Risk marker for the primary purpose of the paint pigments
and rubber filler. Chinese medicine used on the system
ointment, zinc paste, such as Xiang Pigao
2. The impact on the environment
First, health hazards

Hazardous characteristics: magnesium, flax seed oil in
fierce reaction. With a mixture of chlorinated rubber heated
to above 215 ℃ possible explosion. Decomposition by high
fever, the release of toxic gas.
Combustion (decomposition) products: natural product of
decomposition unknown.
3. Scene emergency monitoring methods
4. Laboratory monitoring methods
Dithizone method "of harmful substances in the air of
determination" (second edition) with Hang-editor-in-chief
FAAS "harmful substances in the air of determination"
(second edition) with Hang-editor-in-chief
5. Environmental standards
China (TJ36-79) workshop harmful substances in the air to
allow the maximum concentration of 5 mg/m3
6. Emergency treatment and disposal methods
1. Leak emergency
Isolation leak polluted area, located around the warning
signs, the proposed emergency personnel wearing masks good,
goggles, wearing overalls. So carefully, to avoid dust, deep
inverted to open areas. Can also use a lot of water washing,
the dilution of the washing water into wastewater systems.
Such as the large number of spills, recycling or collection
of sound waste treatment.
Second, protective measures

treatment.
Ingestion: mistaken consumption, oral milk, soy milk or egg
white, gastric lavage. For medical treatment.
Fire-fighting methods: Noncombustible. Sound can be used
around the fire extinguishing media.
A meeting of dental materials referred to, that is, eugenol
zinc oxide cement powder
Eugenol zinc oxide cement powder: also known as the
temporary cement powder, small oxygen cream. For deep-hole
double-bottom of the bottom is not bearing materials, or for
the bottom of the single-layer material for one to two weeks
of the cavity the temporary closure of materials, used for
root canal filling material, as periodontal Cypriots join
the excipients Of governance.
Doctors often use zinc oxide as a eugenol zinc oxide as the
cement powder
For the treatment of acute itching of the skin usually in
calamine lotion containing zinc oxide, zinc oxide is used in
the convergence, the protective effect, and a small part of
a preservative effect.
[Types of] the convergence drugs.
[Storage] kept sealed. |
