Autoignition Temp:212 F (100 C) (PHOSPHINE)
Lower Limits:1% (PHOSPHINE)
Extinguishing Media:Let burn unless leak can be stopped immediately.
Large fires: Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. Withdraw immediately in case of rising sound from
venting safety device or any discoloration of tanks due to fire.
For tank, rail car or tank truck: Evacuation radius: 800 meters
(1/2 mile).
Unusual Fire/Explosion Hazard:The molecular sieve is noncombustible.
However, phospine is a severe fire hazard, and may ignite on
exposure to air. Vapor/air mixtures are explosive. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Stop leak if possible without personal risk. Reduce
vapors with water spray. Keep unnecessary people away, isolate
hazard area and deny entry. Remove sources of ignition. Ventilate
closed spaces before entering. Notify Local Emergency Planning
Committee and State Emergency Response Commission for release
greater than or equal to RQ (U.S. SARA Section 304). If release
occurs in the U.S. and is reportable under CERCLA Section 103,
notify the National Response Center at (800)424-8802 (USA) or
(202)426-2675 (USA).
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.101. Keep separated from
incompatible substances. Notify State Emergency Response Commission
for storage or use at amounts greater than or equal to the TPQ
(U.S. EPA SARA Section 302). SARA Section 303 requires facilities
storing a material with a TPQ to participate in local emergency
response planning (U.S. EPA 40 CFR 355.30).
Other Precautions:

Respiratory Protection:Not required during normal system use. In the
event of system rupture and the release of phosphine: The following
respirators and maximum use concentrations are drawn from NIOSH
and/or OSHA. 3 ppm Any supplied-air respirator. 7.5 ppm Any
supplied-air respirator. 15 ppm Any air-purifying respirator with a
full facepiece and a canister providing protection against this
substance. Any self-contained breathing apparatus with a full
facepiece. Any supplied-air respirator with a full facepiece. 50
ppm Any supplied-air respirator operated in a pressure-demand or
other positive-pressure mode. Escape - Any air-purifying respirator
with a full facepiece and a canister providing protection against
this substance. Any appropriate escape-type, self-contained
breathing apparatus. For Unknown Concentrations or Immediately
Dangerous to Life or Health - Any supplied-air respirator with full
facepiece and operated in a pressure-demand or other
positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Not required during normal system use. In the event of
system rupture and the release of phosphine: Provide local exhaust
or process enclosure ventilation system. Ventilation equipment
should be explosion-resistant if explosive concentrations of
material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Not required during normal system use. In the event
of system rupture and the release of phosphine: Wear insulated
gloves.
Eye Protection:Not required during normal system use. In the event of
system rupture and the release of phosphine: For the gas: Eye
protection not required, but recommended. For the liquid: Wear
splash resistant safety goggles. Contact lenses should not be worn.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Not required during normal system use. In
the event of system rupture and the release of phosphine: For the
gas: Protective clothing is not required. For the liquid: Wear
appropriate protective, cold insulating clothing.
