5.1 Extinguishing Media Suitable Extinguishing Media.Water spray, foam, dry powder or C02.
Unsuitable Extinguishing Media. Do not use waterjet.
5.2 Special hazards arising from the substance or mixtureThis product may give rise to hazardous fumes in a fire.  Hazardous the substance or mixture Decomposition Products:Carbon monoxide, carbon dioxide, styrene, aliphatic hydrocarbons and traces of hydrogen bromide can be produced.
5.3 Advice for fire fightersFire fighters should wear complete protective clothing including self-contained breathing apparatus. Chemical protection suit. Keep containers cool by spraying with water if exposed to fire. Flammable concentrations of pentane may accumulate on storage in closed containers.






6.1 Personal precautions, protective equipment and emergency proceduresCaution – spillages may be slippery.
Pentane may be present initially in the moulded material and can form explosive mixture with air. The pentane vapour is heavier than air; beware of pits and confined spaces. Remove or make safe all sources of ignition. Avoid friction, sparks, or other means of ignition. Take precautionary measures against static discharges. Use only tools which cannot create a spark.
6.2 Environmental precautionsPrevent entry into drains.
6.3 Methods and material for containment and cleaning upIf safe to do so: Small spillages: Sweep up and shovel into waste drums or plastic bags. Transfer to a lidded container for disposal or recovery. Large spillages: Use vacuum equipment suitable for use in hazardous locations for collecting spilt materials, where practicable. Transfer to a lidded container for disposal or recovery.
6.4 Reference to other sections
See also Section 8 and 13





Expanded polystyrene (EPS) is a CFC and HCPC free material and is physically and chemically inert. It contains no known biological or physiological irritant.
Static build up whilst transferring EPS Bead can create a fire risk. Ensure EPS bead is transferred at slowest speed possible and that all transfer equipment is suitably earthed.
EPS is organic and therefore combustible. Although not exhaustive the following guide line and recommendations should be included when assessing the fire precautions of EPS product
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 and therefore no smoking and naked flames must be avoided.
Individual storage areas on building and civil engineering sites, generally, should not contain more than 60 cubic metres (about 1 tonne) of material. If a bigger volume needs to be stored, it should be divided into 2 or more areas, at least 20 metres apart.
If stored outside for more than 1 week it should be covered and at all times stored in a fenced compound to avoid arson.
Large stockpiles should have consideration to siting so that if a fire occurrs the molten liquid generated is adequately bunded and cannot flow down slopes, stairs etc. The bund needs to be liquid tight and fire-resisting and have capacity 3% of the total area. Wherever possible do not store on floors above ground level. The use of sprinkler systems should be considered and adequate access ways provided.
EPS should be stored away from highly inflammable material such as paint, solvents or petroleum products. Care should also be taken to avoid contact with aromatic, oils, and materials such as coal tar, pitch and creosote.
Expanded polystyrene (EPS) insulation boards and the lighter blocks tend to be relatively light and can easily be handled on site. Although the boards can be lifted by a single person, it is recommended that the polystyrene boards are carried by two people (especially in windy conditions) to avoid injury to the carrier or damage to the boards.
When forming, cutting or shaping expanded polystyrene (EPS) care must be taken to avoid ignition by burning or hot-wire cutting methods. Adequate ventilation must be provided to prevent respiratory tract and eye irritation which may be caused by any fumes which may be generated. Forming and shaping of expanded polystyrene (EPS) must be undertaken away, and at a safe distance from, the main stockpile to minimise any risk of fire or flame spread.

8.2.3 Environmental Exposure ControlsEuropean Community and local provisions on Volatile Organic Substances (VOC), are to be fulfilled when they are applicable to the EPS industry.
8.2.4 Further information

Further protection required when handling expanded polystyrene, other than those stated under Section 16 should not normally be required, however individual exceptions may be established as the end user should ensure a suitable and sufficient risk assessment is undertaken when Interacting with Polystyrene (EPS) and its processors or operations.
EPS is not known to lead to any skin irritations is chemically stable, biologically inert and non-toxic. EPS is flammable and contains residual amounts of pentane and styrene monomer.
Precautions must be taken in storing, cutting with hot wire, bandsaws, sanding discs and applying the polystyrene material to ensure protection against ignition, contact with solvent based products and PVC-e.g. Electrical cable
Insulation-due to the migration properties of plasticisers in PVC.
Where substantial dust is produced in subsequent re-working or 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} and adequate fume extraction must be considered dependant on any hot wire process used.

Recover or recycle if possible using a registered re-cycler. Scrap expanded polystyrene is not classified as “Notifiable Waste” and may be disposed of at suitable landfill sites or by incineration under approved conditions. The Local Authority Waste Disposal Officer should be contacted for advice on the correct method to be used. Flame retardant grades contain a halogen complex flame retardant additive encapsulated in the polystyrene which can give rise to the emission of gases such as hydrogen bromide during incineration of waste product. Unofficial dumping or incineration of polystyrene waste is not allowed.
