=============================================================================
           Section 4 -- FIRST AID MEASURES
-----------------------------------------------------------------------------
   If INHALED:     If overcome by exposure, remove victim to fresh air 
                   immediately.  Give oxygen or artificial respiration as 
                   needed.  Obtain emergency medical attention.  Prompt action 
                   is essential.
   If on SKIN:     Immediately flush skin with plenty of water for at least 15
                   minutes while removing contaminated clothing and shoes. Wash 
                   clothing before reuse. 
   If in EYES:     Immediately flush eyes with gentle but large stream of water
                   for at least 15 minutes, lifting lower and upper eyelids 
                   occasionally. Call a physician immediately. 
   If SWALLOWED:   If swallowed, call a physician immediately.  Only induce 
                   vomiting at the instruction of a physician.  Never give 
                   anything by mouth to an unconscious person.

EXTINGUSING MEDIA
   Use agents appropriate for surrounding fires.
SPECIAL FIRE FIGHTING PROCEDURES:  Wear self-contained breathing apparatus 
   (SCBA) and other protective clothing.  Hazardous decomposition products 
possible (see Section 10).  Evacuate immediate area.  
UNUSUAL FIRE AND EXPLOSION HAZARDS:  Material can generate explosive hydrogen 
gas on contact with certain metals.
=============================================================================
           Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:  Evacuate area and 
keep upwind until gas has dispersed.  Dike spill.  Dilute with water fog 
(direct application of alkali may cause violent splattering).  Neutralize with
sodium bicarbonate.  Persons not wearing protective equipment and clothing 
should be restricted from areas of spills or leaks until clean up has been 
completed.  
=============================================================================
           Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING:  Keep container closed and 
upright when not in use.  Do not store near heat, sparks, or open flames.  
This product will attack glass, concrete and certain metals.  Store only in 
plastic containers.  DO NOT USE METAL CANS.
OTHER PRECAUTIONS:  Refrain from splashing product when pouring.  Avoid all 
contact with skin or clothing.  Empty containers may contain residues and 
vapors.  KEEP OUT OF REACH OF CHILDREN.
=============================================================================
           Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE):  In confined poorly ventilated areas, 
use NIOSH/MSHA approved air purifying or supplied air purifying or supplied
air respirators.
VENTILATION - LOCAL EXHAUST:  Acceptable
SPECIAL:  N/A
MECHANICAL (GENERAL):  Acceptable
OTHER:  N/A
PROTECTIVE GLOVES:  Wear acid resistant gloves (neoprene, PVC, butyl rubber).
EYE PROTECTION:  Full-face shield and chemical splash goggles (ANSI Z-87.1 or
equivalent).  
OTHER PROTECTIVE CLOTHING OR EQUIPMENT:  Acid resistant vinyl or polyethylene
coated coveralls.
WORK/HYGIENIC PRACTICES:  Where use can result in skin contact, wash exposed
   areas thoroughly before eating, drinking, smoking, or leaving work area. 
   Launder contaminated clothing before reuse.

=============================================================================
           Section 10 -- STABILITY AND REACTIVITY 
-----------------------------------------------------------------------------
STABILITY:  Stable
CONDITIONS TO AVOID:  Incompatables
INCOMPATIBILITY (MATERIALS TO AVOID):  Liberates explosive hydrogen gas when
reacting with chlorides and stainless steel. Can react violently with sodium
tetrahydroborate. Exothermic reactions with aldehydes, amines, amides, alcohols
and glycols, azo-compounds, carbamates, esters, caustics, phenols and cresols,
ketones, organophosphates, epoxides, explosives, combustible materials,
unsaturated halides, and organic peroxides. Phosphoric acid forms flammable
gases with sulfides, mercaptans, cyanides and aldehydes. It also forms toxic
fumes with cyanides, sulfide, fluorides, organic peroxides, and halogenated
organics. Mixtures with nitromethane are explosive.
HAZARDOUS DECOMPOSITION PRODUCTS:  Phosphorus oxides may form when heated to 
decomposition. 
HAZARDOUS POLYMERIZATION:  Will not occur.
