Potential Health Effects
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include coughing anElectric Motor d shortness of breath.
Ingestion:
Not considered a toxic hazard but the ingestion of appreciable amounts may cause gastrointestinal
disturbance. Nausea, vomiting and diarrhea may be experienced.
Skin Contact:
May cause irritation, especially on moist or sensitive areas. May cause moderate inflammCustomized Service for Machinery ation after
prolonged contact.
Eye Contact:
May cause irritation, redness and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Asthma, skin conditions, Respiratory conditions.
4,First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of soap and water for at least 15 minutes. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids
occasionally. Get medical attention if irritation persists.
5,Fire Fighting Measures
Fire:
Not considered to be a fire hazard. When heated, may form spontaneously flammable phosphine.
Explosion:
Sodium hypophosphite explodes when titrated with chlorates or other oxidizing agents. A thermal
explosion will occur if sodium hypophosphite is heated under confinement.
Fire Extinguishing Media:
Use any means suitable foe extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing
apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
6,Accidental Release Measures
Ventilate areas of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used
to avoid dust dispersal.
7,Handing and Storage
Store in a cool, dry, ventilated area away from sources of heat, moisture, and incompatible substances.
Isolate from oxidizing materials. Keep away from all sources of heat, ignition and sparks because even
residues of sodium hypophosphite can decompose to form flammable, explosive phosphine gas. Do not
cut, grind, weld, or drill on or near this container, even when empty, because an explosion can result.
Containers of this material may be hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
8,Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible.
Local exhaust ventilation is generally preferred because it can control the area. Please refer to the ACGIH
document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, fir details.
Personal Respirators( NIOSH Approved):
For conditions of uses where exposure to dust or mist is apparent and engineering controls are not
feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g.
Iubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or
instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect woSorting Machine rkers in oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemicals safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
9,Physical and Chemical Properties
Appearance : White crystals
Odor : Odorless
Solubility : 100g in 100g of water
Boiling Point: Not applicable
Melting Point: 200C(392F0 Decomposes, loses water
Vapor Density (Air=1): No information found
Evaporation Rate (BuAc=1) No information found
10,Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Can decompose to form flammable, explosive phosphine gas.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Heat, fire. Contact with strong oxidizers may cause an explosion. Sodium hypophosphite decomposes in
hot alkaline solution an liberates toxic and flammable phosphine gas.
Self-reactive explosions can occur when hot sodium hypophosphite solution is evaporated.
Condition to Avoid:
No information found.

13,Disposal Considerations
Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved
waste facility. Although not a listed RCRA hazardous waste, this material may exhibit one or more
characteristics of a hazardous waste and require appropriate analysis to determine specific disposal
requirements. Processing, use or contamination of this product may change the waste management
options. State and local disposal regulations may differ from federal disposal regulations. Dispose of
container and unused contents in accordance with federal, state and local requirements.
