- III. Inflammability
and Explosiveness :
-
- A. Inflammability :
- This product is flammable
under the following conditions : it can ignite if it
is strongly heated and in the presence of a source of
ignition.
- B. Data on fire hazards :
- Flash point : 199,00
°C, closed cup
- T° of auto-ignition

of extinction :
- Means of extinction:
- - carbon dioxide
- - foam
- - dry chemical
powder
- - sprayed water
- - alcohol foam
- E. Additional information
:
- Cool the containers exposed
to fire with water.
- F. Special techniques :
- Wear an autonomous
respiratory apparatus.
- G. Products of dangerous
decomposition :
- Carbon monoxide, carbon
dioxide and other products such as aldehydes and
ketones according to the oxidation state, aldehydes
being able to be very irritating.
-
-
- PREVENTION
:
-
- I. Storage :
- Store in a cool place, away
from any source of ignition, sheltered from oxidizing
materials, acids and bases.
-
- II. Exposure
Control/Personal Protection :
- This material will be used
in the molten form. Protective clothing against
splashes, thermal gloves, and ocular protection must
be worn to prevent wounds.
- Use the melted material
in well ventilated sectors. While working in
confined areas, use suitable respiratory
protection.
-
- III. Leaks :
- Handle as a thermoplastic
product. At the time of leaking of the melted
material, allow the product to solidify and cool. Keep
the material out of sewers and rivers by diking.
Recover and place in suitable containers for re-use or
disposal, according to local laws.
-
- IV. Waste Disposal :
- Consult local
authorities.
-
- TOXICOLOGY
:
-
- I. Experimental
Toxicology :
- In the rat, chronic
ingestion showed its accumulation in certain target
organs, such as the liver and spleen, associated with
nonspecific immune response.
-
- II. Absorption
:
- This product is absorbed by
the respiratory tract.
-
- III. Acute Effects :
-
- A. Inhalation :
- If heated it emits paraffin
wax fumes :
- - possible irritation of the
eyes and the respiratory tract, more particularly in
sensitive
- individuals
- - nausea.
- B. Skin :
- Contact with molten wax can
cause serious burns.
- C. Eyes :
- Direct ocular contact of the
melted product with the eyes can cause thermal burns
and ocular lesions. Fumes and vapors coming from the
thermal decomposition of paraffin wax can cause
irritation of the eyes.
- D. Ingestion :
- This product is primarily
inert and non poisonous. However, one must handle it
carefully, do not ingest or put some in your
mouth.
-
- IV. Chronic Effects :
- Inhalation of aerosols
(if heated) :
- - cough
- - sputum production
- - exertional shortness of
breath
- - possibility of pulmonary
damage (lipoidic pneumonia)
- - alveolitis and
interstitial fibrosis.
-
- V. Pregnancy
:
-
- A. Effects on development :
- No data concerning antenatal
development was found in the consulted documentary
sources.
- B Effects on the
reproduction :
- No data concerning
reproduction was found in the consulted documentary
sources.
- C Data on the mother's
milk :
- There is no data concerning
excretion or detection in mother's milk.
-
- VI. Carcinogenic
Effects :
- The available data do not
make it possible to make an adequate evaluation of the
carcinogenic effect.
-
- VII. Mutagenic Effects
:
- No data concerning a
mutagenic in vivo or in vitro effect on cells of
mammals was found in the consulted documentary
sources.
-
- FIRST AID
:
-
- I. Inhalation :
- In the event of inhalation
of fumes or vapors, bring the person into a well
ventilated place. If he does not breathe, give him
artificial respiration. Call a doctor.
-
- II. Eyes :
- Exposure to fumes and vapors
of overheated paraffin can cause irritation of the
eyes. Direct contact with molten paraffin wax can
cause ocular damage and burns. At the time of the
handling of molten wax, one should carry ocular
protection at any time. If an accident occurs, wash
the eyes with plenty of water during at least 15
minutes, call a doctor to take care of the wound.
-
- III. Skin :
- Exposure to fumes and vapors
coming from the thermal degradation of the product can
cause irritation of the skin. Direct contact with the
molten product can cause burns. In the case of burns,
wash the affected area with large amounts of water for
15 minutes. Do not try to remove the material fixed on
the skin. Call a doctor to take care himself of the
wound.
-
- IV. Ingestion :
- Is not an acute poison by
ingestion. In the event of ingestion, do not induce
vomiting, call a doctor.
