3. HAZARDS IDENTIFICATION

Human Health Hazard

EPS is not known to lead to any skin irritations and is regarded as biologically inert. Residual quantities of pentane and styrene monomer are insignificant. However during hot wire cutting of EPS if ventilation is not adequate

.the fumes generated can cause irritation to the respiratory tracts and eyes

Where substantial dust is produced in subsequent processing of EPS (e.g. band sawing or grading), suitable dust extraction must be provided, and to ensure that exposure does not exceed 10 mg/m3 8 Hours

(TWA (Occupational Exposure Limit for total inhale able dust

Safety Hazards

:EPS is organic and therefore combustible. The following fire precaution is recommended

  • Smoking should be prohibited in the storage and processing areas.
  • EPS should be stored away from highly inflammable material such as paint or petroleum products.
  • When stored or used in enclosed spaces insure that the area is adequately ventilated for at least 7 days
  • Storage and working areas should be kept free form rubbish which nay spread fire or ignite spontaneously.
  • Fire extinguishers and/or hose reels should be available at an easily reconcilable fire point and at all times close at hand when welding or burning adjacent to EPS
  • Polystyrene dust, like other hydrocarbon based polymers in this form, is classified as a Group (a) flammable dust and precautions should be taken as required by Section 32 of the Factories Act 1961.
  • If there is an outbreak of fire, the Fire Brigade should be called immediately and advised that EPS is involved. The area should be evacuated by all personnel, except those fighting the fire

 

FIRST AID MEASURES

First Aid – Inhalation

Only dust produced from machining EPS or small particles are likely to be inhaled. Clear the respiratory tracts

.If recovery does not occur obtain medical attention

First Aid – Skin

.No specific measures

First Aid – Eye

.Flush EPS particles from the eye with water. If rapid recovery does not occur obtain medical attention

First Aid – Ingestion

No specific measures

First Aid – Fire – Ingestion of smoke or fumes

Remove from exposure into fresh air. Keep warm and at rest. If there is respiratory distress, give oxygen. If breathing stops r shown sings of failing, apply artificial respiration. Obtain immediate medical attention

Skin Contact

. Molten Material – Immediately flood affected area and adhering molten polymer with plenty of cold water

.DO NOT attempt to remove molten or solidified material form the skin. Obtain immediate medical attention

FIRE FIGHTING MEASURES

Specific Hazards

Hazardous combustion products may include carbon monoxide and carbon dioxide. Hydrogen bromide will also be released from flame retardant grades

Extinguishing Media

.Foam, water spray or fog. Dry chemical powder or carbon dioxide

ACCIDENTAL RELEASE MEASURE

.The product is in solid form and releases no harmful substance

Personal Protection                               No specific measures
Clean up Methods                                Dispose of in accordance with section 13

HANDLING AND STORAG

Store under cover in dry conditions taking into account recommendations in section 3 – Fire Precautions.Stockpiles should not contain more than 60 cubic meters (about 1 tonne). If a bigger volume needs to be stored it should be divided into two or more stockpiles at least 20m apart.
