Move container from fire area if possible. Do not use water or foam. Avoid breathing toxic vapors. Keep upwind.

Utilize self-contained breathing apparatus with full facepiece operated in pressure demand or other positive pressure

mode.





                                        SECTION 5 - HEALTH INFORMATION



PRIMARY ROUTES OF EXPOSURE AND TARGET ORGANS

Inhalation, ingestion, eye or skin contact.

SIGNS AND SYMPTOMS OF EXPOSURE

(1) ACUTE OVEREXPOSURE

Zinc phosphide is a highly toxic hepatoxin. Poisoning affects the liver, kidneys, nervous system, and lungs. Inhalation

or ingestion may result in symptoms of headache, dizziness, nausea, vomiting, fatigue, coughing, jaundice,

paresthesias, ataxia, tremor, hypertension, dyspnea, pulmonary edema, cyanosis, shock, cardiac arrythmias,

convulsions, and coma. Contact with moist skin or the eyes may result in burns.

(2) CHRONIC OVEREXPOSURE

Prolonged inhalation or ingestion may cause toothache, followed by swelling of the jaw, and later necrosis of the jaw,

anemia, and bone fractures.

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE

Disorders of the kidneys, nervous system, and lungs.

CHEMICAL/COMPONENT LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN

None

OTHER EXPOSURE LIMITS

ACGIH TLV for nuisance dusts=10mg/m3; OSHA PEL for nuisance dusts=15mg/m3

EMERGENCY AND FIRST AID PROCEDURES

INHALATION: Remove to fresh air. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is

difficult, give oxygen. Call a physician. INGESTION: Induce vomiting immediately by giving two glasses of water and

sticking finger down throat. Never give anything by mouth to an unconscious person. Call a physician. EYE OR

SKIN CONTACT: Immediately flush eyes with plenty of water for at least 15 minutes. Call a physician. Flush skin with

water. Wash clothing before reuse.

STABILITY                     CONDITIONS TO AVOID

       Unstable      Stable Keep dry and away from acids.

INCOMPATIBILITY (Materials to Avoid)

Water, acids, oxidizers

HAZARDOUS DECOMPOSITION PRODUCTS

Reaction will produce phosphine. Thermal decomposition releases irritating oxides of phosphorous and toxic fumes of

zinc oxide.

HAZARDOUS POLYMERIZATION              CONDITIONS TO AVOID

       May Occur       Will Not occur Does not apply

STEPS TO BE TAKEN IN CASE MATERIAL IS LEAKED OR SPILLED

Eliminate ignition sources. Do not touch spilled material. Do not get water on spilled material or inside container.

Using a shovel place material into clean, dry, labeled container and seal. Neutralize spill residue with agricultural lime,

slaked lime, crushed limestone, or sodium bicarbonate. Comply with all applicable governmental regulations

concerning spill reporting, handling, and disposal of waste. Run-off to sewer may create fire or explosion hazard.

WASTE DISPOSAL METHOD

Dispose of in accordance with Federal, State, and local regulations.



                               SECTION 8 - PERSONAL PROTECTION INFORMATION



RESPIRATORY PROTECTION

NIOSH/MSHA approved respiratory devices to protect against particulate matter.

VENTILATION

General or local exhaust to maintain employee exposure below the TLV/PEL.

PROTECTIVE GLOVES

Impervious material to prevent skin contact.

EYE PROTECTION

Splash proof or dust resistant safety goggles to prevent eye contact with this substance. Contact lenses should not

be worn.

OTHER PROTECTIVE CLOTHING OR EQUIPMENT

When necessary utilize impervious clothing and other equipment to prevent contact with this substance.



                                        SECTION 9 - SPECIAL PRECAUTIONS



PRECAUTIONS TO BE TAKEN IN HANDLING & STORING

Store in a cool, dry, well ventilated area, away from acids and water.          Contact with water produces toxic and

flammable gas.

OTHER PRECAUTIONS

Eye wash fountain and quick drench shower should be available.
