Health hazards

EPS is not known to lead to any skin irritations and is regarded as biologically inert. esidual quantities of Pentane and styrene monomer are insignificant. However during hot wire cutting adequate ventilation should be provided as fumes can cause irritation to the respiratory tracts and eyes. Where substantial dust is produced in subsequent processing of EPS (e.g. band sawing or grinding), suitable dust extraction should be provided, to ensure that exposure does not exceed 10mg/m3 8 hours TWA (Occupational Exposure Limit for total invaluable dust). b. Safety Hazards EPS is organic and therefore combustible. The following fire precautions are recommended. 1. 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. 2.Storage and working areas should be kept free from rubbish that may spread fire or ignite spontaneously. 3. Fire extinguishers and/or hose reels should be available at an easily recognizable fire point and at all times close at hand when welding or burning adjacent to EPS. 4. 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 31 of the Factories Act 1961. 5. 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.
