Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
High concentrations of phosphine are irritating to the eyes.
SKIN EFFECTS:
Contact with moisture on the skin may form irritating materials such as phosphoric acid. Pain, burning and
irritation may result from contact.
INGESTION EFFECTS:
Since the product is a gas at room temperature, ingestion is unlikely. Contact may be irritating.
INHALATION EFFECTS:
Inhalation of phosphine may cause coughing, shortness of breath, wheezing, increased bronchial secretions and
pulmonary edema; weakness, fatigue, headache, dizziness, fainting, drowsiness, tremors, disturbances of gait,
convulsions, and coma. Abdominal pain, thirst, nausea, and vomiting may also occur. Severe exposures (i.e.,
over 200 ppm phosphine) may be lethal.
Phosphine is toxic to the kidneys. Exposure may result in albuminuria and hematuria. Chronic exposure may
result in disturbances of sight, speech and motor functions. Other manifestations of phosphorus poisoning may
occur, including skeletal injury.

4. First Aid Measures
EYES:
In case of eye contact, immediately flush with low pressure, cool water for at least 15 minutes, opening eyelids
to ensure flushing. Get immediate medical attention.
SKIN:
Flush affected areas immediately large quantities of water. Then wash thoroughly with soap and water. Consult
a physician if irritation develops.
INGESTION:
MSDS: G-203
Revised: 6/12/96 Page 2 of 7
PRODUCT NAME: PHOSPHINE IN HYDROGEN AND ARGON
Rinse affected area with water. Give water by mouth to dilute. Never give anything by mouth to an unconscious
person. DO NOT INDUCE VOMITING! Call your local poison control center for advice, giving identity of
chemical.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE
PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS AND BE
AWARE OF THE EXTREME FIRE AND EXPLOSION HAZARD. RESCUE PERSONNEL SHOULD NOT
ENTER AN EXPLOSIVE ATMOSPHERE. Quick removal from the contaminated area is most important.
Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Unconscious persons
should be moved to an uncontaminated area, and given artificial resuscitation and supplemental oxygen if they
are not breathing. Further treatment should be symptomatic and supportive.
5. Fire Fighting Measures
Conditions of Flammability: May spontaneously combust at room temperature in air
Flash point: Method: Autoignition
Not Available Not Applicable Temperature: Not Available
LEL(%): Not Available UEL(%): Not Available
Hazardous combustion products: Phosphorous Compounds
Sensitivity to mechanical shock: Not Available
Sensitivity to static discharge: Not Available
FIRE AND EXPLOSION HAZARDS:
Dry phosphine is spontaneously combustible (pyrophoric) at room temperature. Hydrogen is very flammable
and rises rapidly in air. Gas may accumulate in upper portions of the building.
The potential for ground water contamination as a result of a fire exists since phosphoric acid is a product of
combustion of phosphine. Water runoff should be collected and disposed of as a hazardous waste in accordance
with local, state and federal regulations.
EXTINGUISHING MEDIA:
None. It is safer to allow the fire to burn itself out since the products of combustion are less toxic than
phosphine. If possible, close off valves upstream to shut off gas supply. Inerting the atmosphere to reduce
oxygen levels may extinguish the flame. Do NOT attempt this unless specifically trained.
Use water spray to cool surrounding equipment and fire exposed containers.
FIRE FIGHTING INSTRUCTIONS:
If possible, stop the flow of gas and allow the fire to "burn" itself out. The products of combustion are
phosphorous pentoxide (which forms a dense white cloud), phosphoric acid, and water. Control the dispersion
of phosphoric acid vapors with a water spray, being sure to collect runoff so as to prevent environmental
contamination.
Fire fighters should be equipped with protective clothing and self-contained breathing apparatus. Personnel and
equipment should be decontaminated using a water spray as a minimum. Avoid contact with contaminated
equipment as this may be corrosive due to contamination with phosphoric acid. Never enter a flammable
atmosphere. Caution should be used when determining if the flame has been extinguished. Should the fire be
extinguished and the flow of gas continues, increased ventilation must be used to prevent a buildup of gas, thus
creating an explosion hazard.
Keep non-essential personnel away from the immediate area. Use only spark proof tools to close open valves.

6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.
7. Handling and Storage
Earth-ground and bond all lines and equipment associated with the system. All electrical equipment should be
non-sparking or explosion proof.
Post "NO SMOKING OR OPEN FLAMES" signs in the storage area or use area. There should be no sources of
ignition in the storage or use area.
For additional information, consult the Compressed Gas Association (CGA) pamphlet P-1.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas and emergency exits. DO NOT allow the temperature where cylinders are stored to exceed 125oF (52oC).
Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty
cylinders should be segregated. Use a "first in-first out" inventory system to prevent full cylinders from being
stored for excessive periods of time.
Valve protection caps must remain in place unless container is secured with valve outlet piping to use point.
Close valve after each use and when the container is empty. Do not drag, slide or roll cylinders on their sides.
Use a suitable hand truck for container movement. Use a pressure reducing regulator when connecting container
to piping or systems. Do not use gas directly from container. Do not heat container by any means to increase
the discharge rate of product from the container.
