First-aid measures
Emergency measure - Inhalation: Remove patient to fresh air. Symptomatic treatment.
Emergency measure - Eyes: Rinse immediately with plenty of water for at least 15
minutes. Obtain immediate medical advice.
Emergency measure - Skin: Remove contaminated clothing immediately and wash skin with
plenty of soap and water.
Emergency measure - Ingestion: Seek medical attention.
Fire-fighting measures
Recommended extinguishing agent: Water spray, alcohol foam, carbon dioxide or chemical dry
agents (water stream may be ineffective) may be used. Use
water to keep containers cool.
Product arising from burning: Products of combustion may contain oxides of carbon and
phosphorus and solvent combustion products, including soot.
Product determined by test: N
Protective equipment: Self-contained positive pressure breathing apparatus and
full fire fighting protective clothing should be worn.
Accidental release measures
Emergency measures in case of spillage: Wear suitable protective clothing (see 2.3.1), keep away
from sources of ignition.
Small spills: cover with inert absorbent material. Sweep up
and transfer to suitable labelled containers.
Large spills: dike liquid with sand or clay and cover to
smother any fire. Use non-sparking metal (brass or
aluminium) shovel. Shovel into steel drums until 3/4 full.
Fill completely with uncontaminated sand or clay and seal.
Dispose of by incineration in accordance with local
regulations. Wash spill site with water.
Handling and storage
Handling: Do not handle as the substance itself. The substance should
be handled as a preparation (usually a solution in toluene).
Ensure adequate ventilation. Suitable protective clothing,
impermeable gloves, chemical goggles and a face shield
should be worn. If insufficient ventilation, suitable
respiratory protection should be worn. Exposure of the
preparation to air and other oxidising agents must be
avoided.
Storage: Do not store as the substance itself, store as a preparation
(usually a solution in toluene). Store in tightly closed
containers under an inert atmosphere away from oxidising
material, heat, sparks and flame.
Packaging of the substance and or preparation: 700 lb (~1540 kg) vat of a 40% solution of the material in
toluene. The package is a steel cylinder constructed to
DOT/CTC 4WB standards. Tare weight is approximately 300-330
lbs.

Exposure controls / personal protection
Stability and reactivity
Danger other than fire: The substance is pyrophoric and thus exposure to air should
be avoided. Oxidation products are the corresponding
phosphine oxide and phosphinic and phosphonic acid
derivatives.
Chemical reaction with water: The substance is pyrophoric, in air but does not appear to
react with water.
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of recovery/recycling: Recovery for reuse is not possible.
Industry - Possibility of neutralisation: The substance can be oxidised with dilute hydrogen peroxide
or dilute sodium hypochlorite.
Industry - Possibility of destruction: controlled discharge: Not recommended.
Industry - Possibility of destruction - incineration: Recommended method, incinerate as a solution (eg in toluene)
at a suitable facility equipped to handle pyrophoric
substances. Waste gas treatment to remove oxides of
phosphorus should be fitted. (A661)
Industry - Possibility of destruction - water purification: Not recommended.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
