3. HAZARDS IDENTIFICATION
Main hazards and effects:
Rubbers DSSK-2545, DSSK-2545-M27 are non-dangerous products, according to its influence on
the health. Skin contact does not cause any irritation. Does not contain nitrosamines or nitrosamine
generated substances.
At high temperature or during the processing method, rubber DSSK-2545, DSSK-2545-M27 may
release the vapor of residual monomer 鈥? styrene and hydrocarbon solvent, used at polymerization. In
case of fire, the hazard must be identified by the present of carbon oxide.

Inhalation
In case of irritation: milk with mineral water. In case of emergency: remove to fresh air. In case of
poisoning: tea, see the doctor.
Eye contact
Immediately flush eyes with water. See the doctor.
Skin contact
Immediately flush skin thoroughly with soap鈥? solution in water. Symptomatic treatment as in case of
s
burns.

5. FIRE-FIGHTING MEASURES
Extinguishing media
Suitable: - fire blanket
- foam
- powder
- carbon dioxide
- inert gas ( in case of small fires)
- vapor
- air-mechanical foam
- water with wetting agents
- powders (in case of larger fires)
Special fire fighting procedures
Maintain the distance from the fire. Use water for rubber bale鈥? cooling.
s
Special protective equipment for firefighters
Use fireproof clothing. Wear heat resistant clothing and self-contained breathing apparatus.
Unusual fire and explosion hazards
Rubber is a fire and explosive proof product. By introduction in fire鈥? source, the formation of fumes
s
may cause the irritation of respiratory tract. Hazardous products are carbon oxide and carbon black.
Temperature of self-ignition 400掳C
掳
Temperature of ignition 315 C
6. ACCIDENTAL RELEASE MEASURES
Main precaution
Maintain the storage, transportation, handling terms.
Eliminate sources of ignition. Use the equipment without ignition source.
Personal precaution
Wear heat resistant clothing, self-contained breathing apparatus.
Environmental precautions
Use fire-fighting media, anti-fumes systems. Control of hazard ingredients.
7. HANDLING AND STORAGE
HANDLING
Advice on safe handling
Handle only in room with ventilation. Air speed should be 0,5 m/sec.
Other precautions
Storage terms: 1 year.
掳
Avoid any contamination and direct sunlight, storage temperature is no more than 30 C.
Avoid storage with acids, organic solvents and any chemical materials.
Rubber wrapped in polyethylene film and packed on the pallets, is stored in stacks in 3- layers.
Rubber packed in polyethylene film and paper bags, is stored in stacks with height no more than
1,2 ? .

10. STABILITY AND REACTIVITY
STABILITY
Product is stable in normal conditions
Conditions caused dangerous changes warming, direct sunlight over a long period of time, open fire.
Incompatible materials concentrated acids, oxidizers, and organic solvents.
Another information warming, oxygen, ozone, direct sunlight cause butadiene-
styrene rubber鈥? structure changes with decrease of its
s
physical-mechanical properties.
11. TOXICOLOGICAL INFORMATION
Acute toxicity
In accordance with significant data with possible relevance, this rubber may be referred as low-
toxicity product. Rubber processing is characterized as low-toxic. Rubber toxicity is caused by the
possible monomer, solvent and oil鈥? rest in amount significantly lower as exposure limit during rubber
s
processing and warming.
Inhalation hazards
Non-dangerous product at processing and handling.
Skin contact
Do not cause irritation with skin contact. At the same time it is recommended to keep precaution
measures, designed in 7, 8.
Main effects as a result of short time and long-time influence
There are no hazards related to the influence of butadiene-styrene rubber if all safety measures are
kept.

12. ECOLOGICAL INFORMATION
Possible environment relevance
The rubber properties do not change under the influence of environmental conditions. The product is
not easily biodegradable. Ground and water contamination may take place as a result of incorrect
rubber waste disposal and air contamination as a result of incorrect waste incineration.

exhaust ventilation. Specific safety measures are not required.
Wastes impracticable for further treatment must be disposed in special areas or incinerated in ovens
at controlled conditions.
Packing utilization
Paper sacks are intended for secondary treatment. Polyethylene packing wastes must be disposed in
places intended for this purpose.
