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.
