:
-
- I-Stability and
Reactivity :
-
- Stability
:
- Conditions to avoid :
- Sensitive to light. Protect
from moisture.
- Materials to avoid :
- Ammonia, amines.
- Hazardous decomposition
products :
- Hydrogen chloride
gas.
- Hazardous polymerization
:
- Will not occur
- Hazardous reaction
:
- Reaction with ammonia or
ammonium salts yields fulminating gold, a heat,
friction-, and impact-sensitive explosive similar to
mercury and silver fulminate.
-
- II- Handling
:
-
- Do not breathe dust. Avoid
contact with eyes, skin, and clothing. Avoid prolonged
or repeated exposure
-
- III- Storage
:
-
- This material is light
sensitive and hygroscopic. Keep in tightly closed
containers.
-
- IV-Accidental Release
Measures :
-
- A-Procedures of personal
precautions :
- Wear respirator, chemical
safety goggles, rubber boots, and heavy rubber
gloves.
- B-Methods for cleaning up
:
- Sweep up, place in a bag and
hold for waste disposal. Avoid raising dust. Ventilate
area and wash spill site after material pickup is
complete.
-
- V-Engineering Controls
:
-
- A-Ventilation
:
- Mechanical exhaust
required.
- B-Personal protective
equipement :
- Respiratory : Government
approved respirator.
- Hand : Compatible
chemical-resistant gloves.
- Eye : Chemical safety
goggles.
- C-General hygiene
measures :
- Wash thoroughly after
handling.
-
- Toxicological
Information :
-
- To the best of our
knowledge, the chemical, physical, and toxicological
properties have not been thoroughly
investigated
-
- I-Skin Contact :
- Causes skin
irritation.
-
- II-Skin Absorption :
- May be harmful if absorbed
through the skin.
-
- III-Eye Contact
:
- Causes eye
irritation.
-
- IV-Inhalation :
- Material is irritating to
mucous membranes and upper respiratory tract.
- May be harmful if
inhaled.
-
- V-Ingestion :
- May be harmful if
swallowed.
-
- VI-Pregnancy
:
-
- Effects on development
:
- No data in humans concerning
antenatal development was found in the consulted
documentary sources.
- Effects on reproduction
:
- No data in humans concerning
reproduction was found in the consulted documentary
sources.
- Certain data in laboratory
animals (rat and mouse) showed an effect on the male
reproduction apparatus (testicles, epididymis and
spermatic cord).
- Effects on breast milk
:
- There is no data in humans
concerning its excretion or detection in
milk.
-
- VII-Cancerogenic
Effects :
- No data concerning a
cancerogenic effect was found in the consulted
documentary sources.
-
- VIII-Mutagenic Effects
:
- Data showed a certain
mutagenic effect in humans.
-
- First Aid
Measures :
-
- I-Oral Exposure
:
- If swallowed, wash out mouth
with water provided person is
- conscious. Call a
physician.
-
- II-Inhalation Exposure
:
- If inhaled, remove to fresh
air. If not breathing give
- artificial respiration. If
breathing is difficult, give oxygen.
-
- III-Dermal Exposure
:
- In case of contact,
immediately wash skin with soap and copious amounts of
water. A safety shower should be available close to
the work station.
-
- IV-Eye Exposure
:
- In case of contact,
immediately flush eyes with copious amounts of water
for at least 15 minutes. An eye bath should be
available close to the work station.
-
-
- Ecological Information
:
- No data
available.
-
- Disposal Considerations
:
- Catalysts and expensive
metals should be recovered for reuse or recycling.
Observe all federal, provincial, and local
environmental regulations.
