This European Standard covers essential health and safety requirements for the design of blow moulding machines for the processing of plastics. The significant hazards inherent in blow moulding machines are listed in Clause 4.This European Standard does not cover dip blow moulding machines.This European Standard does not cover hazards due to the use of fluorine or other toxic fluids.The safety requirements for the interaction between blow moulding machines and ancillary equipment are stipulated. The technical safety requirements for the design of this equipment are not covered.This European Standard does not cover the requirements for the design of the exhaust system.The European Standard does not cover noise hazards.This European Standard is not applicable to blow moulding machines which are manufactured before the date of its publication as an EN. A transition period until 29 December 2009 is foreseen during which the manufacturer may choose to apply either this or the previous version of the standard.
