EMERGENCY OVERVIEW
Appearance: white chunks.
Danger! Causes burns by all exposure routes. Air
sensitive. Hygroscopic (absorbs moisture from the air).
Target Organs: Respiratory system,
gastrointestinal system, eyes, skin.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract.
Chronic:
Repeated contact may cause corneal damage. Chronic exposure may
cause effects similar to those of acute exposure.
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Substance is
noncombustible. Contact with metals may evolve flammable hydrogen
gas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Flash Point: Not available.
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 0; Instability: 1
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Cover with sand, dry lime or soda ash and place in a closed container
for disposal. Provide ventilation. Evacuate unnecessary personnel.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Discard contaminated shoes. Do not use with metal
spatula or other metal items.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from metals. Corrosives area. Do not store in metal containers.
Storage under a nitrogen blanket has been recommended. Store
protected from moisture.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.

and handling conditions. Hygroscopic: absorbs moisture or water from
the air. Phosphorous acid absorbs oxygen very readily from the air
to form phosphoric acid.
Conditions to Avoid:
Moisture, exposure to air.
Incompatibilities with Other Materials:
Metals, strong bases.
Hazardous Decomposition Products:
Oxides of phosphorus, phosphine.
Hazardous Polymerization: Has not been reported.
