proceed according to:
produce reproduction problems.
It does not present any in particular if
recommendations for use and safety regulations are
followed.
Toxic to fish and birds.
If its use is conditioned to the stored grains
treatment.
In case of discomfort, get medical assistance and
show the label or product safety data sheet. Keep
the patient under medical surveillance.
Inhalation
Take the person to the outside. Keep the patient at
rest and sheltered. .
Bronchospasmlytic and antitussives administration.
Skin contact

Ingestion
Wash with water for a prolonged time
Wash with wtaer for a prolonged time
An stomac emptying must be carried out by inducing
vomiting, gastric lavage with a solution 1 x 1000
potassium perganmanate or magnesium peroxide
until the lavage fluid does not smell like carbide.
Then, administer activated charcoal.
Physician note
Antidote not know. Symptomatic treatment.
Symptoms:
In case of intoxications due to low concentrations: ringing in the ears, nausea, vomiting, chest tightness,
distress and depression are produced. Symptoms that dissapear in the open air. The symptoms of
intoxication due to higher concentrations are: general exhaustion, nausea, stomach and intestinal
disorders with vomiting, stomach pain and diarrhea, and also loss of balance, strong chest pain and
dyspnea. In the case of intoxications for very high concentrations: strong dyspnea and cyanosis,
excitement, ataxia, an anoxemia, unconsciousness and death are produced; which may come rapidly or
after a few days by pulmonary edema and collapse, or by a central respiratory paralysis or cerebral
edema. The consequences of strong poisoning may be hematuria, proteinuria, uraemia, jaundice and
arrhythmia.

Cleaning methods
Residues elimination methods
Contain the extinguishing media dispersion. Avoid
environmental contamination. Isolate the area

maks, NIOSH/MSHA approved in combination with
filter for hydrogen phosphide. For unknown levels or
levels higher than 20 ppm. Give phosphine, use a
self-contained respiratory apparatus (SCBA) or its
equivalent.
Avoid contamination of water courses or sources
and sewers.
Collect the product mechanically, using shovels and
put it in a clean, dry and tightly closed container. Air
gaps must not exist inside the container, this would
cause its explosion by phosphine accumulation. Its
elimination will be made according to the
regulations stablished by the manufacturer.
See section 13
Section 7: Handling and storage
When the product get in contact with the environmental humidity, water, acids or alkali, generates
hydrogen phosphorus (phosphine) which at a 18.000 ppm. concentration, may have spontaneous
ignition. Therefore, the product handling must be carried out in ventilated places and store in proper
containers that avoid air gap formation, which can facilitate the accumulation of phosphine gas to its
ignition concentration.
Technical recommendations
Validity: August 2008
The product must be handled by responsible people,
who have knowledge of its properties and risks.
Store the product in a fresh and ventilated place, in
its original containers and with its seals unchanged.
Open the containers in ventilated places or
outdoors. Do not open containers in flammable
atmosphere.

Precautions
Do not allow the contact of the product with water,
acids or other fluids that may favor its decomposition
violently.
Specific measures for safety handling
Once the product has been exposed to the
environment, do not allow that the concentration of
hydorgen phosphorus (Phosphine) exceed it Lower
Flammability Limit (L.F.L) of 18.000 ppm.
Storage conditions
Store in original containers, in a safety, dry,
ventilated place and away from heat or ignition
sources. Do not store together with food or
medicines.
Recommended and not appropriate packaging
Keep in its original container. Recommended
material: common steel drums.

Section 10: Stability and reactivity
Stability
Stable at dry state, but reacts violently with acids in
humid environments producing hydrogen
phosphorus. Spontaneous ignition is avoided adding
ammonium carbamate in formualtions that releases
CO2 and NH3 . The hydrogen phosphorus oxidizes
to phosphoric acid in the presence of oxidizing
agents and atmospheric oxygen.
Materials to be avoided

Avoid the contact of the product with water, acids or
other fluids.
