3. HAZARDS IDENTIFICATION
Main hazards and effects:
Rubber SKD is non-dangerous product, 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 SKD may release the
vapor of residual monomer 鈥? butadiene and hydrocarbon solvent, used at polymerization. In
case of fire, the hazard must be identified by the present of carbon oxide.
4. FIRST AID MEASURES
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
s
case of 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 the water for rubber bale鈥? cooling.
s
Special protective equipment for firefighters
Use fireproofs clothing. Wear heat resistant clothing, 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
s
fumes may cause the irritation of respiratory tract. Hazardous products are carbon oxide and carbon
black.
Temperature of self ignition 332 0C
Temperature of ignition 292 0C
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. Avoid any contamination and direct sunlight, storage temperature is no more
than 300C. 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 ? .

Odor: Absence
900-970 kg/m3
Density:
No more than 160 0C
Melting temperature:
No more than 300 0C
Degradation temperature:
332 0?
Self-ignition temperature:
Organic solvent solubility: Soluble at normal conditions only in organic solvents
10. STABILITY AND REACTIVITY
STABILITY
Product is stable in normal conditions
Conditions causing 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, and direct sunlight cause
butadiene-styrene rubber鈥? structure changes with
s
decrease of its physical-mechanical properties.
11. TOXICOLOGICAL INFORMATION
Acute Toxicity
In accordance with significant data with possible relevance, this rubber may be referred as a low-
toxicity product. Rubber processing is characterized as low-toxic. Rubber toxicity is caused by the
possible respiration of butadiene and toluene vapor in amounts significantly lower as exposure
limit during rubber processing and warming.
DL50 鈥? 20000 mg/kg, rats
? L50 鈥? not obtained
Inhalation hazards:
Non-dangerous product at processing and handling.
Skin contact:
Does not cause irritation with skin contact. At the same time it is recommended to keep precaution
measures as outlined in sections 7 and 8 of this document.
Main effects as a result of short time and long-time influence:
There isn鈥? information on the hazards and influence of butadiene-styrene rubber if all safety
t
measures are kept.
