General hazard identification The rubber contains antioxidant of amine, phenol or
amino-phenol types to prevent destruction during
storage, transporting and at first stages of processing.
The rubber also contains non-polymerized 伪-methyl-
styrene. At normal safe conditions these substances are
not harmful.
Other information The following antioxidants are used as stabilizers:
BS-1, Trinonylphenylphosphite, Santoflex, Wingstay T.
As for the influence upon human organism these
antioxidants are not dangerous. The rubber is available
in the form of briquettes weighing 30卤1 kg.

3. Hazard Identification
3.1. Kinds of influence
3.1.1. Synthetic Butadiene-a-Methyl-Styrene Rubber is a
substance of little danger. At elevated temperatures and
when processed the rubber has a weak odour of residual
monomer -alpha-methyl-styrene. The content of non-
polymerized monomer in the rubber is 0,05% max, and it
is not harmful when industrial hygiene is observed.
The antioxidants are dangerous only when the rubber is
produced. In case of fire polymer combustion products -
carbon oxides, carbon black may be dangerous.
3.1.2. Effect on human organism Inhalation, skin contact (in a melted state), eyes.
3.1.3. Affected organs and tissues The rubber is not poisonous and it causes no
pathological changes. At elevated temperature the
products of destruction, such as butadiene, alpha-
methyl- styrene, may affect nervous system, liver, blood,
kidneys.
3.1.4. Manifestation of influence
-skin contact Direct contact of the rubber with unprotected skin causes
no pathological changes. Hot product may cause burns.
-eye contact The rubber may scratch eyeballs.
-ingestion Sickness.
-inhalation The rubber is a product of low volatility, it is not irritant.
At elevated temperatures butadiene and alpha-methyl-
styrene may be isolated, which are irritant for eyes and
respiratory system.
- in case of fire Skin burns and injures.
3.2. Ecological information
3.2.1. General description The rubber has no environmental hazard. Products of
destruction (伪-methyl-styrene, butadiene) may
contaminate air, water, soil.
3.2.2. Ways of influence upon If the rules of storage and transportation are not violated.
environment
3.2.3. Indications observed Water and soil contamination. Degradation products may
change odour and taste of water and air.
3.2.4. Hygienic norms Maximum Allowable Concentrations (MAC) of the rubber
for production premises, air, water reservoirs, fishery soil
are not established.

In case of fainting, put victim horizontally with lowered
head. Give ammonia to breath in. In case of breath stop-
artificial breathing. Call ambulance.
