|-------------------------------------------------------------------------|
                                                                           
EMERGENCY OVERVIEW: DANGER! Extremely flammable liquid and vapor. Vapor   
harmful. Harmful or fatal if swallowed.  Vapors may cause flash fire or       
explosion.  Aspiration hazard if swallowed - can enter lungs and cause        
damage. Harmful if inhaled.                                                   

POTENTIAL HEALTH EFFECTS:                                                  
                                                                           
EFFECTS OF OVEREXPOSURE - EYE CONTACT:  May cause eye irritation.          
                                                                           
EFFECTS OF OVEREXPOSURE - SKIN CONTACT:  May irritate skin.  Prolonged     
or repeated contact can result in defatting and drying of the skin which   
may result in skin irritation and dermatitis (rash).                       
                                                                           
EFFECTS OF OVEREXPOSURE - INHALATION:  Vapor harmful if inhaled.  Vapor    
may irritate nose and upper respiratory tract.  Vapor inhalation may affect
the brain or nervous system causing dizziness, headache or nausea.         
                                                                           
EFFECTS OF OVEREXPOSURE - INGESTION:  This material may be harmful or      
fatal if swallowed.  Aspiration of material into the lungs due to vomiting 
can cause chemical pneumonitis which can be fatal.  If ingested, this      
product may cause vomiting, diarrhea, and depressed respiration.           
                                                                           
EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS:  Reports have associated        
permanent brain and nervous system damage with prolonged and repeated      
occupational overexposure to solvents.  Overexposure or misuse of toluene  
can cause liver, kidney, and brain damage as well as cardiac abnormalities.
Symptoms include: loss of memory, loss of intellectual ability, and loss   
of coordination.                                                           
                                                                           
MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED BY CONTACT:  None known.

EYE CONTACT:  Flush with large quantities of water until irritation        
subsides.  Contact a physician.

INHALATION:  Remove to fresh air.  If not breathing, give artificial       
respiration.  If breathing is difficult, give oxygen.  Contact a physician 
immediately.

UNUSUAL FIRE AND EXPLOSION HAZARDS:  Extremely flammable. Material will    
readily ignite at room temperature.  Vapors may form an explosive mixture     
with air. Vapors can travel through a source of ignition and flashback.       
Containers may explode if exposed to extreme heat.  Eliminate sources of      
ignition: heat, electrical equipment, sparks, and flames.  Do not put in      
contact with   oxidizing or caustic materials.                                
                                                                           
SPECIAL FIREFIGHTING PROCEDURES:  Full protective equipment, including     
self-contained breathing apparatus, is recommended to protect from         
combustion products.  Cool exposed containers with water.

SPILL OR LEAK PROCEDURES:  Dike spill area. Immediately eliminate sources  
of ignition. Use absorbent material or scrape up dried material and place  
into containers.

|                    SECTION 7 - HANDLING AND STORAGE                     |
|-------------------------------------------------------------------------|
                                                                           
HANDLING INFORMATION:  KEEP OUT OF REACH OF CHILDREN. Avoid skin and eye   
contact. Avoid breathing vapors. Use only in a well ventilated area.       
                                                                           
STORAGE INFORMATION:  Store away from caustics and oxidizers.  Keep away   
from heat, spark, and flame.  Keep containers tightly closed when not in   
use. Keep containers from excessive heat and freezing.  Do not store at    
temperatures above 120 degrees F.                                          
                                                                           
OTHER PRECAUTIONS:  Intentional misuse by deliberately concentrating and   
inhaling vapors may be harmful or fatal.  Do not take internally.
Construction and repair activities can adversely affect indoor air         
quality. Consult with the occupants or a representative(i.e. maintenance,     
building manager, industrial hygienist, or safety officer) to determine       
ways to minimize any impact.

|           SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION             |
|-------------------------------------------------------------------------|
                                                                           
ENGINEERING CONTROLS:  Provide sufficient mechanical ventilation (local or 
general exhaust) to maintain exposure below PEL and TLV.  Vapors are       
heavier than air and will collect in low areas.  Check all low areas       
(basements, sumps, etc.) for vapors before entering.                       


RESPIRATORY PROTECTION:  If 8 hour exposure limit or value is exceeded for 
any component, use an approved NIOSH/OSHA respirator.  Consult your safety 
equipment supplier and the OSHA regulation, 29 CFR 1910.134 for respirator 
requirements. A respiratory protection program that meets OSHA 1910.134 and
ANSI Z88.2 requirements must be followed whenever workplace conditions     
warrant a respirator's use.                                                
                                                                           
EYE PROTECTION:  Goggles or safety glasses with side shields.              
                                                                           
SKIN PROTECTION:  Solvent impervious gloves.                               
                                                                           
OTHER PROTECTIVE EQUIPMENT:  Provide eyewash and solvent impervious apron  
if body contact may occur.                                                 
                                                                           
HYGIENIC PRACTICES:  Remove contaminated clothing and wash before reuse.
