scope:

This standard covers the essential health and safety requirements for the design of reaction moulding plant with the exception of metering and mixing units (for these see part 1). The significant and specific hazards are listed in clause 4 and are dealt with in this standard. This standard does not cover completely the hazards arising from the use of highly flammable additives, for example pentane used as a blowing agent (see 4.3), because these hazards depend to a large extent on the additives and process used. This standard does not cover the hazards due to noise generated by the cutting unit, which is the only significant source of noise at such plant. This standard does not cover the requirements for the design of exhaust systems. This standard does not cover the hazards arising from the assembly of separate units not supplied at the same time by the same manufacturer. This standard applies to reaction moulding plant manufactured after the date of publication of this standard. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
