First Aid:EYES-IMMEDIATELY FLUSH EYES WITH A DIRECTED STREAM OF WATER
FOR 15 MINS. FORCEABLY HOLDING EYELIDS APART TO ENSURE COMPLETE
IRRIGATION OF ALL EYE & LID TISSUE. IF IRRITATION PERSISTS GET
MEDICAL ATTEN TION. SKIN-WASH THOROUGHLY WITH SOAP & WATER. IF
IRRITATION OCCURS, GET MEDICAL ATTENTION. INHALATION-IF SYMPTOMS
DEVELOP, REMOVE TO FRESH AIR. INGESTION-NEVER GIVE ANYTHING BY
MOUTH TO AN UNCONSCIOUS PERSON. HAVE PATIENT DRINK SEVERAL GLASSES
OF WATER THEN INDUCE VOMITING BY HAVING PATIENT TICKLE BACK OF
THROAT WITH FINGER. KEEP AIRWAY CLEAR. GET MEDICAL ATTENTION
IMMEDIATELY.

Extinguishing Media:USE AGENTS APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:DECOMPOSES VIOLENTLY WHEN 100% SODIUM
HYPOPHOSPHITE IS HEATED ABOVE 285 DEG C (545 DEG F) & WILL YIELD
TOXIC OXIDES OF PHOPHORUS & PHOSPHINE GAS. UNDER THESE CONDITIONS,
DO NOT EXTINGUISH FLAMES DUE T O THE POSSIBILITY OF PHOSPHINE GAS
ACCUMULATION. USE WATER SPRAY TO COOL CONTAINERS.
Unusual Fire/Explosion Hazard:PHOSPHINE GAS LIBERATED DURING
OVERHEATING OF 100% DOSIUM HYPOPHOSPHITE IS EXTREMELY FLAMMABLE &
TOXIC. IT REACTS VIOLENTLY WITH OXYGEN & HALOGENS.

Spill Release Procedures:FOLLOW PROTECTIVE MEASURES PROVIDED UNDER
PERSONAL PROTECTION SECTION. SCOOP OR SWEEP UP TO AVOID SLIPPING
HAZARD & ENVIRONMENTAL CONTAMINATION. SPILLS ON AREAS OTHER THAN
PAVEMENT, E.G. DIRT OR SAND, MAY BE HANDLED BY REMOVING THE
AFFECTED SOILS & PLACING IN APPROVED CONTAINERS.

Handling and Storage Precautions:HANDLING: DO NOT GET IN EYES, ON SKIN
OR CLOTHING. WEAR PERSONAL PROTECTIVE EQUIPMENT AS DESCRIBED IN
CONTROLS/PERSONAL PROTECTION SECTION OF THE MSDS. KEEP CONTAINER
TIGHTLY CLOSED & PROPERLY LABELED . PREVENT ENTRY OF ATMOSPHERIC
MOISTURE.
Other Precautions:STORAGE: DO NOT REUSE CONTAINERS. STORE CONTAINERS IN
A COOL, DRY, VENTILATED, FIRE RESISTANT AREA AWAY FROM DIRECT HEAT
AND SEPERATED FROM OXIDIZERS.

Respiratory Protection:WEAR A NIOSH/MSHA APPROVED RESPIRATOR FOLLOWING
MANUFACTURER'S RECOMMENDATIONS, WHERE AIRBORNE CONTAMINANTS MAY
OCCUR.
Ventilation:GENERAL ROOM VENTILATION PLUS LOCAL EXHAUST AT POINTS OF
EMISSION TO MAINTAIN LEVELS OF AIRBORNE CONTAMINANTS BELOW EXPOSURE
LIMITS.
Protective Gloves:CHEMICAL RESISTANT GLOVES SUCH AS RUBBER, NEOPRENE OR
VINYL.
Eye Protection:SAFETY GLASSES WITH SIDE SHIELDS OR CHEMICAL SAFETY
GOGGLES.
Other Protective Equipment:WEAR PROTECTIVE CLOTHING TO MINIMIZE SKIN
CONTACT. EMERGENCY SHOWER & EYEWASH FACILTY SHOULD BE IN CLOSE
PROXIMITY.
Work Hygienic Practices:WASH CLOTHYING BEFORE REUSE.
Supplemental Safety and Health

Toxicological Information:HYPOPHOSPHOPHITE ION IS AN ANALOGUE OF BOTH
THE BICARBONATE & PHOSPHATE IONS & IT IS KNOWN TO BE RAPIDLY
TRANSPORTED ACROSS THE HUMAN RED CELL MEMBRANE VIA THE ANION
TRANSPORT PROTEIN. HYPOPHOSPHOROUS ACID HAS A SINGLE PKA OF 1.1 &
AT PHYSIOLOGICAL PH VALUE IT IS PRESENT ALMOST ENTIRELY AS THE
UNIVALENT HYPOPHOSPHORIC ION. SODIUM HYPOPHOSPHITE IS AN
ANTIOXIDANT (REDUCING AGENT) & HAS BEEN SHOWN TO BE BENEFICIAL IN
BIOLOGICAL SYSTEMS BY VIRTUE OF ITS, FREE-RADICAL SCAVANGING
PROPERTIES. THE BACTERIAL GROWTH INHIBITING PROPERTIES SHOWS SODIUM
HYPOPHOSPHITE HAS POTENTIAL AS A FOOD INGREDIENT AGAI NST
GRAM-POSITIVE FOOD BORNE PATHOGENS
