Conditions aggrevated by exposure may include skin disorders, respiratory (asthma-like) disorders, and pre-existing

liver or kidney conditions.





=========================               SECTION 4 - FIRST AID MEASURES ======================

IF ON SKIN: Thoroughly wash exposed area with soap and water. Remove contaminated clothing. Launder contaminated

clothing before re-use. If irritation develops and persists, seek medical attention.

IF IN EYES: Flush with large amounts of water for 15 minutes, lifting upper and lower lids occasionally. If symptoms

persist, seek medical attention.

If SWALLOWED: Do not induce vomiting. Immediately administer 1-2 glasses of water and contact a physician, hospital

emergency room, or poison control center for further advice. Keep person warm, quiet and seek immediate medical

attention. Aspiration of material into lungs can cause severe lung damage. VOMITING CAN CAUSE CHEMICAL PNEUMONITIS

WHICH CAN BE FATAL.

INHALATION: Move affected individual to fresh air. If breathing is difficult, qualified personnel should administer

oxygen. If breathing has stopped give artificial respiration. If respiratory symptoms develop or persist, seek medical

attention.

================= SECTION 5 - FIRE AND EXPLOSION HAZARD DATA ===================

FLASH POINT: 110 F                                           METHOD USED: TCC

FLAMMABLE LIMITS IN AIR BY VOLUME- LOWER: 1                                     UPPER: 7

EXTINGUISHING MEDIA:

Foam, CO2, or dry chemical is recommended.     Water spray is recommended to cool or protect exposed materials or

structures.





SPECIAL FIREFIGHTING PROCEDURES:

Persons exposed to products of combustion should wear self-contained breathing apparatus and full protective equipment.

Isolate danger area, keep unauthorized personnel out. Water may be ineffecive for extinguishment, unless used under

favorable conditions by experienced fire fighters. Carbon dioxide can displace oxygen, exercise caution when using CO2

in confined areas.





UNUSUAL FIRE AND EXPLOSION HAZARDS:

Vapors may be ignited by heat, sparks, flames, or other sources of ignition. Vapors are heavier than air and may travel

considerable distances to a source of ignition where they may cause a flashback or explosion. If container is not

properly cooled, it can rupture in the presence of excessive heat.





================== SECTION 6 - ACCIDENTAL RELEASE MEASURES ====================

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:

Keep all sources of ignition and hot metal surfaces away from spill/release. Use explosion-proof non-sparking

equipment. Stay upwind from area. Isolate danger and keep unauthorized personnel out. Stop source of release if

possible with minimal risk. Wear appropriate protective equipment including respiratory protection. Prevent spill from

entering sewers, storm drains, or any other unauthorized treatment drainage systems and natural waterways by diking

ahead of the spill. Spilled material may be absorbed with an appropriate spill kit. Notify fire authorities and

appropriate federal, state, and local agencies if required.





==================== SECTION 7 - HANDLING AND STORAGE ==========================

HANDLING INFORMATION:

Employees who come in contact with this material must be trained in accordance to 1910.1200 of the Hazard Communication

Standard.



Open container slowly to relieve any pressure. Bond and ground all equipment when transferring from one vessel to

another. Static charge can accumulate by flow or agitation. Ignition can occur by static discharage. The use of

explosion proof equipment is recommended and may be required. The use of respiratory protection is advised when

concentrations exceed any established exposure limits and in confined spaces. Use good industrial and personal hygiene

practice, wash thoroughly after handling, and do not wear contaminated clothing.

STORAGE INFORMATION:

Keep containers tightly closed. Use and store material in cool, dry, well-ventilated areas away from heat, direct

sunlight, hot metal surfaces, and all sources of ignition. Post "No smoking or open flame" sign. Store only in

approved containers. Keep away from incompatible materials (see section 10). Protect containers against physical

damage. Indoor storage should meet OSHA standards and appropriate fire codes.

OTHER PRECAUTIONS:

"Empty" containers retain residue, liquid and vapor, and may be dangerous. Do not cut, weld, pressurize, solder, drill,

grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may expode and cause severe

personal injury or death. All containers should be disposed of in an environmentally safe manner in accordance with all

government regulations.





================ SECTION 8 - CONTROL MEASURES/PERSONAL PROTECTION ==============

RESPIRATORY PROTECTION:

Engineering or administrative controls should be implemented to reduce exposure. A NIOSH/MSHA approved respirator with

an organic vapor cartridge should be used under conditions where airborne concentrations are expected to exceed exposure

limits (See Section 2). Use a positive pressure air supplied respirator if there is potential for uncontrolled release,

exposure levels are not known, or any other circumstances where air purifying respirators may not provide adequate

protection.

VENTILATION:

If current ventilation practices are not adequate to maintain airborne concentrations below the established exposure

limits, additional ventilation or exhaust systems may be required. Where explosive mixtures may be present, electrical

systems safe for such locations must be used.





PROTECTIVE GLOVES:

Prevent prolonged or repeated contact by wearing gloves impervious to solvents and other appropriate protective

clothing. Launder contaminated clothing before reuse.

ACHRO SEAL 1315

EYE PROTECTION:

Wear safety glasses to reduce eye contact potential. Chemical safety goggles (ANSI Z87.1 or approved equivalent) are

appropriate if splashing is likely. Eye washes must be available where eye contact can occur.

OTHER PROTECTIVE CLOTHING OR EQUIPMENT:

A source of clean water should be available for flushing eyes and skin.   Showers should be available if larger spills

are possible.

WORK/HYGIENIC PRACTICES:

Efforts should be made to minimize contact and spills.   Always wash hands before eating, drinking, or smoking.       Clean up

spills promptly. Follow OSHA and company guidlines.
